4. ENGINE
2. Hold the mating gear and move the gear to
measure the backlash.
NOTE
• If the backlash is more than the service limit,
measure the oil clearance in the journal part
of each shaft.
• If the oil clearance is correct, replace the
gear.
• If the crank gear is replaced, it is necessary
to calibrate the injection timing with the
diagnosis tool.
