Anyways ended up getting it for free last night and tore it down.
All journals look great but #4 it took a beating for shur. The wrist pin is binded up pretty tight too but can move by hand. I guess something happened with the timing since a chunk of the head is missing on the front. The idler gear was completely stripped in the head due to poor assembly. So FAILIER due to contamination/lack lubrication #4.
After removing the pistons i can rotate crank by hand smooth as butter. So now for my questions about this crank*
1) how the heck do you measure a destroyed spun bearing journal little rough for a mic
2) anyone know the surface hardening process used (nitr/induct/tuf)?
3) ^this will give me idea of how much i can get it ground down safely
4) i read a few people getting some took off and re nitrating their crank???? some say thats bad idea?some its not needed
*nitraded crank is surface hardened .010-.030 .....chrome hardened??? anyways im lost heres a link to some crap bout it
