Construction and Handling 

 

2.1 Fuel System 

 

 

Fuel system 

The fuel system schematic is shown in Fig. 1 with the fuel 
flowing in the direction indicated by the arrows. To bleed air 
from the system, loosen the vent plug “A” on the fuel filter 
and crank the engine until there are no more air bubbles from 
the vent. Tighten vent A’ and purge the air from the injection 
pump at vent “B” using the same procedures.

Fuel-filter 

The fuel filter is of the cartridge type shown schematically in 
Fig. 2. Under normal conditions it should only have to be 
replaced every 400 hours. To install, apply a small amount of 
fuel to the packing and tighten securely by hand. For 
removal, the use of a filter wrench 15221—86611 is 
recommended.

Fuel injection timing

 

Fuel injection timing is adjusted by changing the number of 
shims used between the pump and the gear case it fits into. 
See Fig. 3. One shim corresponds to approximately 1.5 
degrees in crank angle. Therefore, injection will take place 
1.5 degrees later when a shim is added and 1.5 degrees 
earlier when a shim is removed. The timing is correct when 
the pointer in the peephole on the side of the flywheel 
housing lines up with the “F 1” marked on the flywheel. See 
Fig. 4.
