ArvinMeritor Inc. announced that Meritor MXL (Meritor Xtended Lube) drivelines have been selected as standard equipment on all Daimler Trucks North America heavy-duty vehicles. New Freightliner Cascadia, Coronado and Coronado SD and Western Star trucks with a start of production after April 26 will incorporate this component change.
Designed for truck operators who seek reduced maintenance costs and a longer warranty, Meritor MXL drivelines feature 100,000-mile lubrication intervals for both U-joints and the slip section, along with a three-year 350,000-mile linehaul warranty. The Meritor 17, 176 and 18 RN series drivelines will transition to the enhanced MXL series in new truck production. They are compatible with standard RN yokes to simplify parts inventories and facilitate upgrades for in-service vehicles.
The company says the MXL has a 100,000-mile lubrication interval that also aligns with recommended lubrication intervals of other chassis components in linehaul vocations, helping truck owners manage routine preventive maintenance and control expenses. The MXL – which joins the RPL permanently-lubricated driveline in the Meritor family of driveline products for commercial vehicles – incorporates similar design characteristics of the RPL seal design, combining an advanced nitrile seal and protective shield to increase slip assembly operating life.
The company says the U-joint builds upon Meritor’s high-strength RN series design: Its needle-bearing package with contoured ends minimize axial (side) loading, and the glass-reinforced nylon thrust washer prevents metal-to-metal contact, all of which result in greater reliability and longer life.
