Use this checklist for the maintenance of your Mack truck. Maintenance checklists have proven to reduce repair costs for trucks and to avoid unnecessary damages.
Vehicle Break-In
To get the most from your new MACK truck, and to ensure many years of reliable, trouble-free operation, the following "break-in" procedures are recommended
During first 3000 Miles (5000 km)
After the first 125 miles (200km), retorque the wheel nuts using an accurately calibrated torque wrench. Recheck this torque again after 500 miles (800 km)
Check engine oil and coolant level frequently
Observe instruments often and shut down as soon as possible at first sign of any abnormal readings
Check for leaks, loose fasteners, unusual noises, etc., and correct as necessary.
Check spring clip torque (U-bolts). (Reyco suspensions: also check equalizer nut torque.)
Check the U-bolt torque on MACK air suspensions at the end of the first 1000 miles (1600 km) of service.
At the end of first 3000 miles (5000 km) or before 4000 miles (6500 km) or 3 to 4 months (whichever comes first)
Retorque spring clips (U-bolts). (Reyco suspensions: Retorque spring clips and equalizer nuts.)
