The OEM gear features CNC-ground involute teeth with surface finish below Ra 0.8, reducing friction and noise while improving oil film retention under heavy loads. The 080V04505-5119 is engineered for zero-defect performance and absolute reliability, making it the first choice for professional rebuilds.
Through carburizing and quenching, this gear achieves a hard core with a wear-resistant surface (60-64 HRC), ensuring exceptional resistance to pitting and scoring even in extreme duty cycles.
This intermediate gear is not just another spare part; it is the heart of your HOWO/Sitrak transmission synchronizer system. Designed to perfectly transfer motion between the input shaft and the main gear cluster, this gear reduces stress concentrations through its optimized root fillet design. Real-world tests show that vehicles equipped with this OEM-grade component (080V04505-5119) experience 18% less backlash and noticeably smoother gear engagements, translating to lower driver fatigue and reduced clutch wear.
Rated for engines up to 600 HP, the gear handles sudden shock loads with its ductile core, preventing catastrophic tooth fracture. For extreme conditions, 080V04505-5119 proves its worth every mile, delivering consistent performance under the heaviest loads.
With superior wear resistance, this gear often outlasts standard aftermarket alternatives by 40%, reducing costly downtime and maintenance frequency.
One of the standout features of this gear is its universal compatibility with a wide range of HOWO and Sitrak models, including the popular A7, T7H, and C7H series. It is manufactured under strict ISO 9001 and IATF 16949 quality management systems, ensuring that every batch meets the same stringent factory specifications as the original equipment.
Manufactured to original blueprints, ensuring zero clearance issues and perfect alignment with adjacent bearings and shafts. Always verify that your replacement is 080V04505-5119 for exact fitment, as this number guarantees the latest design revision.
Designed for modern drivetrains, providing the ideal tooth profile to maximize fuel efficiency while delivering robust pulling power.
When replacing a worn-out gear, many workshops overlook the importance of helix angle and dynamic balance. This component (080V04505-5119) undergoes high-speed dynamic balancing (G2.5 grade) to eliminate vibrations at operational RPMs. This balancing, coupled with isotropic superfinishing, reduces operating temperatures by up to 12°C compared to standard alternatives, directly contributing to longer oil life and cooler transmission operation.
Always preheat the gear to 80°C before pressing onto the shaft. Install with the marked side facing the thrust washer for correct axial play.
Use API GL-5 80W-90 oil. Replace lubricant every 40,000 km. Inspect the gear during each filter change for unusual wear or pitting.
Proper torque settings are critical when securing the retaining nut – factory recommended torque is 450-480 Nm. Using a digital torque wrench ensures preload on tapered roller bearings stays within tolerance, preventing premature failure of the intermediate gear assembly. Many fleets report that after switching to this genuine gear (080V04505-5119), transmission overhaul intervals extended from 300,000 km to over 450,000 km – a clear testament to its superior metallurgy and precise manufacturing.
This gear directly replaces older revision parts with similar OEM numbers (e.g., 080V04505-5118 and -5120), offering an improved tooth profile. It is fully compatible with HOWO 6×4 and 8×4 chassis, as well as Sitrak heavy-duty tractors equipped with MC11 and MC13 engines. For workshop managers, keeping this part in stock ensures you can handle sudden breakdowns with minimal lead time, keeping customers’ trucks on the road. Cross-reference always points to 080V04505-5119 as the direct upgrade, which simplifies inventory management.
Each gear undergoes 100% non-destructive testing (NDT) using magnetic particle inspection. Dimensional accuracy verified with CMM to within 0.01mm.
Arrives in anti-corrosion VCI paper, sealed in heavy-duty carton with foam inserts, ensuring pristine condition upon arrival.
In recent field studies, trucks using this intermediate gear showed a 6% improvement in drivetrain efficiency due to reduced parasitic losses from the gear mesh. This translates to tangible fuel savings over the vehicle’s lifetime. Additionally, the gear’s unique anti-wear additive coating provides a sacrificial layer that protects the base material during boundary lubrication, making it ideal for both on-highway and off-road applications where shock loads are common.
Choosing the right intermediate gear is about investing in the long-term health of your powertrain. This gear offers a perfect balance of toughness, precision, and durability. With advanced heat treatment and rigorous quality checks, it minimizes the risk of secondary damage to the transmission housing and adjacent gears. Whether you’re a fleet owner looking to standardize spare parts inventory or a mechanic who demands the best, this component (080V04505-5119) sets the benchmark for excellence.
Original equipment quality. Engineered for extreme durability. Backed by rigorous testing.
Trusted by workshops worldwide. The definitive choice for professionals.
This intermediate gear is more than a component; it’s a commitment to operational excellence. When you install it, you are future-proofing your transmission against inferior metallurgy pitfalls—such as spalling, galling, and premature tooth wear. Every time you shift, the gear works tirelessly to ensure smooth power flow from engine to wheels. Its robust construction absorbs torsional vibrations, protecting synchronizers and bearings from excessive stress.
Moreover, this gear is designed with serviceability in mind. Generous chamfers and lead-in radii make installation easier and safer, reducing the risk of nicks or burrs during assembly.
