KANGDA 3QF95/3QF95LD-1 | BH3Q60R8 Diesel Injection Pump For LL380Q

The KANGDA 3QF95 and 3QF95LD-1 fuel injection pumps, identified by order number BH3Q60R8, represent a dedicated high-pressure fuel delivery solution engineered specifically for the Laidong LL380Q three-cylinder diesel engine. Operating at a rated speed of 3200 RPM and delivering 22 kW of mechanical output, this pump is a critical component within the common rail system or mechanical distributor-type injection setup, ensuring precise fuel metering and atomization for agricultural vehicles, low-speed trucks, and industrial equipment. Designed to meet stringent OEM specifications from the host manufacturer, Laidong, this unit provides the hydraulic pressure necessary to overcome compression ratios and maintain efficient combustion under sustained load conditions.

The KANGDA BH3Q60R8 pump is precisely calibrated to match the thermodynamic characteristics of the LL380Q engine-a 1.357L, water-cooled, three-cylinder powerplant with a bore and stroke of 80×90 mm . The pump's delivery characteristics are synchronized with the engine's 3200 RPM rated power band, ensuring that fuel injection timing and quantity align with the compression ratio for optimal thermal efficiency. With a power rating of 22 kW, this pump supports applications ranging from agricultural tricycles to stationary power units, maintaining stable rail pressure across varying load demands. Its robust internal cam mechanism and precision-ground plungers are engineered to withstand the torsional vibrations inherent in three-cylinder configurations, delivering consistent flow rates that maximize the engine's low-end torque output.

This injection pump is primarily utilized in vehicles manufactured for utility and cargo transport, including the Chuanjiang CJ1610 series and Foton Lovol Wuxing 7YPJZ tricycles . The BH3Q60R8 serves as a direct replacement or service part for diesel repair shops handling light-duty commercial fleets and agricultural machinery. Designed to interface seamlessly with the Laidong power unit, the KANGDA pump supports the shaft-driven drivetrains common in low-speed vehicles, providing reliable fuel delivery under the dusty, high-vibration conditions typical of rural and construction environments. For distributors and workshops, stocking this variant ensures coverage for a significant number of LL380Q-equipped vehicles circulating in both domestic and export markets.

In the context of common rail and high-pressure mechanical systems, the KANGDA BH3Q60R8 is often chosen for exchange programs or as a remanufactured core, offering shops a balance between cost and reliability . Rebuilding this unit requires specialized pump test equipment to calibrate the delivery valves and governor settings specific to the LL380Q's 3200 RPM power curve . The service value lies in restoring the system to OEM pressure tolerances, thereby eliminating issues like surging, loss of power under load, and excessive vibrations that typically indicate internal pressure inconsistencies . For repair shops, sourcing genuine KANGDA units ensures warranty protection and minimizes the risk of core rejection due to cracked housings or missing components, ultimately providing customers with a durable, performance-verified solution for their agricultural diesel applications.

Q1: How do I verify that the BH3Q60R8 pump is compatible with a specific LL380Q engine variant?
A: Confirm the engine serial number and ensure the vehicle's RPM range matches the 3200 RPM specification. All Laidong LL380Q models with a 22 kW power rating share the same pump mounting flange, but verify the injector line connections match your specific chassis configuration.

Q2: What is the typical core charge policy for returning failed KANGDA 3QF95 units?
A: Most exchange providers require the core to have an intact housing and undamaged mounting ears. Units with severe internal seizure or missing delivery valves usually incur a higher core charge or rejection.

Q3: Does this pump require specific lubrication for the ULSD (Ultra-Low Sulfur Diesel) fuel?
A: Yes. To mitigate wear from reduced sulfur lubricity, we recommend using a fuel additive or ensuring the LL380Q engine is running fuel that meets ASTM D975 standards, alongside regular filter changes.

Q4: Why do we need to flush the fuel rail when installing this pump?
A: Metal particles from a previous pump failure can contaminate the new 3QF95LD-1, leading to immediate plunger scoring. Flushing prevents this and ensures warranty validity.

Q5: What is the estimated lifespan for this KANGDA pump in agricultural applications?
A: Under regular maintenance, these units often exceed 8,000 hours of operation. However, high ambient dust and fuel quality are the primary factors determining the lifespan of the internal pumping elements.
