PTO Outer bearing Wipeout - Repair

[Lost Pup 187]

During this years snow cleanup , my PTO on the loader 418C just self destructed. Put the bell into my lathe and cleaned out the debris a bit. The bearing shell finally released. 
Parts arrive from RockAuto. I did have a Koyo bearing to compair to the Timkin. Both appear to be quality items.
Don’t forget to search the web for their rock auto 5% off coupon.
Some parts cleanup and install the new Timken outer bearing and the SKF inner grease seal. Back in action.

That bearing shell race was frozen solid in place. The lathe and a carbide tool and a few red hot shower curls and it released. You can see the curl nest in the pic above. I flushed the inner bearing with allot of brake clean and air nozzle to clean it out. 
 

The PTO pin itself pressed inward and was rubbing again the outer edge of the nose on the bell when it failed.

Did you also dress the friction surface, as it is quite pitted?

The pic shows after I dressed it. It was really bad before. Before I remove material on the lathe I want it see how it performs. I can skim it up on the lathe if needed. 
I picked up an extra PTO at the last show. Ready in the wings.

It appears that the outer snap ring groove is no longer there, please tell me I am wrong.

I was thinking the same thing......seeing that alot these days.

I've got a cone clutch bell from my C-195 that the nose is worn past the C clip groove.  Been thinking about how to fix it.  Maybe machine the end flat, then drill & tap for a cap with the C clip groove?

‘The retaining snap ring groove is intact. I will snap a pic when I quick paint the parts.  I did face the nose a small bit when I cleaned it up on the lathe.

The center bearing slowly gave out over time until the PTO pin slowly bent inward in use as the bearing collapsed. 

This dumb operator on the loader ( me) just kept tightened the PTO arm up and continuing to work but the PTO pin pin bent so as to be cut off .

Could be the case of too good a quality bearing. I use a $4.00 PP204RR6 Napa bearing. When it fails it usually starts to smoke or stink or both. I keep a spare PTO bell on the shelf and swap it out and keep going. Then I fix the bad one as the spare. This keeps damage to a minimum. I think I have changed 2 bearings in 15 years.

The loader FEL is always on so I gave the Timken a try. Have a rebuilt spare now as well.

@Lost Pup  interesting  related failures , agree with the  outer  , rock auto   sealed bearing , the inner  needle bearing  needs a  very high temp  grease  , typical  black , dry  , caking  is  telling you  of  needle bearing  lube breakdown , lucas , x tra hd , green chassis grease flash point  550 deg , also polyurea rated , minimal ammount  , to prevent  clutch face  contact , spot the OTHER  PROBLEM REFERAL ?  mule drive belt  fraying ?  those bearings are  easily , side grease shield , removed , cleaned out  , repacked with the same lucas 550 deg  green chassis , every  bearing in  my pto driven anything  , was changed over years ago  , no noise , no belt scream  , COLLECTIVE  ROTATIONAL  DRAG , is eating  your set up alive , all my deck spindles , spin by hand on the  mule belt area , no  belt fraying . thats a gold mine , upgrade spot  , detail every stage , also correct the sloppy   pto, lever start  , battery tray  frame , 3 horses with this , change , never came back ,  looking right at you  , pete

A few years ago I bought two used cones online, both were worn to the groove.  The guy then sent me two good ones.  Like 8ntruck, I might try to fix them as spares but there isn't much meat with the tapered ends.  I often wondered how those things got wasted, now Lost Pup explained how he did it.

Maybe not using a retaining ring and just make the cap fit is the answer?

Maybe build up weld to replace the worn area and machine it up in the lathe.

Not sure but it could have been the OEM bearing that got wasted. The grease on the inner bearing was just fine.

That cone is cast and not a good candidate for welding.

Tig braze maybe ?

Tig not so good, some chance that brazing will work.  What really would fix the problem is a trash can.

Tried fixing some trashed PTO pulleys, ending up in the scrap......
