As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM-grade roller set as a direct replacement for the original factory components. The SPKM0000000735 flywheel rollers provide smooth, low-friction rotation between the flywheel and the crankshaft, ensuring efficient power transfer, reduced vibration, and extended driveline life. Manufactured from high-quality bearing steel with precision-ground surfaces, controlled heat treatment, and a corrosion-resistant finish, these rollers deliver exceptional load-carrying capacity, wear resistance, and reliability under the extreme torque and operating conditions typical of heavy-duty truck applications.
The SPKM0000000735 engine flywheel rollers are a critical component for maintaining proper flywheel alignment and driveline smoothness. Worn or damaged rollers can lead to increased vibration, clutch chatter, and premature failure of the flywheel or crankshaft. This genuine OEM roller set restores smooth, reliable operation and ensures your HOWO truck performs at its best.
OEM direct replacement • High-quality bearing steel • Precision-ground surfaces • Heat-treated for durability • Corrosion-resistant finish
The SPKM0000000735 is a matched set of engine flywheel rollers designed for the driveline systems of SINOTRUK Howo A7, T7H, and other heavy-duty truck models. These rollers are installed between the flywheel and the crankshaft, providing a low-friction bearing surface that allows the flywheel to rotate smoothly while accommodating axial and radial loads. Their OEM-grade construction precisely matches the original rollers’ dimensions, hardness, and load ratings, ensuring perfect fitment and reliable performance.
The rollers are manufactured from high-carbon chromium bearing steel (GCr15 or equivalent) with precision-ground cylindrical surfaces and controlled roller geometry. The material is heat-treated to achieve a uniform hardness of HRC 60-65 across all rollers, providing excellent wear resistance and fatigue strength. The surfaces are finished to a mirror-like quality to minimize friction and ensure smooth, quiet operation.
The SPKM0000000735 set is carefully matched to ensure consistent roller diameter and roundness, promoting even load distribution and reducing the risk of premature wear. The rollers are also treated with a corrosion-resistant phosphate or zinc coating to protect against moisture and contamination from driveline fluids.
Common symptoms of failing flywheel rollers include excessive driveline vibration, clutch chatter, unusual noises during clutch engagement, and visible wear or pitting on the roller surfaces. Replacing worn rollers with the SPKM0000000735 set restores smooth flywheel rotation and protects the clutch and transmission from costly damage.
Whether you’re performing a clutch replacement, flywheel resurfacing, or major driveline overhaul, the SPKM0000000735 Engine Flywheel Rollers offer the quality, precision, and durability that SINOTRUK Howo professionals demand.
The SPKM0000000735 engine flywheel rollers are specifically designed for SINOTRUK Howo A7 and T7H series trucks, as well as other heavy-duty models equipped with WD615, D10, D12, and MC series diesel engines. They serve as a direct replacement for the original flywheel rollers and are compatible with all driveline configurations that use this specific roller size and specification.
These rollers are essential for applications involving heavy loads, frequent clutch engagement, and demanding operating conditions, such as long-haul transport, construction, mining, and heavy hauling. In these environments, the flywheel rollers are subjected to high torque loads, vibration, and thermal cycling. The SPKM0000000735 set is engineered to provide consistent, low-friction rotation, reducing wear on the flywheel and crankshaft, and ensuring smooth clutch operation.
When replacing flywheel rollers, it is recommended to inspect the flywheel, pilot bearing, and clutch assembly for wear or damage. The SPKM0000000735 rollers are designed to work with the factory flywheel and crankshaft, ensuring proper clearance and load distribution. They are compatible with both single and dual-disc clutch configurations.
For fleets with multiple HOWO trucks, this roller set standardizes driveline maintenance, simplifying parts inventory and ensuring the correct component is available for scheduled service or emergency repairs. Always verify the roller dimensions and quantity on your specific flywheel to confirm compatibility, though the SPKM0000000735 is the standard roller set for the majority of A7 and T7H applications.
Replacing the SPKM0000000735 engine flywheel rollers is a complex procedure that requires advanced mechanical skills, specialized tools, and careful attention to cleanliness. This work should be performed by qualified heavy-duty mechanics with experience in driveline and clutch systems. Begin by safely removing the transmission and clutch assembly to access the flywheel.
Remove the flywheel from the crankshaft, taking care to note the orientation and the position of any dowel pins. Clean the flywheel and crankshaft surfaces thoroughly with a solvent and lint-free cloth, removing all old lubricant, debris, and corrosion. Inspect the flywheel for wear or damage – if the flywheel surface is scored or warped, it should be resurfaced or replaced.
Carefully remove the old rollers from the flywheel, noting their arrangement and the condition of the roller pockets. Clean the roller pockets with a suitable brush and solvent to remove any debris. Install the new SPKM0000000735 rollers, ensuring they are properly seated in the pockets and that they rotate freely without binding.
Apply a thin coat of high-temperature grease to the rollers and the flywheel contact surfaces to ensure smooth rotation and reduce wear. Reinstall the flywheel onto the crankshaft, torqueing the retaining bolts to the manufacturer’s specified value. Reinstall the clutch assembly and transmission, following the recommended torque procedures for all fasteners.
For maintenance, regularly inspect the driveline for unusual vibrations or clutch chatter, which may indicate roller wear. The SPKM0000000735 rollers are designed for long service life, but regular inspections during clutch replacements are recommended to ensure optimal driveline performance and prevent costly damage.
The SPKM0000000735 engine flywheel rollers are manufactured in an ISO 9001-certified facility using advanced grinding, heat-treatment, and quality control processes. The bearing steel is sourced from certified mills and undergoes chemical analysis to confirm its composition and mechanical properties. Each roller is precision-ground to exacting tolerances to ensure consistent dimensions and surface finish.
Every roller undergoes a comprehensive series of quality checks, including dimensional verification, hardness testing, and surface finish inspection. The rollers are inspected for roundness and straightness to ensure smooth operation. Random samples from each batch are subjected to fatigue testing and load capacity verification to confirm long-term reliability.
The corrosion-resistant coating is applied using advanced techniques to ensure excellent adhesion and protection against rust and contamination. Each set is packaged in a clean, protective environment to maintain surface integrity.
