Clutch failure?

Running a Toro 30498, 48" w/b.

My clutch started screeching today. Hesitant to grab, then screeches while engaged, and doesn't properly disengage.

Clutch is a GT1-TR01, 070426 by Ogura.

I'll gap the thing, but I don't see how a loose gap would lead to screeching and failure to disengage.

Can this thing be disassembled and cleaned up? I'm wondering if oil or hydro fluid might be in it...

If it's toast, I can't find this exact model clutch and am searching for a different model # that is a proper replacement.

Thanks.

That's exactly what happens to some when they wear out of proper air gap specs, Set it at .012".

You can spray the clutch down the automotive brake clean to remove any oil but blow it out good before engaging.......

Use the Toro part #105-2635, I found this one the cheapest in a 5 minute search; http://www.mowpart.com/105-2635-toro...brake-asm.html

The official gap calls for .015 - .021, so I gapped it at .018. I also sprayed 2.5 cans worth of brake cleaner all throughout it.

No improvement. Screamin' demon.

So do you think tightening the gap will help?



Found this unit, though I've never heard of the store:

Ogura Clutch
(scroll to the last one.) - I could 2nd day it for $310ish...

I gapped it again. No luck.

Thanks for the assistance, though.

the loose gap would cause the clutch to lock up at a higher rpm but with lower torque, causing it to slip, heat up allowing the matting surfaces to glaze/ warp. The heat plus the wider gap probably weakened the springs.

If you are able to disassemble/ rebuild, dna and compressed air for clean up works great.

Thanks for the feedback. Especially for the link to a cheaper unit! I don't feel nearly so put out over a $214 part.

In a nutshell thebwide gap makes it hit harder. Whereas if it not wide enough will cause it to chatter . Prekvios post was more toward a different application.

As a conclusion to my story, I found that I had a failed cylinder leaking oil directly down into the clutch. Gotta love it.
