Anyone ever rebuilt one before or would it be better to just get another? I ripped the end out of mine (tractor end) on a stump. Guess my slip clutch is froze up, no stump jumper. I always used a grade 5 bolt as a shear. I think the shaft was probably cracked from replacing them all these years, over tightening. Ripped the bolt in half too. |

| It sort of depends on where it's tore up. Is your stub-shaft in the gear box ok or is it bad? I did sort of a half rebuild on mine, putting a new collar on the long pto but leaving the stub shaft alone even though it's egged out. They told me that shaft is hardened and not to put any heat on via welding and fixing the hole by re-drilling it. Rltool in Michigan on this website machines a new collar so the old one was ground off by my machine shop and the new collar welded on. Only problem was the stub shaft was no longer round so it had to be machined to fit the new perfect collar. In my case this was a half fix but good enough to run a Woods bush hog. The other issue is the rear carrier bearing and I drilled a pin hole in the seal so I could use a needle zerk and shoot some grease in there and not do any further work on that bearing for now. This may not fit your situation but it worked for me, at least temporarily. |

On the tore up shaft I did drill and tap it for a grease zerk in the carrier bearing 20 years ago. It wasn't the stub shaft. I tore the collar up. I looked on craigslist after I posted this and found one for $25 15 miles away. I couldn't believe it. Just went and got it. Looks like it was never used. |

| Better fix your slip clutch or you will bust teeth off of the intermeddiate gear. |

I have reconditioned the short pto shaft out of the gear box also. You can take the shaft out of the housing. I drilled & reamed the wore out hole. Pressed a piece of stock into the new hole. Drilled & reamed that back out to original factory size. Then put the shaft in an OD grinder. Ground the fit area straight & round. I have some of the collar sleeves made with undersized bores. So I can custom fit it to the new diameter on the short shaft. I would advise against just welding up the old one. Due to, if not done properly it could make that end of the shaft brittle. Ray W. |

Already did that once about 10 or more years ago. Did while mowing a ditch. |

It's not supposed to be a shear bolt. It's supposed to be a special shouldered bolt. I've welded on new collars a couple times. AGCO used to sell that part. The last one I did was about 15 or 20 years ago. I gave the machinist a new AGCO one to use as a pattern cause I figured I'd need to do more than a couple over time. I wonder where I ever put it?  ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

Looked around online for another shaft. Roughly around $200 for a new one without the bearing and $150 used with a bearing. Looked on craigslist last Saturday morning and only one came up about 15 miles away for $25. Don't think I ever got to town that quick before. Barely any wear on it. Haven't hooked up the mower yet to see if I ate the PTO gear or not. The seal is leaking though. No excessive end play on the stub shaft. Anyone have the part # for the proper one. I remember it's like a double seal and not a single lip seal that I know don't work well. |
