Injection Pump Timing
TK376 Engine
This is the only timing procedure for the TK376
engine. It is not necessary to check the individual
cylinder timing.
1. Remove the injection line for the number one
cylinder from the delivery valve on the
injection pump and from the injection nozzle.
NOTE: The number one cylinder is the
cylinder at the flywheel end of the engine.
2. Remove the cylinder head cover (valve
cover/intake manifold assembly).
3. Place the engine at top dead center of the
compression stroke for the number one
cylinder. Refer to steps a through d.
a. Rotate the engine in the normal direction
of rotation (clockwise viewed from the
water pump end) until the number one
TDC mark on the flywheel lines up with
the timing mark on the starter mounting
plate. See Figure 134 on page 108.
b. Check the rocker arms on the number one
cylinder to see if they are loose.
c. If the rocker arms are loose, the engine is
at top dead center of the compression
stroke for the number one cylinder.
d. If the rocker arms are tight, the engine is at
top dead center of the exhaust stroke for
the number one cylinder. Rotate the engine
360 degrees to place the engine at top dead
center of the compression stroke for the
number one cylinder.
4. Disconnect the 8S wire from the starter
solenoid to prevent the engine from cranking
when the unit is turned On.
5. Activate the fuel solenoid and the fuel pump
by energizing the run relay using the Interface
Board Test mode. Make sure the
Diesel/Electric switch is in the Diesel
position. See the SPECTRUM TS
Microprocessor Diagnostic Manual, for
information about the Interface Board Test
mode.
6. Rotate the engine backwards
(counterclockwise viewed from the water
pump end) until the injection timing mark is
positioned about 1.0 in. (25 mm) below the
the timing mark on the starter mounting plate.
7. Use a clean towel to remove the fuel from the
top end of the delivery valve holder.
8. Slowly turn the engine in the normal direction
of rotation until you see the fuel rise in the end
of the delivery valve holder. Stop as soon as
you see the fuel rise.
CAUTION: The cylinders on the engine
are numbered from the flywheel end to the
water pump end. The number 1 cylinder is
next to the flywheel. The number 2
cylinder is the center cylinder. The
number 3 cylinder is next to the water
pump. The timing marks on the flywheel
are matched to this system.

CAUTION: Loosen all of the injection
lines at the injection nozzles to prevent the
possibility of the engine firing while it is
being rotated.
