2QT55 | BH2QT95R9 KANGDA Fuel Injection Pump For Liuchai 2115

For a service bay dealing with Liuchai 2115-powered machines, every hour the bay is empty translates to lost revenue and delayed customer commitments. This KANGDA 2QT55 (ordering code) / BH2QT95R9 (pump model) is the direct-fit solution to get that 37 kW engine back on the job-whether it's powering a generator set or a piece of construction equipment-without the guesswork that inflates labor costs. Rated for 2400 RPM, this unit eliminates the variables that often turn a simple pump swap into a week-long diagnostic headache.

The BH2QT95R9 carries a 9 mm plunger diameter and mounts directly to the Liuchai 2115 timing gear housing with clockwise rotation (viewed from the drive end). Static timing is set at 22° ± 1° BTDC; delivery valve holders need 50-60 Nm, mounting nuts 25-30 Nm. These are not approximate figures-they are the numbers that prevent a rushed install from turning into a callback next Tuesday. The pump is built around a distributor-type pumping element, which means fewer moving parts compared to inline designs, directly cutting down the internal wear points that send shops searching for elusive intermittent faults.

Stocking one pump that covers the Liuchai 2115 and cross-fits select YuChai and ChangChai variants with matching bore spacing means less capital tied up on the shelf. Instead of juggling multiple SKUs for different chassis, this 2QT55 unit streamlines your parts cabinet. For workshops that service agricultural tractors, skid-steer loaders, and stationary power units, this cross-coverage reduces the risk of carrying dead stock-money that could otherwise be spent on fast-moving consumables. The 37 kW power rating aligns with the most common industrial derating curves, so you are not forced to recalibrate the governor spring tension for every job; it comes ready to run within the original equipment parameters.

In a working shop, the cost of a failed pump is not just the part price-it is the crane time, the fluid top-up, the two hours of troubleshooting, and the customer who is now staring at a penalty clause for late delivery. This KANGDA unit addresses the most common failure mechanism in distributor pumps: bore wear from abrasive contaminants that slip past marginal filtration. Rather than selling a "long-life" promise, we offer a pump with hardened plunger barrel metallurgy that reduces the progressive clearance growth which causes internal leakage and timing drift. When a unit wanders off timing, the injector nozzles coke unevenly, leading to a cascade of second-order repairs-nozzle swaps, line flushing, and governor adjustments-that eat up bay productivity. Fitting a fresh BH2QT95R9 cuts that chain short. For the service writer, this means quoting a firm price on the first call rather than padding estimates for hidden complications. For the tech on the floor, it means bolting on a component that aligns with the gear train without filing mounts or shimming brackets, keeping the job inside the booked hour.

Q1: What is the real-world failure pattern of these pumps in agricultural fleet use, and how quickly can I get a bulk shipment?
A: On Liuchai 2115 units operating in dusty conditions, we see bore scuffing becoming critical around the 3,500-hour mark. For bulk orders, our standard lead time is 15–20 working days, with expedited shipping options available for urgent bay stocking.

Q2: Are these pumps ready to run straight out of the box, or do I need to recalibrate the fuel delivery for my specific application?
A: The unit is factory-set to the standard 37 kW curve at 2400 RPM. However, we always recommend verifying the static timing against your engine serial number before installation to account for any prior modifications.

Q3: How does this replacement pump affect fuel consumption compared to a worn OEM unit?
A: A worn pump typically over-fuels to compensate for internal leakage, which masks poor atomization. This new unit restores the correct hydraulic pressure wave, which generally brings fuel consumption back to the original OEM specification-reducing operating costs for your customer.

Q4: I service both Liuchai and YuChai engines-will I need different drive couplings or adaptor plates?
A: No. This 2QT55 shares the standard SAE mounting interface common to the 2115 family. The same drive coupling fits both engine brands, so you can stock one pump and apply it across multiple jobs without additional adaptor purchases.

Q5: What warranty terms apply to workshop purchases, and do you offer core exchange programs?
A: We provide a 12-month workmanship warranty from the date of installation. Core exchange programs are available for qualifying workshops; please contact our trade desk to set up a return credit arrangement.
