1937 D Clutch issues

swenson93 · Mar 26, 2017

Has anyone ever had an issue with a clutch not disengaging on a john deere 2 cylinder tractor? I have a 1937 D that I have been working on and I had it running last week and went to pull it out of the shop and went to disengage the clutch to put it into gear and I couldn't get it to disengage. When you pull back on the clutch lever you can feel the "snap" that you normally feel when you disengage or engage the clutch. But when you keep pulling back on the lever to apply the clutch brake to stop the Belt pulley the clutch acted like it was still engaged. Anyone have any ideas or input on what to look for or what might be wrong? Since finding this out I have pulled the clutch down and all the clutch disks seem to be in good shape yet, nothing broke or wore down to speak of.

What kind of shape is the pulley brake in? Sometime they will act that way if the brake is worn out. Also you can adjust the pulley brake. There is a adjustment bolt with lock nut right above the pulley brake. It may need to be screwed in to put more pressure on the brake.

The pulley brake is still in good shape. The clutch is for sure staying engaged. When the tractor is at an idle and you apply pressure with the brake it will actually start bogging the motor down to the point where it will die. The belt pulley itself has some in and out play, somewhere around a 1/2 - 3/4". Not sure if that is normal or not. The tractor has been sitting for the last 10-15 years. I am working on it for a family member and they told me it had clutch issues last time they ran it and someone had pulled the clutch apart and hadn't found anything wrong with it. I'm not sure if everything was put back together right or not when they had it apart.

Check for a broken clutch lining, if they are broke, sometimes they will catch.

The movement of the belt pulley is excessive but may be something U could live with. The clutch drive gear and back plate are one piece and behind that is a wear plate that sometimes will break and double up on itself but with that much movement in the pulley that's not likely your problem. The inner workings of the clutch is behind the pulley. Did U put a thin film of grease on the drive gear when U installed it? That helps. If the clutch toggles are worn or the "dog bones" are worn it will never work right. The clutch springs That disengage the clutch are important too. Hope this helps. U can go to Steiners web sight and look at their videos on the John Deere clutch. They are very good.

Just what half said.

Sometimes a piece of the facing comes loose and gets wedged between the remaining facing and the pressure place keeping it engaged.
