[Healeys] Swapping overdrive drain plugs

[michael.salter at gmail.com]

Bob is correct however a word of caution... be careful that in tightening the #62 the pump body does not turn. I would recommend a long piece of 10/32 thread in at least one hole to eliminate that possibility. 

If it does turn it is really hard to re align and the pump non return valve will not work...as in no overdrive.

Simon, The oil pump housing (#61) is press fit in the OD casing. Removing the two screws (#63) and washers (#64) to get a socket on the threaded plug (#62) shouldn't mess things up. See tool 18G183 in the workshop manual - it's what's used to remove the pump after removing parts #65 - 69.
