Recommended Posts

This is the first time seeing this problem on my 1978 C -101....the PTO housing gets so hot while the tractor is running at idle and disegaged that its trying to melt the belt to the pulley groove.....any ideas? Thanks guys! :thumbs:

I would take the pto off and check the bearing inside for damage, and make sure that the retainer clips for the bearing sleeve are intact.

One or both of your bearings have gone bad.

As JimD said, check the bearings. There are only three "friction" areas inside the PTO that could cause heat, #36, 38, & 43.

36 & 38 are bearings, and if they are seized, you will get hot. The other area is the clutch plate. If the pulley housing #37 is not pulling back from the plate far enough, you will also produce heat.

THANKS GUYS...I'LL CHECK THOSE AREAS....SHOULD THE BEARINGS BE GREASED OR DRY?

I looked at it a little closer today....I replaced the race that is secured to the clutch plate about 3 years ago...the pulley assy when placed on the race has a little side to side play and there seems to be a little roughness in the bearings when spun by hand....Its funny though that my original owners manual says nothing about lubricating the cage type bearings.......but I believe I was told by Pohlig's in Richmond about 12 years ago that I should use white lithium in that area....The only source of heat buildup at idle and pto disengaged should come from the bearings....I will admit there wasn't a whole lot of grease inside the pulley...What do you guys think? :thumbs:

If the bearing has play and feels rough, replace it.

maybe your brake pad is actually working and the friction disk is creating alot of heat if one side is stationary and the inside is spinning it will create heat,just a thought

What would be the correct procedure for replacing both bearings? Looks like lock ring & stub shaft should be removed first then press out smaller bearing from back side then larger bearing?

You're correct. It's not difficult at all.
