CHASSIS INFORMATION — 10
To inspect the oil level:
The motorhome must remain stationary
for 30 minutes.
Remove the chrome hubcap.
Locate the full and add mark on the
outside of the clear plastic cover.
If the lubricant is low, add recommended
fl uid to proper level.

Oil Change Intervals

The recommended oil change interval is
based on operating conditions, speeds and
loads. Limited service applications may allow
the recommended interval to increase. Severe
applications may require the recommended
interval to reduce. For more information,
contact a Dana/Eaton service representative.
Recommended Interval Change:
Change the fl uid whenever the seals
are replaced, the brakes are relined or
at 30,000 miles (48,000 km). However,
check the lubricant twice a year (spring
and fall) for contamination. Change as
needed.
If yearly mileage is less than 30,000
miles, change the fl uid twice a year
(spring and fall).

Lubricant Type:
Texaco Star Gear Lubricant SAE
80w/90. Specifi cations, minimum
ambient temperature - 15º F (-26.1º
C). There is no maximum ambient
temperature. 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 lubricant.
Replace plug or cover plate and fi ll bearing
assembly with the recommended lubricant.

DRUM BRAKE MAINTENANCE

The drive and tag axle slack adjusters and "S"
cam shafts require periodic lubrication to ensure
proper brake operation. Lubricate every 10,000
miles or three months.

SHOCK ABSORBER

The shock absorber is a hydraulic
device used to dampen suspension/
body movement. Road surface
irregularities are compensated for by
the shock absorber. The Roadmaster
chassis incorporates the Bilstein shock
in the design of the exclusive air glide
suspension system. This shock absorber
is a telescopic, mono tube unit fi lled with
nitrogen gas and hydraulic oil. The result
of the mixture is uninterrupted damping
for the smallest of wheel defl ection.
By design, a self lubricating seal is used
to allow approximately 10% of the total oil
capacity to pass onto the piston rod. The gradual
process of oil loss does not affect performance
of the shock absorber during service life. This
process will be evident after a long period of
service by an oil fi lm on the body of the shock
absorber. Coating or fi lm on the body or rod is
indication the shock is functioning normally.
