7. FAQ

Q: Is this starter motor a direct replacement for my Delco Remy 39MT?

Yes. The HD-850 is a direct, bolt-on replacement for the Delco 39MT, Bosch 0 001 208 005, and Mitsubishi M009T. It uses the same SAE J542 mounting flange and electrical connections.

Q: Can this starter handle extreme cold weather starting?

Absolutely. The high-torque planetary gear reduction system provides 1,500 Nm of cranking torque, which is sufficient to start most 12-15L diesel engines down to -40°F. We recommend using a block heater in sustained sub-zero conditions for optimal performance.

Q: What is the warranty policy?

We offer a 2-year / 200,000-mile warranty covering defects in materials and workmanship. The warranty is transferable if the vehicle is sold. Excludes damage from improper installation or modification.

Q: Do you offer bulk pricing for fleet operators?

Yes. We provide tiered discounts for orders of 10+ units. Contact our B2B sales team for a custom quote. Fleet managers in the ebbing auto parts indiana network receive priority pricing and expedited shipping.

Q: How do I verify the correct rotation direction?

Standard rotation is clockwise when viewed from the drive end (pinion side). If your application requires counter-clockwise rotation, please specify when ordering. We stock both configurations.

Q: What is the expected lifespan of this starter?

Under normal operating conditions (regional haul, 60,000 miles/year), the starter typically lasts 5-7 years. The brush life is rated for 80,000 starts, and the planetary gears are designed for the life of the unit.
