CRANKSHAFT/TRANSMISSION 9-23
Crankshaft and Connecting Rods
Crankshaft Runout Inspection
• Measure   the crankshaft runout.
  If the measurement exceeds the service limit, replace the
  crankshaft.
  Crankshaft Runout
    Standard:     TIR 0.02 mm (0.0008 in.) or less
    Service Limit:   TIR 0.05 mm (0.0020 in.)

Crankshaft Main Bearing Insert/Journal Wear
Inspection
• Split the crankcase (see Crankcase Splitting(9-9)).
• Place a strip
  Cut  strips of plastigage (press gauge) to journal width.
• installed in theoncorrect
                      each journal parallel to the crankshaft
                            position.
• Tighten   the crankcase bolts to the specified torque (see
  Crankcase Assembly(9-10)).
                            NOTE
  ○Do not turn the crankshaft during clearance measure-
    ment.
  ○Journal clearance less than 0.025 mm (0.00098 in.) can
    not be measured by plastigage [A], however, using gen-
    uine parts maintains the minimum standard clearance.

• Split the crankcase again, measure each clearance be-
  tween the bearing insert and journal [B] using plastigage
  (press gauge).
  Crankshaft Main Bearing Insert/Journal Clearance
    Standard:      0.010  0.034 mm (0.0004  0.0013 in.)
    Service Limit:   0.06 mm (0.0024 in.)

  If the clearance is within the standard, no bearing replace-
  ment is required.
  If the clearance is between 0.035 mm (0.0014 in.) and the
  service limit (0.06 mm, 0.0024 in.), replace the bearing in-
  serts [A] with inserts painted blue [B]. Check insert/journal
  clearance with the plastigage. The clearance may exceed
  the standard slightly, but it must not be less than the min-
  imum in order to avoid bearing seizure.
  If the clearance exceeds the service limit, measure the
  diameter of the crankshaft main journal.
