Kevin;

The fit of the outer race to the housing is 0.0005 tight to 0.0015 loose. Given that a loose fit was considered acceptable I would first slide the outer race into the housing and evaluate the amount of ‘slop’. If you have a narrow set of feeler gauges and you can slide a 0.002 gauge into the space between the race and housing then placing the described punch marks in the housing would be warranted. If there is zero galling and the race condition is more of a ‘frosting’ then I would not ‘knurl’ the housing. I would not use a Locktite product near an unsealed bearing, nor would I be aggressive in producing a tight fit. The intent is to allow the race to slide and abut the backing plate during the clearance checking procedure.

This subject of race/housing clearance appears on page 4 of the service manual supplement I attached to one of my previous posts. I’ll add some guidance on requalifying the bearing bore if the clearance is found to be excessive.
