Mack Trucks launched split-shaft function for mDrive HD

179

Mack Trucks  unveiled a standard split-shaft functionality for its 12-, 13- and 14-speed mDRIVE HD automated manual transmission.

Mack Construction Product Manager Tim Wrinkle says the split-shaft functionality offers the benefits of the mDRIVE transmission to customers who need higher PTO power and torque.

Rather than taking power from an engine- or transmission-mounted PTO, split-shaft PTOs are mounted in the middle of the driveline to get output directly from the transmission, supplying more torque for auxiliary equipment.

When the split-shaft PTO is engaged, power to the axles is disconnected.

All GHG2017 F-Series mDRIVE HD AMTs can be reprogrammed with split-shaft functionality with assistance from the Mack Body Builder Support Group, allowing the transmission start in 7th thru 12th gears and shift to a desired continuous operation gear of 11th or 12th.
