Detailed Component Overview of Shacman WP12 Engine Block Group
Cylindrical pin — A precision-ground cylindrical pin that ensures accurate alignment and positioning of engine components. Manufactured from high-strength alloy steel, it provides exceptional shear resistance and maintains dimensional stability under thermal cycling.
Assembled Sealing Washer — This pre-assembled washer combines a metal retainer with an elastomeric sealing element. It delivers a reliable, leak-free seal around threaded connections, effectively preventing oil and coolant seepage in high-vibration environments.
Hexagon Screw Plug — A robust hexagonal-head plug designed for secure closure of engine oil galleries and coolant passages. Its precision threads and hardened surface ensure a tight fit and easy serviceability using standard hex tools.
O-ring — Manufactured from high-grade nitrile rubber, this O-ring provides a dependable static seal between mating flanges. It resists oil, fuel, and temperature extremes, maintaining its elasticity and sealing performance over extended service intervals.
Cylinder Liner — A replaceable wear sleeve that forms the combustion chamber boundary. Precision-honed to exact tolerances, it offers a durable surface for piston ring travel, reducing friction and extending the engine’s overhaul life.
Hexagon Flange Bolt — Featuring an integrated flange for enhanced load distribution, this bolt provides secure clamping of engine components. Its thread-locking design and high-grade steel construction resist loosening from vibration and thermal expansion.
Inner Hexagon Socket Head Cap Screw — A high-tensile socket head screw with an internal hex drive. Ideal for confined spaces, it enables precise torque application and provides a flush, secure fastening solution for critical engine joints.
Engine Block Assembly — The central structural foundation of the WP12 engine. This high-pressure die-cast assembly houses the cylinder bores, coolant jackets, and main bearing supports, providing the rigidity and accuracy essential for optimal engine function.
Back-up Block — A robust reinforcement component that provides additional structural support to the engine block. It enhances overall rigidity, reduces flex under heavy loads, and contributes to the long-term durability of the power unit.
Pressure Sensor — A precision electronic sensor that monitors engine oil or fuel pressure in real time. It delivers accurate signals to the engine control unit, enabling adaptive fuel management and protecting the engine from pressure-related faults.
Sealing Washer — A high-performance flat washer with an integrated sealing lip. It prevents fluid migration around fastener heads and is designed to withstand high clamp loads, temperature swings, and aggressive chemical environments.
