55.NOTE: Remeasure the backlash and verify that
it is within specified range at all of the following
6 positions: 10 degrees, 30 degrees, 100
degrees, 190 degrees, 210 degrees and 280
degrees. It will be necessary to reset the
measuring equipment between measurements.
NOTE: The measurement must be taken with
the dial indicator gauge with holding fixture, a
5-mm allen wrench and worm clamp set up as
shown. Mark the Allen wrench with a file 80 mm
(3.149 in) above the driven gear shaft center.
Make sure the worm clamp and allen wrench
are not touching the balance shaft housing.
NOTE: For an accurate measurement while
measuring the gear backlash, insert a
screwdriver as shown into the crankshaft No. 1
crankweight area and set both the rotation and
the thrust direction with the screwdriver, using
a prying action as shown.
