The 28MT is a gear reduction design available in 12 and 24 volt for medium duty engine applications up to 6.5 liter.
Developed from the 29MT design - of which there are more than 1.25 million OE units installed - the 31MT prodvides a wide range of coverage for Class 6 & 7 commercial vehicles. This robust, corrosion resistant starter is ideal for applications with frequent start and stops.
The 35MT is a gear reduction starter for medium duty applications providing more power in a smaller package with patented technology to reduce corrosion and vibration issues. The 35MT features a patented internal magnetic switch solenoid (IMSS) eliminating the need for an IMS switch.
The 37MT is a straight drive starter for medium duty applications with engine displacement up to 9.0L.
The 38MT is a gear reduction starter for medium and heavy duty applications featuring electrical soft start technology to prevent ring gear damage.
The 38MT+ is a gear reduction starter designed to fit PACCAR MX 11 and 13 Liter engines. The 38MT+ provides faster cranking speeds in a lighter package compared to the competition. Available with Integrated Over-Crank Protection (IOCP), a built-in circuit breaker, protects the starter from thermal damage, automatically resetting at a safe operating temperature while eliminating the need for a wiring harness. The IOCP protects the starter in adverse starting conditions, such as cold weather cranking, lower battery capacity, high starting circuit resistance or operator misuse.
The 39MT is a gear reduction starter ideal for heavy duty truck and off highway applications. The drive has an electrical soft start that rotates the pinion for proper ring gear engagement before cranking, minimizing tooth abutment related damage. The sealed solid link solenoid eliminates contact welding in low system voltage situations, providing enhanced reliability. Sealed noseless configuration minimizes debris accumulation and contamination reducing maintenance expense.
The 41MT is a straight drive starter for heavy duty applications rated at 5.0 kW for 12 volt applications and 7.0 kW for 24 volt applications.
The 42MT is a straight drive starter for heavy duty applications available in 12 volt and 24 volt configurations. The 42MT features a Semi Solid Link solenoid and optional Over-Crank Protection.
The 50MT is a straight drive starter for heavy duty and industrial applications. The 50MT is available in 12, 24, 32, and 64 volt models and can start engines with displacement up to 29.5 liters.
The 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 to extend starter life. Watch the animation below to see how it works.
OCP technology is a built-in circuit breaker that protects the starter from thermal damage and automatically resets at a safe operating temperature. OCP protects the starter in adverse starting conditions, such as cold weather cranking, lower battery capacity, high-starting circuit resistance, or operator misuse. OCP is an option available today on 41MT™, 42MT™, 39MT™.
