3. Measuring oil clearance
1) Measure O.D of the crankshaft journal and pin.
2) Measure diameter of the crankshaft bore and connect-
ing rod bore.
3) Measure the thickness of the crankshaft and connect-
ing rod bearing.
4) Calculate clearance by subtracting O.D of the journal
pin and thickness of the bearing from diameter of the
bore.

Check the front and rear oil seal and replace it with new
parts if necessary.
Clearance between sensor wheel and
crank position sensor
0.5 ~ 1.1mm
If the clearance is out of specified values, check the sensor
wheel for balancing and the crank position sensor for in-
stallation and replace those if necessary.
