If agreed otherwise in writing signed by Webb Wheel, original equipment manufacturers installing UltraSet pre-adjusted hub assembly on new tractors and trailers could be eligible for longer warranty coverage.

Lubricant Criteria

WEBB WHEEL ULTRASET WHEEL END SYSTEMS

Lubricants currently approved for use in Webb UltraSet pre-adjusted wheel end systems all meet the following criteria:

The lubricant must be specified for wheel end or drive applications.

Lubricant Type/Grades
– Oil Synthetic/Mineral

Meets the requirements of SAE J2360 (MIL-PRF-2105E) or API GL- 5/MT-1.

Example of weights:
75W-90, 80W-90
80W-140, 85W-140

Semi Fluid Grease
Recommended Minimum Operating Temperature Limits of –20F to 325F [-29C to162C]*

Note: grease condition needs to be reviewed periodically during storage (i.e. separation and proper mixing) contact your lubricant provider for lubricant audit of quality.
Note: grease condition and fill needs to be reviewed following TMC RP631 recommendations.

*Lubricants on Webb Wheel’s approved list that do not meet these temperature limits have been thoroughly tested by Webb Wheel to ensure reliable performance.

ULTRASET PRE-ADJUSTED WHEEL END SYSTEMS
Any premium lubricant exhibiting the above characteristics and is listed by the lubricant manufacturer as a long-life lubricant is approved for use. Both product specification information and lubricant compatibility should be obtained from the lubricant manufacturer.

On-Highway Truck Applications
Webb Wheel UltraSet pre-adjusted truck wheel end systems are designed and approved for oil bath applications only. Use of semi-fluid or hard pack grease will result in loss of warranty coverage. Please reference the “Oil Synthetic/Mineral” section above for currently approved oil specifications.

On-Highway Trailer Applications
Webb Wheel UltraSet pre-adjusted trailer wheel end systems are designed and approved for oil bath or semi-fluid applications only. Use of hard pack grease will result in loss of warranty coverage. Please reference the “Semi-Fluid Grease” section above for specifications.

Off-Highway/Severe Duty Applications
Lubricants used for the Webb Wheel UltraSet standard 1-year packages must be typical hard pack grease, gear lube, or semi fluid greases designed for heavy duty wheel ends.

Webb Wheel will not approve the use of 50 weight transmission lubes or motor oil inside Ultraset wheel-ends. Wheel end performance & wheel seals can be compromised when these lubricants are used. Fleet preference may play a part in the wheel end lubricant selection decision. Ultimately, the choice of wheel end lubrication is a customer decision and responsibility. Please follow all related Technology & Maintenance Council recommended practices for wheel end maintenance such as RP 622, 624, 631, and 644.

Contact your Webb Wheel sales representative with questions or concerns.
