Replacing Filter Elements
I
MPORTANT
:
To protect new components of the hydraulic system, the return filter element must be changed after
the
first
50 hours of truck operation. Change the element twice a year afterwards (see E
The filter restriction indicator (see Figure 5
26) will indicate, when the engine is running, if the filter
needs to be changed. Replace the filter before the indicator reaches the red zone. This will keep the oil
clean, extend component life and reduce failures.

To replace the hydraulic filter:
1.
Lock out and tag out the vehicle (see
Locking Out and Tagging Out the Vehicle
2.
Prepare a pan or a bucket to collect the oil that will come out of the filter housing (two gallons of
oil).
3.
Remove the filter head cover bolts (four) [see Figure 5
27].
This in-tank return filter system contains a check valve that closes when the cartridge is removed,
thus preventing the whole tank from draining.
