2. Turn the handwheel until the T mark on its periphery matches the line marked on the radiator
to adjust the piston in the upper dead center in the compression stroke. (Fig.9).
3. Loosen the locking nut and turn the rocker adjusting screw with a screwdriver to adjust the
valve clearance to the specified value (the intake valve gap is 0.35mm, and the exhaust gap is
0.45mm) using a gauge inserted between the valve stem and the rocker (Fig.10).
4. During adjustment, tighten the adjusting screw so that the tensioning rod is free to rotate, but
not too loose. After that, tighten the lock nut to prevent it from loosening afterwards.
5. Remove the gauge, and re-check the valve clearance.
Adjusting injection time
Disconnect fuel line from high injector pressure.
1.
2. Loosen the nut connecting the high pressure fuel line to the injection pump, rotate the
tube so that the open side of the tube is up, and retighten the nut as shown in Fig.11.
Then prime the injection pump until the high pressure fuel line becomes full of fuel. 3.
Turn the flywheel slowly until the fuel begins to flow out through the pipe stub. Stop
turning and check that the line of the injection timing mark on the steering wheel
periphery coincides with the mark line on the radiator. If the injection timing is too
advanced or too late, then adjustment is necessary and should be performed according
to the following procedure
.
(1) – Close the fuel filter cock.
(2) - Set the speed control lever knob to the center position.
(3) - Disconnect the high pressure fuel line from the fuel pump.
(4) - Loosen the fixing screws of the pump and remove the pump.
(5) - Increase or decrease the number of joints. Increase the number of shims if the injection
timing is advanced. Reduce number of joints if delayed (Fig. 12)
