Had an interesting conversation today with the great grandson of Rollin White.........who owns a bunch of White steam and gas cars...........he agrees with the 30hp chassis ID. Also, he schooled me in White car and truck axels, hubs, drums, ect..........talk about getting information from the horses mouth! He agreed it’s some kind of strange special..........he has NEVER seen ANY White gas car with a pressurized fuel tank, and all the other items I listed as unique seem to fit with some sort of test platform. Even the casting date on the engine is in a different location to the production engines. I’m hoping that a lighter chassis makes stopping, steering, and driving easier......and with it about 1/2 the mass of the big 17..........it should go like hell.

Bridgeport/LeBaron would use body hardware from a Syracuse New York company at this time......who’s name now escapes me because of advanced age. I like the town car.........just too many interesting cars in my life and not enough time to play with them all. We need a forum billionaire to take our advice and buy/restore/preserve all the cool stuff we come across........hell, we could make Musk or Bezos from the two richest guys in the world to lowly poor car collectors.

AJ- making you look smart isn’t an easy thing! 😏
If you really want to make friends and influence people, give me fifty pounds of hundred dollar bills........I’ll pass them out and tell forum members it’s complements of AJ............hell, they may even start to like me if I’m handing out cash!

I think the splash pan doors lock it down to my first thought..............Bridgeport Body/LeBaron..........the car is right around the name change/company sale. Makes perfect sense............It looks like Ralph Robert’s work and I think that by that time, Ray Dietrich was already gone. I would need to read the company history to be certain.
LeBaron was doing a lot of design work for Springfield Metal Body at the time.........similar construction and DNA to all the New England custom builders.

Ok.......my best guess to AJ on the phone today (AM) will prove correct. Always go with your first thought.......
Below are both Loco’s.......with identified builders.........

George.......I disagree. Windshield frame looks like a Hartford product to me.........similar to what many American customs were using.........Lincoln, Locke, ect......... I still think a French body would have European lights..........I was thinking Springfield Metal Body Company......they did lots of Loco’s. The hardware wills definitely define it as American or European. Bumpers look like Weed Manufacturing.......another American product..........on a small production chassis at the end of their run.........could be any combination of things...........the splash pan cabinets are also a clue.........fun automotive archeological puzzle.

Before someone accuses me of taking a "cheap shot" at such cars or their owners, I'm not. The cars are pieces of art and more power to the owners who can afford them. That said, I don't think I'd want to own such a well-known car even if I had the resources to do so. Seems that sort of attention would make the car and me prime targets for various evildoers. I'll just continue driving under the radar in ordinary cars.
Duesenbergs, V-16 Cadillacs, DV-32’s....ect.They are just old cars, with more problems and issues than a Ford T. I enjoy my one cylinder car just as much as my V-12. price is irrelevant......I enjoy history, early auto technology, and for just a short few moments going back in time...........

One would think, if it was a French body it would have French lights and wheels on it........ certainly a cool car, with decent looks for a town car. Hood looks like a 1931-1932 replacement off of another vehicle. Photos would be a great help.......especially door hardware and hinges. I hope someone takes on the project. I see some body traits that make me think it's one of the northeast builders..........more photos would be a great help.

Back in the early 90’s Massachuetts would not let you title a car as a limousine unless you had livery insurance......which was something like 10k a car per year back then. I had my 1931 Cadillac titled as a limousine, but not registered until it was sorted. How did I solve the problem and get it registered and insured?......simple bureaucratic logic. I bought them in the sales catalog showing that it was an Imperial Limousine. The law only applied to limousines. I pushed the registry to show me where it said imperial limousine in the law......it didn’t. And I was able to register it normally.

Gary, my bad.....I used Penrite OO from restoration supply..........my memory is a bit mushy. I agree with something too thick could not flow enough. Lots of people are using corn head as a “modern good for everything” application.......and I have serious reservations about it for anything pre 1950. Since it’s thixotropic it really doesn’t flow well in slow moving applications.

