Selection
  1. Place the plastigauge axially along the balancer shaft journal as shown.
Special tool (a): 09900–22301 (plastigage (0.025 – 0.076 Mm)) Caution

never rotate the balancer shaft when a piece of plastigauge is installed.

  1. Mate the lower crankcase with the upper crankcase, and tighten the crankcase bolts (m8) and crankshaft journal bolts (m9) to the specified torque.
Tightening torque crankshaft journal bolt (m9): 18 N·m then turn in 50° crankcase bolt (m8) (initial): 15 N·m crankcase bolt (m8) (final): 26 N·m crankcase bolt (m6): 12 N·m

  1. Remove the lower crankcase and measure the width of the compressed plastigauge using the envelope scale. This measurement should be taken at the widest part of the compressed plastigauge. If the oil clearance exceeds the service limit, select the specified bearings from the bearing selection table.
Balancer shaft journal oil clearance standard: 0.028 – 0.052 Mm (0.0011 – 0.0020 In) service limit: 0.080 Mm (0.0031 In)
