Can a crankshaft be balanced with a 2% bobweight?
Because of the tolerance (+/-2%) the crankshaft cannot be considered balanced. For instance, for a crankshaft listed as having a 1800 target bobweight. The actual range of bobweights one of those cranks might have is from 1764 (1800-2%) to 1836 (1800 +2%).
