Can this engine be repaired?

[Kurt in NJ]

To further complicate there are 2 different centerlock rings --page 366 of the service bulletins--
A-6140-A ---0.115-.116 wide
A-6140-BR ---0.126 -.127 wide

i have 2 sets of aftermarket wrist pins, both sets don't have the groove as deep as original pins

I have several sets of new pistons that use the centerlock pins, havn't found the clips or good pins, the piston bosses are the same width and thickness as the end clip type, I figure that I can chuck a wristpin in the lathe and with a radius ground cutter make the groove for the later clips

one of the engines that showed up on my doorstep looked worse than your engine and the bore cleaned up at .040 ---instead of a sleeve and trying to use your existing pistons perhaps a new set of pistons would be a better solution
