PROCEDURE TO DRAIN GEAR BOX OIL
PROCEDURE TO CHECK THE GEARBOX OIL LEVEL
12 MAINTENANCE
The gearbox oil change interval should be carried out in accordance with the requirements set out in the table on page 32. It is advisable
to replace the output shaft seal at the first oil change as this is the most important oil change to prolong the life of bearings, gears and
seals. The reasoning behind this is that whilst bedding in, gearboxes can generate fine metallic contamination. This will find its way to the
lowest part of the gearbox and collect in the output seal thus allowing an abrasive paste to wear the output seal. It is advisable that oil
changes are performed by a Digga Authorised Service Agent, however it is not always possible for many reasons to get this done by a
Dealer however what is important is that the oil is changed at the required intervals.
Remember to consider the environment, state and federal laws relating to disposal of oil. Dumping and spillage of oil onto land, storm
water outlets and waterways is illegal. Oil must be disposed of by professional waste disposal or recycle specialists.
1. Ensure that the gearbox is stable, secure and safe to work on prior and that the drive unit is vertical and that there is an appropriate
sized drip tray (Item no.5) to catch any oil spillage.
2. Before commencing to drain any oil, check the serial tag of the unit to determine the quantity of oil which the gearbox holds. This will
indicate the size of the drip tray needed to contain the oil as well as the quantity of oil which has to be replaced in into the gearbox.
Remove the drain plug (item 1) from the output housing. This will allow the bulk of the gearbox oil to drain out to an appropriate size
drum or bucket. (this will not drain the gearbox entirely and therefore the output shaft seal must be removed to totally drain all the
gearbox oil. Also this lower section of the output housing is usually where most foreign particles settle).
3. To drain the remaining oil which is below the drain plug level ensure that there is a drip tray to catch the oil spillage once the seal is
removed.
4. Proceed to remove the socket head cap screws which attach the seal protector to the output housing and remove the seal protector.
5. The output shaft seal can then be pried out.
6. The oil will dump into the drip tray.
7. Usually the inside of the seal will collect a sludge build up. Proceed to clean the seal or replace if it appears damaged.
Unfortunately, there is no provision to make a quick visual inspection of the gearbox oil level. The gearbox is filled to the correct level at the
factory. Unless there are clear signs of gearbox oil leakage it should not require topping up between scheduled services.
