I have a Viking shop Manual but I don't want to sell it. However if you need it I will make a DVD of it if I can. I consider this just a help as there are just is not very many Viking cars still in repairable condition. You can write me @ M.L. Anderson 9111 Brightly St. Bellflower, CA 907906

A sway bar is basically a spring being made of the same material. If one wants to be very technical it?s a torsion bar that works on both wheels. It pulls up on the inside wheel when the outside wheel is forced up in a turn. Every torque has an equal and opposite reactionary torque. A good welder would probably laugh at you if you tried to get him to weld it. Would you weld a spring? I hope not! The fact that you asked a question proves that you are doubtful just as you should be. Yours, M.L. Anderson

I found this article from Australia about Valve Seat Recession, its long but may help some to understand the problem; http://www.unep.org/pcfv/Documents/VSR-FinalDraft.pdf M.L.Anderson

Partial quote from windjammer; I hate to open a can of worms, but doesn?t anybody remember Amoco gas? It was unleaded at least fifty years ago; I don?t think it ruined any engines. I never heard of anybody suing the company for burnt valves. Doesn?t anyone remember Sunoco Blue? It was colored BLUE to distinguish it from RED leaded fuel. Tetraethyl lead was colored [color:"red"] RED to tell everyone it was [color:"red"] poison . It was made for years just as you state, if Sunoco could be made without Tetraethyl lead why couldn?t other refineries do it? You don?t think perhaps that money had something to do with it. Do you believe that a lot of people who had Buick?s didn?t burn Sunoco Blue? When Aviation fuel got to be 100 Octane (PN) they weren?t allowed to use Tetraethyl Lead in large quantities as in automobile gasoline due to its fouling tendencies of the sparkplugs, this was back in the 1930s and up to the time that turbojets took over around 1955. That front line running up the front right side of the Buick block going into the cylinder head isn?t there for show it?s there for a purpose and that is to oil the valve mechanism. If you want clean oil up there make sure the line has an oil filter on it and that you change at every regular oil change. One of the things that Tetraethyl Lead did was to foul sparkplugs and the exhaust valves became fouled up with its residue. Sparkplugs now last 75,000 miles without lead in the gas, guess why. M.L. Anderson

BillV Does anyone have a sparkplug chart for 1949/50 Oldsmobiles? I have AC Delco R45S in mine and "assume" they are correct. AC R45S = Resistor by14mm by # 5 heat range by extended core nose. AC R45 = Resistor by 14mm by # 5 heat range. AC 46-5 = 14mm by # 6 heat range by .050" gap AC 46 is the old 14mm by # 6 heat range no resistor or extended core nose. AC 45 is the old 14mm by # 5 heat range no resistor or extended core nose. # 6 heat range is just one heat range hotter than a # 5. "R" = Resistor ?S? = Extended core nose sparkplug. If you have a radio you will likely need a resistor if you don't have resistor wiring.

While looking for informationaout the Mercer at Atlas Formula One I found this; "In my Mercer racing car..." in the Nostalgia section. <img src="http://forums.aaca.org/images/graemlins/smile.gif" alt="" /> M.L. Anderson

Quote from 1937hd45 I don't know the answer to your question, there were far more plug sizes available in the day than we have as new replacements. If you take a good look at the sparkplug on the left of your picture you will see that the lower portion is almost visually identical to the one that I made the sketch on the right hand side of my sketch. The only part that is really important is the lower portion, as the old sparkplug is a take-a-part which is likely older than I. I have slightly changed the sketch of mine and show the important 1.250? dimension of the right hand sparkplug. That has to be an old sparkplug as it appears to be a mica insulator. The other sparkplugs are not of interest to me at this time as I am trying to see/find the type of sparkplug used on the Mercer. I am also interested in the use of this particular sparkplug. You are correct as to the disappearance of 7/8?-18 plugs and this is why this may be of significance to Antique car people! #1. Is this a 7/8?-18 thread sparkplug? #2.Was it ever, to the best of your knowledge, used in a Mercer ?T? head engine? #3. Can you measure the 1.250? dimension to 1/32? as this is of up most importance to me and possibly to others! See new attachment! #4. Can you carefully look at the part and convey to me any significant Alpha/Numeric marking on it. Yours, M.L. Anderson

Have you tried to measure any part of the Ring Gear? I will make a guess as to the how many of the old GM cars used the same basic Ring Gear and Pinion. My guess that most if not all used the same basic setup, that is Cadillac, Oldsmobile, Buick, Pontiac and Chevrolet have the same units that are interchangeable parts. Very likely in 3 different sizes. The trick may be to find someone with a Parts Interchange Catalog first. Just how you can do this for that car I don?t know as Hemmings doesn?t have a list of people who do this service. One must also remember that these Gears/Pinions were all made on Gear machines made by the Gleason Gear Works of New York State. Since there were millions of them made even during the Great Depression and just how long they were manufactured in that particular style is also an unknown. My advice is to find someone with the aforementioned catalog. The two firms I called <img src="http://forums.aaca.org/images/graemlins/smile.gif" alt="" />

Does anyone have the type, make and information on the original sparkplugs used on the Mercer T head Raceabout. Information such as the diameter of the threads 7/8?-18 or 18mm plus the reach, believed to be a very long such as 1.125? (1-1/8?) or longer. Were they Champion, AC or what? Donald McKinsey seems to think they were either Stitt #19E or Champion #36. I have him sending me a Champion # 3Com but I don?t believe it has a long enough reach. This information is for my drawing of the proper sparkplug for this unusual engine. Also what may be interesting to me is contained in the question, ?Have any of the people who own or work on these engines ever measured the actual dimension of the cylinder where the sparkplug is inserted?? The ?Reach? is nominally the distance from where gasket sits on the sparkplug to where the thread ends, however being only a nominal dimension some of them are measured from the area on the sparkplug gasket sits on the sparkplug to the end of the sparkplug where the combustion chamber starts. See sketch at attachment. Some of the sparkplugs being used in many old engines are too short on the Reach and the sparkplug is running too cold because it is not being ?scoured? by the combustion gases. If the actual dimension on the engine measures .960? the ?Nominal Reach? of the sparkplug must measure 1.000?. This .040? difference is due to the crushable gasket after being torqued down properly.

