1940 9N right side axle removed to fix the oiled brake situation.
We found 1 of the 6 hub studs was broken. It was the one on the bottom. This may have caused the whole issue.
We found what appears to be the seal kit installed that allows you to put grease in the bearing verses the normal oil flow but there was no grease in there, just some oil which I must assume was leaking by the bell shaped seal or from the lower area due to the broke stud. The bearing and race still appear to roll smoothly and feel unharmed.
We are deciding on whether or not to remove the pressed on bearing retainer so that the outer seal can be replaced. Thinking that maybe with a new bell shaped inner seal installed along with grease in the bearings that the outer seal would no longer be an issue and save us from the headache of removing the retainer. Input wanted here.
We are trying to think of the best way to remove the retainer without harming the bearing with meal debris, if we go that route. Input wanted here.
We also only found one paper gasket on each flange during the removal. I though that was kind of strange from what I've read here. I could see no damage to the axle end. Input wanted here.
When I got to the shop, Mark had already removed the the wheel and was in the process of removing the hub/brake and axle so I didn't get a feel for existing end play.
We removed the existing 2 gaskets and did a mock up assembly without new gaskets or bell seal just to see what the end play felt like. With 4 of the 6 bolts tightened down there was no end play but the assembly rolled smoothly. I guess we should have stuck several gaskets in for the mock up so we could have a better feel of what it is going to need for gaskets.
The brake shoes looked new but oil soaked. There were still machining marks on 90% of the shoes. I guess we will try using a heat gun to see if it will wick out some oil. Input wanted here.
