Reply To: Somerset differential breather

[number5]

Hi Malcolm,
On A70 and 90’s, atop the breather there is a screw driver slot, and using a wide but stubby driver, they screw out. I think they are either 5/16 or 3/8 inch BSF.

If that fails, there may be enough room to use a pair of multi-grips on the stem. Just be careful, for I know that at some time around late 53/54, A70 Herefords had plastic ones fitted, and they can break quite easily.
