The vent holes in the axles of T-series cars are protected by the stra=
p that secures brake line to the axle. It seems crude, but I can think o=
f no complaints about dirt in the axle tube. If you can not find the=
fitting that threads in, you might try covering the hole using a hose c=
lamp, perhaps with a piece of scotch-brite to provide a bit better air p=

Subject: [Mgs] banjo axle breather dilemma
Date: Sat, 11 Jul 2015 17:00:11 -0700
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 whi=
ch lead me to suspect pressure buildup due to a plugged breather. First =
sign of trouble was that I couldn’t locate the breather because th=
ere wasn’t one with the hole buried under an oil/dirt buildup. I c=
leaned off the sludge and located the breather hole and cleaned it out a=
s best possible with the axle in the car. Then I went to install Moss pa=
rt 267-040 rear axle breather but it wouldn’t fit – too larg=
e. A check of Moss catalog shows it to be the correct part for both banj=
o and Salisbury axles. The hole is threaded but too small for a 5/16&rdq=
uo; bolt but too large for =BC”. Also, the 5/16” bolt fits j=
ust within the inner diameter of Moss part 267-040.
=
I happen to have a couple of spare banjo rear axles so I checked them an=
d both of them have the larger holes and the Moss part fits. However, th=
ey are also wire wheel banjo axles whereas the one on the 64B is for dis=
c wheels. Does anyone have an idea what thread size this early banjo axl=
e might be using? Or suggestions on how I can establish a vent with anot=
her part of some kind?
