• The balancer unit consists of two balancer shafts (No.1 and No.2) with weights, the balancer unit case and the adjust shim which adjusts the amount of backlash in the crankshaft.

• The two balancer shafts (No.1 and No.2) are driven by the drive gear which is attached to the crankshaft.

• The balancer unit cannot be disassembled because it is a precision unit.

• Replace the adjust shim to adjust backlash. There are 40 kinds of adjuster shim depending on the thickness. The adjuster shim can be determined by checking the engraved identification mark (2 digits) on it.
