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.
