24V 8KW Starter Motor for Dongfeng Cummins, Dongfeng Tianlong & Auman Heavy Trucks

I. Core Performance Advantages (Exclusive for 24V 8KW)

• High torque & fast starting: 8KW high power + 24V system delivers far higher torque than 12V models of the same power. Easily starts large-displacement, high-compression diesel engines (such as Cummins 6BT/6CT, Tianlong / Auman heavy trucks), with quicker and cleaner starts.

• Stable in low temperature & weak battery: Maintains approximately 85% rated torque at -25℃. 24V reduces circuit current, heat and voltage drop, resulting in significantly higher starting success rate than 12V systems when the battery is low.

• High efficiency & battery protection: Lower current at the same power reduces load on the battery and wiring, extending battery life. Starting current is about 15% lower than direct-drive models, saving power.

• Strong short-time overload capacity: Supports S2-30s short-time duty, with single start ≤ 30 seconds, meeting frequent start-stop and heavy-load starting demands of heavy trucks.

II. Structural & Durability Advantages (Heavy-duty Grade)

• Planetary reduction + soft engagement: Compact size, light weight and higher output torque. Smoother engagement greatly reduces risks of gear clash, tooth grinding and damage, protecting the flywheel and starter gear.

• High-strength key components:

• Drive gear: alloy steel + surface quenching, wear and impact resistant, service life increased by 30%+.

• Motor winding: high-temperature resistant enameled wire (class 180℃), adapts to high engine compartment temperatures.

• Solenoid switch: erosion-resistant contacts, reliable pull-in, reduced failures.

• Bearing: maintenance-free sealed bearing, suitable for high-frequency vibration and harsh road conditions.

• High protection & long service life: Protection grade IP54/IP55 (dustproof, splash-proof); standard starting cycles ≥ 50,000 times, far exceeding the national standard (20,000 times), ideal for long-haul, engineering, mining and other high-frequency start-stop applications.

III. Fit & Installation Advantages (For Dongfeng / Cummins / Auman)

• Original-equipment level precise matching: Interfaces, mounting holes, tooth count (11T/12T), rotation direction (CW) are fully compatible with Dongfeng Tianlong, Auman, Dongfeng Cummins 6BT/6CT/ISZ and other engines. Plug-and-play, no modification needed.

• Covers mainstream models: Fits Dongfeng Tianlong (210 HP / Euro 2 / 6BT), Auman heavy trucks, full series of Dongfeng Cummins. High parts universality, easy procurement and replacement.

• Smooth and low-noise operation: Optimized gear meshing and motor dynamic balance ensure low starting noise and vibration, improving driving and operating experience.

IV. Quality & After-sales Guarantee

• Strict quality control: Full-process testing (no-load / load / durability / high-low temperature tests) before delivery, meeting OEM standards for Cummins and Dongfeng.

• Reliable after-sales support: 12-month warranty provided by mainstream OEM / high-quality aftermarket suppliers, compatible with heavy-duty truck service networks for convenient maintenance and claims.

V. Application Summary

• Low-temperature and high-altitude areas

• Long-haul transportation, frequent start-stop, heavy-load starting

• Fleets and users with high requirements for reliability, service life and starting efficiency
