I am planning to change the oil in the rear axle of my 75B.

Does anyone know the size of key required to open the drain and filler plugs?

Thanks Brian
 
Ummm, it was a special tool. It looks like a 1/2" drive, but it's tapered. I took and old 1/2 drive and filed it down on my bench grinder. My word of advice is once you get them out, replace with a new plug you can get at an autopart store. My second word of advice is make sure you get the filler plug out first. You don't want to let the oil out, then find out you can get more oil in because the filler plug is stuck!
 
When I said special tool, I meant a British Leyland special tool. So I don't think you can pick one up at a parts store, tho' I have heard some very old US cars also had a similar tapered fitting.
 
The rear axle drain plug uses a 7/16 inch square drive. I made one out of 7/16 square stock I got at the hardware store for $1.00 and a old 7/16 socket that was cracked. Inserted the square stock with some glue and a hammer. Works great.
 
I always just stuck the rachet (without a socket) directly into the hole or used an extention like Stewart. worked flawless, even with the ball never gave me any problems
 
Used a 1/2 drive but it didn't fit flawlessly. Keep a bunch of pressure on the drive and hope its not frozen in place. Mine came out but not without lifting an eyebrow as to the fit of the drive extension. After reading the above, finding a cheap extension and grinding it with a taper for a perfect fit would be the best advice. Label it and you've got a nice $3.00 specialize tool to offer to your buddy!
 
I found that my Craftsman impact wrench fit it nicely and made the removal easy /ubbthreads/images/graemlins/laugh.gif

Just reduce the outlet air to 40 PSI to avoid damaging it! /ubbthreads/images/graemlins/nonono.gif

Well I could not find any 7/16 key stock so I bought a 1/2"
drive and bought a bench grinder. Mission accomplished and I have a grinder in the workshop.

Thanks everyone
Brian
