Big gear ring bull gear
The pinion and bull gear are made from similar material to the crankshaft and with a high precision double helical gear, with less back lash than any of our competitors. The precision gears ensure power is transmitted over the full width of adjacent gears and the decreased backlash prevents the hammering effect, which pccurs with speed change.
