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
kgfOm,
19.52
to 22.42 ft-Ibs).
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. See engine
specifications.
