Rotatable Flange in 39MT Provides Flexibility & Inventory Consolidation

The Delco Remy 39MT™ Heavy Duty Gear Reduction Starter gives you complete industry coverage with just 15 part numbers—all thanks to the rotatable flange feature. The 39MT—the only OE starter on the market with a rotatable flange—easily replaces competitive units and provides coverage for virtually every application. Whether you’re a fleet or a parts department, you’ll be able to improve service flexibility and part number consolidation with the Delco Remy 39MT rotatable flange starter.

The rotatable flange is made to be adjusted—and doing so doesn’t void the three-year warranty. Rotating the flange is easy. You simply remove the flange screws, rotate it and reinsert the screws. This ensures the starter aligns to the engine.

Additionally, the Integral Magnetic Switch (IMS) is rotatable, too—into six different positions. The IMS reduces voltage drop and ensures the solenoid receives the maximum available voltage in any starting condition.

Available in both 12 and 24 volts, the 39MT is made for almost any heavy duty truck, off-highway vehicle or transit bus—giving you one product that meets the needs of the majority of your customers. Best of all, with its signature speed, torque and reliability, the 39MT gives you the confidence you need that the trucks in your fleet will turn over and start—and let you hit the road.

The 39MT packs a lot of power in a small package:

  • Lightweight planetary gear design and high torque
  • Over Crank Protection (OCP) that protects the starter from thermal damage by automatically resetting at a safe operating temperature
  • 30% faster cranking speed performance than other starters on the market
  • Electrical soft start that rotates the pinion for proper ring gear engagement before cranking, minimizing tooth abutment related damage 
  • Sealed solid link solenoid that enhances reliability by eliminating contact welding in low system voltage situations
  • Sealed noseless configuration for minimized debris contamination
  • Cold temperature performance that exceeds the competition in peak power output at -20°C
  • 3 year/unlimited miles warranty
