MG TD TF 1500 - TF Rear Axle Bearing

It appears that new rear brake cylinders and shoes were installed not to long ago. I noticed that the shoes had a slight film of oil on them and checked the axle seal for wear. The seal appears to be new also and not leaking. My question; Is there supposed to be a gasket between the bearing retainer and the housing as it looks like the surface between the two and around the bolts is damp with oil. PJ

Nope, just a thin film of your favorite sealer. Bud

Thanks Bud, I usually use High Tack sealers for regular gaskets. I think they have a gasket material in a tube which is microscopic thin when everything is tightened up. There was no indication that anything like that was applied before. Could be the reason for a light oil seepage around the bolt heads and in turn working it's way to the brake shoes. Don't know what the other side looks like yet. PJ

Years ago I had a chronic rear drum oil leak. I eventually figured out it was somehow leaking between the inner bearing face, the axle shaft, and the tapered collar and then into the drum. Since then I always clean all oil off of the mating parts of those pieces and use a very, very thin film of blue Permatex and no more leaks. My leakage problem may also have been due to worn splines and a drum that wouldn't stay tight. Also- if the big hub nut is loose then it will leak a lot. Make sure the surface of the split collar that the seal rides on is perfect without any scratches or grooves.

Will check George! I never put anything back together without completely cleaning everything. Thanks!
What's the torque numbers in foot lbs on the axle nut? PJ

It's 150 ft.lbs and then to the next cotter pin slot. I shave the spacer until 150 will do the job at a cotter pin slot, because I'm not superman.

Thanks Dave! PJ

You can replace the bearing with a sealed type. I finally had to do that and now the leak is gone. Check the bbs or archive for info on this.

I think the parts just wear out and the tolerances aren't what they should be.

i had minor corrosion and pitting on the face of the tapered sleeve the seal runs on. so small i did not see it on first go around. found it out after replacing the seal the first time. regards, tom

If this problem comes back, which I hope it won't, I'll take Larry's suggestion and replace the bearings with sealed ones. PJ
