Manufactured from high‑strength steel with a robust cast iron pedal arm, the assembly withstands the high forces of daily heavy‑duty truck operation without flexing or fatigue.
Zinc‑nickel plating combined with an e‑coat top layer provides outstanding rust resistance, ensuring the pedal assembly remains functional even in harsh road salt environments.
Pre‑calibrated return spring with optimized rate ensures consistent pedal return force and reduces driver fatigue, while preventing premature clutch release bearing wear.
This genuine clutch pedal assembly is the factory‑specified control interface for the following SINOTRUK Howo configurations:
The AZ9719230240 Clutch Pedal Assembly is manufactured using a combination of precision‑stamped steel components and a cast iron pedal arm, providing the strength needed for millions of actuation cycles. The main pivot incorporates sealed needle bearings that eliminate play and reduce friction, ensuring a smooth, precise pedal feel throughout the assembly’s service life. The pedal ratio of 4.5:1 is optimized for hydraulic clutch systems, providing the ideal balance between modulation precision and effort reduction.
In heavy‑duty truck applications, a worn or poorly designed clutch pedal assembly can lead to driver fatigue, premature clutch wear, and difficult gear engagement. The AZ9719230240 eliminates these issues by providing a precisely engineered interface that delivers consistent force transmission to the clutch master cylinder. Fleet data shows that replacing worn pedal assemblies with this genuine unit reduces clutch system failures by 54% and improves driver satisfaction scores significantly.
Installation of this pedal assembly follows standard heavy‑truck procedures. The assembly mounts to the firewall or pedal bracket using the factory mounting points with M10 bolts torqued to 45 Nm. The hydraulic line connection uses a standard M12 x 1.0 fitting. The integrated return spring is pre‑calibrated and does not require adjustment. Always replace the pedal assembly as a complete unit to ensure proper geometry and spring force.
Quality control for the AZ9719230240 includes 100% dimensional verification using coordinate measuring machines to ensure mounting bracket alignment, pedal arm geometry, and pivot bore concentricity. Each assembly undergoes force‑displacement testing to verify the pedal travel and return spring characteristics fall within specified tolerances. The bearings are tested for smooth rotation under load, and the corrosion protection coating thickness is verified using X‑ray fluorescence. Only assemblies passing these rigorous checks are approved for sale.
Environmental responsibility is embedded in the manufacturing process. The steel used contains 40% recycled content, and the zinc‑nickel plating facility operates with closed‑loop water treatment, recovering 98% of process water. The e‑coat process uses lead‑free, low‑VOC paint chemistry. Production scrap from stamping and machining is segregated and returned to steel mills for remelting, achieving a 97% material utilization rate. By choosing this genuine component, you support sustainable manufacturing practices without compromising on durability or driver comfort.
For fleet maintenance operations, the AZ9719230240 is available individually in protective packaging or in bulk packs of 5, 10, and 20 units. Each assembly is laser‑etched with the OEM part number and batch code for full traceability. Bulk orders are eligible for volume discounts and can be shipped directly from regional distribution centers. The packaging includes installation torque specifications and a QR code linking to a video guide for proper assembly and adjustment.
Field performance data collected from over 2,200 SINOTRUK Howo trucks operating in demanding environments—including mining in Chile, construction in Southeast Asia, and long‑haul in Europe—demonstrates that the AZ9719230240 clutch pedal assembly achieves a service life exceeding 1,400,000 kilometers with no reported mechanical failures. Fleet managers report that standardizing on this genuine assembly has eliminated pedal binding complaints and reduced clutch actuation system repairs by 62%.
When ordering, verify that the pedal assembly configuration matches your vehicle’s cab and hydraulic system. The AZ9719230240 is designed for standard SINOTRUK Howo manual transmission configurations with hydraulic clutch actuation. For applications with pneumatic clutch assist or different cab configurations, refer to the vehicle’s parts manual. Technical support is available through authorized dealer channels to assist with compatibility questions regarding specific vehicle configurations.
In summary, the AZ9719230240 Clutch Pedal Assembly represents the definitive driver control interface for SINOTRUK Howo trucks. Its robust construction, precision bearings, and optimized pedal geometry ensure smooth, consistent clutch engagement and reduced driver fatigue. By investing in this genuine component, you enhance drivability, protect the clutch system, and maximize driver comfort and safety.
During routine maintenance, inspect the AZ9719230240 pedal assembly for signs of corrosion, binding, or excessive free play. Replace if any pivot wear is detected or if the pedal fails to return fully.
Operate the pedal through full travel. Listen for squeaks or grinding. Check that the return spring fully resets the pedal. Any sticking or unusual noise indicates replacement is needed.
Aftermarket clutch pedal assemblies often use lower‑grade steel, plastic bushings instead of bearings, and inconsistent return springs, leading to premature wear, pedal slop, and binding. The genuine AZ9719230240 is manufactured from certified high‑strength materials with sealed needle bearings and a precision‑calibrated return spring that meets SINOTRUK’s durability standards. Counterfeit assemblies may appear similar but fail within months, causing difficult gear engagement and driver fatigue. With the OEM assembly, you receive a fully traceable, load‑tested component engineered for the life of your vehicle.
Preparation: Remove the old assembly. Clean mounting surfaces thoroughly. Inspect the clutch master cylinder pushrod for wear; replace if necessary. Apply anti‑seize to mounting bolts.
Securing: Position the new assembly and secure with M10 bolts torqued to 45 Nm. Connect the hydraulic line and torque to 20 Nm. Bleed the clutch system per manufacturer specifications.
After installation, verify full pedal travel and smooth operation. Check for any fluid leaks at the hydraulic connection. Re‑check torque after the first 500 operating hours.
Engineered to withstand 3 million full‑stroke cycles without wear beyond specification, validated by independent durability testing per SAE J4002.
Maintains smooth operation from -40°C in arctic conditions to +120°C under dash heat, ensuring consistent clutch feel across all climates.
Manufactured with 40% recycled steel content. Stamping and machining scrap is 100% recycled, reducing CO₂ emissions by 30% compared to conventional production.
