Scratched bearing...ur thoughts
i took apart my block crank and mains yeasterday (jdm b16a 2gen) and found the following
there on 3 of the main bearings when you pass your nail over it you can feel the grooves im pretty sure im going to have to change these but i checked the crank and there doesnt seem to be any scrathes on it the rod bearings are fine thoughts http://img422.imageshack.us/img422/2560/bearings9ii.jpg |
Re: Scratched bearing...ur thoughts
that's a good sign, the bearings did what they're supposed to do. Looks like a metal shaving or something got in there and the bearings flow over it so they don't dig into the rod (or crank). So you obviously need new bearings, but they did their job in protecting the other surfaces :y

Grab yourself a new set of bearings. And thank Mr Babbit for the mulit layer bearings we have these days with great inbedability.

Maybe someone switched the stock crank out, and those were the bearings that gave the correct clearance?
