INSTALLING BOLT
1. 1D4539 Bolt, 5/16 in.-18NC, 2.5 in. (63.5 mm) long.
2. Timing hole. 3. Hole.
4. The intake and exhaust valves for No. I cylinder
must now be closed and the timing pointer will
be in alignment with the TDC-I on the damper
assembly. The No. I piston is now at top center
on the compression stroke.
FUEL SYSTEM ADJUSTMENTS
Checking Fuel Injection Pump Timing; On Engine
The timing of the fuel injection pump can be
checked and changed if necessary, to make
compensation for movement in the taper sleeve
drive or worn timing gears. The timing can be
checked and if necessary, changed using the
following method.
Checking Timing by Timing Pin Method
Tools Needed:
5P2371 Puller.
3P1544 Timing Pin.
I. Remove bolt (I! from the timing pin hole.
TIMING HOLE BOLT
1. BOLT
2. Turn the crankshaft COUNTERCLOCK- WISE (as
seen from rear of engine) until timing pin (2)
goes into the notch in the camshaft for the fuel
injection pumps.
3. Remove the plug from timing hole (4) in the front
cover. Put bolt (3) through the front cover and
into the hole with threads in the timing gear. The
bolt from hole (5) can be used.
TIMING PIN INSTALLED
(Typical Example)
2. 3P1544 Timing Pin.
INSTALLING BOLT
3.1D4539 Bolt, 5/16 in.-18 NC, 2.5 in. (63.5 mm) long.
4. Timing hole. 5. Hole.
4. If the timing pin is in the notch in the camshaft for
the fuel injection pumps, and bolt (3) goes into
the hole in the timing gear through timing hole
(4), the timing of the fuel injection pump is
correct.
NOTE: If bolt (3) does not go in the hole in the timing
gear with timing pin (2) in the notch in the camshaft,
use the following procedure.
