FAQs – Delco Remy 28MT 12V Heavy-Duty Starter Motor Manufacturer
1. Is this 28MT starter a direct replacement for Lester 6590 / 6590N?
Yes. This starter motor is a direct OEM-equivalent replacement for Lester 6590 and 6590N, designed to match the same mounting dimensions, electrical specifications, pinion configuration, and engagement depth. No modification is required when replacing the original unit.
2. What engines and equipment commonly use the Delco Remy 28MT starter?
The 28MT starter motor is widely used on Perkins diesel engines, Oshkosh heavy-duty and specialty trucks, and Clark industrial and material-handling equipment. It is commonly found in fleet vehicles, forklifts, generators, and off-highway machinery operating on 12V systems.
3. What is the difference between a 28MT and a 50MT starter motor?
The main difference lies in voltage, power output, and starter system design.
The 28MT is a 12V gear-reduction (OSGR) starter with a 2.9kW output, optimized for medium to heavy diesel applications.
The 50MT is typically a 24V direct-drive starter with significantly higher power, used for very large engines such as Caterpillar D8–D10 class equipment. They are not interchangeable.
4. Is this starter suitable for fleet maintenance and commercial use?
Yes. This 28MT heavy-duty starter motor is built specifically for fleet maintenance, commercial vehicles, and industrial equipment, where reliability and repeatability are critical. It is commonly selected by fleet operators, engine rebuilders, and B2B aftermarket distributors.
5. What are the key technical features that matter for B2B buyers?
Key features include a 2.9kW gear-reduction system, 10-tooth pinion, 32mm pinion OD, 89mm engagement length, dry clutch design, and a 3-terminal solenoid. These specifications ensure high starting torque, reduced battery load, and consistent performance in demanding diesel environments.
6. Can this 28MT starter be used in international markets such as Africa, the Middle East, or South America?
Yes. The Delco Remy 28MT starter is widely used in Africa, the Middle East, South America, and Southeast Asia, especially in regions where Perkins engines and Oshkosh or Clark equipment are common. Its 12V system compatibility and robust design make it suitable for harsh operating conditions and remote service environments.
7. Is this starter motor OEM original or aftermarket?
This product is a brand-new, OEM-equivalent aftermarket starter motor, manufactured to meet or exceed original Delco Remy specifications. It is designed for interchangeability with OEM part numbers 10461460 and 10479604, without compromising fit or performance.
8. What should I verify before ordering this starter motor?
Before ordering, confirm the system voltage (12V), starter series (28MT), OEM or Lester reference number, pinion tooth count, and application equipment or engine model. Verifying these details helps avoid incorrect selection and installation issues.
9. Is this 28MT starter suitable for distributors and bulk purchasing?
Absolutely. This starter motor is commonly supplied for bulk orders, distributor stock, and project-based procurement. It is suitable for aftermarket distribution, engine overhaul programs, and fleet service contracts, where consistent specifications and long-term availability are required.
10. What quality standards and warranty are provided for this starter motor?
The starter motor is produced under an IATF 16949 and ISO 9001 certified quality system, ensuring consistent manufacturing quality. It is typically supplied with a 18 month commercial warranty, depending on order volume and application conditions.
