Monaco Cayman 2006 - Wet Hub

Cayman 2006 Chassis Information — Section 10 • 241
• Positive caster is the tilt of the top end of the kingpin toward the rear of the motorhome.
• Negative caster is the tilt of the top end of the kingpin toward the front of the motorhome.
Setting the caster angle more positive than specifi ed may result in excess steering effort and/or shimmy.
Decreasing the angle may result in the motorhome wandering or poor steering return to center. The caster angle is
determined by the installed position of the steer axle.
Wet Hub
The front axle uses oil to lubricate the wheel bearings. The oil is drained and refi lled without removing the
wheel end assembly. Remove the hubcap to access the bearing cover and drain plug. Inspect the oil level before
every trip or every 1,000 miles.
To inspect the oil level:
• Remove the chrome hubcap.
• Locate the full and add mark on the outside of the clear plastic cover.
• If the lubricant level is low, add the recommended fl uid until full.
The recommended oil change interval is based on the operating conditions, speeds and loads. Limited
service applications may allow the recommended interval to be increased. Severe applications may require the
recommended interval to be reduced.
INFORMATION:
For more information, contact a Westport Axle service representative.
Recommended Interval Change:
• Change the fl uid whenever the seals are replaced, the brakes are relined or at 30,000 miles (48,000km).
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:
• EP S.A.E. 90w. 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).
