Ford 4000 pto leaking-Question's

[Rdiel]

I have a 1967 Ford 4000 3cyl diesel tractor with 540 independent pto that is leaking profusely out the pto shaft in the back. I read where the shaft is held in position by a snap ring and it can come off causing the shaft to slip back and tear the seal. Has anyone had this problem and what is the fix? I hear you must split the tractor to fix?

I repaired that same thing on a friend's 4000. Just removed the plate from around the PTO shaft to make the repair. If I remember right the snap ring went on the shaft and when it was pushed in it snapped into the groove on the tractor. The only other thing was to replace the seal in the cover plate. The only problem I can think of with this is the pieces of the snapring that proke off are still in the tractor somewhere. That hasn't caused a problem yet though. Pretty simple fix really. I think the parts were $20 or so.

There are a few folks on here with way more experience than me with this particular tractor that will be able to correct me if I am wrong.

Thanks rasimmo I hope it's that easy on mine, I haven't had the chance to tear into it yet. Thanks for the reply.

i believe if you pull the pto shaft on a twin stick 4000 w/ ind pto.. you may drop a thrust washer requiring a greased up broomstick to reset.. though rickb or whodat are much more familiar with the 65+ machines than I am.

You are correct Soundguy. I haven't had to do it but have read several times about guys having to grease the washer up and reinsert it with a broom stick. If you don't get it right it means a rear split and or the top cover has to come off.
Best to read the manual carefully before starting the job.

i understand the twin stick 3000/2000 is a lil more forgiving and you can open the inspection cover and move the coupler that dops if the pto is not slid to engage too.

lots fun things to watch out for on the 65+ machiens.


UD.. I near forgot you were here at TBN. gonna have to remember that and add your name to the 65+ guru's. I try to stick the to 4cyl jobs..

Soundguy,
Thanks.
The 2/3000s are pretty much a different animal where the pto is concerned. With or without Lpto they are not much different than an 8N, 00, 01, etc in the way the sliding coupler engages the pto shaft to the back end of the tranny.
4/5/7000, etc is a different animal with the hyd pump in the rear end and pto driven through a clutch pack off of that.

Hey you all got it fixed, done it all from the back! Snap ring came off on the inby side of the bearing and let the shaft walk out and the outby snap ring ate the seal up. It was an easy fix, but there is a washer in the clutch pack that will fall and just cover the hole with the top side of the washer. I just put a little grease on the end of the shaft when going back together. Pushed and turned the shaft against the washer and it went right on in (like it had eyes! glad it did cause your doing everything by feel at that moment) anyway not bad, I gave it a #3. I bought a service manual on CD off of ebay for $10.89 (including shipping) it is very good you can print any page you want and you don't have to worry about getting your greasy finger prints all over it and stuff, it was most certainly helpful I would strongly recommend getting a manual. My only Question is what cause it to do this, The snap ring was bent like something pulled really hard on the shaft. I just had a finish mower on the tractor at the time and the shaft on in works in and out easily and has plenty of movement. After I got everything back together I went out and mowed some and watched everything and the shaft moves in and out a little just from the bouncing of the mower itself. Could this cause that to happen you think?

PS. Cost me $29.00 for two new snap rings, a seal, and a new gasket for the cover. The bearing was good.
And thank you very much for all the info...........and sorry for posting this twice (here and the repair forum) kind of new to the forum thing!!

keep an eye on it.. sometimes when the snap rings pop out of the groove in the bearing carrier, they round a lip and thrust force can pop them out agian.

just check it from time to time. may be fixed for good if you are lucky.
