1916 Hudson Valve Springs

[M&M]

I was wondering if anyone out there had any ideas on Valve Springs for an early 1916 engine. I have Egge looking into it, and was wondering if there was anyone that anyone uses on the east coast as I am in VT. Any suggestions would be much appreciated.

Thank You

Matt

Matt, Do you know what the installed height is, pressure at installed height, valve opened pressure ? How many springs do you need? I may be able to run off some for you. Dan

You would probably enquire of a versatile spring manufacturer rather than a piston specialist. There are two here on my side of the greater Melbourne area who are economical, obliging, and do precise high quality work. (one of these is only a few hundred yards from a foundry that cast a number of new paired T-head cylinder blocks for someone in USA for Pierce Arrows very recently. And postage of a dozen small coil springs to USA from Australia should be more economical than freighting cylinder blocks.) If you give the wire diameter, inside diameter of the wound spring, the overall length without load, the load at stated valve open length, and the number of turns, I can check out these places next time I go to Melbourne.

According to my Thompson Motor pars book, the valve spring number is VS71 for all springs for 1916 (models H, J, M, O, Super Six) all the way to 1926. Also on the 1927 -1929 Hudsons exhaust valves only. Also the Essex 1918 - 1923 Four cylinder used this spring on the Exhaust valves only.

This may be a long shot, but Rock Auto has VS71 listed in stock. They give all the dimensions. Go to site and search for VS71.

Who recomended a piston manufacturer? Just curious. Dan

Thank you all for the information, I really do appreciate it. I am going to send a pic of the spring, please excuse the grude measurement. I am without a micrometer or valve measureing tool to tell all the exact compression ratio specifications.

I was turned on to Egge Machine shop when I had a 1920 Studebaker Big Six engine rebuild. In there catalog they had a listing for a 1916-22 Super six engine rebuild kit. I called and asked the sales clerk if in fact they had springs with 10 rung as you can see for a high compression head and not the 13 rung as are standard for later models Hudsons. Just to give a little history on the car, we believe this to be an early Hudson Super Six engine, as the stamping on the block is, (A 4070) body is a center door Open Touring Sedan poss (1915) early Biddle and Smart #583 all original the car is being preserved rather than restored.

I have three damaged springs, they are conical in shape at present Egge has one of the springs as an example, but at this point I am starting to get responses from car enthusiest and will retain the spring back from Egge.

As far as having them made that is the possibility that I am looking at, just want to go the correct route and am willing to follow through with having them done. I am in contact with the members of the Hudson Clubs and am hoping to find some springs either newly manufactured or would be great to find NOS if poss. I know finding is a needle in a hay stack, but if you look at the car it was found in a barn notice one year ago two miles from original owner we are the third owners.

I can be emailed at grnmtbyz@hotmail.com or reached by phone at 802-457-1963. I thank everyone for the response and will consider and contact.

Thank you

Matt and Mike Maya

Hello,

for some reason the spring pic did not send, I will try again if not the pic is in this same category sent around early June it is under 1916 valve if anyone wishes to view.

Thank you again Matt

There is no need to guess widely about the build date of these. On the carburettor side of the block you will find the casting date. The order is month, --

day,-- year. the year number is abbreviated, having only the last one or two digits. The casting date will be a while earlier than the assembly date, because they did not know how to heat treat the raw castings for stress relief then. Jerry Gebby wrote to me that Buick had trouble with this when sales increased unexpectedly in the early 1920s, and they used up the rusty pile of castings in the yard. So they built a conveyer to take block castings from the foundry by as long and circuitous a route as possible so they were cool enough to machine. So they suddenly developed problems that had never arisen before. The Buick 6 engine had an integral head, and the valve cages were held tight by castellated ring nuts. They had incureable leakage past the valve cages, and of course piston blowby because the bores had distorted after they were machined. They redesigned the block with a detacheable head before they traced the reeal cause of their problem. I understand that Jerry Gebby worked for buick at the time, but was a Duesenberg owner and authority in later years. (Srry it has taken so many words to illustrate why the casting date is usually quite a bit earlier than the car.)

One of my friends used to have a 1918 Hudson, that was a front end of a town car with a wooden "ute"or "pick-up"back. It cost him five pounds from a farm, where it had been shedded for many years with about twelve thousand miles on the speedo. It had beaded edge wire wheels, and a broken crownwheel and pinion.

hello there

if you cannot find the springs try lester harris in minden nevada,he most likely have these,lester has been in the antique auto parts business for at least 40 years that i know of,while hes probably in his mid eighties now hes sharp as a tack,probably knows off hand what they are and how many hes got

Thank you Dave,

Found Lester Harris on youtube, and will give the gentlemen a call. thank you for the lead.

I am sending a pic of the casting on the block, if you have any info inregards that would be great.

Thanks

Matt, that doesn't look like a casting number to me. I believe it to be the motor serial number. My '14 Hudson 654 has it's serial number on the crankcase arm very much like yours, not cast, but stamped in. Seems like someone would have the range of engine serial numbers for the model year1916. Good luck in your search--Bob

[Seldenguy]

Matt; I just sent you a PM with some info on contact people in the Hudson Club both for info and parts . Good luck---Bob
