2010 Mack TerraPro Series, LEU Series: First 5000 Kilometers (3000 Miles) Break-In Procedure

New Vehicle Break-In

To ensure many years of reliable, trouble-free operation, the following break-in procedures are recommended:

Note: Oil change, filter change and chassis lubrication are no longer required at the 3,000-mile vehicle break-in interval.

Note: When checking oil levels, the vehicle must be parked on level ground, and the units at normal operating temperature. Components must be filled to the correct level. DO NOT OVERFILL.

Note: Oil and filter change intervals in this manual pertain to components built by Mack Trucks, Inc. For information concerning oil and oil filter change intervals for vendor components, refer to the specific vendor component service literature.

During the First 5000 Kilometers (3000 Miles)

After the first 200 km (125 miles), retorque the wheel nuts using an accurately calibrated torque wrench. Recheck this torque again after 800 km (500 miles).

Check oil and coolant levels frequently.

Check brake and clutch adjustments per recommended maintenance schedule, and adjust as needed.

Observe the instruments often, and shut down the engine at the first sign of any abnormal readings.

Report all leaks, loose fasteners, unusual noises, etc., to the service representative at the nearest Mack dealership so they can be checked and corrected.

Check the spring clip torque (U-bolts). (On REYCO suspensions, also check equalizer nut torque.)

On chassis equipped with AIRTEKTM front axle air suspensions, retorque the U-bolts.

Check the U-bolt torque on the MACK air suspension at the end of the first 1600 km (1000 miles).
