[3] OIL REPLACEMENT IN WINCH REDUCTION GEAR CASE
• Oil is at elevated temperatures immediately after engine operation. Do not remove the port
plug immediately. Wait until the oil cools down.
• Oil and the plug may pop out due to the internal pressure inside the winch case. Release the
pressure by loosening the plug slowly.
CAUTION
• Refer to “Inspection and Maintenance 7.1 Use of Fuel and Lubricating Oil According to
Temperatures” for the oil to be used.
• Use seal tape at the thread of each plug to prevent oil leaks and securely tighten the plug after
changing the oil.
•
Oil drain pan: Prepare a container for at least 1 litre.
•
Allen key to remove a plug: 8 mm
•
Oil replacement quantity in slewing reduction gear case: 0.75 litres
1. Place the machine on a level surface.
2. Fully retract and lower the boom as shown on the right,
setting it horizontal.
3. Slowly rotate the winch so that the plug (P) is pointed
directly towards the ground.
4. Place a container to collect the drained oil underneath the
plug (P).
5. Loosen the plug (P) slowly using an Allen key and remove
it while releasing the internal pressure. Gear oil in the
reduction gear case is drained.
6. When the gear oil in the reducer case is completely
discharged, slowly rotate the winch so that the plug (P)
can be seen from the opening hole.
7. Feed the gear oil through the oil level check plug (P) hole
using an oil pump.
8. Fit and securely tighten the plug (P) after replenishing oil.
[4] INSPECTION OF INTAKE VALVE / EXHAUST VALVE
For inspection, special tools and expertise are required. Contact us or our sales service agent.
NOTES
•
Wipe away cleanly whenever the oil spills.
• If it is difficult to drain the oil, attach the plug (P), fully extend and raise the boom, and then repeatedly
wind up and unwind the winch until the surface of the winch (around plug (P)) feels warm to the touch.
Then proceed from step 2.
• If the surface of the winch becomes too hot that you cannot touch, wait until the temperature drops and
then proceed work.
