The Howo Reducer rear axle (OEM 712-35010-6326) is the heart of your truck’s final drive. It reduces rotational speed from the driveshaft while multiplying torque, ensuring your vehicle climbs gradients and hauls heavy payloads effortlessly. Manufactured from high-strength alloy steel with precision-hobbed gears, this reducer handles up to 2,600 N·m of input torque. Its advanced lubrication system minimises friction, lowering operating temperatures by up to 18% compared to conventional designs. Every unit undergoes strict dimensional and hardness testing, guaranteeing a service life exceeding 800,000 km under standard highway conditions.
Forged crown wheel & pinion – impact-resistant, noise-optimised tooth profile.
Double-taper roller bearings – absorb axial and radial loads with minimal deflection.
High-performance oil seals – prevent leakage and contamination even in muddy conditions.
100% interchangeability – direct replacement for original Howo/Sitrak axles without modification.

The Reducer rear axle 712-35010-6326 is engineered to seamlessly replace original units in Howo A7, Howo T7, Sitrak C7, and Sinotruk HD series. Its mounting dimensions mirror factory specifications, so no adapter plates or shims are required. The spline count (34 teeth) and pilot diameter (120 mm) ensure a perfect match with existing propeller shafts. For fleet managers, this translates to minimal downtime: a two-person team can complete the swap in under 4 hours using standard workshop tools. We recommend pairing this reducer with genuine Howo axle shafts and wheel hubs for maximum synergy.
Every batch of the 712-35010-6326 reducer undergoes a 72‑hour continuous load test on a dynamometer, simulating gradients up to 30% and alternating full‑throttle acceleration. The housing is pressure‑tested to 12 bar to verify sealing integrity. In field trials across Australian mine sites and Siberian winter routes, the reducer maintained stable performance from –35°C to +55°C. The gear teeth are micro‑peened to enhance surface fatigue resistance, reducing pitting risk by over 40% compared to standard finishes. With these proven credentials, the Howo Reducer rear axle is the go‑to choice for operators who demand zero unplanned stops.
Endurance – 1.2 million cycles under max torque
Cold start – seamless operation at -35°C with synthetic lube
To maximise the lifespan of your Reducer rear axle, follow these simple maintenance guidelines: change the gear oil every 60,000 km or 12 months (whichever comes first), using a high‑quality GL‑5 80W‑90 grade. Inspect the breather valve for clogging each oil change. Check the pinion seal and wheel‑end seals for leaks during regular pre‑trip inspections. With proper care, the reducer can exceed 1,000,000 km before any major overhaul. Our technical support team (available via the Howo/Sitrak parts portal) provides detailed service bulletins and torque specifications for all fastening elements.
Choosing the 712-35010-6326 Reducer rear axle from the trusted Howo/Sitrak parts network ensures you receive a component that matches the original equipment in every critical dimension. Counterfeit reducers often use substandard steel and imprecise gear cutting, leading to premature whine, bearing seizure, and catastrophic failure. Genuine parts feature a laser‑etched part number and batch code for full traceability. Moreover, they are backed by a comprehensive warranty and technical advisory. When you invest in authentic Howo running gear, you protect your asset’s resale value and keep your operating costs predictable. Explore the full range of Howo/Sitrak truck parts to complement your axle reducer with matching components.
Each Reducer rear axle 712-35010-6326 is carefully packaged in a heavy‑duty wooden crate with anti‑rust coating and moisture‑barrier film. The crate includes the reducer assembly, a breather tube, and a set of mounting bolts with pre‑applied thread locker. The part number is clearly marked on the housing and the outer carton to avoid confusion with similar models. For bulk orders (6+ units), we offer custom palletising and shipment tracking via major logistics partners. All shipments include a detailed packing list and certificate of conformance. Delivery lead times average 5–7 working days for most global destinations.
