How to renew the lubricating oil of the Newage PRM 500D reverse gearbox
Caution: In service the lubricating oil of these reverse gearboxes should be checked with the lubricating oil
cold. Always check the lubricating oil level before the transmission is used.
1. Put a suitable container with a capacity of at least 3 litres (5 pints) under the reverse gearbox. Remove
the drain plug (V3) and its sealing washer and drain the oil from the reverse gearbox.
2. Inspect the sealing washer for the plug and, if necessary, renew it. Fit the drain plug and its sealing
washer. Tighten the plug.
3. Rotate the hexagonal head of the dipstick (V1) counter-clockwise to release the dipstick and remove
it from the dipstick / filler tube. Ensure that the sealing washer is not lost. Add lubricating oil of the correct
specification through the dipstick / filler tube, see section 9 for the correct quantity and specification.
4. Ensure that the sealing washer is on the dipstick. Fit the dipstick fully into the dipstick / filler tube.
Rotate the hexagonal end of the dipstick clockwise until the dipstick is tight in the tube.
5. Ensure that the reverse gearbox is in neutral (lever in the centre position). Start the engine to allow the
lubricating oil in the reverse gearbox to circulate around the system, approximately 15 seconds. Stop the
engine and wait approximately two minutes.
6. Remove and clean the dipstick. Insert and tighten the dipstick finger tight into the dipstick / filler tube,
then immediately remove the dipstick to check the oil level. Check that the oil is at the full mark (V2 ) and, if
necessary, add more lubricating oil.
7. Ensure that the sealing washer is on the dipstick. Fit the dipstick fully into the dipstick / filler tube. Rotate
the hexagonal end of the dipstick clockwise until the dipstick is tight in the tube.
