3.9 Measuring timing gear backlash
Measure the backlash of the timing gears by using one of
the following two methods; measure the gear play with the
dial gauge plunger applied to a tooth flank on the pitch
circle at a right angle to the tooth axis, or measure the
clearance between gears by inserting a feeler gauge between
the gears at the tooth-to-tooth contacting area. Replace the
faulty gear pair if the limit is exceeded.
