Injection Timing Test (Fig. 20, 21)
Injection  timing  can  be  adjusted  by  installing  shims
under the pump body. The timing is important because
it  determines  when  the  fuel  enters  the  combustion
chamber.
7. Standard injection timing can be confirmed by the IT
marks  on  the  crankshaft  pulley   and  the  stationary
pointer on the crankcase (Fig. 21).
The center mark on the pulley represents 23  o BTDC;
standard fuel injection timing. The outside marks repre•
The most accurate method of timing is done with an
electronic diesel timing tester (available from major tool
supply companies).

sent 25  BTDC and 21   BTDC; the acceptable range of
injection timing.
The following method is an initial setting for starting the
machine.
Shims are available in different sizes from 0.2 to 1.0 mm
thick. Adding or removing a shim, 0.1 mm thick, will
change injection timing by 1  . Increase shim thickness

pump and nozzle. (The number 1 cylinder is opposite
from the flywheel end of the engine.)
if  injection  is  too  early.  Decrease  shim  thickness  if
injection is too late. (See Injection Pump Service in the
Fuel System Repairs section of this chapter.)
2. Set up the injection pump for the test:
A. Remove the delivery valve holder (Fig. 20). Re•
move the delivery valve assembly and spring.
B. Replace the valve holder and tighten it in place.
3. Put the throttle control in the middle of its range of
travel.
4. Slowly rotate the crankshaft counterclockwise from
the flywheel  end (normal rotation) until the    IT marks
(injection  timing  marks)  on  the  crankshaft  pulley  are
approximately 1/2 in. (21 mm) from alignment with the
stationary pointer on the engine gear case (Fig. 21).
Make sure the number 1 cylinder compression stroke is
approaching by checking the push rods. Both push rods
on the number 1 cylinder should be loose and the valves
closed.  If  either  push  rod  is  tight,  rotate  the  engine
crankshaft one full revolution and inspect the push rods
again.

5. Turn the ignition switch ON so the electric fuel pump
will supply fuel through the injection pump and out the
number 1 delivery valve holder.
6. Rotate the engine crankshaft SLOWLY in the normal
direction until the flow from the number one injection
pipe just stops. This is the moment of actual injection
timing. (A large screwdriver inserted between the trans•
mission drive hub and rubber coupler will provide control
and leverage to slowly rotate the engine crankshaft.)
