TAMPA, Fla. — Remy International has unveiled a redesigned starter to focus on challenges that come with new engine designs and strict anti-idling rules.
The 44MT is promising a combination of faster starts and more reliability, even in extreme weather. And unlike past Remy introductions, this one is being unveiled to fleets and the aftermarket before Original Equipment Manufacturers.
“We’re packing in much more power in the same envelope,” explains president Jay Pittas, comparing the new design to the 39MT. While both designs weigh about 15 kg, the 44MT boasts an extra 1.5 kW of power at 12 volts. Cranking speeds are also up to 115 rpm at 0F.
“This cranking speed is really everything. This is the thing that defines how fast that engine will turn over,” he said.
Features to improve reliability include an Internal Magnetic Switch Solenoid, which is shielded from corrosion and vibration challenges. The new Clutch Over Planetary Gear Drive System has a more robust clutch shell and ring gear to withstand more torque. The idea here is to slowly rotate the pinion until it engages with the ring gear before cranking, reducing engagement milling and teeth abutments.
Meanwhile, Integrated Over Crank Protection – the circuit breaker that protects the starter from thermal damage – is a self-contained, single-wire design, eliminating the need for a vehicle wiring harness.
Installation is said to be simpler because of a new self-contained design that eliminates exposed wiring and the need for added mounting brackets.
The designs will be available by the end of the year, at a premium of $100 to $120, although that would still pale in comparison to the cost of a $500 jump start.
