24.6.3 CHANGE OIL IN ENGINE OIL PAN, REPLACE
ENGINE OIL FILTER CARTRIDGE
The oil is at high temperature after the engine has been oper-
ated, so never change the oil immediately after finishing op-
erations. Wait for the oil to cool down before changing it.
Prepare the following
• Container to catch drained oil: Min 24 l capacity
• Refill capacity: 24 l (6.34 US gal, 5.28 UK gal)
• Filter wrench
1. Place a drain container under drain tap P located on the bottom of
the machine.
2. Loosen drain tap P slowly to avoid getting oil on yourself, and drain
the oil.
3. Check the drained oil, and if there are excessive metal particles or
foreign material, please contact your Komatsu distributor.
4. Install drain tap P
5. Open the engine hood. Using the filter wrench from the upper side of
the engine, turn filter cartridge a counterclockwise to remove it.
In particular, if this operation is carried out immediately after stopping the
engine, a large amount of oil will come out, so wait for 10 minutes before
starting the operation.
6. Clean the filter holder, coat the packing surface of a new filter car-
tridge with engine oil, and fill the filters with clean lubricating oil (or
coat it thinly with grease), then install it to the filter holder.
REMARK
Confirm that no remnants of old packing still adhere to the filter
holder as this may result in oil leakage.
7. When installing, tighten until the packing surface contacts the seal
surface of the filter holder, then tighten it up further 3/4 of a turn.
8. After replacing the filter cartridge, add engine oil through oil filler F
until the oil level is between the H and L marks on dipstick G.
For details of the oil to use, see 20 “USE OF FUEL, COOLANT AND
LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE”.
9. Run the engine at idling for a short time, then stop the engine, and
check that the oil level is between the H and L marks on the dipstick.
For details, see 24.3 “CHECK BEFORE STARTING”.
Replace once every 6 months, regardless of the number of hours
operated.
