auto 65 breather question

hi there,
in reading another post regarding the rear diff, the poster was reminded to make sure that the breather was clear and not blocked because he was experiencing some weeping from the shaft joints (seals?).
My BW auto 65 is leaking each side from the shafts that enter the main body of the box.
Q: does the auto box have a breather of sorts, and if it has, and was blocked, .....would this aggravate the leakage problem that I am having? me thinks this is a HarveyP6 question?

The BW65 does have a breather pipe, it has a push in fitting that fits into a hole in the RHS of the main casing, then travels up to about the same height as the top of the dipstick tube, and then back downwards to finish somewhere around the maincase/tailshaft housing join. Blow through it to make sure it's clear. If it is blocked it will make the box prone to leaks.
 
hi there,
thanks for the info Harvey, had a look and test on one car that is on the hoist , waiting for new front caliper pistons from UK, and after prizing the pipe connection out of the gearbox , blew through it , all was clear.
Its a difficult spot to reach and had to resort to long nose curved pliers to reach the connection. When finished, I looked like an IRA terrorist, black lips, trying to blow up a car....now to the other one that has the real leaks,ho hum

Maybe I should have said, make sure the breather pipe is attached to the gearbox fitting, then find the rear end of the tube and blow through it from there to make sure it's clear.....

You obviously like to make things hard for yourself. You're lucky to get the fitting back into the box, especially in-situ.

I did try blowing through the pipe with it still attached to the gearbox fitting, but there was no response to blowing because I was trying to blow air into a sealed container, so I then tried to remove the plastic pipe.
it was black plastic that had hardened with age and was very firmly fixed to the gearbox fitting.
In using the long nose curve pliers to remove the pipe, the gearbox fitting just came out unintentionally...
I noticed that it had 2 forked tangs on the inside that held it into the gearbox, and yes it was a struggle to get it back in.
In thinking about your warning, I note that the hooked tangs were made of hard black plastic as well and if one of them had broken off and vanished into the depths of the gearbox, it might have been game over and gearbox OUT.
I will be extra cautious when checking "Nelson" the other car that has the real gearbox leak problem.
Thanks again Harvey for your help in pointing out these possible dangers when working on this BW65...

Errrr.....You should have just pulled the dipstick out.....
 
hi there,
would blowing allow enough air to go through all the oil seals before it gets to the engine area and then relieve the pressure in the gearbox?

I'm not quite sure what you're getting at there, but if you can blow through the breather pipe, then it's clear, and won't cause any problems.
