2. Drain the gearbox oil completely.
3. Clean the oil drain plug from metal particles and replace the sealing washer. Screw in the oil drain plug and tighten it to the specified torque.
Oil drain plug tightening torque:
- f5MR1 gearboxes: 38 Nm
- gearboxes F5M42: 32 Nm
- gearboxes F5MV1: 35 Nm
4. Wipe the area around the oil filler plug. Unscrew the oil filler plug and remove the sealing washer from it (Fig. 12.4, 12.5). Fill the gearbox with oil to the level of the lower edge of the oil filler hole. To check the actual oil level, wait until it stops leaking., then: add oil to the gearbox until a new stream of oil flows out. The oil level will be correct after the flow of oil flows out stops.
