I am working on the rear axle of a 64 MGB. After a routine check of the =
car,
I had noticed a small oil leak from the oil seals on both sides which =
lead
me to suspect pressure buildup due to a plugged breather. First sign of
trouble was that I couldn=92t locate the breather because there wasn=92t =
one
with the hole buried under an oil/dirt buildup. I cleaned off the sludge =
and
located the breather hole and cleaned it out as best possible with the =
axle
in the car. Then I went to install Moss part 267-040 rear axle breather =
but
it wouldn=92t fit =96 too large. A check of Moss catalog shows it to be =
the
correct part for both banjo and Salisbury axles. The hole is threaded =
but
too small for a 5/16=94 bolt but too large for =BC=94. Also, the 5/16=94 =
bolt fits
just within the inner diameter of Moss part 267-040.

I happen to have a couple of spare banjo rear axles so I checked them =
and
both of them have the larger holes and the Moss part fits. However, they =
are
also wire wheel banjo axles whereas the one on the 64B is for disc =
wheels.
Does anyone have an idea what thread size this early banjo axle might be
using? Or suggestions on how I can establish a vent with another part of
some kind?=20
