Facing reamer to resurface crush washer seal surfaces?
Posted: Thu Sep 25, 2014 8:45 pm
I changed all my driveline and hub fluids last week and discovered that all the crush washer sealing surfaces in the housings had been scored/scratched across the sealing surface by previous attempts to pry out the used copper crush washers. Some damage is pretty severe, though I was able to get them all sealed back up - so far...
Does anyone know of a facing reamer that could be used to restore the sealing surfaces in the cases? I was thinking of making something our of a spot facing cutter with a pilot that would screw into the M22x1.5 drain/fill plug holes. It would serve to center and square the cutter and also prevent chips from entering the gear cases. It would be hand driven to prevent too much material from being removed. My only impediment is not having access to a lathe.
How have you adapted to damaged seal washer surfaces?
