The EVB Clamping Plate Assembly is a precision-engineered component that plays a vital role in the Exhaust Valve Brake (EVB) system of the Sitrak C7H engine. This assembly ensures reliable actuation of the exhaust valves during engine braking, providing additional stopping power and reducing wear on the service brakes.
This high-quality EVB Clamping Plate Assembly kit includes the Hexagon Flange Bolt Q186-M10X60-10.9-MAN183-B1, EVB Clamping Plate, Hexagon Nut M14X1, and Adjusting Screw. Each component is manufactured to exact OEM specifications, ensuring a perfect fit and reliable operation within the EVB system.
The EVB Clamping Plate Assembly is designed to withstand the high forces and temperatures encountered during engine braking. The clamping plate securely holds the EVB actuator mechanism, while the adjusting screw allows precise calibration of the valve lift. The high-strength fasteners ensure that all components remain securely fastened, even under extreme vibration and thermal cycling.
For complete technical specifications and ordering details, please refer to the official Sinotruk Catalog, which provides comprehensive information on all available variants and compatible truck models for the EVB Clamping Plate Assembly.
Whether you are rebuilding an EVB system or performing routine maintenance, this EVB Clamping Plate Assembly delivers factory-quality components and a straightforward installation. This EVB Clamping Plate Assembly is the definitive choice for operators who demand reliable engine braking performance and long component life.
This high-strength flange bolt is a critical fastener in the EVB Clamping Plate Assembly, securing the clamping plate to the cylinder head. With a nominal diameter of M10 and a length of 60mm, it provides the necessary clamping force to hold the EVB mechanism in place. The bolt is manufactured to grade 10.9 strength, ensuring it can withstand the high tensile loads and thermal stresses encountered during engine braking. The integrated flange eliminates the need for a separate washer, simplifying installation and ensuring even load distribution. The MAN183-B1 specification guarantees compatibility with the Sitrak C7H engine, and the zinc-nickel coating provides excellent corrosion resistance, making it suitable for use in harsh operating environments.
This is the central component of the EVB Clamping Plate Assembly, a precision-stamped steel plate that holds the EVB actuator and provides a mounting interface for the adjusting screw and nut. The plate is made of high-carbon steel with a heat-treated finish to resist wear and deformation. It features accurately positioned holes for the mounting bolts and a recessed area for the adjusting screw. The plate’s design ensures that the EVB mechanism is held securely, preventing any movement that could affect valve timing or braking performance. Its compact size and low weight contribute to the overall efficiency of the engine brake system, while the durable construction guarantees a long service life even under continuous heavy-duty use.
This M14x1 hexagon nut is used in conjunction with the adjusting screw to precisely set the EVB valve lift. Manufactured from quenched and tempered steel with a fine-pitch thread, it provides accurate adjustment and reliable locking. The nut features a flanged design that distributes clamping pressure evenly, preventing damage to the clamping plate. Its zinc-plated finish ensures corrosion resistance, while the precise thread geometry allows for smooth, consistent adjustment. In the EVB Clamping Plate Assembly, this nut plays a crucial role in setting the correct valve clearance, which is essential for optimal engine braking performance and noise control.
This precision-ground adjusting screw is the fine-tuning element of the EVB Clamping Plate Assembly. It is used to adjust the lift of the exhaust valves during EVB operation, directly influencing the amount of engine braking power. The screw is made of hardened tool steel with a precise metric thread and a hexagon socket for easy adjustment. Its tip is specially contoured to interface with the valve bridge, ensuring accurate force transmission. The screw’s locking mechanism prevents it from vibrating loose under operating conditions, maintaining the adjusted setting over time. In the EVB Clamping Plate Assembly, the adjusting screw allows technicians to calibrate the EVB system to the manufacturer’s specifications, ensuring consistent and effective engine braking.
The EVB Clamping Plate Assembly includes an adjusting screw that allows precise setting of the exhaust valve lift. This ensures that the engine brake delivers maximum stopping power while maintaining smooth operation, reducing driver fatigue and service brake wear.
This EVB Clamping Plate Assembly includes all necessary components – clamping plate, high-strength bolt, adjusting nut, and screw – for a complete replacement or overhaul. No need to source individual parts, saving time and ensuring compatibility.
All components of the EVB Clamping Plate Assembly are manufactured from heat-treated steel with corrosion-resistant coatings, capable of withstanding the extreme temperatures and high-pressure exhaust gas environment of the engine brake system.
The EVB Clamping Plate Assembly is manufactured to the exact OEM specifications, guaranteeing a perfect fit on the Sitrak C7H engine. The included fasteners are pre-sized and matched to the original hardware, eliminating fitment issues and ensuring reliable operation.
