Wrist Pin Bearing
Hi guys,
Need answers quick. I'm rebuilding the top end in my bike after it siezed last weekend (ring pin failed, ring rotated and then got caught in the exhaust port....ouch). I forgot to order a new wrist pin bearing to install, so I need to know (1) how much play is acceptable in this bearing and (2) will a Honda CR250 wrist pin bearing fit (which year?)? Let me know ASAP. Thanks, Steve |

Reuse the bearing.
They really don't wear out. |

Seriously? It feels really sloppy in the little end of the rod.

It will if the wrist pin is not inserted as well, as the needles move in the cage slightly.

Figured that out. Once I put the wrist pin in, everything was nice and smooth.

haha. dad tried to tell me that my new wrist pin bearing was worn out as it had movement when it wasnt running on anything... doh, it needs to be between the pin and the rod to measure the play. the one i replaced looked brand new if not a bit blackened. no play at all
