☞
Stop the rotary motion immediately
☞
Read the degrees before top dead centre by means of the indentation on the flywheel
➥
Rated value: 16° +/- 1° before top dead centre
– see
Marks on flywheel
on page 4-

☞
Measure the injection time two to three times
➥
If the specified value is reached, the injection time is correct
☞
Refit the fuel injection line, cutoff solenoid and cap
☞
Check the fuel system for leaks
➥
If the value varies from the specified value, the injection time must be adjusted
Notice!
Bend the injection lines as you mount them so they are not subject to tension once
they are mounted. Bleed the injection lines once they are installed.
Setting injection time
Variations of the injection time outside the tolerance range can be corrected by turning the
fuel injection pump.
➥
The injection time must be measured to determine whether it is premature or too late

Rotated away from the engine: earlier injection time
➥
Rotated towards the engine: later injection time

Bend each of the injection lines before you mount them so they are not subject to
tension once they are mounted
☞
Check the injection time again
– see
Checking injection time on page 4-9
