Took the head off and removed the pistons. The upper piston has wear between the wrist pin and the piston. The lower piston does not appear to have wear between the wrist pin and the piston. Both pistons have wear between the rod small end and the piston pin. (Both pistons are scored opposite the exhaust ports. But I don’t think this scoring is too bad.)
From the parts list for FD-10, I would need:
Piston and connecting rod assembly part 277203 quantity (2)
Piston rings (set of 3 rings) part 301787 quantity (2)
Alternately I could use:
Connecting rod assembly part 277205 quantity (2)
Piston and dowel pin assembly part 277402 quantity (2)
Piston pin Part 203238 quantity (2)
Piston rings (set of three rings) part 301787 quantity (2)
How do the piston pins (wrist pins) come out? Are they driven from a particular side? Should the piston be supported to prevent bending it?
Thank you,
