Allis Chalmers 5040 Clutch

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic


   Hi guys, I have a new to me 1976 5040.  6 speed with the dual clutch.  The clutch has been slipping badly (known problem when I picked it up)  I have the inspection plate removed after taking the loader frame off.  

Anything in high range is completely useless.   When I take the inspection plate off the first thing I notice is alot of grease.  Second thing is the clutch fingers are touching the throw out bearing (I think there should be a gap).    Does anybody have access to the clutch specs.  How to adjust?  Basically pages from the service manual.  

I am about a day from splitting the tractor, I only have the fuel linkage and a hydraulic line to disconnect and I can start.   I expect once I get it apart it probably needs a whole clutch kit and flywheel machined but I would like to verify if I knew the tolerances.

	Not familiar with those but My guess is someone over greased the throwout bearing? Assuming that’s what the grease zirk is for. Hopefully Gary Burnett will see the thread, he knows these tractors well.
