This DELCO Remy 50MT starter motor is developed for large-displacement diesel engines used in heavy construction, mining, and industrial machinery. It operates on a 24V electrical system and delivers 9.0KW of high-torque output, using an 11-tooth pinion gear and clockwise rotation to provide strong and stable engine cranking for high-compression power units.
The starter is widely used in Caterpillar heavy equipment platforms such as 3406, 3408, 3412, 3508, 3512, and 3516 engines, as well as Cummins K Series engines, including K38. Its structural design matches original mounting dimensions and electrical connection layouts, supporting direct installation during replacement or overhaul processes.
This model is compatible with a wide set of OEM and aftermarket reference numbers, including WAI 4930N, 3905N, and 8201091, as well as LESTER 4600 and 4930. It crosses to CASE part numbers 20-1297T91 and 462588C91, multiple Caterpillar references such as 0R4272, 0R5213, and 10R9815, and Cummins part numbers including 173184 and 3000576. It also aligns with a large group of DELCO Remy numbers, such as 10461057, 10461125, 10461381, and 1109222, allowing accurate identification across global service networks.
Manufactured by SANYOU, this starter motor uses 100% brand-new internal components and controlled assembly processes. Critical parts are built to match original factory technical standards, supporting stable electrical performance, consistent torque delivery, and long operational service cycles. The manufacturer states that both performance and service life are comparable to genuine original factory starters, providing dependable starting support for high-load industrial diesel equipment.
