    60 PTO Clutch housing filling with Trans lube

    When I got my tractor it was leaking a bit from the PTO shaft. I drained all fluids and went to work on the resto. Having finished the motor I filled the trans with 80w-90. A couple of days ago I took the PTO cover off to replace the seal and trans lub started leaking out of the bearing. I cannot see any seal in the shop manual or parts book that would prevent trans lube from getting into the PTO clutch area altho the book calls for different lube in both housings. Any thoughts on this. I am currently baffled and really don't want to tear the whole thing apart unless I need to.

    The PTO housing is a different compartment than the transmission. I'm in the middle of overhauling mine at the moment, still collecting parts. The only part that goes between is the internal power shaft.

    Here you can see the rockshaft/PTO housing is removed off of my 60.

    Here's the front side of the rockshaft/PTO housing. You can see how the shaft connects.

    This is the PTO oil pump. It's inside the transmission cavity.

    The seal on the oil pump is probably the source of your leak. Could be the gasket on the oil pump too. Unfortunately the rockshaft/PTO housing must come off the tractor to repair this seal. The oil pump can then be removed to replace the seal and gasket.

    Jason,
    Thanks for the pics and the info. I suspected as much. The cherry picker is in the garage now and it will come off tomorrow evening.
    I just read the resto thread you are doing on yours, big project. And yep those brake springs are stout. Looks like your trans cavity took some real hard hits. Mine looked fine, the front half was the bugger, it was stuck big time. Lots of rust but I finally got the old pistons out and it did clean up with a .125 bore. The wheels wedges like yours took some effort. The pinions were rusted bad but with heat and lots of rust dissolver ( many different kinds) I finally got them to work. Will keep this going with what I find

    Well I have it off and the 350# chunk of iron setting on the floor of the garage. The pump is off and the seal/bearing out. Now the can of worms is beginning to come to life. It seems that on the early tractors the seal was the only part. The later ones had a bearing and a seal - here is where the worms come in. They also had a different pump housing and clutch drum/ shaft. I haven't been able - yet - to find a replacement part like my original. I will let you all know what my searching brings and what my final fix will be.

    I'm currently in the same boat. I'm looking for a new clutch drum shaft. Fairly rare.

    Jason,
    My tractor is an early one, serial 3000, and has the pump housing casting number of A4568R. It seems that the seal / bearing that has the National number of AA-524-TR is no longer available, at least that's what my net searches are indicating. My plan now is to fabricate a bronze bushing in place of that seal and use an available seal behind it to block the oil migration. I think this will be less brain damage (and pocket book damage) than trying to hunt down a donor tractor with a late model pump housing and shaft.

    60 PTO Clutch housing filling with Trans lube

    Do you have the old one removed? Perhaps you can try taking it to somewhere like Napa auto parts and see if they can cross-reference it. I've had good luck with a local bearing shop as well. Can you post a picture of it? My oil pump has a separate seal and bushing. Maybe you can upgrade?
