Frequently Asked Questions
Can mDRIVE RMPTO be operated during Crawler Gear usage?
For the AMT 13 and 14 Speed Transmissions the Crawler Gears are mounted forward of the Transmission Main Case which in turn drives the transmission input shaft. This design will reduce the PTO Ratio when operated in Crawler Gears 1 or 2 (C1, C2). Should the reduced PTO Speeds affect the PTO Operation for your Application, the recommendation would be to use 1st or 2nd gear for PTO operation.
What is the minimum RPM I should operate my PTO, so that my vehicle will perform Regeneration during PTO mode?
Regeneration in PTO Mode - when a vehicle is being operated in PTO mode and a diesel particulate filter (DPF) regeneration is commanded, the engine must be run at a speed above the minimum speeds listed in the tables in Body Builder Manual, Section 9, Table of Contents / Regeneration in PTO Mode. The minimum speed setting can be affected by ambient temperature and/or altitude.
On Mack mDRIVE, with PTO engaged while in neutral, and then selecting Drive the PTO stops turning. Why?
Remember that the m DRIVE is an automated manual transmission with a clutch. With the PTO engaged while in neutral, when selecting Drive, the clutch is released, then the transmission shifts into gear. When the driver takes his foot off the brake pedal and presses the throttle pedal the clutch will reengage and the PTO will start to turn again. The transmission will not shift gears and driver is limited to about 6 MPH.
