Replacing bearings in a electric PTO

Sun Feb 06, 2011 4:53 pm

Has anybody had any luck replacing the bearings in one of these electric PTO’s? It’s a Warner 5215-13 clutch.

Thanks in advance,

Stopped by the auto parts store this morning and asked the old guy behind the counter about repairing electric clutches. He didn't think the clutches were repairable.

Considering the replacement cost, I would take it apart and see.

Thanks Eugene,

This is off a high-end commercial grass cutter and I’m finding the same answer. I’m thinking the same thoughts as your thinking. The bearings feel smooth when you turn them, but when the PTO is disengaged with the engine at idle you hear a slight squeal like almost a bearing dust shield. So I don’t know if I should take the chance to see if can do the job or try to peel back what dust covers I can and try to add grease.

Jack, if you can remove the dust cover without damage, you might find you can save it. I'm thinking the bearing is crimped into place and probably not replaceable.

I don’t see any crimps over the bearings that I can see; it appears the bearings are swaged into place. Later on today hopefully I’ll get some time to take it apart. If I can do it, I’ll post pictures.

Jack,
Here are two pictures of a 184 LoBoy Electric Clutch that is disassembled. In the second set is a 'Spring Assembly" - which is what you may be hearing dragging. I am sure that your electric clutch is somewhat different - but, most of the parts should be somewhat similar.
Hope that they help you, NJDale

I got some time to take this thing apart last night. It was nothing to disassemble, remove the three nuts and it splits in half and everything is exposed. This clutch has two bearings in it and I found the upper one to be a little rough. I took the dust covers off, cleaned it up and found nothing wrong with it. Repacked with new grease it and its smooth now.

This clutch works like an A/C clutch on an automobile, but three times the size. The Cub PTO clutch that Dale illustrates appears to have a replaceable clutch plate (where the Belleville spring is attached). My clutch has no listings for OEM parts unless you search on-line for aftermarket and so for that’s bearings only.

Parts for these commercial grass cutters are expensive. I own two of these,a Snapper Pro and Ferris. I found out the parent company for these machines is Briggs & Stratton and the parts between the Snapper and Ferris are the same. Figure that one….

Thanks again for all your help.

Jack
