Stud remover-what sizes?
 

I am going to get the snap on collet tool, and wanted to know all the sizes I should get for use on the 911 engines.

M-6
M-8
M-10

Any other sizes I should get too?

Donnie, you need the thread pitch in addition to the size.

M6x1.0 should cover the sump screen, chainbox cover, thermostat, breather cover, intermediate shaft cover, etc.

M8x1.25, this is most of the case studs

M10x1.5, headstuds and the larger case studs.

There are no other sizes in the engine.

Thanks John. BTW it was a bad tach, replaced it and all is good.
