Rod Caps, balance, weight confusion. Need help

Did your balancer machine the caps and rods at all?


You have to match the proper rod and cap that they were machined to. If you mix them, it can cause drag on the crank, or even make the crank so tight that it cannot turn from the mis-match.


On some rods and caps they chamfer the sides of the rod for the crank bore. If they are, sometimes you can look at the chamfer and match the chamfer on the cap to the rod from side to side. It's like doing a puzzle.


If there are no chamfers to help judge by, then you have to rely on the stamped numbers on the rod and cap from the factory.


ALWAYS KEEP THE MATING CAPS AND RODS/MAINS TOGETHER - NEVER MIX AND MATCH THEM.
