CRANKSHAFT/TRANSMISSION 9-23 Balancer

Balancer Removal

• Split the crankcase (see Crankcase Splitting).

• Pull the balancer shaft with the balancer gear out of the crankcase.

Balancer Installation

• Apply oil to the inside of the balancer shaft bearing insert.

• Align the timing mark [B] on the balancer gear [A] with the timing mark [B] on the balancer drive gear [C] of the crankshaft.

• Assemble the crankcase (see Crankcase Assembly).

Balancer Shaft Bearing Insert/Journal Clearance

• Measure the bearing insert/journal clearance using a plastigage.

OSplit the crankcase and wipe each bearing insert and jour­nal surface clean of oil.

OCut strips of plastigage to bearing insert width, and place a strip on each journal parallel to the balancer shaft so that the plastigage will be compressed between the journal and the bearing insert.

OInstall the lower crankcase half, and tighten the case bolts to the specified torque.

Torque - Crankcase 8 mm Bolts: 27 N-m (2.8 kgf-m, 20 ft-lb) Crankcase 6 mm Bolts: 12 N-m (1.2 kgf-m, 104 in-lb)
