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 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 uid twice a year
(spring and fall).
Lubricant Type:
Texaco Star Gear Lubricant SAE
80w/90. Speci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 ll bearing
assembly with the recommended lubricant.

DRUM BRAKE MAINTENANCE
The drive and tag axle (42' only) 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 lled with nitrogen gas
and hydraulic oil. The result of the
mixture is uninterrupted damping
for the smallest of wheel de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 lm on
the body of the shock absorber.
Coating or lm on the body or
rod is indication the shock is
functioning normally.
Road holding, handling, balance and braking
characteristics all can be contributed to the shock
absorber. The operating conditions for which the
shock absorber must endure will determine the
life span. However, since the only moving part is
the piston rod, there are no springs, hinges or pins
to wear out, get weak or deteriorate.
