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.
Refer to the preventive maintenance schedules outlined in the Maintenance
and Lubrication Manual (21394653) for recommended lubrication change
intervals for the following items:
• Gear oils (transmission, rear axle carrier[s], front drive axle carrier, transfer
case, flywheel PTO)
• Engine oil
• Oil filters
• Fuel filters
• Coolant conditioner
Note: It is important that components be filled with lubricants meeting the
specifications as given in the Maintenance and Lubrication Manual (21394653)
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.
