Maximize your drivetrain efficiency with the 4936134 CLUTCH DISK 38 40, a premium friction disc engineered for heavy-duty commercial vehicles. This clutch disk delivers exceptional torque capacity, smooth engagement, and outstanding wear resistance, making it the ideal choice for demanding haulage and construction applications. As a core component of genuine Howo/Sitrak truck parts, the 4936134 is manufactured to exacting OEM tolerances, ensuring a perfect fit and reliable performance in HOWO, Sitrak, and other compatible drivetrains. Whether you are replacing a worn clutch or upgrading your powertrain, this disk provides the durability and consistency needed to keep your fleet moving, reducing downtime and maintenance costs.
The 4936134 is a high-performance clutch disk that combines advanced friction materials with precision manufacturing to deliver superior torque transmission and pedal feel. The disk features a rigid, splined hub that provides a direct, backlash-free connection to the transmission input shaft, eliminating play and ensuring immediate power delivery. The friction linings are composed of a specially formulated organic compound with high metallic content, offering excellent heat dissipation and a stable coefficient of friction across a wide temperature range. This design minimizes judder and chatter during engagement, providing a smooth, progressive take-up that extends the life of the entire clutch system.
High Heat Tolerance – The friction material of the 4936134 can withstand continuous temperatures up to 400°C without fading, ensuring consistent performance during heavy hauling and hill starts.
Precision Balancing – Each disk is dynamically balanced to within tight tolerances, reducing driveline vibration and bearing stress, which contributes to smoother operation and longer component life.
Wear-Resistant Linings – The linings are cured under high pressure and temperature, resulting in a dense, durable surface that resists glazing and maintains friction coefficients over thousands of engagement cycles.
Smooth Engagement – The progressive friction curve of the 4936134 ensures that the clutch engages gradually, reducing shock loads to the transmission and driveline, which is critical for component longevity.
The 4936134 is designed to be a direct replacement for the original clutch disk in a wide range of HOWO and Sitrak models, including the HOWO T5G, T7H, and Sitrak C7H series. With its 38 spline count and 40 mm hub bore, it precisely matches the transmission input shaft specifications, ensuring a secure, wobble-free fit. The disk diameter and thickness are engineered to provide the correct clamping force and release travel, working seamlessly with the pressure plate and release bearing. By using the 4936134, you eliminate the risk of misalignment, premature wear, and clutch drag that can occur with generic aftermarket disks.
This clutch disk has been validated through extensive on-road testing with major fleet operators, proving its capability to handle the high torque outputs of modern diesel engines, often exceeding 2000 Nm. The 4936134 maintains consistent performance even under repeated stop-start cycles and heavy loads, making it a reliable choice for both urban delivery and long-haul applications. Its robust construction ensures that it can withstand the rigors of off-road construction sites and extreme weather conditions, providing years of dependable service.
Proper installation of the 4936134 is crucial for achieving optimal performance and longevity. Begin by cleaning the flywheel and pressure plate surfaces thoroughly to remove any oil, grease, or old friction material residue. Use a clutch alignment tool to center the disk on the flywheel pilot bearing, ensuring that the splines are perfectly aligned with the transmission input shaft. Tighten the pressure plate bolts evenly and in a crisscross pattern to the manufacturer’s recommended torque specification, typically around 25-30 Nm for M8 bolts. Always replace the release bearing and pilot bearing when installing a new clutch disk, as these components wear together.
After installation, a proper break-in period is essential for the 4936134. Avoid aggressive starts, heavy loads, and excessive clutch slipping for the first 500-800 km. During this time, the friction surfaces will bed-in, establishing an even contact pattern that enhances grip and prevents hot spots. Regular inspection of the clutch system, including hydraulic fluid levels and pedal free play, will help ensure that the 4936134 continues to perform at its best over its service life, which typically exceeds 200,000 km under normal operating conditions.
Every 4936134 clutch disk is manufactured in an IATF 16949-certified facility, adhering to the strictest automotive quality standards. The production process includes 100% inspection of critical dimensions, spline fit, and runout. Friction linings are tested for shear strength, hardness, and coefficient of friction using a dynamometer, simulating real-world engagement conditions. A random sample from each batch undergoes a 200-hour endurance test, where the disk is subjected to repeated high-torque engagement and disengagement cycles to verify its durability and resistance to wear.
In addition to bench testing, the 4936134 has been field-tested in collaboration with leading transport companies, logging millions of kilometers across diverse terrains. The feedback has been overwhelmingly positive, with users reporting fewer clutch failures and improved driver comfort. This rigorous quality assurance process ensures that every 4936134 you receive delivers the same outstanding performance as the original equipment, backed by our comprehensive warranty.
Fleet operators who prioritize reliability and cost-efficiency consistently turn to the 4936134 for their clutch replacements. Its proven track record of reducing clutch-related downtime, combined with its competitive price point, makes it an excellent investment. Many fleets have reported a 30% increase in clutch life compared to lower-quality aftermarket disks, translating into substantial savings over the lifetime of the vehicle. The 4936134 also contributes to improved fuel economy by ensuring efficient power transfer and reducing driveline losses.
Moreover, the availability of the 4936134 through our extensive distribution network ensures that you can always get the parts you need quickly, minimizing vehicle downtime. Its consistent quality and ease of installation make it a favorite among technicians, who appreciate the exact fit and clear installation marks.
