This DELCO Remy 42MT starter motor is designed for heavy-duty diesel applications that require stable, high-torque cranking performance. It operates on a 24V electrical system, delivers 8.0KW of starting power, and uses a 13-tooth pinion gear with clockwise rotation, supporting smooth and consistent engine engagement under demanding working conditions.
The starter is applied on Case 40LC and 40R crawler and industrial equipment equipped with Detroit Diesel 4-53 engines from 1986 production. Its mounting configuration, electrical interface, and drive system are developed to match original equipment installation requirements, allowing direct replacement without structural modification.
This unit is fully compatible with multiple original and cross-reference part numbers, including WAI 6381N, LESTER 6381, and DELCO references 10461026, 10461137, 1990435, 19923923, and 1993786, supporting efficient parts sourcing and maintenance operations across service networks.
Manufactured by SANYOU, this starter motor is produced using 100% brand-new quality components and precision-controlled assembly processes. Internal components are developed to align with original factory structural and performance standards, supporting stable torque output, reliable service behavior, and consistent electrical performance. The manufacturer states that the operating performance and service life are comparable to genuine original factory starter units, providing dependable starting capability for long-term heavy-duty use.
