I need a piston ring because im stupid and broke one putting the piston pin in. The piston # is AM53056 and I need a ring that will fit it.

I found pistons and rings for my 1972 jd500 through my local dealer who found them at www.parts-unlimited.com. Partsunlimited was the only place that my local dealer could find pistons for my sled so maybe they have yours also.

engine in this is 340/5 which has bigger pistons than the 340/22 if your totally stuck and cant find a ring i have a guy who can cut a new one for you. stock piston is two rings of same type.. aftermarket is two rings one is lring ... wiesco can come any way they want from tiny chrome to ll ring along or even polaris style rings.

340 rotax 0.020 over may also fit

ccw 340/5 also used in mercury raider scorpion and one rupp

If interested in used, I have rings, pistons and cylinders from a 72 400

it had about 100psi comp both cylinders but I think the 73 is different
