Recommended Interval Change:
The recommended oil change interval is based
on the operating conditions, speeds and loads. The
recommended fluid replacement is every 30,000
miles or annually. Limited service applications may
allow the recommended interval to be increased.
Severe applications may require the recommended
interval to be reduced. For more information, con-
tact a Westport service representative.
Remove the filter plug and add lubricant. Allow
the oil to flow through the bearings (this will take a
few minutes), double check to see if the oil level
has reached the oil level line on hubcap face. Use
EP-SAE 90 gear oil or any good equivalent petro-
leum base or synthetic lubricant.
CAUTION:
Do not mix petroleum based oil with synthetic based oil. This could cause an oil
seal failure.
Lubricant Type:
• Standard EP-SAE 90 wt. API GL-5. Lubricant temperature must never exceed 250º F (+121º
C).
To Drain:
• Place a suitable container below the bearing cover and remove the drain plug. If the cover
does not have a drain plug, remove the screws retaining the cover plate to drain the lubri-
cant.
• Replace plug or cover plate and fill bearing assembly with the recommended lubricant.
Lubrication Maintenance Safety:
Maintenance for the system entails a periodic lubrication of the front axle components. Chock
wheels for safety prior to accessing components underneath the
motorhome.
Lubrication of the front axle is critical in order to avoid premature wear
of the king pin assemblies and other components. Grease zerks are located
at the king pin assemblies (two on each side of the axle, upper and lower)
and one grease zerk on each end of the tie rod. These points require lubrica-
tion every six months or 5,000 miles with grease meeting NLGI #2 specifi-
cations.
NOTE:
Use only a hand operated grease gun on the fittings.
