KANGDA 2QT88 / BH2QT95R9 Fuel Injection Pump – Direct Fit For Jiangdong 2110

When a Jiangdong 2110-powered tractor or genset sits idle in the bay, the clock keeps running on lost labor hours and delayed client work. Most fuel delivery failures trace back to plunger wear or governor drift, and sourcing a replacement that fits right the first time cuts straight through that productivity bleed. This BH2QT95R9 pump, listed as 2QT88 in the KANGDA catalog, lands on your bench ready to mount-no adapters, no timing guesswork, no second shipping wait.

The pump carries a 9.5mm plunger diameter, 9mm stroke, right-hand rotation, and a mechanical governor calibrated to the Jiangdong 2110 2-cylinder diesel. Rated engine speed sits at 2600 RPM, output at 32 HP. Static injection timing comes preset at 23° before TDC. These aren't marketing numbers-they're the same figures the OEM bench uses for pass/fail judgement. For a service bay, that means you bolt it on, bleed the lines, and hand the keys back instead of chasing timing marks through a service manual.

This 2QT88 replaces the original injection pump across the Jiangdong 2110 series, widely found in 20-35 HP agricultural tractors, small combine harvesters, and stationary genset packages. It also swaps into certain HF 2105 engine configurations where the mounting flange and drive gear pattern match, though always confirm the governor lever orientation before committing. For a repair shop, stocking this single SKU covers two common engine families in your local farming or construction rental fleet-reducing the number of line items you need to carry while still answering most 2-cylinder diesel callouts.

The BH2QT95R9 addresses the usual failure modes: plunger barrel scuffing from contaminated fuel, delivery valve seat erosion, and governing spring fatigue that lets RPM hunt under load. Instead of chasing these individually and eating up bay time, the complete pump assembly replaces all wear-prone internals in one move. The hardened plunger geometry reduces the risk of bore deformation from fine abrasive particles-common in off-road equipment that runs on bulk storage fuel. Shops that pre-stock this unit report turning around fuel-related no-starts in under 90 minutes, compared to half-day rebuild attempts that often require a second tear-down.

Carrying a shelf of individual plungers, barrels, delivery valves, and governor springs ties up capital and still leaves you waiting for the one part you overlooked. The 2QT88 consolidates all those components into a single, tested assembly that moves quickly when a customer rolls in with black smoke or a no-start condition. At roughly 5 kg per box, shipping cost stays low, and the simple flange-mount design means even a junior tech can handle the swap under supervision. For a diesel parts wholesaler, this SKU offers steady turnover-farmers don't schedule breakdowns, but they do remember which supplier got them back in the field same day.

Q1: How many of these should we keep on hand for a typical agricultural service season?
A: Shops servicing 30–50 tractors monthly usually hold 3–4 units. Peak planting and harvest periods see faster turnover-restock lead time averages 10–14 days, so plan accordingly.

Q2: Does this pump arrive with the drive gear installed, or do we transfer the old one?
A: The 2QT88 comes with the drive gear keyway cut but without the gear itself. Transfer your existing gear using a puller-torque the retaining nut to the OEM specification for that engine.

Q3: Have these units been run on an actual Jiangdong 2110 test stand, or just bench-calibrated?
A: Every batch is sample-tested on a production-matching engine stand for delivery curve validation at 2600 RPM, not merely rack-calibrated.

Q4: What is the typical service life we can quote to a customer?
A: With clean fuel and regular filter changes, field data shows 6,000–8,000 operating hours before minor governor drift appears-well within competitive range for this class.

Q5: Return rate history on this model-any pattern to watch for?
A: Less than 0.7% return rate over the last 18 months. The few cases traced back to contaminated fuel scoring the plunger, not a manufacturing variance.
