When setting valve clearances, the
following should be adopted:
(a)
With the valves rocking on No. 4
cylinder (i.e., the period between
the opening of the intake valve
and the closing of the exhaust
valve), set the valve clearances on
No. 1 cylinder.
(b) With the valves rocking on no. 2
cylinder, set the valve clearances
on No. 3 cylinder.
(c)
With the valves rocking on No. 1
cylinder, set the valve clearances
on No. 4 cylinder.
(d) With the valves rocking on No. 3
cylinder, set the valve clearances
on No. 2 cylinder.
b. Request Direct Support maintenance to
service fuel injectors as follows:
1)
Normally, defective injectors can be
isolated by loosening the pipe union
nut on each injector in turn while the
engine is running at approximately
800 rpm. As each nut is loosened, fuel
will not be injected into the associated
cylinder and, as a result, the engine
rpm will decrease if the injector was
previously functioning normally. If the
engine rpm remains constant, the
injector is probably defective.
