The 986813 clutch bearing (also known as the Cummins 5T/6T clutch release bearing) is a genuine SINOTRUK HOWO component engineered to provide smooth, reliable clutch disengagement in heavy‑duty trucks. As a critical element of the trusted Sinotruk howo parts family, this bearing ensures precise actuation of the clutch mechanism, reducing pedal effort and preventing premature wear of the pressure plate and friction disc. Manufactured from high‑quality bearing steel with a sealed, maintenance‑free design, the 986813 unit withstands the extreme axial loads and high rotational speeds encountered in mining, construction, and long‑haul applications. Investing in this authentic component guarantees smooth gear shifts, extended clutch life, and reliable performance.

The 986813 clutch bearing features a precision‑ground inner race and a robust outer race made from high‑carbon chromium steel (100Cr6) that ensures exceptional wear resistance and dimensional stability. The bearing incorporates a high‑temperature grease that remains effective even under prolonged heat exposure, and double‑lip seals protect against contamination from dust and moisture. Its self‑aligning design compensates for minor misalignments between the clutch fork and pressure plate, ensuring even load distribution and long service life.
Each 986813 bearing is 100% tested for noise and vibration, and its radial clearance is precisely controlled to guarantee smooth rotation. The bearing is pre‑greased and sealed for life, eliminating the need for periodic maintenance. It is designed to handle axial loads up to 12 kN and operate at speeds matching the engine’s maximum RPM. This rigorous quality control ensures that the bearing will provide reliable performance for hundreds of thousands of kilometers.

The 986813 clutch bearing is a direct OEM replacement used in Howo trucks equipped with Cummins 5T and 6T transmissions. It is mounted on the clutch release fork and engages the diaphragm spring fingers of the pressure plate, allowing smooth clutch disengagement when the pedal is depressed. This bearing is critical for the longevity of the entire clutch system, as any failure can lead to clutch drag, hard shifting, and accelerated wear of the friction disc.
In heavy‑duty applications such as mining, logging, and on‑highway hauling, the clutch bearing is subjected to constant axial loads and vibration. The genuine 986813 bearing is engineered to withstand these conditions, providing consistent performance and long service life. It is also compatible with various PTO configurations that rely on clutch engagement.
When replacing the clutch bearing, always inspect the clutch fork and pivot point for wear. Apply a thin film of high‑temperature grease to the bearing contact surface (if specified) and ensure the bearing slides freely on the sleeve.
Correct installation of the 986813 bearing is critical to ensure proper clutch function and long service life. Follow these steps:
Remove the transmission and clutch assembly. Clean the release fork and guide sleeve thoroughly. Inspect the fork pivot for wear; replace if necessary.
Apply a thin film of high‑temperature grease to the sleeve. Slide the new bearing onto the sleeve, ensuring it moves freely. Attach the retaining clip. Reinstall the clutch and transmission.
Adjust clutch pedal free play according to the service manual. Start the engine and test clutch engagement for smoothness and absence of noise.
A worn clutch bearing can cause noise and shifting difficulties. Common signs that replacement is needed include:
If any of these symptoms are observed, immediate replacement with a genuine 986813 bearing is recommended. Continuing to operate with a worn bearing can damage the pressure plate fingers and lead to premature clutch failure.
Precision‑ground races and balanced components ensure quiet, vibration‑free rotation, reducing driver fatigue and improving shift quality.
High‑quality steel and sealed lubrication protect against wear and contamination, significantly extending the bearing’s lifespan.
Manufactured to original specifications, the 986813 bearing guarantees perfect fitment and reliable performance, eliminating guesswork and installation issues.
To maximize the service life of your 986813 clutch bearing, follow these best practices:
By adhering to these guidelines, you ensure that the 986813 bearing performs optimally throughout its intended service interval.
Aftermarket clutch bearings are often made from lower‑grade steel with poor heat treatment and inadequate seals, leading to premature noise, roughness, and failure. The genuine 986813 is manufactured to the exact specifications of the original equipment, using premium bearing steel and precision grinding. Each bearing is tested for noise, vibration, and seal integrity, guaranteeing that it will perform exactly as the original part.
By choosing authentic SINOTRUK HOWO parts, you protect your investment and ensure your truck maintains its reliability and resale value. The Sinotruk howo parts catalog includes a full range of clutch and driveline components engineered for maximum durability. For fleet managers and owner‑operators who demand the best, the genuine 986813 is the only responsible choice.
The 986813 clutch bearing is used across a wide range of Howo models equipped with Cummins 5T and 6T transmissions. It fits many T7H, A7, and classic Howo‑7 trucks. Always verify the transmission model and release fork design using the service manual.
Each 986813 is individually packaged in a protective box with foam inserts. The package includes the bearing only; the retaining clip may need to be ordered separately if not included.
Production of the 986813 takes place in IATF 16949 certified facilities, using automated grinding and assembly with in‑process gauging. Statistical process control ensures that dimensional variations are kept to a minimum. Every batch is accompanied by a material certificate and noise test report, guaranteeing that the bearings delivered are identical to those fitted on new Howo trucks at the factory.
