MAINTENANCE AND LUBRICATION 193
MAINTENANCE INTRODUCTION
Preventive maintenance is vital to the life of your new vehicle. This section of the Operator’s
Handbook covers items of importance concerning the proper care of MACK vehicles. A
well-run maintenance and lubrication program is the best way to ensure a long life of
productive operation.
The operator plays an important role in the proper care of this equipment. By performing
daily checks and observing the equipment while in operation, minor defects can be caught
and corrected before they become major problems. Make sure any problems are corrected
before putting the equipment into operation.
If you have any questions concerning the proper care, maintenance and lubrication of your
vehicle, or if you need help in developing a preventive maintenance program, contact the
service manager at the local MACK Sales, Parts and Service Center.
Note:
This handbook contains basic maintenance information. For complete maintenance
and lubrication procedures, refer to the
Maintenance and Lubrication Manual
.
TURBOCHARGER
The engine turbocharger operates at very high speed, temperatures and pressure. Turbo
bearing lubrication is critical, particularly for a newly installed turbo or one which has not
been operated for a period of time and all oil has drained from the bearing and shaft surfaces.
To avoid turbocharger bearing failure, the following instructions are recommended:
•
Start the engine at least every 30 days to ensure turbo bearing lubrication. Operate engine
at low idle for at least three minutes before increasing RPM or driving the vehicle.
•
If the engine has not been run for more than 30 days, turbo pre-lube procedure is
necessary:
1 Remove turbo air intake duct and oil line connection at turbo.
2 Fill oil inlet fitting to overflow with clean engine oil.
3 Using fingers at compressor wheel, carefully spin and wiggle the turbo shaft to
distribute the oil over all bearing surfaces.
4 Reconnect air intake duct and again fill turbo oil port to overflow, connect oil line
and start engine.
5 Operate engine at low idle for at least three minutes before increasing RPM or driving
the vehicle.
