Dongfeng KInland truck parts Quick connector wrench assembly 3901080-T38A0

A core advantage of the 3901080-T38A0 assembly is its ergonomic design, optimized for long-term use in tight truck engine compartments. The wrench features a rubberized, non-slip handle that reduces hand fatigue during repeated connector installations or removals—critical for technicians working on multiple Kinland trucks daily. Its angled jaw (15° offset) allows access to hard-to-reach connectors near the engine block or chassis, eliminating the need to disassemble adjacent components. The handle’s balanced weight distribution (350g total) ensures precise control, while the smooth jaw action prevents “sticking” when turning connectors. For technicians, this design cuts down connector service time by 30% compared to standard wrenches, improving overall maintenance efficiency

Built to withstand the rigors of Kinland truck maintenance, the 3901080-T38A0 wrench uses high-strength materials. The jaw is made of chrome-vanadium steel (Cr-V 50BV30), heat-treated to 50-55 HRC hardness—resisting wear and deformation even after 1,000+ uses on metal connectors. The handle is crafted from impact-resistant ABS plastic, capable of withstanding accidental drops (up to 1.5m) without cracking. The wrench’s moving parts are lubricated with anti-rust grease, ensuring smooth operation in dusty or humid workshop environments. Rigorous durability tests (500+ torque cycles, 200-hour salt spray exposure) confirm it maintains functionality for 5+ years, outlasting generic wrenches that often break or lose grip over time

The 3901080-T38A0 assembly is a versatile tool that works across multiple Dongfeng Kinland systems, eliminating the need for separate wrenches. It efficiently services quick connectors in the truck’s fuel system (e.g., fuel filter connectors), air brake system (e.g., brake chamber hoses), and cooling system (e.g., radiator hoses)—covering 90% of Kinland’s common quick connector applications. The wrench’s adjustable jaw allows it to adapt to both metric and imperial connector sizes (a common need for mixed-fleet workshops), while its non-marring jaw surface protects plastic connectors from scratches that could lead to leaks. For fleet managers, this multi-functionality reduces tool inventory costs and simplifies tool storage in service vehicles

The 3901080-T38A0 wrench integrates safety features to protect Kinland’s critical connectors. Its jaw is lined with a soft, non-metallic insert that prevents metal-on-metal contact—avoiding scratches on plastic quick connectors that can compromise their sealing ability. The wrench’s torque-limiting design (built-in at 50 N·m) stops turning once the optimal torque is reached, preventing over-tightening that could crack connector housings or strip threads. Additionally, the handle’s bright orange color makes it easy to locate in cluttered toolboxes, reducing the risk of leaving the wrench in the truck after maintenance (a common safety hazard). For Kinland operators, these features minimize the risk of post-maintenance leaks or connector failures, ensuring truck systems operate safely
