Rotational
Balancing
Crankshafts
with V configuration need
Bobweights fitted for Rotational Balancing.
The
Bobweights simulate a portion of Piston, Rings, Gudgeon
Pin, Circlips, Conrod, Conrod Bearing and Oil weight. |

Balancing
Pistons & Conrods
Pistons are balanced to match the lightest piston weight.
Conrods are end to end Balanced, the small ends and the
big ends are matched to the lightest weight.
These weights are then transferred to a balance sheet
and used to work out Bobweights. |

Conrod
Balancing
Removal
of weight from the Conrods and Pistons is critical.
The material should be removed from the Balance Pads
or a place that won’t Reduce the Strength.

Heavy
Metal Balancing
Balancing
with Mallory Metal is used mainly for Race Crankshafts
when converting them from external balance to internal
balance.
The other reason is when the stroke has been altered
and the counterweights don’t have enough material.
Mallory Metal weighs twice the weight of steel.
