How to change your final drive oil
Manoeuvre your machine onto a level surface – and ensure the gearbox cover is clean to avoid dropping debris into the gearbox
Align the drain, level and fill plugs.
Step 2.
Remove the drain plug and collect old oil in suitable container.
Removing the filler plug at this stage will introduce air into the gearbox which will help it drain quicker.
Step 3.
Once the gearbox is empty, refit the drain plug and remove the level plug in preparation for the refill.
If your final drive only has 2 plugs (1 top and bottom) rotate the gearbox through 90° to determine where the oil level will be.
As a general rule, a gearbox will only be half full of oil – always check the manufacturers specs.
Step 4.
Using either a gear pump or suitable dispenser, add your new gearbox oil to the specified level. Then refit the level plug and filler plug.
Note
If the oil is particularly dirty, it’s recommended to fill the gearbox with a flushing oil – run then drain – to rid any contamination and sediment prior to final refill.
If your gearbox oil is heavily contaminated or contains a high level of metallic parts, this is an early sign of gearbox failure – contact your Local FDC Dealer for help.
If the oil level is low or no oil is left in the gearbox, this could be a sign of duo cone seal failure – contact your Local FDC Dealer for help.
