M11-280E PLUS.
LINE-HAUL GEARING RECOMMENDATIONS.

The M11-280E Plus engine is ideal for on-highway applications hauling up to 80,000 lb GCW for speeds up to 60 mph.

This engine delivers outstanding performance in the 1200-1800 rpm range. The road speed governing feature of CELECT™ Plus provides precise control of top road speed and further improves fuel economy and performance.

Check the desired maximum road speed one gear down from top gear. If the maximum road speed is able to be maintained one gear down, the gear-down protection feature should be set approximately 4 mph below the maximum road speed setting. The gear-down feature will ensure that the vehicle is in top gear before the maximum road speed can be reached.

The following charts list some of the acceptable combinations for top gear road speeds between 55 and 60 mph with approximate engine speeds in the 1500-1700 rpm range. These gearing combinations provide the full advantage of the performance and fuel economy benefits of the M11-280E Plus engine.

VOCATIONAL GEARING RECOMMENDATIONS.

The M11-280E Plus with 2100 rpm governed speed is ideally suited for vocational applications. The higher governed speed matches well with overdrive and deep-reduction ratio transmissions.

Vocational applications require special attention to low-speed maneuverability and startability. Therefore, the overall gear reduction (lowest transmission gear x rear axle ratio) for mechanical transmissions should be approximately:

On/off-highway 60:1
  -------------------------
 Dumper 70:1
 --------------------------
 Mixer 100:1

 M11-310E PLUS LINE-HAUL GEARING RECOMMENDATIONS. 

The M11-310E Plus is an ideal engine for on-highway applications hauling up to 80,000 lb GCW for speeds up to 62 mph.

This engine rating delivers outstanding performance in the 1200-1800 rpm range. The road speed governing feature of CELECT Plus provides precise control of top road speed and further improves fuel economy and performance.

Check the desired maximum road speed one gear down from top gear. If the maximum road speed is able to be maintained one gear down, the gear-down protection feature should be set approximately 4 mph below the maximum road speed setting. The gear-down feature will ensure that the vehicle is in top gear before the maximum road speed can be reached.
