Oil Level Plug
Remove the oil level plug on the side of the gearbox, and ensure the oil is filled up to that level; see
Figure 6.2 (2).
To top up the gearbox oil level, remove the oil filler plug and carefully top up with oil until the oil starts
to flow from the level plug; see Figure 6.2 (1).
Use only the recommended grade of oil.
For further information refer to ‘Recommended Lubricants’, Section 6.13.
6.5.3
Oil Drain And Refill
To drain the oil from the gearbox, it is necessary to remove the gearbox from the machine.
Lift and support the machine on safety supports.
With assistance, support the blade carrier, remove the split pin and rotor castle nut and remove the
rotor from the splined gearbox output shaft. Refer to Figure 6.10 and Section 6.9.
With assistance, remove the four nuts and mounting bolts securing the gearbox to the machine.
Remove the gearbox.
Remove both the oil filler and level plugs and invert the gearbox over a suitable container and allow
the oil to drain.
Replacement is the reverse of removal, but tighten the mounting bolts and castle nut as specified in
‘Specific Torque Settings’, Section 6.14.
Dispose of the used oil and protect yourself against it in accordance with the guidelines set out in
Section 6.2.
