(6) CAM CLEARANCE ADJUSTMENT
The cam clearance measured with the set point will have to be recorded to note the difference in set point.
(Example) Measured amount 0.27 - Set point 0.16 = 0.11 ・・・Set Point Difference
3
To adjust the cam clearance set point, you can do so by selecting the correct shim thickness for each point.
You'll have to calculate by inserting the guage under the lever ratio
of the rocker arm (start point is 1.43).
