Adjust clutch on Cub

[rossow (mn)]

I need to adjust the clutch-pedal travel on my Farmall Cub (SN 136038) but can't see how. There seems to be no free travel. Manual says 1" travel is needed before clutch disengages; it shows how to loosen a cap screw and rotate the clutch shaft. But my Cub has no cap screw as shown in the manual. I'm seeing no nuts, bolts or other adjustment methods. I'm stumped. Suggestions?

If you dont have the capscrew on the pedal to set pedal lash you must have a threaded rod going to the throw-our bearing and that adjustment is made underneath thru the hole in the bell housing

Are you looking on the bottom of the clutch pedal itself? There should be a bolt that goes through a slotted bracket and into the arm of the pedal.

No bolt anywhere. I've crawled under, looked with flashlight, felt with fingers. Nothing.

Is the hole I'm looking for the one at the bottom of the bell housing with a cover and gasket on it? I thought about taking the cover off but didn't want to muck something up. (My first and only Cub, so I'm learning as I go. Should stick with my four 8Ns so my ignorance doesn't come through as often, perhaps.)

the serial you listed is for a 1950, which should have the adjustment bolt just under the floor pan. However, it is not unusual for the radiator casting to be replaced, and it have a different serial number than original. The turnbuckle adjustment was replaced by the bolt on lower part of clutch pedal in early 1948.

Yes, the cover under the bottom with the wingnut is where you need to look for the turnbuckle. It does nor normally have a gasket, but if yours does expect oil to run out when you remove it. There should not be any oil in there, but yours may have the front transmission seal or the rear crankshaft seal, or both leaking and the gasket was added to prevent oil dripping out the cover.

If it has the turnbuckle just behind the throw out bearing it is a real pain to adjust. You have to take the pin out that attaches it to the bracket, and move it down and ot the side enough to turn it, all the while working through the hole in a dirty greasy spot. It has been a while since I worked on one of that type, but I think that too adjust the turnbuckle without splitting the tractor you may have to remove the pin at the top of the torque tube the throw out bracket pivots on.

If the disk is worn to the point there is no travel left in the pedal, you probably need to split it and replace the clutch.
