PTO winch

[lowy]

I lost the slip yoke , end yoke and uni joint from the winch the other day , Thankfully , just after it saved me with a long winch up a hill after blowing the front diff .

Anyway replacements ordered , keyway ordered , It just got me thinking .......How often will these keyways fail ? , should I carry a spare , I assume they fail before a Brocken shaft or uni joint ? ,

Can someone with some experience with these winches tell me what I should carry , did I loose the slip/end yoke because of a Brocken uni and no grub screw in the end yoke do you think ?
Thanks all
Luke

Umm, being a perentie the key shouldn’t fail (it’s not a shear key or pin in the case for my PTO), the UJ might have failed which than damaged the key.

The perenties have a torque limiter incorporated in the PTO drive, when you load the PTO up too much the torque limiter should disengage drive to the winch protect the winch components.

I vaguely remember it’s spring pressure on ball bearing that the the max. torque.

If your shearing Keys than you have other problems.

I guess that the torque limiting clutch mechanism could fail to slip for all sorts of reasons including debris ingestion & lack of maintenance.

Crappy day eh?

Crappy day eh?It was a long day ,Had to winch up a long hill around corners , then needed to remove both axles , Because the front diff was binding badly , I had nowhere to remove them until I reached the top .......

It got me home tho ...so could of been worse .

I don't think I broke a key , more just lost it when the end yoke came off .
If they don't fail ....I may of over purchased [emoji4]

Thanks everyone .
PS ....if you need some keyway steel for a PTO winch

Luke there is no way that yoke can come off unless the grub screw was loose and then allowed the uni joint and slip joint to move back on the rear shaft and fall of the middle shaft. Just fix it up and loctite the grub screw with a medium strength loctite. You don't need to carry spares for these winches.

Same thing happened to mine too. I did what Bearman suggested. No problems since. link below to thread below.

Regards Warrick.Thanks Warrick ,
That's where I got the part numbers from ,
I just wasn't sure if any of these parts where easily damaged .
My mind has been put to rest

Thanks again everyone .

While you are talking PTO,s
Can the bottom PTO be reversed to drive to the rear instead of the front?

Dunno Keith, its possible as the front and rear housings have the same bolt pattern but not sure whether the drive gear on the torque limiter shaft will line up with the chain drive when it's turned around. One day when I have a bit of spare time I will do the exercise and find out for you.[bigsmile]

Thanks Brian. I could do it myself if I get around to it. Just thought someone might have already.
See you next weekend.

Will do mate, do you want any more tubes?

[123rover50]

No thanks Brian. You gave me enough last time to see me out.[smilebigeye]

I’m about to start preparing the secondhand one winch I bought for installation and want to strip the drum and PTO housing for cleaning and to ensure they are undamaged. I was wondering were the best place to obtain spare part, primarily gaskets and seals including those needed for the gearbox during installation might be. Any help and advice appreciated.

For gaskets, a Manila folder is what we used to use and or gasket eliminator.

For seals, your local bearing shop
