Dongfeng KL Manual oil pump assembly 5005010-C3105

As a critical emergency and maintenance component, this manual oil pump delivers exceptional suction efficiency to meet Dongfeng KL’s oil transfer needs. It features a dual-stage piston structure with a maximum suction lift of 3 meters and a flow rate of 1.2L/min—capable of transferring 4L of engine oil (the standard oil capacity for Dongfeng KL’s Yuchai 6K engine) in just 3.5 minutes. The pump’s internal check valve (made of nitrile rubber) ensures one-way oil flow, preventing backflow during pumping and maintaining oil pressure in the pipeline. Additionally, the pump’s handle is designed with a 150mm lever length and ergonomic non-slip grip, reducing the force required for each stroke (operating force ≤ 25N) and minimizing operator fatigue during prolonged use (e.g., refueling multiple trucks in a fleet)

Constructed to withstand long-term contact with various oils (engine oil, gear oil, diesel), the pump’s main body is crafted from glass-fiber reinforced polypropylene (PP+30% GF)—a material with excellent chemical resistance that does not degrade or swell when exposed to mineral oils, synthetic oils, or diesel fuel (tested to resist oil immersion for 1000 hours without dimensional changes). The internal piston and seals use fluororubber (FKM)—resistant to high temperatures (up to 200℃) and oil aging, ensuring a tight seal (oil leakage rate ≤ 0.05mL/min at maximum suction pressure) and extending the pump’s service life. The pump’s metal components (e.g., connecting rods, fasteners) are made of stainless steel (304 grade), providing rust resistance even in humid or oily working environments (passing 500-hour salt spray testing per ASTM B117 standards)

Optimized for on-board storage and emergency scenarios, this manual oil pump features a compact structure with overall dimensions of 220mm × 80mm × 65mm and a weight of only 0.8kg—easily fitting into the Dongfeng KL’s cab toolbox or under-seat storage compartment. The pump’s handle is foldable, reducing its storage length by 40% (from 220mm to 132mm) when not in use, and it locks securely in the folded position to prevent accidental damage during transportation. The pump’s body also has a reinforced impact-resistant design—able to withstand a 1-meter drop onto concrete without cracking (tested per IEC 60068-2-32 standards)—ensuring durability in rough handling conditions (e.g., construction site maintenance or roadside emergencies)

This manual oil pump assembly is versatile enough to support multiple maintenance scenarios for Dongfeng KL trucks, including: ① emergency engine oil supplementation (adding oil when the engine oil level is too low to start); ② oil change for small components (draining or refueling the gearbox, differential, or power steering system); ③ fuel transfer (topping up diesel fuel from a reserve tank to the main tank). Maintenance is simple: the pump’s detachable design allows easy disassembly of the piston and seals for cleaning or replacement (no special tools required), and all replacement parts (e.g., FKM seals, check valves) are standardized to OEM specifications, ensuring easy sourcing. The assembly also comes with a 1.5-meter oil-resistant hose (compatible with the inlet port) and a user manual with step-by-step operation guides, making it accessible even for non-professional technicians. It complies with China’s GB/T 18831-2019 “Automotive Maintenance Tools Safety Requirements” and is backed by a 12-month warranty
