KANGDA 2QT29 / BH2QT95R9 – Inline Fuel Pump For 2110(2113) Diesel Blocks

This KANGDA fuel pump assembly, listed under order code 2QT29 and model BH2QT95R9, delivers a direct-fit solution for mechanical diesel systems found in 2110 and 2113 engine platforms. Designed around the Bosch-style inline pumping principle, this unit translates camshaft rotation into precisely pressurized fuel pulses, feeding individual injectors in firing order. For workshops handling agricultural tractors, stationary gen-sets, or compact loaders, this replacement part restores factory-fresh fuel delivery without modifying existing fuel lines or mounting brackets.

Engine speed is capped at 1500 RPM, with power band spanning 22.5 kW to 24 kW depending on governor settings and nozzle break pressure. The pump housing carries a hardened camshaft supported by tapered roller bearings, minimizing radial play even after thousands of operating hours. Plunger barrels are manufactured from nitrided steel and lapped to micron-level clearances, reducing internal leakage and maintaining injection consistency across all cylinders. A mechanical flyweight governor adjusts fuel rack position based on load fluctuation, preventing overspeed conditions when implements engage or disengage suddenly. This particular BH2QT95R9 calibration incorporates specific delivery valve pre-lift characteristics tuned to the combustion chamber design of Yongkang's 2110 family, ensuring ignition delay stays within acceptable limits across ambient temperature variations.

Primary fitment covers 2110 and 2113 series engines, widely deployed in compact utility tractors, small wheel loaders, and auxiliary power units manufactured by OEM Yongkang. These engines appear throughout European farmland, greenhouse operations, and municipal maintenance fleets where space constraints and part commonality drive purchasing decisions. The KANGDA 2QT29 also cross-references against equipment carrying similar displacement and firing order, though technicians must always verify the drive gear orientation before bolting the new pump onto the timing gear case. Unlike electronically managed units, this mechanical pump operates independently of ECU inputs, making field repairs straightforward when diagnostic tools are unavailable.

Before installation, clean the mounting flange thoroughly and confirm the O-ring groove contains no debris from the previous seal. The pump shaft features a Woodruff key slot that must align with the drive gear hub; forcing misaligned components risks shearing the key and damaging internal cam followers. Rotate the crankshaft to bring the engine to top dead center on the compression stroke for cylinder one, then check that the scribe line on the pump's timing window corresponds to the delivery start mark indicated in the service manual. Tighten the retaining nuts progressively, alternating sides to create even clamping pressure across the aluminum housing. After securing the pump, bleed the low-pressure circuit using the hand primer before cracking each injector line to evacuate entrapped air – a step often overlooked but critical for avoiding hydraulic lock and delayed pressure buildup.

Q1: Does this pump include the delivery valve holders and springs, or must I transfer from my old assembly?
A: The BH2QT95R9 is supplied with delivery valve assemblies already installed and calibrated. You simply transfer the high-pressure lines and injector nuts from your previous unit.

Q2: What fuel specification does KANGDA recommend for achieving maximum plunger life?
A: Use diesel meeting EN 590 or ASTM D975 with minimum 2% biodiesel content. Water separators must be drained weekly to prevent micro-cavitation damage on plunger faces.

Q3: How do I distinguish genuine KANGDA parts from grey-market copies that fail prematurely?
A: Authentic units display laser-etched 2QT29 batch codes on the governor cover and feature a red paint dot on the delivery valve holder – counterfeits often omit these markings.

Q4: Can this pump run on hydrotreated vegetable oil (HVO) or synthetic diesel blends?
A: Yes, the nitrile seals and steel components withstand HVO's lower lubricity, but we recommend adding a lubricity additive if operating continuously on paraffinic fuels.

Q5: What is the warranty coverage for commercial workshop purchases exceeding five units?
A: Standard 12-month manufacturer warranty against material defects, extendable to 18 months for registered trade accounts submitting quarterly service records.

Q6: Does this part supersede earlier pump models that used different mounting stud patterns?
A: No – this KANGDA 2QT29 matches the three-stud triangular flange pattern of late-production 2110 engines. Earlier stud arrangements require an adapter plate not sold separately.
