Overview

The 39MT is Delco Remy's heavy-duty gear-reduction starter, using a planetary gear set to deliver high torque output from a significantly more compact and lighter package than equivalent straight-drive models — weighing just 30.8 lbs (14 kg). Available in 12V (7.3 kW) and 24V (9.0 kW), it cranks up to 30% faster than comparable starters. Its sealed noseless design, electrical soft-start, and built-in over-crank protection make it especially well suited to demanding duty cycles and cold-weather operation.

Key Features

  • 12V at 7.3 kW and 24V at 9.0 kW peak output — up to 30% faster cranking than competitors
  • Planetary gear-reduction motor; weighs only 30.8 lbs (14 kg)
  • Starts engines up to 15 Liters (12V) and 16 Liters (24V) displacement
  • Electrical Soft-Start — rotates pinion into mesh before full cranking torque is applied
  • Sealed noseless design minimises debris accumulation in harsh environments
  • Built-in Over-Crank Protection (thermal circuit breaker) and rotatable flange for service flexibility

Applications

  • Heavy-duty on-highway trucks and vocational vehicles
  • Transit and commuter buses
  • Construction and off-highway equipment
  • Emergency response vehicles (fire, ambulance)
  • Applications requiring compact packaging with high torque output
