GEARBOX
The gearboxes should not require additional lubricant unless the box is cracked or a seal
is leaking. It is recommended that the oil level be checked after 8 to 10 hours of operation.
If additional oil is required follow the steps below under OIL FILL PROCEDURE.
Use 85W/140 Gear Oil. Under no circumstances should the fill level exceed the fill
level marks on the dipsticks on the outboard boxes or past the Oil Fill Check Plug
on the rear of the Center Gearbox. Capacity of Left and Right Gearbox is Approxi-
mately 119 oz (3.7 QT) per box.
NOTE: Overfilling the Gearboxes can cause a buildup of pressure during operation
and blow out the seals and cause the excess oil to spew from the Vent Plugs!
ATTENTION: If Gearbox suddenly starts making an unusual noise, stop at once, check
for leaks and refill Gearbox as required.
1. Remove the oil filler plugs on top the Left and Right side Gearboxes
2. Add additional oil (as needed) of 85W/140 Gear Oil.
3. Check with dipstick on the filler plug.
4. Remove the vent plug from the top of the Center Gearbox and the top Oil Fill Check Plug from
the back of the Center Gearbox. Fill with additional oil (as needed) of 85/140 Gear Oil until oil
runs out the Oil Fill Check Plug hole.
5. Reinstall the vent plug and the check plug.
