Drive Axle Removal
WARNING
When putting the lift truck on blocks, make
sure the surface is solid, even, and level. Any
blocks used to support the lift truck must be
solid, one-piece units.
1. Put blocks on each side (front and back) of the
steering tires to prevent movement of the lift
truck.
2. Raise the lift truck and put blocks under the
frame so that the drive wheels do not touch the
floor. Put blocks under the counterweight for
stability.
3. Remove the mast assembly as described in the
section Mast Repairs, 2, 3, and 4-Stage Masts

WARNING
On lift trucks with pneumatic tires, completely
remove air from tires before removing them
from lift truck. Air pressure in tires can cause
tire and rim parts to explode, which can cause
serious injury or death. Never loosen nuts that
hold together inner and outer wheel halves
when there is air pressure in tire.
4. Remove the wheels.
5. Remove the oil fill/level plugs on both sides of the
drive axle. See Figure 2.
6. Remove the oil drain plug (LH) from the drive
axle to drain the oil from the left-hand side of the
drive axle into a suitable container. See Figure 2.
7. Remove the oil drain plug (RH and center sec-
tion) to drain the oil from the right-hand side
and center section of the drive axle into a suit-
able container. See Figure 2.
8. Remove the brake discs oil drain plug from the
drive axle to drain the brake oil into a suitable
container. See Figure 2.
