7. To continue the procedures for setting the
timing, refer to the following applications for
an engine with front timing indicator or with
rear timing indicator.
ENGINE WITH FRONT TIMING INDICATOR
E7 mechanically governed engines with
automatic transmissions use the Center Web
Vibration Damper with timing marks. The
vibration damper timing indicator and engine front
turnover bracket are used in this application.
1. Rotate the engine crankshaft counterclock-
wise (as viewed from the front of the engine)
to a minimum of 45 degrees before Top
Dead Center (TDC).
2. Rotate the engine crankshaft clockwise until
lamps A and B are both lit. Fuel injection
pump-to-engine timing is now set and the
injection pump can be removed from the
engine.
ENGINE WITH REAR TIMING INDICATOR
E7 mechanically governed engines with manual
transmissions and all V-MAC engines with
manual and automatic transmissions use the
flatback vibration damper with no timing marks.
They are also equipped with flywheel and
flywheel housings that incorporate engine timing
and turnover features. With rear timing, the front
timing indicator and engine front turnover bracket
are not utilized.
1. Remove all six 8-mm capscrews to access
the flywheel housing timing window.
2. Remove the plastic plug in the cast-
machined opening in the forward face of the
housing.
3. Insert engine barring socket tool J 38587
into the opening.
4. Install a 1/2-inch drive ratchet into tool
J 38587 to rotate the flywheel.
5. Rotate the flywheel counterclockwise to a
minimum of 45 degrees before TDC.
6. Rotate the flywheel clockwise in normal
direction (as viewed from the front of the
engine), until lamps A and B are both lit.
Fuel injection pump-to-engine timing is now
set and the injection pump can be removed
from the engine. Remove tool J 38587 from
the flywheel housing.
Fuel Injection Pump Driven Gear
Installation
To install the fuel injection pump gear:
1. Verify crankshaft is set to correct BTDC
position for pump timing.
2. Connect timing-light tool J 37077 (refer to
beginning of the section, Setting Static Fuel
Injection Pump Timing). Using hub rotation
tool J 38740, rotate the timing gear hub
clockwise until both lights A and B are lit.
Figure 7-20 — Rotating Timing Gear Hub Clockwise
앫 Use the proper hub rotation tool J 38740
which allows rotation of the hub only.
앫 Do not use the inner shaft nut (25 mm) to
rotate the timing gear hub.
앫 If the inner shaft nut is used to rotate the hub,
the nut may loosen, resulting in subsequent
failure.
