Re: REME magneto oil seal holder modification - BSA M20

Hi John...I've got one that was removed (rather roughly) from some crank cases and as such it is no longer serviceable...However, it would work OK as a pattern for remanufacture...

The problem is that when the cases are badly worn you'll have difficulty picking up the exact centre of the hole prior to machining the case out to accept the modification plate...

I made a jig for that job. Alternatively, you could bolt the magneto in place and pick up on the end of the armature with a clock gauge to find the correct position...
It is often the case that the hole in the original aluminium boss inside the cases, if not too badly worn, can be machined out oversize for a larger O.D. seal, or machined oversize and an aluminium sleeve fitted to accept a standard size seal...
I've done them both ways in the past...Ian

Thanks Henk

This is similar to the REME version

I need to send the additional photos to Ian & photos of the magneto base so he can make an evaluation -

I hope the casings can be made serviceable again
