The WG1642341011 assembly integrates the door latch mechanism and fuel filler lock into a single, robust unit. The door latch is constructed from zinc alloy die‑castings with hardened steel pawls and striker engagement surfaces, ensuring secure closure and resistance to forced entry. The fuel tank cover is equipped with a cam lock that uses a unique key profile, preventing unauthorized fuel siphoning and tampering. All moving parts are coated with a corrosion‑resistant finish, making the assembly suitable for harsh environments.
Each WG1642341011 assembly is precision‑assembled and tested for smooth operation. The latch mechanism undergoes 50,000 cycle tests to ensure durability, while the lock cylinder is tested with over 10,000 key insertions. The fuel tank cover seal is made from UV‑stabilized EPDM rubber, providing a water‑tight closure that prevents dust and moisture ingress. This comprehensive design ensures long‑term reliability and security for your Howo truck.

The WG1642341011 assembly is designed for the cab door and fuel tank of Howo heavy‑duty trucks. It mounts on the door panel (latch mechanism) and on the fuel filler neck (lock cover). The door latch ensures the door remains securely closed during travel, while the fuel tank cover lock prevents fuel theft and contamination. This combination is especially critical in remote mining and construction sites where fuel security is a concern.
In the chassis context, the assembly must withstand constant vibration, temperature extremes, and exposure to road grime. The genuine WG1642341011 unit is engineered to maintain smooth operation under these conditions. It is used on both driver and passenger side doors (handed versions may differ, verify orientation). It is also compatible with various cab styles, including day cabs and sleeper cabs, ensuring consistent security across your fleet.
When replacing the assembly, check the door striker plate and fuel neck condition. Use the supplied gasket for the fuel cover to ensure a proper seal. Test the lock function before final assembly.
Correct installation of the WG1642341011 assembly ensures reliable security and smooth operation. Follow these steps:
Remove the door panel to access the old latch. For the fuel cover, open the fuel door and remove the retaining screws. Clean the mounting surfaces thoroughly.
Install the new latch and secure with bolts (torque 10‑12 Nm). Attach the fuel cover with the new gasket. Ensure the lock cylinder rotates freely. Connect any linkage rods.
Test the door operation: it should close securely and open smoothly. Verify the fuel cover locks and unlocks with the key. Lubricate the latch mechanism with white lithium grease if needed.
A failing latch or lock compromises security and convenience. Common signs that replacement is needed include:
If any of these symptoms are observed, immediate replacement with a genuine WG1642341011 assembly is recommended. A failed latch can lead to door opening unexpectedly, posing a safety risk. A compromised fuel lock can result in fuel theft or contamination.
The integrated lock with unique key code prevents unauthorized access to the cab and fuel tank, protecting your assets and cargo.
Corrosion‑resistant materials and rigorous testing ensure reliable operation in harsh environments, reducing replacement frequency.
OEM design guarantees direct bolt‑on replacement, saving installation time and ensuring proper alignment with door and fuel filler.
To maximize the service life of your WG1642341011 assembly, follow these best practices:
By adhering to these guidelines, you ensure that the WG1642341011 assembly performs optimally throughout its intended service interval.
Aftermarket latch and lock assemblies often use inferior die‑cast alloys that corrode quickly, and their lock cylinders have poor key code variation, making them easier to pick. The genuine WG1642341011 is manufactured to the exact specifications of the original equipment, using high‑strength zinc alloy and hardened steel components. Each lock cylinder is uniquely keyed, and the assembly is tested for cycle life and environmental resistance. It guarantees reliable security and smooth operation for the life of your truck.
By choosing authentic SINOTRUK HOWO parts, you protect your investment and ensure your truck maintains its security and resale value. The Sinotruk howo parts catalog includes a full range of cab and chassis components engineered for maximum durability. For fleet managers and owner‑operators who demand the best, the genuine WG1642341011 is the only responsible choice.
The WG1642341011 assembly is used across a wide range of Howo models: T7H, A7, and classic Howo‑7 series. It fits both left and right doors, but the orientation of the latch mechanism may vary; always verify the door side when ordering. The fuel cover fits standard Howo filler necks (85 mm opening).
Each WG1642341011 is individually packaged in a protective box with foam inserts. The package includes the latch assembly, lock with two keys, fuel cover with gasket, and mounting hardware. A key code tag is attached for reordering duplicate keys.
Production of the WG1642341011 takes place in ISO/TS 16949 certified facilities, using precision die‑casting and automated assembly. Statistical process control ensures that dimensional variations are kept to a minimum. Every batch is accompanied by a material certificate and functional test report, guaranteeing that the assemblies delivered are identical to those fitted on new Howo trucks at the factory.