I put an Autopluse on an old 1953 Dodge V-8 one hot Kansas City summer right under the driver?s seat but on the frame as it was the easiest place to put it. It was very reassuring to hear it pump away until it stopped and then you turned the key to start it as you knew there was fuel in the carburetor, it never failed. When the engine was running I couldn?t hear it. M.L. Anderson

John: I am glad you checked the reach as I made a mistake, after you go thru as many plugs as I have to make up this list it isn't surprising that that happened. I do not need any more plugs as the ones I have are significant for my purposes. Donald McKinsey is sending me one more which he says is the one I need to complete my study of the 7-8?-18 plugs. I have almost determined that McKinsey is completely correct in his telling me that the Heat Range ?theory? was not accepted until the 1925-1930 period altho whether or not it was by Bosch is questionable.

To Ivan; I was in communication with John Gillette who owns a Mercer and he was able to give me the Champion number of one of the sparkplugs he uses for his Mercer which is the one listed below, he also uses a Autolite 3076. The Autolite is a 5/8? reach but please note the reach on the Champion C97B which is 1-1/4? reach. C97B = 7/8"-18 t.p.i. thread, <span style="text-decoration: underline">1-1/4" reach</span> 1-1/4" reach, 1-1/8" hex, standard design, standard coil. $33.88. Edit;Dec.-21-2006 Ivan; I believe I have found the answer to the whole sparkplug problem and that is,? Just what was the original sparkplug which was very likely a Stitt #19 or 17E or 17Ex?. This sparkplug was replaced with a Champion #C97B as this is the only sparkplug that even comes close to putting the spark out into the actual combustion chamber.? The 1.05? dimension you believe is correct may very well be off .200? it is very likely 1.250? either that or the spark is generated .200? deeper into the combustion chamber. This sounds correct to me as this is a low compression engine. There is no way I can see of you coming close to this with a BG plug. The only to find the very first sparkplug in the first Mercer is to find a shop manual or owner?s manual or something of that kind of Champion catalog of that period. The only other sparkplug that is that long is a Delco AC # 17. M.L. Anderson <img src="http://forums.aaca.org/images/graemlins/smile.gif" alt="" />

Ivan; I am very curious about the original sparkplugs on the Mercers if you have the type and numbers I will look them up on Donald McKinsey?s price list and see if they correspond to any other sparkplugs. His list is very good but do not include the Reach which you have provided the .950? dimension in any case. He must have one difficult time finding the type of sparkplug as many of the old plugs do not have the numbers on the insulator or on the shell. M.L. Anderson

7/8"-18 1" RB114-1 [color:"green"] COLD - This is a number of the BG sparkplug with a 1" reach but I know nothing about it as I just ran the name up on the Internet. Edit Dec. 10-2006 http://www.bgservice.com/index.html M.L. Anderson

Ivan; The 10mm fiasco was mentioned in the book, ?THE BUICK, A COMPLETE HISTORY? by Automobile Quarterly. Pages 226-227 explain it more thoroughly than I am able, but it seems that the plugs fouled at low city driving speeds. The insulator was too big on the outside diameter and not enough gap between it and the inside diameter of the outer body which did not allow the hot gases to scour and clean the insulator body. If that was not what it was then I haven?t any idea what it was as I haven?t an old AC104 to compare to a modern 10mm plug. New 10mm?s do not have the glass/glazing coating on the insulator to help the sparkplug from fouling since about 1976 as it is not needed with computer controlled fuel injection. Packard Champion Y4 1937 10mm by .250? (1/4?) reach thru 1940 and certain models used AC 1042. Y4 was later replaced by UY6. AC 1042(?) from 1941 thru 1942 Buick 1940 thru 1941 AC104 Chevrolet 1941thru 1942 AC 104 Cadillac 1938 thru 1942 AC 104 Oldsmobile & Pontiac no 10mm sparkplugs used. All of the cars using 10mm plugs later changed back over to 14mm plugs as most of them were using before the 10mm fiasco. One must keep in mind that there were huge sparkplug changes from the late 1920s to about 1942 as they finally realized that making a lot of difference heat ranges sold a lot of sparkplugs even tho that many heat ranges were not needed, money talks we know. This was made abundantly clear when I studied the AC sparkplug chart that compares the ?G? 18mm series of sparkplug to the next ?K? 14mm series of sparkplugs. They dropped the number of heat ranges from 18 down to 8. The ?K? series seems to weigh only about two thirds as much with cost factors reduced somewhat too a like amount. I just wonder how many more could be dropped in view of the amount of sparkplugs that are dropped for various reasons. One must remember that there are three reasons for doing something. #1.The right reason. #2. The wrong reason. #3. The real reason, usually money. M.L. Anderson
