IH 595 Clutch

Ronny Perryman · Oct 4, 2013

I purchased a IH 595 tractor that acted like the clutch was worn out. You had a long let out before it caught and then if you were pulling a moderate load you could feel it slipping. When I replaced the clutch and pressure plate, but the one I took out didn't look all that bad. Put the new one in and it acted the same way as the old one. It almost seems like the clamping force on the clutch/pressure plate isn't enough to keep it from slipping.

If the flywheel is a two step style, it"s quite possible that someone has refaced the clutch surface of the flywheel and not the lip where the pressure plate bolts to. this will reduce the force of the pressure plate

There are two different flywheel/clutches for a 595. The 11 inch clutch has a flywheel step of 1.443. The 12 inch clutch has a flywheel step of 1.408. It's possible that a machine shop ground the flywheel to the wrong step spec. I think this is where you need to go look to see what you have. Let us know what you find.

I just got done putting a new clutch in a 674. No free travel left, bearing was back against the clutch housing. When I got it apart the disk did not look to bad. The step in the flywheel was about .050" off of the correct dimension.

Hi agree completely. did one in a 695.
I always take the specs to the machine shop and tell the boss what I want done, so I know the kids in the back get it right the first time!
isn't that constant running release bearing a dumb thing.
This guy uses his tractor for match plowing, so we converted it to the old style with free play on the bearing, and a slightly stiffer return spring. Hopefully he won't wear the bearing so quick, with his foot resting on the pedal all the time!.
