MAINTENANCE (Continued)
Lubricating the Drive Pawls
• Support the rear wheels off the ground.
• Remove the rear hubcaps and wheel plugs (refer figure 30).
• Inspect the inside of the wheel hub through the wheel plug hole. If dirt is found, the wheel should be removed and
cleaned.
• To remove the wheel, remove the ratchet plate securing the wheel to the axle.
• Withdraw the wheel from the axle and clean out thoroughly.
• Using clean engine oil, apply a few drops of oil to the end of the drive gear above the retaining washer and
rotate the gear to allow the oil to penetrate (refer figure 31). The gear should rotate freely, if not, repeat the
above procedure.
• Replace the wheel, washer and secure with a new ratchet plate.
• If the wheel hub is clean, rotate the wheel until the drive gear is visible through the wheel plug hole.
• Using clean engine oil, apply a few drops of oil to the end of the drive gear (as above) and rotate the wheel one or two
times to allow the oil to penetrate. The wheel should rotate freely, if not repeat the procedure (refer figure 31).
• Replace the wheel plugs and the hubcaps.
• Use a thin bladed screwdriver or similar between the hubcap and the wheel to prise off the
hubcap, being careful not to over bend it.
• Ratchet plates require special tools to remove and replace them. If you are unsure, contact
your nearest authorized Rover dealer.
• Purchase new ratchet plates before removing the wheels as they are not reusable.
