Revised Oil Change Intervals
Mack revised the recommended oil change intervals for its ASET AC-460P and AC-460E engines. To keep engine wear to a minimum, engine oil and filters need to be changed at regular intervals before soot levels exceed 5% and oils that meet the company specification EO-N Premium Plus 03 high-performance diesel engine oil be used with approved oil filters.
Mack recommends oil analysis programs for monitoring the overall condition of the oil and for determining soot levels. The company approved two soot measurement methods: Thermogravimetric analysis and the light extraction method.
Figure 1 displays the revised specified oil and filter change interval for all ASET AC-460P and AC-460E engines.
Replacing Electronic Control Units
Unlike previous generations of electronic control units (ECU) where antilock braking system (ABS) units could be switched out, Bendix EC-60 Advanced ECUs are vehicle specific. Because the company customizes the stability system for the actual vehicle configuration and its sensors, the VIN is required to order replacement ECUs.
Bendix Advanced ABS ECUs intervene based on feedback from expected sensor locations and orientations. Install sensors in their original position and orientation on the vehicle, and recalibrate the sensors after related maintenance work.
