Hi Greg, I got 3 engines rebuilt, waiting for another front bearing for the
46. The wristpin in the 60 was broken in half when I removed it. I had an
X60 good used Wrist pin that I installed teflon pads in an installed it,
same diameter & length as V60. The X60 only has a hole on one end so I
placed a pad on the other end during assembly. Also I dis-assembled new G51
Chinese engine & found everything good except inner bottom rod bearing
wasn't counter sunk for clearance on crank pin so I counter sunk bearing &
replaced ring as well. I cleaned & lubed crank bearings & used them as they
are good. The bottom bearing on the other G51 was worn egg shaped. So when I
pressed old bushing out I discovered bearing hole in rod was egged as well.
I reamed it out slightly larger & made new bearing for it. It is good now
and not clicking when you turn engine over.I lapped all 4 liner tops, new 51
& 60 were not flat but are now. Bearing should be here tomorrow & will
finish 46 & mail engines. Do you want them in 2 packages? Take Care, Frank
