The bearings are .010 undersize, and CANNOT be used on a
standard crank. The 698 number is correct for the rods, but I
did not take more time to find the VP number for the mains.
Randall can answer better than I as far as changing bearings
without removing the crank, but I can't see why you would want
to. You would still want to measure the end play for the thrust
washers and check the timing chain, etc. It's just not that
hard a R&R job!