OK....so from the above, and videos, I am still of the opinion "corn head grease" is different from, and flows differently from regular 'OO' grease, and I will bow to what out talented resident engineer Gary A says...........that said, Gary........is there a difference from "corn Head" to "OO"?
In my steering boxes, I have been using Lubriplate but it is so thick, we remove the box/cover and spoon it in to get the box full.......as it will not flow into the box with heat in a funnel even after 48 hours.........

POLY = MANY
EDITORIAL, “POLYUREA FOR DUMMIES”.Polyurea greases are becoming an interesting alternative to more conventional soap-based products as demands increase to be able to tailor different physical and chemical properties towards specific applications. In itself, the word polyurea is derived from two Greek words, πολυ – poly, meaning “many”; and ουρ›ας – oûron, meaning “to urinate” (the latter term referring to the substance urea found in urine, rather than urine itself). The implication of “poly = many” is that there is obviously not just one type of possible polyurea grease but a whole cavalcade of molecular combinations, all with different structures and properties. According to an anonymous source within the lubricants industry, “polyureas are like women; there are many and they are all beautiful”. A veritable dream for any creative grease formulator? In “simplistic” terms, according to Wikipedia, polyurea is a “type of elastomer that is derived from the reaction product of an isocyanate component and a synthetic resin blend component through step growth polymerisation. The isocyanate can be aromatic or aliphatic in nature. It can be monomer, polymer, or any variant reaction of isocyanates. The resin blend may be made up of amine-terminated polymer resins, and/or amine-terminated chain extenders”. Or, in even more casual terms:
isocyanate + amine = polyurea
Polyurea greases are almost always chosen because of their high temperature properties. Art Polishuk,
in his tome, A Brief History of Lubricating Greases, claims that “one of the unique properties of polyurea greases is that they tend to thicken with an increase in temperature. This may contribute to their long performance in bearings at elevated temperatures. Their long bearing life may also be due to the fact that they contain no metals to catalyse oxidation”. Another reason for the choice of a polyurea grease may be for specific rheological properties where some versions exhibit extreme thixotropic behaviour and can be made mechanically instable by design. Polyurea greases represent some 4% of the total worldwide grease production. They are most popular in Japan whereas, in other areas, they have not caught on significantly, most probably due to the health and safety issues concerning the handling of the raw materials.2 LUBRISENSE WHITE PAPER 13-14

Introduction
The invention and development of polyurea thickened greases is one the most important advances in grease technology since the end of the Second World War. The technology was developed in Japan where it is still an impressive 21% of their grease market. These ashless non-soap greases are generated by the step-growth polymerisation reaction of different isocyanates and amines in various mineral or synthetic base oils. These polyurea thickened greases tend to have high temperature performance, inherent anti oxidative properties and can exhibit either high shear stability or thixotropic behaviours. These properties have recently made them the preferred choice for filled-for-life applica- tions in both bearings and constant velocity joints and have increased their importance in steel plants and electric motors. However, their positioning as multipurpose greases has been limited by the high safety required with the storage and handling of their toxic raw materials and difficulty in their manufacture and packaging. Unlike Japan, the last three industry surveys place them at under 5% of the grease market which classifies them as specialty greases.
Chemistry
Ureas or carbamides are organic compounds with the chemical formula CO—(NH2)2. The molecule has a central carbonyl (C=O) joined by two amine (NH2) functional groups. These compounds are synthesised in the body of many organisms as part of the urea cycle, either from the oxidation of amino acids or from ammonia. They are also commonly used in fertiliser, agriculture, coatings, plastics and the pharmaceutical industry. Commercial production

They were first discovered in urine in 1727 by the Dutch scientist Herman Boerhaave and were the first organic compound artificially synthesised, without the involvement of living organisms, by the reaction of inorganic starting materials, by the German chemist Friedrich Wöhler in 1828.
The term urea also refers to a class of chemical compounds that are derived from the reaction product of mono or diisocyanates and combinations of aliphatic, alicyclic, or aromatic amines through step-growth polymerisation. This reaction is a type of polymerisation mechanism in which bi-functional or multifunctional monomers react to form first dimers, then trimers, longer oligomers and eventually long chain polymers that are called polyureas.
The isocyanates and amines have the general chemical formulations, O=C=N—R—N=C=O and H2N—R’—NH2, respectively. The connecting R and R’ chains in either compounds, preferably

