Hello fellow bikers!
I have been searching up and down in previous posts.
and I cannot find the bearing size for the lower/bottom end connecting rod bearing.
I had one fail this past summer, and while the weather is cold here in alberta , canada, it's time to re-build.
I now have a really good motor...at least on this one the output shaft is true.
Thats what killed the last one.
The motor, as far as I know is just a 66cc engine, from toys for boys in calgary, it has no numbers on it at all...sorry.
Any help deciphering this , is greatly appreciated.
Many thanks, and happy riding! (=
Steve

When I replaced my cross shaft bearings in my China girl, I simply took the bad bearings to a powersports shop and they matched them up.

Cheese head capitol
your not going to replace the bottom conrod bearings, if thats toast ether order a new crank or a new motor, no one makes the size needle bearing the lower conrod uses, its a china only size lol. but also to replace the lower bearings you have to press the crank apart, then try to press it back together 100% true.
