This complete assembly integrates the primary door part mechanism, the fuel tank cover The part, and the ignition The part core into a single keyed set. It ensures that one key operates all three parting points, simplifying vehicle access and security. The part assembly is precision‑engineered with hardened steel tumblers and a durable chrome‑plated housing to resist wear and environmental corrosion.
The Limit drawstring fixing plate is a sturdy steel bracket that anchors the door limit drawstring to the door frame. It is designed to withstand repeated tension and ensures that the drawstring remains securely attached, preventing the door from swinging too far open.
The Limit drawstring assembly consists of a durable woven strap with a metal stop and loop. It limits the door’s opening angle, protecting the hinges and bodywork from over‑extension. This assembly is a vital safety component of The part system, preventing damage during high‑wind or sloped parking.
This combined fastener includes a cross‑recessed pan head tapping screw with a pre‑assembled flat washer. It is used to secure the limit drawstring plates and other trim components. The washer distributes load and prevents damage to the panel surface.
A standard cross‑recessed pan head screw is used for general fastening of interior trims, part housings, and electrical components. Its zinc‑plated finish offers good corrosion resistance, and the cross recess allows for quick installation with a standard screwdriver.
These high‑strength screws feature a hexalobular (Torx) socket countersunk head, providing superior torque transfer and reduced cam‑out. They are used for critical security fastenings, such as the door part mechanism, where tamper resistance is required.
The Plastic fastening belt is a reusable cable tie with a length of 280mm and a width of 5mm. It is used to bundle and secure wiring harnesses and tubes within the door cavity, preventing rattles and chafing.
This medium‑strength anaerobic adhesive is applied to threads before assembly to prevent loosening from vibration. It is essential for securing critical fasteners in The part system, ensuring they remain tight throughout the vehicle’s service life.
The Axis pin is a precision‑ground steel pin used as a pivot for the door part linkage or other moving mechanisms. Its hardened surface reduces wear and ensures smooth operation of The part components.
The Cotter pin is a split pin used to secure the axis pin or other removable fasteners, preventing them from working loose. It is made from spring steel and can be easily bent and removed for maintenance.
This self‑tapping screw has a half‑round head with a cross recess, ideal for attaching plastic or thin metal components. Its thread cuts into the mating material, providing a secure hold without the need for a pre‑tapped hole.
The Tapered teeth locking washer is a spring‑like washer with angled serrations that bite into the bolt head and mating surface. It provides a positive locking action that prevents fasteners from loosening due to vibration, a critical feature in the heavy‑duty environment of a dump truck.
Our LOCK kit is manufactured to Sinotruk’s original specifications, ensuring a perfect key match and seamless operation. The integrated The part cores are coded to the same key, providing convenience and enhanced vehicle security.
All fasteners and locking components are designed to withstand the high vibration environment of a dump truck. The thread adhesive and tapered locking washers ensure that every screw and bolt remains tight, reducing the risk of loose parts and rattles.
We supply every screw, pin, washer, and adhesive needed for a full installation of The part system. No additional parts are required, saving you time and ensuring a professional, thorough repair.
With pre‑matched lock cores and clearly labelled fasteners, The part kit is designed for straightforward replacement. The high‑quality materials and corrosion‑resistant coatings ensure that your door locks and hardware remain reliable for years.
The part kit is a comprehensive solution for rebuilding the door locking and security hardware on the HOWO 7 6×4 dump truck. It addresses all aspects of door closure, from the main part to the limit drawstring, and includes every fastener needed to secure these components properly.
The integrated door lock, fuel tank cover, and ignition lock core assembly is a major time‑saver, as it eliminates the need to re‑key or carry multiple keys. The part core is manufactured with high‑precision wafers and springs, providing smooth rotation and positive engagement. This part set is a direct replacement for the original factory unit.
The limit drawstring assembly and its fixing plate work together to protect the door hinges and bodywork. Without a functioning limiter, the door can swing too far, damaging the hinges or the cab structure. Our LOCK kit includes two complete sets, one for each door, ensuring balanced protection.
All fasteners are selected for their corrosion resistance and clamping ability. The cross‑recessed pan head screws are suitable for general applications, while the hexalobular socket countersunk screws offer higher strength and tamper resistance for security‑critical areas. The thread‑locking adhesive provides an extra level of safety, ensuring that screws do not back out due to road vibration.
The axis pin and cotter pin are used in the door hinge or lock linkage mechanism. The axis pin provides a smooth pivot, while the cotter pin secures it in place, preventing accidental disassembly. These small but crucial parts are often overlooked during repairs, but our LOCK kit includes them as standard.
The plastic fastening belt is a handy cable management solution that keeps wiring and tubes neatly bundled, preventing them from interfering with The part mechanism or window operation. It is reusable and easy to install.
Replacing the entire LOCK kit is a proactive maintenance step that can prevent door‑related issues such as sticking locks, broken drawstrings, or rattling panels. Rather than replacing individual components piecemeal, this kit provides a complete, matched set that ensures all parts work together harmoniously.
Installation of The part system is straightforward with basic hand tools. The part assembly is a direct bolt‑on replacement, and the drawstring brackets attach using the supplied screws. The adhesive should be applied to the threads of critical fasteners as per the instructions.
For fleet operators, standardising on this genuine LOCK kit ensures consistent quality and security across all vehicles. The matched lock cores simplify key management, as one key can be used for multiple locks, reducing the number of keys that need to be carried.
The tapered teeth locking washer is a simple but effective anti‑loosening device that digs into the bolt head and the surface beneath, providing a mechanical lock that resists vibration. It is used on high‑stress fasteners within The part system.
The cross‑recessed half‑round head tapping screw is specifically designed for attaching plastic covers and liners, providing a secure hold without damaging the material. Its rounded head reduces the risk of snagging on clothing or other objects.
All components are packaged in a durable box with clear labelling, making it easy to identify each part during installation. We also provide a detailed torque specification sheet for critical fasteners.
We back our LOCK kit with a 12‑month warranty against manufacturing defects. Our technical support team is available to assist with any installation or compatibility questions.
We ship worldwide with tracking. Expedited shipping is available for urgent orders. Use the Send Email or Get Quotation buttons to request a customised quote for your fleet.
Choosing a genuine LOCK kit ensures that your HOWO 7 maintains its original security and durability. Aftermarket parts may not have the same key coding or material quality, leading to mismatched keys or premature wear.
The thread anti‑loosening adhesive is a medium‑strength compound that allows for future disassembly with hand tools, unlike high‑strength adhesives that require heat. This balance makes it ideal for maintenance‑friendly installations.
The plastic fastening belt is made from UV‑stabilised nylon, ensuring it does not become brittle over time, even in direct sunlight.
