Checking Oil Clearance between Crank Pins
and Crank Pin Bearings
1) Paste a press gauge onto the crank pin bearing with grease.
2)
Tighten the connecting rod onto the crank pin to the
specified torque
26.5
to
30.4
Nm.
(2.7
to
3.1
kgf·m,
19.52 to 22.42 fHbs).
3) Remove the connecting rod gently, and measure the
depression of the press gauge with a sheet of gauge (paper).
4) If the measurement exceeds the allowable limit, replace
the crankpin bearing.
(Note for measuring)
• Fasten the crankshaft so that it does not turn.
• Do not insert the press gauge into the crank pin hole.
• Crankpin bearing measuring points are shown below.
