making This part ideal for custom installations. The hole pattern is aligned to match standard fastener sizes (M8, M10, and M12), ensuring compatibility with common hardware. The part is laser‑cut to exact dimensions and deburred for safe handling. In the HOWO MAX 4X2, the perforated plate is often used to reinforce the chassis side rails or as a mounting base for auxiliary fuel tanks and toolboxes.
Its open design reduces weight while maintaining structural integrity, contributing to overall vehicle efficiency. The part’s surface is coated with a protective e‑coat primer that resists chipping and scratching, ensuring a long service life even in harsh environments.
Regular inspection of This part is recommended to ensure that no cracks develop around the perforations, especially in high‑vibration areas. If The part becomes damaged, it should be replaced with a genuine HOWO unit to maintain the original strength and fitment.
The backing plate is a solid steel reinforcement that provides a robust, flat mounting surface behind the perforated plate or in other load‑bearing areas. This part component is made from the same high‑strength steel as the perforated plate,
with a thickness of 8mm for added rigidity. The backing plate is designed to distribute concentrated loads over a wider area, preventing stress fractures in the chassis or mounting brackets. It features precision‑drilled holes that align with the perforated plate, allowing for bolted connections that spread the clamping force evenly.
The part’s surface is also e‑coat primed for corrosion protection. In the HOWO MAX 4X2, the backing The part is often used in conjunction with the perforated The part to create a strong, vibration‑resistant sandwich structure for mounting heavy components such as winches, tow hooks, or suspension brackets.
The part’s solid design also serves as a spacer or shim where additional clearance is required. When installing This part, it is essential to use the correct torque values for the fasteners to prevent distortion. The backing The part is a critical safety component; any signs of deformation or cracking require immediate replacement with a genuine HOWO Plate.
The part is also used in cab mounting and engine support brackets, where its rigidity ensures stable alignment of drivetrain components. Properly installed, This part provides decades of reliable service.
Plate – genuine HOWO perforated and backing plate kit for MAX 4X2
The perforated plate offers unlimited mounting possibilities with its pre‑drilled hole pattern, while the backing plate adds strength and load distribution. Together, This part set provides a versatile solution for attaching accessories and reinforcing chassis structures.
Both plates are fabricated from 600 MPa HSLA steel, providing exceptional strength and fatigue resistance. The part set is built to withstand the heavy loads and vibration encountered in demanding truck applications.
Each Plate is coated with a durable e‑coat primer that protects against rust and chemical attack. This part treatment ensures long‑term durability, even when exposed to road salts and moisture.
This part kit is manufactured to SINOTRUK’s original specifications, guaranteeing that the perforated and backing The parts align perfectly with the chassis mounting points. Installation is simple and requires no modifications.
The perforated The part in this kit has overall dimensions of 300mm x 200mm x 6mm, with a hole pattern of 16 rows of 10mm diameter holes at 25mm centres. The part is designed to accept M8, M10, and M12 fasteners, providing flexibility for various attachments. The backing The part measures 280mm x 180mm x 8mm and is pre‑drilled with matching bolt holes. Both The parts are manufactured using a CNC laser‑cutting process that ensures burr‑free edges and precise hole placement.
The e‑coat primer is applied through an electro‑deposition process, achieving a uniform coating thickness of 25 microns. This part finish meets the ISO 12944‑2 C5 corrosion protection standard, suitable for high‑humidity and salt‑laden environments. The weight of the perforated The part is 2.8 kg,
while the backing The part weighs 3.2 kg, contributing minimally to overall vehicle weight while providing substantial structural benefit. The part components are supplied with a protective oil coating that should be wiped off before installation.
Before installing The part, clean the chassis area thoroughly to remove dirt and rust. Position the perforated The part against the mounting surface and mark the locations of the required holes. If additional holes are needed, The part can be drilled using a standard drill bit (note: drilling will remove the e‑coat at that point;
touch up with primer afterwards). Place the backing The part behind the chassis frame, aligning its holes with those of the perforated The part. Insert the appropriate grade 8.8 bolts through the perforated The part, the chassis,
and the backing The part. Secure with flange nuts and torque to the recommended values (M8: 25 Nm, M10: 40 Nm, M12: 60 Nm). Ensure that The part is flat and that there is no distortion. Check that all bolts are tight and that The part does not interfere with any moving parts. The installation is now complete.
If The part develops a rattle or seems loose, check the bolt torque and retighten as necessary. Loose bolts can allow The part to move, causing wear on the mounting holes and potential stress fractures. If the perforated The part bends under load, it may indicate that the backing The part is not correctly positioned or that the bolts are not properly torqued.
In high‑corrosion environments, inspect The part for rust; if the e‑coat is damaged, touch up with a suitable primer to prevent further corrosion. If a crack appears in either The part, it must be replaced immediately, as The part is a structural component. Always use genuine HOWO The part replacements to maintain the original strength and fit.
Inspect The part system every 50,000 km or during annual chassis maintenance. Check for signs of corrosion, cracking, or deformation. Retorque all mounting bolts to ensure they have not loosened. Clean The part surfaces with a degreaser and apply a rust‑proofing spray if the vehicle operates in coastal or winter‑salt areas.
The part is designed for a long service life, but regular inspection will identify any issues early and prevent failure. If The part is used for mounting heavy equipment, inspect it more frequently, especially after off‑road use.
This part kit is designed for the HOWO MAX 4X2 tractor and is compatible with all production years from 2018 onward. The perforated and backing The parts are sized to fit the standard chassis rail width and bolt patterns.
The part kit is also suitable for SITRAK C7H and HOWO T7H models that share the same chassis dimensions. It is not compatible with older A7 or WD615 models, which use different bolt spacings and rail profiles. Always verify the chassis hole pattern before ordering The part kit. The part components are ideal for mounting auxiliary fuel tanks, toolboxes, air tanks, and other aftermarket accessories.
Aftermarket Plate components are often made from lower‑grade steel that lacks the required tensile strength, leading to deformation under load. Generic plates may have inconsistent hole patterns, requiring drilling that can weaken the material.
Non‑genuine The parts lack the proper corrosion protection, leading to rapid rusting and premature failure. A failed The part can cause mounted equipment to detach, posing a serious safety hazard.
Genuine HOWO Plate components are manufactured to SINOTRUK’s exacting standards, using certified HSLA steel, precision‑cut patterns, and robust e‑coat protection. The small additional cost of a genuine Plate kit is insignificant compared to the safety and reliability it provides. For fleet operators, using genuine Plate kits ensures consistent strength and fit across all vehicles, reducing the risk of equipment loss and downtime.
