I was reading a 1991 edition of The Bulletin and came across this, reproduced from The Austin Magazine of January 1932. As I have just this issue to deal with I wonder if anyone can shed light on the 'larger nut'?
Question: I find that there is a slight tendency - nothing to worry about in particular - for oil to penetrate from the back axle casing through the hub onto the lining on one of the rear brakes of my 1930 Austin Seven. Though only slight, as I say, I am afraid that this leakage may develop and prevent the brake from acting with its normal efficiency.I have reduced the replenishments of lubricant for the axle, but the oil still seems to get through. Is there any means I can adopt of overcoming this trouble without dismantling the hub or draining the axle?
Answer: Our Service Department can supply a special nut that is designed to act as a further means of stopping any oil that may pass the oil retaining washer in the Austin Seven rear hub. This nut is of a larger size than the axle nut formerly fitted as standard, and when tightened home, makes an oil tight seal with the end face of the hub. By fitting one of these axle nuts in place of that now used on your car, you will no doubt be able to overcome the trouble. When you have tightened this nut home, do not forget to secure it with the split pin.
