    SEM903A
  2. 3
    Calculate connecting rod bushing clearance. Connecting rod bushing clearance = C - Dp
    Standard: 0.005 - 0.017 mm (0.0002 - 0.0007 in)
    Limit: 0.023 mm (0.0009 in)
    If it exceeds the limit, replace connecting rod assembly or connecting rod bushing and/or piston set with pin.

  2. 2
    After driving in small end bushing, ream the bushing so that clearance between connecting rod bushing and piston pin is the specified value.
    Clearance between connecting rod bushing and piston pin: 0.005 - 0.017 mm (0.0002 - 0.0007 in)

FLYWHEEL RUNOUT

Runout (Total indicator reading)
Less than 0.10mm (0.0039 in)
