HYDRAULIc SYSTEM
On a walk around and pre-check of the
motorhome, look for oil leaks under the coach
and around hose fittings. If a hose connection
appears to be leaking, clean the filter and the
surrounding area. If seepage continues, have
the problem corrected to prevent an untimely
failure.
Hydraulic Reservoir
The power steering reservoir with internal
filter is located in the rear engine compartment.
The hydraulic filter assembly, located inside
the reservoir, is rated at ten micron*. The
reservoir is filled with 15W-40 motor oil.
Filter assembly: Nelson 91085G
Filter number: 84365A (ten micron*)
NOTE
Filter is accurate at time of printing.
Confirm part number before ordering
or obtaining replacement.
The primary function of the
power steering reservoir is
to keep the steering system
free of contamination and
to dissipate excessive heat
that builds during extreme
operating conditions.
Check the oil level in the
reservoir prior to each trip. The oil dipstick fill
is located on top of the reservoir. The oil level
should be kept between the full and add marks
on the dipstick. If adding of fluid is required,
use only 15W-40 motor oil.
Checking the Fluid Level:
Start the engine and allow it to reach
normal operating temperature.
While the engine is at idle, turn the
steering wheel left and right several
times.
Shut the engine off.
Rotate the grip handle
counterclockwise to remove the
dipstick.
Check the fluid level on the HOT side
of the dipstick in the area marked HOT.
DO NOT
exceed the full mark.
If the fluid level is low, add fluid in
small amounts, continuously checking
the level until the FULL mark is
reached.
Insert the grip handle back in the
reservoir and rotate clockwise until
securely fastened.
Power Steering Hydraulic Filter
A filter is located in the power steering
hydraulic reservoir. Replace the filter every
15,000 miles, or once a year, for cellulose
element.
Changing the hydraulic oil filter:
Using a wrench, typically 15/16”,
loosen the center cover bolt.
Remove the bolt and cover plate to
access the spring and filter.
Place a container under the
reservoir. Also have rags
handy to clean up any oil that
may spill.
Remove the spring and
washer to remove the filter
assembly. Use care because
oil may spill out.
After replacing the filter
assembly, reverse the process
to re-assemble the reservoir.
When attaching the cover
plate in the rubber cover seal, check for
any damage.
If needed, fill the reservoir to proper level.
Fill with new 15W-40 motor oil only. Never
reuse old oil. Start the engine and allow it to
reach normal operating temperature to purge
trapped air. While the engine is at idle, turn
the steering wheel left and right several times.
Shut engine off and confirm proper oil level in
reservoir.
AIR INTAkE & cHARgE AIR SYSTEM
The air intake and charge air system
supply the engine with clean air for proper
combustion and performance. Air entering
the system is cleaned through a replaceable
filter element and monitored with an air filter
restriction indicator.
The airflow through the air filter is passed
through the engine turbocharger, which
pressurizes and heats the air. The heated
pressurized air then passes through the charge
air cooler, where the air is cooled before
entering the engine intake manifold.
