Preventive Maintenance Program

Preventive Maintenance Program

Certain chassis vocations may require more frequent service intervals. When developing a maintenance program, review chassis operating conditions and adjust the service intervals as required. At each maintenance and lubrication interval, look at the condition of chassis lubrication points, condition of components, etc., and adjust your service intervals accordingly. Using a lubricant analysis program performed by a reputable laboratory is the most effective method of determining lubricant change intervals. Alter the maintenance program to meet your needs, but never exceed MACK recommended intervals.

Spicer Life™ SPL-170XL and SPL-250XL Driveshaft — U-Joint Lubrication

Spicer Life™ XL series driveshafts are equipped with “extended-lubrication” U-joints. These U-joints are easily identified by the blue plastic cover in the center of the U-joint cross where the grease fitting is usually located. The XL U-joints must be lubricated initially at the following intervals:

Highway Chassis: 560 000 km (350,000 miles) or 3 years*

Vocational Chassis (includes city driving and on/off highway: 161 000 km (100,000 miles) or 1 year*

* Whichever occurs first.

Following the initial lubrication outlined above, Spicer Life™ XL series U-joints must be lubricated at the following intervals:

Highway Chassis: 161 000 km (100,000 miles) or 6 months*

Vocational Chassis:

—Severe Service: 32 000 km (20,000 miles) or 180 days*

—Extra Severe Service: 375 hours or 90 days*

* Whichever occurs first.

The slip-joints used with Spicer Life™ driveshafts are “Lubed for Life,” and protected by a bellows. Lubrication of these slip-joints is not required and the bellows must not be disturbed.

ArvinMeritor™ RPL20 and RPL25 Permalube™ Series Driveshafts

The U-joints and slip joints on the RPL20 and RPL25 series driveshafts are permanently lubricated and sealed. Lubrication at regular intervals is not required during the life of the driveshaft.

ArvinMeritor™ 92N Permalube™ Wing-Style Driveshafts

The U-joints used on the 92N Permalube™ Wing-Style Driveshafts are permanently lubricated and sealed. Lubrication at regular intervals is not required during the life of the driveshaft. The slip joints, however, must be lubricated at each specified chassis lubrication interval. Refer to the preventive maintenance schedules found on pages 17 and 20.

Note 2:An extended service drain interval of 804 600 km (500,000 miles) or 3 years, whichever occurs first, for Highway type operations is permissible for MACK geared drivetrain components (Transmissions and Carriers) IF MACK-specific GO-J PLUS Gear Lubricant is used. For Vocational operations, an extended drain interval of 128 800 km (80,000 miles), 1 year or 1,200 hours, whichever occurs first, is permissible if GO-J PLUS Gear Lubricant is used. An SAE 40 or 50 grade transmission oil, TO-A PLUS, is also available for use in all MACK transmissions. Extended drain intervals for transmissions using TO-A PLUS are 804 600 km (500,000 miles) or 3 years, whichever occurs first, for Highway operations, and 128 800 km (80,000 miles), 1 year or 1,200 hours, whichever occurs first, for Vocational operations.

If a MACK axle and/or transmission were initially filled with GO-J PLUS gear lubricant and later “topped-off” with greater than 1-1/2 quarts of GO-J specification gear lubricant, the drain interval is reduced to the GO-J limits (2 years or 402 300 km [250,000 miles]).
