Disassembly of the re 1956 piston & conrod assy.

Hello coxaddict,

Thanks for your reply and greetings.
Reason to take assembly apart is the excessive end float of the conrod. I'd estimate that to be about 0.025". I usually set up the swaged type to have no detectable end float but the rod can swivel freely in the piston.
Thanks for the offer of a pre 1956 piston and conrod assembly, but as the piston is an excellent fit in the cylinder and conrod on the crankpin I plan to repair the assembly.

All my engines have to run and be in a fully serviceable condition.

I make any part for any model aero engine so plan to make a new slotted cup piece. Current thinking is from hardened and tempered steel.
Did occur to me lying in bed at 3 am unable to sleep that I could set the piston up in the Milling machine set to highest revs. and using a small diamond bit grind the middle of the wire circlip to "break its back" then prise out the ends with something like a dental pick. Would need to make a soft collet to hold the piston and some wire puller to hold the conrod to one side. Was hoping others had already devised an easier fix!
