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.

Cheers,

Bob Haskell

Bob is correct however a word of caution... be careful that in tightening t=
he #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.=20

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