cub clutch won't release fully

tomga · Apr 21, 2011

cub clutch won't release.pedal goes almost to bottom before starting release.has new throwout bearing. pressure plate 2 years old.has not been right since neighbor replaced pressure plate. rod from clutch to pedal moves normal range when checking with tractor is split. maybe he overlooked something with the pressure plate. I appreciate any ideas.

Did he set the release fingers on the pressure plate to spec before putting the tractor back together? The fingers don't come adjusted on the new pressure plates anymore.

What does your pedal free travel measure? It should be about an inch IIRC, but it's specified in the owner's manual.

If you do end up splitting it again, the fingers should be 1 1/4" from the top of the finger to the top surface of the pressure plate !! Craig

The best way to insure you have the exact 1/8" clearance between the fingers and the throw-out bearing is to adjust it in the tractor throuh the inspection hole on bottom. This is not easy but it can and should be done. Then adjust your 1" of free play with the adjustment on the clutch pedal. I'm talking about if your tractor has a graphite throw-out bearing. All fingers have to be exact spacing because this type of graphite bearing does not turn.

In some clutches it makes a difference which side of the disc is toward the pressure plate - putting it together facing the wrong way can cause problems like your having. I'm not sure if this is the case on a Cub though.

thanks for your suggestions. I'll ask if he adjusted the fingers on the pressure plate. At 85 years he may have missed something.

I learned that the hard way on my Cub several years ago. Whenever I had bought rebuilt clutches in the past they were preadjusted. I attached the motor to the torque tube and discovered I couldn't adjust the clutch. So I split the tractor again and adjusted the clutch on the bench. Turned out I split the Cub a third time when I found out the main drive shaft PTO splines were bad. Roger

Personally, I'd split it and do everything correctly. Adjusting the fingers thru the inspection hole is just about impossible unless you have the hands of a child. After the split, also make sure the pilot bushing is properly lubed - better yet, replace it for all of $7 !! JMO. Craig

I bought one it is was supposedly adjusted. Not sure who it came from, but I just threw it in and went. I bought it from a local tractor fixer guy from an aftermarket supplier. I could also tell it was adjusted because it had that funky paint/locker stuff on the outside of all the nuts/bolts.

Maybe "just about" impossible, but not totally impossible. I managed to do it with my big clumsy sausage fingers.

However, I do recommend removing the belly mower if there is one installed, for reasons of self-preservation. There's still a hole in the back of my head.
