C135 Valve Train Torque Specs

RedWhiteandBluewoodlaunch · May 15, 2023

Hi yall, I just created this account for the specific reason that I need help and this is the best website I could come to for it. I'm currently working on my 1951 Farmall Super C with a swapped in C135 outve an old combine. The previous owners swapped it idk what happened to the original engine but eh. Anyways I can't manage to find the torque specs for the valve train assembly. It has three studs two tall one short. Now the reason I want to get the correct torque specs and not just feel it out is because I do not think this motor has ever been rebuilt, it had what is most likely the original cork valve cover gasket and the original torque specs. Now this motor fired up first try every time so I want to get the correct torque specs so she'll still fire first time and have no valve issues. Any help is appreciated folks!

Hello R, W and B welcome to YT! I have access to a very detailed IH published repair manual for your engine.
It actually refers you to a bolt size chart for torque on the engine fasteners except I believed it gives a value for the head bolts. I am not going to take the time to look up the fastener sizes you are asking about and translate the torque values for you. I will not post a link here to the manual because the hosts of our forums also sell repair manuals. If you contact me through the forum safe mail I will respond with a link for you to access it. You have to be logged in to see the email buttons at the bottom of my replies.

I just torqued her down to 35 ft/lbs. I saw someone else post that they did that with their C-152 and the 135 & 152 share a lot of specs it seems like.
