The clutch booster is the key to a light, consistent pedal feel and smooth engagement, but its performance depends entirely on a rock‑solid mounting bracket. The WG2229260016 BRACKET CLUTCH BOOSTER HOWO 371 from HOWO is engineered to provide an absolutely rigid, precisely aligned foundation for your clutch booster, ensuring consistent assist pressure and eliminating flex that leads to premature wear and erratic pedal feel. As a critical Howo/Sitrak truck parts component, this bracket is precision‑cast from high‑strength ductile iron, featuring reinforced gussets and fully machined mounting faces that guarantee a perfect, twist‑free fit every time. Whether you are replacing a cracked bracket or upgrading to the latest OEM specification, the WG2229260016 delivers factory‑grade rigidity, flawless booster geometry, and lasting durability – making it the definitive choice for professional workshops and fleet maintenance teams worldwide.
The WG2229260016 bracket is the structural linchpin of the clutch booster system. It holds the booster firmly to the transmission bell housing or firewall, ensuring that the pushrod aligns precisely with the clutch fork. Any flex, misalignment, or weakness in this bracket causes the booster to move, reducing its efficiency and leading to inconsistent clutch assist, increased pedal effort, and accelerated wear on the booster’s internal seals. HOWO has designed this bracket with a box‑section profile and strategically placed ribs that resist bending and torsion even under the highest hydraulic pressures. The precision‑machined mounting holes and dowel pin locations guarantee that the booster sits exactly in the factory position, eliminating the need for shims or adjustments. With the WG2229260016, you restore the original clutch feel, reduce driver fatigue, and extend the life of the entire clutch actuation system.

The WG2229260016 is produced using advanced green‑sand casting, which ensures a dense, porosity‑free structure and consistent mechanical properties. The ductile iron grade GGG50 offers a minimum tensile strength of 500 MPa and excellent impact resistance, making it ideal for the highly loaded clutch booster application. The bracket’s geometry has been optimized using finite element analysis (FEA) to distribute stress evenly and eliminate weak points.
After casting, the bracket undergoes a shot‑blasting operation to remove scale, followed by precision CNC machining of all mounting faces and hole locations. The flatness of the booster mounting face is held to within 0.05 mm, ensuring that the booster is not subjected to any bending moment when bolted down. The threaded holes are formed with thread‑forming taps to ensure consistent clamp load and resistance to vibration loosening. Each bracket is inspected for dimensional accuracy, hardness, and surface integrity, guaranteeing that the WG2229260016 provides a flawless fit and unwavering performance for the life of your vehicle.
The WG2229260016 is specifically designed for HOWO 371‑series trucks, as well as T7H, A7, and other models equipped with the MC11/MC13 engine and the corresponding clutch booster system. It mounts directly to the transmission housing and provides the exact orientation and offset for the WABCO or ZF clutch boosters used in these vehicles. The bracket is also compatible with many Sinotruk trucks that share the same chassis and powertrain architecture.
To confirm fitment, always verify the OEM number on your existing bracket. If it matches WG2229260016, this component will integrate seamlessly. Keeping this bracket in your spare parts inventory ensures that you can quickly address booster misalignment or bracket fatigue, minimising downtime and preserving the smooth, predictable clutch operation that drivers rely on.

Replacing a worn or cracked bracket with the WG2229260016 immediately restores the original booster geometry and rigidity. The result is a consistent, light clutch pedal feel throughout the entire travel range, reducing driver effort and fatigue during long shifts. The elimination of bracket flex also extends the life of the booster internal seals and the clutch slave cylinder, as they are no longer subjected to side loads and vibration.
The precise alignment ensures that the pushrod engages the clutch fork at the correct angle, reducing wear on the fork pivot and the release bearing. This translates to fewer clutch adjustments and longer intervals between overhauls. For fleet operators, the reliability and longevity of a genuine HOWO bracket reduce maintenance costs and improve driver satisfaction. By investing in the WG2229260016, you ensure that your clutch system operates as designed – smoothly, efficiently, and durably.
Installing the WG2229260016 bracket is a straightforward procedure for a qualified technician. Begin by safely lifting the vehicle and supporting it on stands. Remove the clutch booster and the old bracket, noting the orientation and any spacers that may have been used.
Clean the transmission housing and the booster mounting surfaces thoroughly. Install the new bracket using the original bolts (or new grade 10.9 hardware), torquing them evenly to the manufacturer’s specification in a cross‑pattern. Reattach the clutch booster, ensuring the pushrod engages the fork correctly. Adjust the booster pushrod length to the specified clearance. Bleed the clutch hydraulic system and test the pedal for smooth operation and correct free play. Re‑torque all fasteners after a test drive. With proper installation, the WG2229260016 will provide years of reliable service.
Pro Tip: When replacing the bracket, always use new bolts and self‑locking nuts. Old fasteners can stretch and lose clamping force. The WG2229260016 is designed to work with grade 10.9 hardware; ensure correct torque to avoid distortion of the bracket or booster.
Genuine HOWO components are engineered to the highest standards, and the WG2229260016 Clutch Booster Bracket is no exception. Aftermarket brackets often use lower‑grade iron, lack proper ribbing, or have inaccurate hole locations, leading to flex, misalignment, and premature failure. HOWO’s bracket is manufactured using the same materials and processes as the original equipment, guaranteeing a perfect fit and reliable performance.
By choosing the WG2229260016, you benefit from HOWO’s rigorous validation, including vibration fatigue testing, thermal cycling, and salt spray corrosion testing. This ensures that the bracket maintains its structural integrity under the most demanding conditions. Moreover, genuine parts are backed by a comprehensive warranty and supported by HOWO’s global network, giving you confidence in your purchase.
