ford 601 workmaster brake shaft question

Smokey0150 · Apr 9, 2022

Guys, I need a little help. I am working on my 1960 601 work master. I am replacing the bushing on the left brake cross shaft where it joins
the transaxle(trumpet) The bushing part number shows it to be 78-2477. I have already gotten the old one out, but I don't understand what
keeps the fluid in the transaxle because the bushing is hollow. Am i missing something here? I don't see any type of seal in the parts
manual...nor was there one in the cavity when i pulled the old bushing out. Any help would be appreciated.

It's unclear to me whether you are referencing a cross shaft thru the bell housing area or the cross shaft on the later models thru the rear axle, underneath the tractor.

Either way, there are no seals involved because the cross shaft does not pass thru any fluid filled reservoirs.

The cross shaft i am referring to is from the left brake. It attaches to the parking brake pawl and is supported in a bushing pocket located
in the transaxle or trumpet. The one I am referring to is NOT the one underneath the tractor. It is the left brake cross shaft that goes
directly into the brake drum on one end and is supported by the transaxle on the other end. I didn't think the shaft should go into a oil
cavity but when i removed the bushing, rear 90 weight oil started coming out of the hole. I suspected the rear end oil level was higher than
the hole but I'm not convinced this is correct. I'm sort of stumped and not sure if I should put some sealant around the end of the bushing
because i can clearly see a small gap where it is open into the rear transaxle. I drained the rear end oil to stop the leaking but I'm not
sure what was causing the oil to come out. Any ideas?

Your rear axle housing has been compromised at some point. That hole should be blind and not open to the lubricant reservoir. Not sure how that happens.

A good clean-up and clean out and some J-B Weld might be your most reasonable option at this point.

Was it leaking before you took it apart and replaced the bushing? The shafts I've removed (albeit on 9XX series) have ball like ends which fit into the bushing and certainly wouldn't slow down differential fluid very much.

I don't have a very good picture...

ok....that would explain it. You are correct on the ball and the socket........and no....it wasn't leaking until i dug out all the rust and
debris inside the hole. I agree, the ball certainly couldnt stop any fluid flow.....and I jsut could understand what was going on. I
appreciate the help with the issue, maybe i can return the favor someday or pass on what i have learned to someone else.

Just a quick update to my question from a few days ago. I appreciate the reply and help from everyone...an update on my leaking rear brake shaft question. As it turns out, the left brake shaft ball and socket fits into the trumpet which is in fact open to the rear end cavity and can leak oil out of the socket. I thought the hole was a blind pocket but it seems it has a freeze plug driven in to stop the oil leakage. You can read the comments earlier about the issue I had. I have found out that the where the ball of the brake shaft is supported by a bushing.....which was common knowledge. What i didn't know was that the cavity is sealed by a expansion plug which keeps the oil into the rear end. I think it is a 1 1/4 plug, a freeze plug driven into the same hole that the bushing fits into. You have to remove the trumpet to repair the plug. Just a quick fyi for anyone else experiencing the same problem.
