CRANKSHAFT JOURNAL BEARING
INSPECTION
• Inspect each bearing of upper and lower crankcases for any
damage.
SELECTION
• Place the plastigauge axially along the crankshaft journal,
avoiding the oil hole, as shown.
09900-22301: Plastigauge
• Mate the lower crankcase with the upper crankcase.
• Tighten the crankshaft journal bolts (M9) in ascending order
of numbers assigned to these bolts. Tighten each bolt a little
at a time to equalize the pressure.
Crankshaft journal bolt: (M9)
Initial : 18 N·m (1.8 kgf-m, 13.0 lb-ft)
Final : 50°
• Remove the lower crankcase and measure the width of the
compressed plastigauge using the envelope scale. This mea-
surement should be taken at the widest part of the com-
pressed plastigauge.
Crankshaft journal oil clearance:
Standard: 0.010 – 0.028 mm (0.0004 – 0.0011 in)
Service Limit: 0.080 mm (0.0031 in)
• If the oil clearance exceeds the service limit, select the speci-
fied bearings from the bearing selection table.
Never rotate the crankshaft when a piece of plasti-
gauge is installed.
