and recheck end clearance. If clearance is
within limits, remove starting jaw (1) and
washer (2).
(18) Check clearance between crankshaft
and camshaft gears as follows. Using a screw
driver, pry teeth on gears as far apart as pos-
sible. Check clearance with feeler gauge as
shown in figure 6-22. Clearance shall not ex-

maximum clearance is exceeded, replace both
camshaft gear and crankshaft gear as the two
timing gears are matched pairs.
