Overrun Clutch

Gizmo36 · Sep 20, 2006

I got a Overrun Clutch about a mouth ago, put it on for about 15min .Just to see how it would do. Today was going to bushhog It run about 45min. then the pin came out , It make a lot of noise when it came off.does these pin fall out of these overrun clutches easy. would it be best to just put a bolt back in it. or get a pin and put it back.

That looks like the one I have but , mime has a pin & a spring (quick disconnect type ) That one looks like mine with missing parts .Did you have to drive the pin on when you installed the unit ? The ones I've seen that you have to drive the pin through usually don't just fall out , you have to drive them out with a punch

That looks like a quick disconnect version. I had/have one identical in appearance. Not sure where you got yours. My first one lasted about 2 days and the "clutch" parts all fell out. The dealer did replace it and so far so good. There is supposed to be a spring load pin that allows you to put on/take off. How old is that one??? I would try to get dealer to replace. Sure seems to be some cheap shoddy overrunning clutches out there. Perhaps the viets will start a reconditioning business!

That's what I'am thinking If it is quick disc. version, he needs to take it back as parts are broken/ missing

It is a quick disconnect , I ran it for 45min and the pin & spring fell out . I was wanted to know if the quick disconnect were bad at that. if they are I would just put a bolt in it. It came from Hoye so i would think it was a good one.

That IS the Quick Disconnect over-running clutch..........Thats the first i've heard of one doing that....But hey, anything's possible......Seems like it could potentially lead to a dangerous situation if not careful...........If I had to guess, I would say that it is a manufacturer's defect......After all, it IS man-made.......I would return it and get another one......I am assuming that it is under warranty?

Just asking, but was you running the PTO in the #1 position?.........IF you were running it at a FAST PTO rpm, that maybe could've had something to do with it?

I would say you could install a bolt. I would make sure it is automotive grade or better. If I remember correctly the quick disc. clutch cost more than the standard. It's up to you . I would send it back for a new one cause I like the quick disc. feature

Travis_R · Sep 20, 2006

Again, IF its under warranty, there's no question as to what I would do.

Like kenmac said, the Quick Detach is a nice feature and you could probably use a bolt....

BUT you paid the money for the Quick Detach feature.......I would want to be able to use it, myself.

And hey, I'm sure Hoye wouldn't have a problem exchanging it......You should call them ASAP.....They'll stand behind ya'.........Thats what I would do, my friend.

very interesting that you say it came from Hoye. So did the one I had that came apart after approx 5 hours of mowing. The clutch came apart and I had pto shaft flying around. No damage done but does increase the pucker factor. Thats why I said your's looked just like mine. Seems to me those are some very poorly made overrunning clutches. Not sure where they are getting them from but betcha it's overseas where work is cheap!!!

The same thing happen to me a few years ago when I was installing a rotary mower on my old Farmall. When installing the quick disconnect over running clutch on the Farmall's PTO, I noticed that the spring didn't pull the locking pin all the way into the circumferential slot encircling the pto shaft. I thought that there must have been a burr on the pto shaft and the pin would work its way into the slot during initial moments of operation and thus lock the clutch onto the PTO shaft. WRONG!!! Without the pin fully seated, the clutch worked its way off the PTO shaft in just a few minutes, and the shaft went flying around, breaking the spring retainer off the end of the locking pin and throwing pieces of the locking mechanism everywhwere.

Of course, I lost the pin , spring, and retainer in the field. I didn't have time to get new parts, so I drilled the hub of the overrunning clutch in line with the existing hole in the PTO shaft for a cross pin (actually a bolt). Twenty years later, the clutch is still on there.

So, at least in my case, the problem was not equipment failure, but operator error.
