8. Fit injection pump timing gauge holder
LRT-12-121 into access hole.
9. Fit dial gauge and preload by approximately 2
mm. Secure dial gauge in holder.
10. Remove plastic plug from flywheel timing pin
access hole. Insert timing pin LRT-12-108.
11. Rotate engine slowly clockwise until dial gauge
needle reaches its lowest point. Zero gauge.
12. Continue turning crankshaft in a clockwise
direction until timing pin locates into flywheel.
Check reading:
Engines with less than
20,000 km = 0.95 mm
±
0.02 mm (0.4
±
0.001
in)
Engines with more than
20,000 km = 0.90 mm
±
0.02 mm (0.035

If in tolerance, continue at Assemble.
If out of tolerance, carry out adjustment as follows:

13. Slacken 2 flange nuts and 1 support bolt
securing FIP.
CAUTION: Slacken flange nuts by
minimum amount. Timing chain tension
will deflect pump if bolts are over loose,
leading to false readings.
14. Rotate pump on mounting until correct reading is
achieved.
NOTE: Ensure final movement of pump
head is made towards the engine.
CAUTION: If final movement of pump head
is away from engine, backlash will be left
in pump mechanism, leading to false
readings.
15. Tighten pump flange nuts to
22 Nm (16 lbf.ft)
16. Remove flywheel timing pin.
17. Repeat from operation 6 to verify timing.
