Im new to this forum! I just purchased running gear from a 1957 Chevy 3100 with Hydramatic and I have tons of questions. I got the engine, trans, rearend etc. I think im missing some pieces:
I noticed the flywheel cover was missing, was that a unique part?
I see a linkage coming up the back of the firewall but it was not connected to anything, what does it connect to. I have attached a pic.
Is the bell housing crossmember different then a 4 speed trans.
Is the brake pedal unique.
Tons more questions but ill start here! Thanks you so much, im excited to be on this forum.
Hy Cozsum, welcome, I am not sure if the flywheel underpan is the same as the standard transmission underpan or not. The linkage that is not attached to anything is most likely the throttle valve linkage which goes down to the transmission, this linkage causes the transmission to shift at different times based on the throttle position, you should see if the guy you purchased the setup from has at least the rest of the linkage to the carburetor, or the whole manifold carburetor and linkage. I had that setup in a 57 one ton pickup, I loved that transmission. That transmission was also used in all the GM cars except the Buick and many other manufacturers used it, including Rolls Royce. The brake pedal is the same as the other trucks of that vintage, good luck with your project.
Thanks, I do have the carb (in pieces) and manifold, but no sign of the linkage. Does anyone have a pic of what it should look like complete? Or better yet a list of parts that are unique, I hope I have everything:)
If you send "Modelman" a PM I believe he has a complete Hydramatic equipped truck. He's a good guy, and I'm pretty sure he would be willing to help out. That throttle pressure linkage is very important to proper shifting and transmission life, and it's got some oddball geometry, so try to duplicate the factory linkage as close as possible. A Dual Range Hydramatic was the first auto trans I worked on, back in 1958! Jerry
