Checking and Aqjusting Injection Timing
1) Disconnect the injection pipe from the fuel injection
pump.
2) Set the qcceleration lever for maximum fuel discharge.
3) Turn the flywheel until fuel jets out from the delivery
valve holder of the fuel injection pump.
4) Continue to turn the flywheel slowly, and stop it as soon
as the fuel level at the tip of the valve holder begins to in ­
crease.
5) Check to see if the FI mark on the flywheel is aligned
with the dot mark.
6) If the timing is out of adjustment, readjust with shims.
• Adding or removing one shim (0.15 mm, 0.0059 in.)
varies the crank angle by approx. 1.5°.
• After adjUstment, apply a thin film of non-drying adhesive
to both sides of the shims.
