Delco Remy Starter Motor 

The Delco Remy Starter Motor brings a high-output 24-volt crank capability to heavy-duty powerplants using a 50MT configuration. Its SAE 3 mounting pattern and clockwise rotation streamline installation on applications requiring a robust engagement profile. With an 11-tooth pinion and insulated polarity, this starter focuses on clean electrical transfer during high-draw startup cycles. The solenoid-to-motor coordination is arranged to deliver firm pinion meshing, reducing lag during the first rotation. Its newly assembled construction removes the uncertainties of remanufactured components, supporting a smoother transition during system refreshes. Trust the Delco Remy 10479339.
