Over-Crank Protection on the Delco Remy 39MT protects the starter in adverse starting conditions such as cold-weather cranking, lower battery capacity, high-starting circuit resistance or operator misuse. Over-Crank Protection (OCP) is a built-in circuit breaker protecting the starter from thermal damage by automatically resetting at a safe operating temperature.
Reduce inventory costs today with the 39MT rotatable flange design. The Delco Remy 39MT Starter’s rotatable flange improves service flexibility and part number consolidation. Rotatable flange models easily replace competitive units and provide full industry application coverage of virtually every 12-volt and 24-volt application. By simply removing the flange screws, you are able to rotate the flange and align the starter to the engine.
The 39MT provides improved starter pinion engagement. Our innovative redefined electrical soft start reduces wear-and-tear by slowly rotating the pinion until it properly engages into the ring gear, before cranking. This also minimizes tooth abutment, ultimately helping to extend starter life.
The 39MT Starter pinion tooth lay-back chamfer improves engagement reliability. A double-sided chamfer provides smooth, reliable engagement and reduced wear on ring gear.
The Delco Remy 39MT includes several key features designed to ensure the starter reliability. One of those is the ideal number and spacing of spiral spline teeth that provide high strength and smooth engagement. Another is the optimum planetary gear ratio for transmission of high torque and speed. These features work together to ensure the vehicle starts every time.
The Delco Remy 39MT includes several key features designed to ensure the starter’s reliability. First, the larger gauge motor circuit wire translates to higher current draw and lower voltage drop. Additionally, a lower resistance solenoid ensures pinion engagement to ring gear. These features work together to ensure the vehicle starts—and keeps running.
The Delco Remy 39MT cranks up to 30 percent faster than the competition, including comparable Melco, and Denso models. The 39MT provides the durability and reliability you expect from Delco Remy starters.
