Power steering device – genuine HOWO complete hydraulic steering system kit for MAX 4X2
This Power steering device includes the gear, pump, all hoses, pipes, clamps, brackets, and every fastener. No need to source individual components; the entire hydraulic steering system is in one package.
All hydraulic parts in this Power steering device are tested to 180 bar, ensuring reliable operation under extreme loads. The high-pressure hose and seals guarantee leak-free performance.
The part uses serrated flange bolts, toothed nuts, and self-locking safety bolts to prevent loosening, ensuring the steering remains precise and responsive.
Every pipe and bracket in this Power steering device is pre-formed to the exact dimensions of the HOWO MAX 4X2, guaranteeing that installation is straightforward and alignment is perfect.
The part uses a hydraulic vane pump driven by the engine to generate pressurised fluid. This fluid is routed through steel pipes and hoses to the steering gear, where it assists the driver’s input by applying force to the steering linkage. The gear’s internal rotary valve directs fluid to either side of the piston, providing boost proportional to steering effort. The oil reservoir and return hose complete the circuit. Regular maintenance of The part fluid level and belt tension ensures consistent assist and reduces steering effort.
Before installation, ensure the engine is cool and the vehicle is raised securely. Remove the old steering components and clean the mounting areas. Install the steering gear bracket, then mount the power steering gear using the M16 and M12 bolts. Attach the vane pump to its bracket with the M10 and M8 fasteners. Route the steel pipes and hoses according to the chassis routing, securing them with the single and dual clamps. Connect the high-pressure hose to the pump and gear. Install the reservoir clamp and connect the return hose. Bleed The part by turning the wheel lock-to-lock with the engine running, topping up fluid as needed. Check all connections for leaks. The part is now ready for use.
If steering becomes heavy, check the pump belt tension and fluid level. A whining noise from The part often indicates low fluid or air in the system; bleed the system and top up. Fluid leaks from hoses or joints require replacement of the damaged component. A loose steering feel may be due to worn gear mounting bolts; retorque to specification. If the pump fails, replace the steering vane pump with a genuine unit. Always use the correct fluid type (Dexron III or equivalent) for The part.
Inspect The part fluid level every 20,000 km and top up if needed. Replace the fluid and filter every 100,000 km or sooner if contaminated. Check all hoses and pipes for cracks, chafing, or corrosion. Ensure all clamps and brackets are secure. Lubricate the steering linkage joints. A well-maintained Power steering device ensures effortless steering and extends the life of the pump and gear.
This Power steering device kit is designed for the HOWO MAX 4X2 tractor, compatible with MC11 and MC13 engines and all production years from 2018 onward. It also fits SITRAK C7H and HOWO T7H models with identical steering architecture. The left-handed pump is specific to these configurations. It is not compatible with older WD615 models. Always verify your chassis number before ordering The part kit.
Aftermarket Power steering device components often use inferior seals and hoses that burst under pressure, leading to sudden loss of assist. Generic fasteners may not hold torque, causing misalignment. Genuine HOWO Power steering device components are manufactured to SINOTRUK’s exacting standards, with certified materials and rigorous testing. The small additional cost of a genuine kit is far outweighed by the safety and reliability of a properly functioning Power steering device.
