4.12 Adjustments
4.12.1 Fuel injection timing
(1) Checking fuel injection timing:
- Set the governor lever on “RUN” position.
- Disassemble the high-pressure fuel line and install a line used for testing the fuel injection
timing.
- Turn the flywheel till the upper limit mark is aligned with the “V” scale mark on the
radiating fin of the cylinder.
- Turn the flywheel clockwise 15 degrees then turn 30 degrees counterclockwise from the
upper limit mark. Fuel should start to flow. If there is no fuel flow, turn the flywheel one
complete revolution.
- Turn the flywheel slowly until the fuel flows from the testing pipe. Immediately check the
mark angle of the flywheel with the scale mark of cylinder.
- Repeat the foregoing process three times to ensure the validity of the final value.
(2. How to adjust the fuel injection timing
* Disassemble the fuel injection pump and the construction flange.
* Add spacer shims if the fuel injection timing is too early otherwise reduce the shims. The
fuel injection timing will change one degree every 0.1mm spacer shim thickness changed.
4.12.2 Bleeding air from the fuel system
Following fuel system maintenance and whenever the unit runs out of fuel, air will enter the
system and possibly prevent the engine from starting. It will be necessary to bleed the fuel
system in the following manner:
(1)Set the governor lever on “RUN” position.
(2) Place the fuel cock in the Start position.
(3) Set the decompression handle on decompression position.
