Installing a used crank in my 2001 200 EFI Merc. Crank looks good but the oil pump drive gear seems to be loose on the crank. The gear teeth look unhurt. Mercury shop manual says not to replace gear unless it displays excessive looseness. Can anyone define "excessive looseness" for me? I can't compare to the original crank since the original owner discarded it after teardown. On older engines (late '80s) I routinely removed the oil injection systems due to a lack of trust. I would like to run the oiler on this engine but the looseness of the gear has me spooked, any thoughts?
