Heavy Duty Alternator

Delco Remy 38MT+™ Heavy Duty Gear Reduction Starter

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.
