I've lurked here a long time but this is only my second post (suck at typing!) I have a very low hours 717 that had the retaining clip for the center crank gear (drives the rotory valve shaft) slip and allow the gear to hit the inner seal and damage it. the crank and bearings are excellent and I don't want to spring for a rebuilt crank over one seal. I am looking for a shop in the northeast (I'm in Albany NY) that will split the crank and install my seals. Any help would be appreciated,
