Thiokol 1201 questions

New to this thread and could use some help with my sprite snowcat. I have owned this machine for about 15 years and have a renewed interest in it. That being said it’s time for a new clutch. It has a manual 4 speed transmission attached to the industrial six cylinder motor. Where would I find a clutch, pressure plate and throw out bearing for it. Not much information out there for the clutch replacement. Also how would one find out what year this was with the serial number of 357. Any help would be greatly appreciated.
 
A build sheets exists for each machine that includes the year it was made/delivered. I think Dan at Snow Cat Service (dan@snowcatservice.com) might be able to help you on that front.

On the engine resides a plate with the engine serial number and type. Encoded in the type is the year the engine was made. I believe the first letter indicates the decade (C means the 1960's) and the next number is the specific year so C6XX-XXXX-X is 1966. Lots of web sites contain the Ford decoding info.

Thiokol used standard automotive parts. Figuring out which vehicle they came from is the trick. For engine parts, find a Ford car/van/truck with the same size engine and year and get parts for it. I use a 1965 Falcon 170 CID for my Spryte engine parts. Who knows, maybe you can do the same thing for the clutch parts.

Thanks for the info
 
Do you have the manual for Spryte's with serial numbers 095-462? On mine, someone jotted a few notes which might be useful.

Mine had a 9" clutch.

Its not a car.

I suggest a bronco with 170 cuin engine.

All fit perfect.

Mustang clutch was too small

Having trouble getting the bell housing off.
Did you have to use some kind of puller to remove thee brake rotor. As soon as I get it off I will compare it to the bronco. Thanks for the input.
