F15A WIP - some questions

[Hanno Spoelstra]

Finally got round to do some work on my F15A today.

Q1) Left rear brake back plate: should I take it off or is this stage of dismantling far enough?

After I took this pic I took the wheel brake cylinder off, it will be replaced by a new one. Bearing race is still good, edge of seal race seems to have a burr which needs smoothing.

Q2) Which one is better? The leather or rubber seal?

Thanks,
Hanno

P.S.: sorry for the quality of the pictures (cell phone thingy).

Left hand axle shaft.

Beautiful condition, except for some unevenness where the inner axle oil seal sits?

Hopefully will smooth out with polishing as well.

Hi Hanno

Good to see you getting your hands dirty!

I wouldn't take the backing plate off unless there is a good reason to do it.
Also I'd think the Rawhide seals would not be as effective as modern ones.
Did you have the special hub nut socket or did you use a hammer and cold chisel in the manner of many mechanics before you?

Yes, I should do it more often. . .

Thanks for the tips! Yes, I did invest in the special 8-sided 3-inch socket (bought a NOS one from Dirk). Luckily no signs of chisels being used before.

If your inner seal has a CR number it is probably still available. On the C60S after the nut keeper excitement the inner seal was damaged on my truck but the part number was still readable on the seal. It was a stock seal 3 day delivery.

Cheers Phil

Phil,

Here's hoping I do not need to replace the inner axle oil seal (C01Q-4702-C) as I would have to dismantle and split the entire axle.

For the hub inner oil seal (BB-1175 C / GM-1798517) I have both a rubber and leather version to choose from.

Somewhere I read a leather seal will withstand surface irregularities better than the rubber type?
