Crank and Piston Question/quotes please

[IROOST1]

I bought a shee in peices and got ripped off in many ways. I just finally went into the motor to check it out. It has oversized carbs and a cool head with med compression domes. He said the top end was fresh and it wasnt too bad when i took it apart but i cant figure whats up with the crank and pistons. They look nothing like the other pistons from a stock shee i just rebuilt. The pistons are wiseco i think, but the #'s are A62D0 and the other one is A62E0? Does anyone know what size they are? And the rods say hot rods and the # ck 121 is stamped on the side. Are they stock length?

 

The crank doesnt feel right. I can feel the bearings as i hand turn the crank. It kind of jumps from one bearing to the next(as best i can describe it) What should i do? Should i just put a stock low hour crank in if its stock length rods? Or should i have new bearings put in the hot rod crank.

 

Also, what would it cost me to have new bearings put in and have it welded? And where can i have it done around northern illinois?

 

Please Help!!!

OK, heres more #'s for you all. 9439 on both then 65 on both, but the last #'s change. One says 43MM and the other says 42MM. It beats the hell out of me why they did that. Also, i cant find those #'s anywhere online.

Sounds like it might be a stock stroke, stock length rod hotrods crank with two different sized pistons. Take a caliper and check the bore of both and see if its the same. If you are going to get a new crank or have that one rebuilt you should go with a TZ bearing on the clutch side. Talk to some of the builders on here and they can get you set up with what you need. Or check out ebay. I wouldn't run that crank if it feels sloopy or bumpy at all. Split the cases and take the crank out and see what you really have.

Thats what i fugured. I will take it out once i get done rebuilding my 01. (seems like bearings go out a lot on the shee's). But why in the world can i find these pistons in the wiseco book or online and why would one say 43mm and one say 42mm????? But the bore is the same. I guess ill just take out the crank and leave the top end alone.

I figured it out, i emailed everywhere and got my answers. The crank is a standard hot rods crank. and the pistons are custom vitos power pistons. Thank god for great customer service or i would have never figured it out.

crank rods can move side to side, its when they move up and down on the crank you have a problem. midwest crank in green bay wi does awsome work. email me if you would like his #. aaron

 

as i re-reed your post you said it jumps from bearing to bearing, ill bet your crank is bent.

I dont think it is bent, the engine was supposedly running fine, its just when i pulled it apart, it had some dirt and crap down the one side crank. I think the one bearing just grinded the shit out of the balls and now its crapped out. Thanks
