oil leak on A belt pulley

Charlie M · Jun 9, 2012

I changed all the seals this spring on the rear end of my A and the only place that still leaks is the belt pulley. I put a new seal there but there is a tube that goes over the shaft and through the seal - what keeps the oil from leaking between the shaft and the tube. I didn't see any kind of seal for that nor do I see anything in the parts book.

I cleaned the shaft & put small amount of silicone between the spacer and the pulley on the shaft to stop the oil, worked great, stumper

You dont use it so drain it then it wont leak.

I suspect that the end of that tube seals against the bearing when you tighten the bolt that holds the pully on. However, I replaced that tube and mine still leaks, even with a new seal. Draining the belt pully housing is only a temporary cure as lube is pumped into there by the oil slinger gear.

I do plan to use it. I've got a corn sheller that tractor will work great on and I may ted hay with also and use the PTO. Its a working tractor but I still don't want oil leaking all over the place.

When it gets lube again drain. Depending on use it would take some time to get full again. You could put some silicon there is it wouldnt be used. Some leak more than others with new seals some dont even leak.

First question is are you sure you don't have too much oil in the trans. They don't take much, and it's easy to over fill them.

Pull the level plug near the left brake connection and make sure none comes out.

If the level's ok - I'm not 100% sure - but I believe there's an inernal "weep hole" of sorts in the housing that allows the gear oil to flow through and not accumulate.

Even though it wasn't that long ago that I rebuilt mine - for the life of me I can't remember exactly where it was, or what I'm thinking about! - I just remember being surprised to find a hole somewhere in there that was plugged with sludge.

I'd pull the drive off, clean it all out with kerosene, and check things out - or perhaps somebody here with a better memory can clarify - I could be way off.

The housing comes over very easily - just be sure to retain the thin spacers if there are any - (sort of like thin metal gaskets).
