This Side guard mounting device includes every bracket, plate, bolt, nut, and washer needed for a full side guard installation. No additional hardware is required, making this Side guard mounting device a complete, ready-to-install solution.
All steel components in this Side guard mounting device are made from high-strength materials with zinc-nickel or galvanised coatings, providing excellent corrosion resistance and long service life in harsh road conditions.
The part uses serrated flange bolts, toothed nuts, and embedded locking washers to provide a positive, vibration-proof fastening system that maintains structural integrity over the life of the vehicle.
Every component of this Side guard mounting device is manufactured to SINOTRUK’s exact specifications, guaranteeing that all brackets and plates align perfectly with the chassis mounting points of the HOWO MAX 4X2.
The part system is designed to securely attach the side underride protection guards to the chassis frame. The side protection mounting brackets are bolted directly to the chassis rails using the M16 serrated bolts and toothed nuts, providing the primary structural connection.
The tank-side brackets attach to the fuel tank side of the chassis, accommodating the tank’s position. The connecting plates bridge between the brackets and the side guard rails, allowing for adjustment and alignment during installation. The M8 and M10 flange bolts and nuts secure the connecting plates and brackets together, while the embedded locking washers prevent loosening under vibration. The blanking caps cover unused mounting holes,
protecting them from corrosion. The entire Side guard mounting device is engineered to withstand the forces encountered during normal driving, including impact from road debris and side-impact forces. A properly installed Side guard mounting device ensures that the side guards remain firmly attached, providing protection for the vehicle and other road users.
Before installing The part, ensure the vehicle is on level ground and the chassis mounting points are clean and free from debris. Position the side protection mounting brackets on the chassis rails and secure them using the M16 serrated flange bolts and toothed nuts (torque to 180 Nm). Attach the tank-side brackets to the chassis using the M8 flange bolts (torque to 25 Nm). Connect the connecting plates to the brackets using the M10 flange bolts and nuts (torque to 40 Nm),
and secure them with the embedded locking washers. Install the side guard rails onto the connecting plates and adjust their position for correct alignment.
Torque all fasteners to the specified values in a crossing pattern. Install the blanking caps into any unused holes. After installation, check that all fasteners are secure and that The part is rigid and does not move under hand pressure. The part is now ready for service.
If The part is loose or rattles, check that all bolts and nuts are torqued to the correct specification. Loose fasteners can allow the brackets to move, causing noise and potential damage.
If a bracket is bent or damaged, it must be replaced to maintain the structural integrity of The part. Missing blanking caps can allow moisture into unused holes, leading to corrosion; replace them promptly.
If the embedded locking washers have lost their spring tension, replace them with new ones. Corrosion on the bolts can make removal difficult; use penetrating oil and replace the fasteners if they are seized. Always use genuine Side guard mounting device components for repairs to ensure correct fit and safety.
Inspect The part at every scheduled service (every 50,000 km). Check that all bolts and nuts are tight and that there is no visible corrosion or damage to the brackets and plates. Retorque the M16 bolts to 180 Nm and the M10 and M8 fasteners to their specified torques. Inspect the blanking caps for damage and replace any missing ones.
If the vehicle operates in corrosive environments, consider applying an additional rust-proofing coating to The part components. A well-maintained Side guard mounting device ensures the side guards remain securely attached, providing protection and complying with safety regulations.
This Side guard mounting device kit is specifically designed for the HOWO MAX 4X2 tractor and is compatible with all production years from 2018 onward. It fits both MC11 and MC13 engine variants and is designed to accommodate the standard fuel tank and chassis configuration.