AGRICULTURAL EQUIPMENT
The agricultural industry is tough on equipment, just ask John Deere. Working in harsh environments and heavy crops, Deere knows down equipment is not an option. Before John Deere puts their reputation on the line with branded grease, it is put through grueling tests to make sure it can combat its toughest enemies, like extreme pressures, severe temperatures, and water – better than other greases. Engineers at John Deere have developed some of the most stringent grease performance standards in order to prevent downtime and extend the life of its
customers’ equipment. These standards call for greases that can perform in the myriad of hostile conditions their customers face every day, including hot or cold climates, wet and/or dirty environments, and even protect in the event of infrequent relubrication. Based upon many years of field-proven, hands on experience, for the most severe conditions of agricultural service John Deere recommends polyurea thickened greases. MP SD Polyurea grease is John Deere’s best multi-purpose product, and is ideal for providing top-notch protection in hostile environments.

range from 2 to 20 carbon atoms groups and can be straight or branched chained saturated, unsaturated or aromatic groups. However, in the modern grease industry, the selection is generally limited to three diisocyanates and a series of amines. The three diisocyanates are Methylene diphenyl diisocyanate (MDI), hexamethylene diisocyanate (HDI) and Toluene diisocyanate (TDI). The amines include monoamines such as aniline, dodecylamine, hexadecylamine, octadecylamine, toluidene, tertiary butyl aniline and fatty amines such as laurylamine, palmitylamine and oleylamine. They also include diamines such as ethylenediamine, dodecanediamine, cyclohexanediamine and phenylenediamine.

applications, such as on the inside bearing of the torque sensing unit on a John Deere combine. Other common grease applications on agricultural equipment include heavily loaded ball and roller bearings, steering racks, U-joints, ball & socket or other articulation joints, pin & bushings and other accessory attachment configurations that require heavy-duty protection. Agricultural harvesting equipment such as John Deere combines are multi-functional, and can be adapted to process row planted crops by the addition of a row unit. In the case of harvesting corn, this row unit is called a corn head. These accessory units contain many moving parts driven by a slow speed gear case in order to deconstruct the stalk and remove the crop. Corn head grease is a polyurea thickened, soft NLGI 0
grade lubricating grease. A hybrid between a fluid gear lubricant and lubricating grease, it functions as a robust gear lubricant when meshed in the interface between two gear sets, such as those in a John Deere combine corn head gear case. However, because it is grease rather than a fluid gear lubricant, it stays in the gear case even when a worn seal would cause a traditional fluid lubricant to leak. This grease property is described as being thixotropic, meaning the grease softens and flows when sheared, then thickens back to its normal consistency to provide a leak proof sealing barrier when the equipment is not running. Corn head grease contains all the necessary additives to resist wear and corrosion, in addition other ingredients assure that corn head grease will not wash away if

