MAINTENANCE PROCEDURE
EVERY 4000 HOURS MAINTENANCE
Maintenance for every 100, 250, 500, 1000 and 2000 hours service should be carried out at the same time.
CHECK WATER PUMP
Check for leakage of water and oil around the water pump. If any
problem is found, please ask your Komatsu distributor to carry out
disassembly, repair, or replacement.
CHECK VIBRATION DAMPER
For the check and replacement of the vibration damper, special
tools are required. Contact Komatsu Ltd. or its distributor in the
territory for the replacement. It has to be replaced with a new one
in the following cases.
Mating mark (1) is notched both on the damper hub and on the
inertia member of the vibration damper to show any misalignment
between the two.
If this misalignment exceeds 1.6 mm (0.063 in), or if there is any
dent found on the damper metal surface deeper than 3.2 mm (0.1
in), then (2) the vibration damper must be replaced.
CHECK STARTING MOTOR
Contact your Komatsu distributor to have the starting motor checked.
If the engine is started frequently, have this inspection carried out every 1000 hours.
