The hydraulic pump group is engineered to deliver high flow rates and pressures, supporting power steering, hydraulic lifts, and other auxiliary functions. Its robust construction ensures consistent performance, even under heavy loads and high temperatures.
The group is supplied with all necessary hardware, including the hexagon flange bolt, for a complete, hassle‑free installation. Detailed torque specifications are provided to ensure correct preload and long‑term reliability.
This hydraulic pump group is an essential component for maintaining vehicle hydraulic system performance. Regular inspection of the pump, bolts, and hydraulic fluid is recommended, and replacement of the entire group is advised if any signs of leakage, wear, or loose mounting are detected. Its genuine Shacman quality ensures that your vehicle continues to deliver reliable hydraulic power for all critical functions.
Hexagon Flange Bolt – A high‑strength fastener with an integrated flange that securely attaches the hydraulic pump to the engine block or mounting bracket. Manufactured from premium alloy steel, heat‑treated to grade 10.9, and coated with a zinc‑plated finish for exceptional corrosion resistance, this bolt provides consistent clamping force under severe vibration and thermal cycling. The integrated flange distributes the clamping load evenly across the mounting surface, preventing galling and eliminating the need for separate washers. Each bolt is supplied with a pre‑applied micro‑encapsulated thread‑locking compound to ensure it remains securely in place, even under the most demanding operating conditions. Its precise length and thread pitch are matched to the specific mounting holes, guaranteeing a perfect fit every time. This bolt is critical for maintaining the integrity of the hydraulic pump mounting system, preventing loosening that could lead to pump misalignment, belt damage, or hydraulic fluid leaks. Replacement is recommended if the bolt shows signs of thread damage, corrosion, or if the locking patch has been compromised. Proper torque application is essential, and detailed torque specifications are provided to ensure that the bolt is tightened to the correct preload, avoiding under‑tightening (which can lead to loosening) or over‑tightening (which can strip threads or damage the pump housing). This hexagon flange bolt is a direct replacement for the original factory component, ensuring identical strength and reliability. Its robust design and high‑quality materials make it an essential component for any WP12 hydraulic pump service or overhaul, providing the secure mounting needed for reliable hydraulic power delivery in heavy‑duty applications. The bolt’s flange design also simplifies installation, reducing assembly time and the risk of incorrect washer placement. With its superior corrosion resistance and locking features, this bolt ensures long‑term mounting integrity, contributing to the overall durability and safety of the vehicle’s hydraulic system.
