How can i tell if the thrust washers in my engine are oversize or not? Are they stamped like the bearing shells?
Thanks,
YG

Good question - 'don't know' is my answer! But unlikely to be oversize in an unmolested engine. Mike them and compare I suppose is the way forward.

Why would they be oversized? Crank regrind means oversize, but they grind the journels not the thrust section

Oh yes they do - if there is any damage there they will take a light skim off the thrust faces on the centre main.

I think you will find the o/s stamped on them, and I believe the next size is plus .003''

Yer if they are oversize its stamped on the back... the ones I put in my engine said "STD"

I thought that a crank regrind took the thrust faces out as well - so a .010 regrind would increase the 'gap' by .010 ?

I have just measured my old MM centre main (-020) and it would appear that the 'gap' does not increase with a regrind.
Surely it should because the thrust face must wear?

Only if the thrust faces needed to be reground.

They won't touch the thrust faces unless it's necessary!
