As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM‑grade clutch housing as a direct replacement for the original factory unit. The FG9804230158 housing ensures correct alignment of the clutch components, efficient heat dissipation, and reliable protection against contaminants, extending the service life of your clutch system.
Manufactured from high‑strength cast iron with precision‑machined mounting surfaces, the FG9804230158 3.5‑metric‑ton truck clutch housing provides a rigid, stable enclosure for the clutch disc, pressure plate, and release bearing. Its design incorporates optimized ventilation channels to promote airflow and reduce operating temperatures, minimizing the risk of clutch fade and component warpage under heavy loads.
OEM FG9804230158 • 3.5‑metric‑ton capacity • Cast iron construction • Precision machined • Direct OEM fit
The FG9804230158 is a heavy‑duty clutch housing designed specifically for 3.5‑metric‑ton capacity SINOTRUK Howo trucks, including popular models such as the Howo A7 and T7H series. This housing serves as the protective enclosure for the clutch assembly, mounting directly to the engine flywheel housing and providing a precise interface for the transmission bell housing.
The FG9804230158 clutch housing is manufactured from high‑grade cast iron (GG‑25 equivalent) using a precision‑molding process that ensures uniform wall thickness and structural integrity. The casting is heat‑treated to relieve internal stresses, then CNC‑machined on all critical surfaces, including the flywheel mounting face, transmission pilot bore, and dowel pin locations, guaranteeing perfect alignment and concentricity.
This housing incorporates strategically placed ventilation ribs and a large inspection window (covered by a removable dust plate) to allow for clutch wear inspection without full disassembly. Its internal geometry is optimized to accommodate the clutch disc, pressure plate, and release bearing, while providing adequate clearance for the clutch fork and pivot ball.
Common signs of a damaged clutch housing include cracks, stripped mounting threads, or warped mating surfaces, which can lead to clutch misalignment, excessive vibration, and premature component failure. Replacing a faulty housing with the FG9804230158 restores proper alignment, eliminates vibration, and extends the service life of your clutch system. This OEM‑spec housing is the ideal choice for clutch overhauls and transmission repairs.
Whether you are rebuilding a clutch assembly or replacing a damaged housing, the FG9804230158 3.5‑metric‑ton truck clutch housing offers the strength, precision, and durability that SINOTRUK Howo professionals demand.
The FG9804230158 clutch housing is purpose‑built for SINOTRUK Howo trucks with 3.5‑metric‑ton front or rear axle capacities, commonly found in A7 and T7H series models, as well as other medium‑duty chassis using this clutch housing configuration. It is a direct OE replacement and is fully compatible with factory flywheel housings, transmissions, and clutch components.
This housing is ideal for applications that require reliable clutch protection and heat management, such as regional distribution, construction support, and agricultural hauling. In these environments, the clutch housing is subjected to thermal cycling, vibration, and potential impact from road debris. The FG9804230158 is engineered to maintain structural integrity and precise alignment, reducing the risk of clutch chatter and premature wear.
When replacing the clutch housing, it is important to inspect the flywheel housing mounting surface, transmission pilot bearing, and all fasteners for wear or damage. The FG9804230158 housing is designed to work with the factory components, ensuring proper fit and alignment. It is compatible with both standard and heavy‑duty clutch configurations that use the 395 mm outer diameter housing.
For fleet operators, standardizing on the FG9804230158 simplifies parts inventory and ensures that the correct housing is readily available for scheduled services or emergency repairs. Always verify the clutch size and transmission type on your specific truck to confirm compatibility, though the FG9804230158 is the standard clutch housing for the majority of 3.5‑ton A7 and T7H applications.
Replacing the FG9804230158 clutch housing is a complex procedure that requires mechanical expertise and appropriate lifting equipment. This work should be performed by qualified technicians with experience in heavy‑duty truck clutch and transmission systems. Begin by safely raising the vehicle and supporting the transmission, then remove the transmission and clutch assembly to access the housing.
Before removing the old housing, thoroughly clean the area and disconnect any mounting bolts, dowel pins, and ground straps. Carefully detach the housing from the flywheel housing, taking care not to damage the mating surfaces. Inspect the flywheel housing for cracks or wear, and check the dowel pins for damage.
Install the new FG9804230158 housing by aligning it with the dowel pins and seating it flush against the flywheel housing. Insert and torque all mounting bolts to the manufacturer’s specification in a criss‑cross pattern to ensure even clamping. Reinstall the clutch assembly, transmission, and all associated components, ensuring proper alignment and clearance.
After installation, perform a thorough road test to confirm smooth clutch operation with no unusual vibrations, noises, or fluid leaks. For maintenance, periodically inspect the housing for cracks, corrosion, or loose bolts. Clean the ventilation passages and inspection window to ensure proper airflow. Replace the housing as part of a full clutch overhaul to ensure optimal performance and reliability.
The FG9804230158 clutch housing is manufactured in an ISO 9001‑certified foundry using advanced molding, heat‑treatment, and CNC machining processes. The cast iron is sourced from certified suppliers and undergoes chemical and mechanical testing to verify its composition, tensile strength, and hardness (min. 200 HB).
Each casting is radiographically inspected for internal porosity and stress cracks before machining. The CNC machining process maintains tolerances of ±0.05 mm on all critical dimensions, including the pilot bore, mounting face flatness, and bolt hole positions. The housing is then phosphate‑coated to provide corrosion resistance and a paint‑ready surface.
Every housing undergoes a final dimensional inspection using CMM equipment, along with a torque‑retention test on the mounting threads. Random samples from each production batch are subjected to thermal cycling and vibration testing to simulate real‑world operating conditions, ensuring long‑term reliability.
We back the FG9804230158 with a comprehensive 12‑month warranty against material and workmanship defects. Our rigorous quality control ensures that every housing delivers the same fit, performance, and durability as the original factory component, giving you confidence in your clutch system’s integrity.
The FG9804230158 3.5‑metric‑ton Truck Clutch Housing is a vital component for maintaining proper clutch alignment, heat management, and protection in your HOWO truck. A damaged or warped housing can lead to clutch misalignment, excessive wear, and premature failure of the clutch disc, pressure plate, and release bearing.