Polyureas can also be formed by the reaction of isocyanates and water to form a carbamic acid intermediate. This acid quickly decomposes by splitting off carbon dioxide and leaving behind a complex amine. This amine then reacts with another isocyanate group to form the polyurea linkage. This two- step reaction is used in what is commonly called polyurea/urethane foam formation.
The reactivity of isocyanates makes them harmful to living tissue. They are toxic and are known to cause asthma in humans, both through inhalation exposure and dermal contact. Precaution should always be taken when handling them. Exposure to diisocyanates can cause different medical conditions. Most common are respiratory problems such as a runny nose, coughing or nose bleed. In the case of the amines, it is difficult to be specific since there are many different types involved. Many of them are, however, quite nasty materials. Aromatic and structurally similar amines comprise one of the major groups of carcinogens known to man. It is
therefore of the utmost importance to avoid contact with these materials and great detail should be given to health and safety issues when handling these raw materials. However, in paradox, once they have been fully reacted into finished polyurea compounds, they are no longer harmful or toxic. In fact, some polyurea greases are even approved for use in foodgrade applications where there is risk for incidental contact.
Grease Manufacturing
Commercial production of polyurea thickened greases usually follows a three step manufacturing process. In the first step, approximately 9 to 20 weight per cent of the selected isocyanates and amines together with about 40 weight per cent of base oils are introduced in a suitable reaction kettle. The reactants can be added either all at once or sequentially for single or double kettle thickener processes, respectively. Once the blend is in the reaction kettle, it is slowly mixed from temperatures ranging from 21°C to 204°C (70°F to 400°F) for
LUBRISENSE WHITE PAPER 13-14 7
a period sufficient to cause formation of the thickener. Although, the reaction is exothermic, external heating is required to ensure completion and generation of a stable thickener complex. The NLGI grade of the thickener is pre-determined by the amount of base oil introduced at the start of the process.
In the second step, suitable liquids and solid additives are added to the hot thickener in the same kettle or to a second or finishing kettle. Portions of the remaining base oils are added to the thickener to achieve the desired viscosity grade and cool it to temperatures suitable for the addition of other performance additives. These additives include anti-oxidants, extreme pressure, anti-wear agents and dyes.
In the final step, the fully additivated grease is homogenized to achieve the desired NLGI grade. Homogenisers are preferred over colloid mills since they generate polyurea greases with better texture and can significantly adjust the NLGI
grade of the grease. Depending on the starting material and the plant equipment, the finished grease may require additional cooling prior to packaging in a suitable container.
Recently, polyurea grease manufacture has been simplified by the use of commercially available polyurea powders. These powders are generated by solvent extraction of the base oil from the polyurea thickener manufactured by the previously explained first step of the manufacturing process. The grease is then manufactured by solubilizing the powder at the desired concentration in base oils at medium temperatures with continuous mixing. Once formed, additional oil and performance additives are added to the thickener to achieve the desired performance requirements. This approach significantly eliminates the risks involved in handling the toxic raw materials but limits the types of polyurea greases that can be generated since this option is controlled by the composition of the powder.
unwanted water is present either as spray or contaminant. Because Corn Head Grease is thixotropic, oxidation resistant, and fully fortified with the proper additives it is the best possible grease for use in corn head gear cases and it also performs well in irrigation system gear cases, golf and turf cutting gear cases, and other gear cases requiring an NLGI 0 grade grease.
SEALED FOR LIFE BEARINGS
Electric motor and automotive wheel bearings are two demanding sealed for life applications where polyurea greases thrive. Operating temperatures in these applications can frequently reach 150-180°C, significantly stressing conventional grease thickeners. The dropping point test gives an indication of the temperature at which the grease will melt or the oil will separate from the thickener. Due to the
high temperatures that can be reached in these bearing applications, grease with a high dropping point is extremely desirable. Polyurea-thickened greases have dropping points of 260°C or higher. One of the most common grease degradation mechanisms is oxidation. Conventional grease thickeners are based upon the metal salt of fatty acids. Metals can have a catalytic effect on oxidation, speeding up grease degradation reactions. Selection of a thickener system which is not formed from metallic components significantly reduces this limiting factor in grease life. Polyurea based greases are completely metal-free, and as such have outstanding resistance to oxidation.
High Temperature Grease Life test results give a good indication of a greases ability to operate under extreme conditions. In this type of testing, polyurea greases can offer

operational lifetimes of up to 50% longer than conventional complex thickeners. This long grease life can extend the life of bearings running at high speeds and high temperatures.
CONSTANT VELOCITY JOINTS (CVJ)
A CVJ is a torque transmitting coupling in which the input and output shafts have the same velocity. They are used in vehicle drivelines to smoothly transmit the energy from the gearbox output shaft to the wheels. In today’s modern car or light truck, the biggest volume of grease is used to lubricate CVJs, and these greases are expected to last for the lifetime of the vehicle.
Polyurea thickened CVJ greases were first introduced in 1978, and due primarily to progressively increasing temperature requirements have grown to become the dominant thickener for
this application. CVJs are complex systems that are tribologically very highly stressed. In the most demanding cases, plunging ball joint temperatures can reach 150–180°C. Under these severe temperature conditions, the high dropping point and oxidative resistance of the polyurea thickener system allow it to survive. One primary advantage of urea thickeners is that the building blocks can be adjusted to modify the performance of the finished grease. One finished grease property that can be imparted is thixotropy. Thixotropy is a shear thinning rheological behavior of certain urea derivatives, and in the case of the CVJ application is very beneficial in contributing to reduced lubricant starvation.

