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’t locate the breather because there wasn’t 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’t fit – 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” bolt but too large for ¼”. Also, the 5/16” bolt fits just within the inner diameter of Moss part 267-040.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>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? <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>David Councill<o:p></o:p></p><p class=MsoNormal>64 B<o:p></o:p></p><p class=MsoNormal>67 BGT<o:p></o:p></p><p class=MsoNormal>72 B<o:p></o:p></p></div></body></html>
