Drive Unit MP MPBB 040 AC

Find complete drive units and propulsion assemblies for electric pallet jacks, walkie stackers, and rider pallet trucks. Our Drive Unit collection covers integrated motor-gearbox assemblies, drive unit components, and traction system parts for the most common electric material handling equipment in service today.

Compatible equipment brands include Crown, Yale, Raymond, Hyster, BT Prime Mover, Toyota, and other major OEM and aftermarket manufacturers. Drive units are matched by equipment make, model, voltage, and drive unit specifications for verified fitment.

Drive unit types and components available:

  • Complete Drive Units — fully assembled motor-gearbox units ready for direct replacement
  • Traction Motors — DC and AC traction motors for drive unit rebuilds
  • Gear Assemblies — reduction gear sets and differential assemblies
  • Drive Wheels — drive wheel assemblies matched to drive unit output shaft specs
  • Brake Assemblies — electromagnetic brakes and brake components for drive units

How to identify the right drive unit: Note your equipment's make, model, serial number, and system voltage from the data plate. For complete drive unit replacements, also note the drive unit manufacturer (often stamped on the unit housing) and the output shaft configuration. Confirm voltage and gear ratio compatibility before ordering — mismatched gear ratios affect travel speed and motor load.

With 410+ drive unit SKUs in stock, most parts ship same or next business day from our US warehouse.
