BorgWarner recently introduced a new commercial vehicle starter—the Delco Remy Genuine Products 31MT.
The company says its 31MT starter provides increased reliability, durability and up to 10% more peak power than comparable products, making it a reliable solution for medium-duty commercial vehicle applications, such as delivery vans, emergency vehicles and school buses.
Developed from BorgWarner’s Delco Remy Genuine Products 29MT original-equipment (OE) platform, of which the company says there are more than 1.25 million OE units installed, BorgWarner’s 31MT model family provides a wide range of coverage for the Class 6 and 7 commercial vehicle aftermarket.
“BorgWarner’s new Delco Remy branded 31MT commercial vehicle delivery starter is expected to expand our product portfolio for medium-duty vehicles and fills the need for a durable, reliable starter for Class 6 and 7 commercial vehicles,” said Dr. Stefan Demmerle, president and general Manager of BorgWarner PowerDrive Systems.
“It is an ideal solution for applications that make a lot of starts and stops or operate under stressful driving conditions because it offers outstanding strength, power, durability and affordability.”
BorgWarner engineers made a series of design changes intended to improve the performance of the heavy-duty starter. These changes include a new silicon lamination armature for increased cranking power; enhanced commutator and a new bearing with O-ring for greater starter durability; and stainless brush springs and a new plated brush holder for added corrosion resistance and overall performance. The 31MT is compatible with stop/start systems, helping enable OEs to implement that fuel-saving strategy.
The 31MT commercial vehicle starter also features a positive shift engagement system, which is activated in case of tooth abutment. If this occurs, the armature rotation in full power clears the abutment to allow pinion engagement, preventing click-no-crank, which occurs when you turn a key and hear rapid clicking but the starter does not crank the engine. The positive shift engagement system enables a better driving experience and is particularly well suited for medium-duty commercial vehicles that have frequent stops and starts.
BorgWarner’s 31MT model can be used to upgrade existing parts for a variety of medium-duty vehicles from major commercial vehicle OE manufacturers with 12-volt engine sizes up to 9 liters. Each starter comes with a one-year, unlimited miles warranty for all makes, and an extended two-year warranty for school bus applications in North America.
