Balance Shaft

The cast iron balance shaft is mounted in the crankcase above and in-fine with the camshaft. A camshaft gear drives the gear attached to the balance shaft. The front end of the balance shaft is supported by a ball-type bearing. The rear end of the balance shaft uses a sleeve-type bearing.