LUBRISENSE WHITE PAPER 13-14 9
Polyurea complex greases are produced when calcium based soaps or complexing agents are added to the formed thickener. In addition to the excellent properties of normal polyurea grease, these agents add inherent water resistance, extreme pressure and wear protection properties that increase the multipurpose capabilities of these polyurea complex greases.
Application & Properties
Diurea greases are the most widely used polyureas in the current grease market. They can be manu- factured either with TDI or MDI isocyanates and are often designated by the specific starting materials. The TDI alkyl aryl polyurea can have dropping points as high as 250°C (482°F), excellent water resistance, low oil separation, uncanny thixotropic behaviour and superior mobility and pumpability. These performance parameters allow them to perform exceptionally well in filled for life ball bearings found in boat
trailers, fans, high speed spindles and alternator bearings, respectively. Their thixotropic behav- iour, pumpability and mobility also allow them to be used in agricultural, construction and forestry equipment fitted with automated lubrication dispensing units optimized for multiple contact zones and lubrication points. MDI polyurea greases tend to have excellent work stability and, when additivated with the suitable antioxidants, have replaced TDI greases in constant velocity joints, generator and electric motor bearings. Their superior water resistance has also made them suitable for use in continuous casting segments of steel mills. Tetraurea greases can also be used in electric motor bearings but their selection is less desirable since they tend to harden when exposed to high temperatures or stored over time. Although polyurea thickened greases are widely used in modern lubrication applications, special consideration should be taken with their selection since they tend to have low levels of compatibility with other types of greases including other polyureas.

product called the slab, billet or bloom. This intermediate steel product is then supplied to the rolling mills for finishing. The bearings which support the moving slab combine high loads and elevated temperatures with low rotational speed. This presents difficulties in creating a lubricant film between the bearing’s rollers and raceways. High viscosity base oil greases must be selected to resist corrosion and aid in sealing as a result of continuous exposure to secondary cooling water spray and hard debris contamination.
Polyurea greases have many desirable properties which have made them successful in CC applications. For continuous casters, the most widely used lubrication method is the centralized grease distribution system. These systems pump
a relatively small amount of grease at frequent intervals to the bearing. This frequent cycle keeps the bearing full with fresh grease while also purging old grease and contaminants. Good flow properties are essential for grease to be used in steel plant applications and polyurea grease possess excellent pumpability characteristics, particularly at low shear rate. The thixotropic nature of urea based greases provides an excellent sealing barrier to prevent water and abrasive foreign particles from entering the bearings. In addition, the high dropping point (>260°C) and excellent oxidative stability offered by urea thickened greases provide extended high temperature capability, greatly enhancing high temperature bearing life.

NEXT ISSUE
The next issue of the LubrisenseTM White Papers will focus on lubricants for heavily loaded applications, especially greases for open gears. Traditionally, such products have contained substantial amounts of solid particles such as graphite and/ or molybdenum disulphide. However, in recent years, doubts have been raised concerning the need for or even the suitability of using such materials in this type of product. We are pleased that Johann-Paul Stemplinger from the Gear Research Centre FZG in Munich Germany has agreed to be
our guest author and will describe wear behavior in grease lubricated gears. In addition, we will present case studies where greases containing no solids have outperformed conventional types of graphited products.
As usual, we encourage reader contribution, feedback and proposals concerning relevant topics for future issues of our White Papers.

I'm very suspect of corn head lubricant............it needs quite a lot of motion to become liquid and properly do its job. I don't think steering boxes is a good use...........I actually watched the video from John Deere explaining it's uses.........and am suspect that with its lack of flow in a steering box it may gaul over time......and certainly not get to bushings and other areas in need of lubrication. It is made to only be used in an encapsulated area..........and a shaft spinning at high rpm with little or no seals is probably not a good place to use it.......Gary, any thoughts?
