And the rod looks about 2 or 3 Thou bigger. when you put it on the Pin and move it around.
Also have a look at the Part that snaped off on the crank its all smooth.
OK!send the crank and conrod to me. I will send new parts to you. I just want to know if the engine problem is not due to mis-use or abuse.
I have told with my boss. He agreed that if the play is not too big between broken crankpin and conrod bushing,we change new parts to you. That is what I can do now.
