KANGDA 2Q22 BH2Q80R8 – Direct-Fit Fuel Injection Pump For 295T-2 Engines

The KANGDA 2Q22 (model BH2Q80R8) serves as a mechanical inline injection pump precisely calibrated for the 295T-2 diesel power unit. Operating at a governed speed of 2200 RPM, this assembly is manufactured as a direct replacement component for Shandong Tractor (Shantuo) agricultural machinery. By delivering accurately metered fuel to each cylinder, the pump ensures proper atomization even when the equipment faces varying field loads.

Rated as a two-cylinder inline distribution pump, this unit incorporates a plunger with an 8 mm diameter. A cam lift of 8mm is featured by the BH2Q80R8 model, with a flange mounting method employed alongside a φ46mm positioning step. Thread specifications include M12×1.25 for the delivery valve holder, while the fuel return port is configured to M14×1.25. Lubrication is handled through either splash or force-feed systems, and the pump supports a maximum governed speed matching the 295T-2 engine's 2200 RPM rating. A BQ series governor is integrated as standard equipment to manage idle-to-load transitions.

Exclusive calibration for the 295T-2 two-cylinder diesel engine has been performed on this injection pump. Common applications include Shantuo (Shandong Tractor) equipment such as small and mid-sized tractors along with tillage implements. For workshops maintaining high-hour agricultural units or vintage diesel machinery, this component (Order No. 2Q22) is particularly relevant, as original fuel pressure must be preserved to avoid power degradation during operations like plowing and hauling. Generic pump models lack the factory tuning that aligns injection timing with the 295T-2's 2200 RPM power band.

Alignment of the gear timing marks must be performed with care during installation to prevent engine knocking. Any dirt on the flange mounting surface should be removed prior to fitting; fixing nuts ought to be torqued to 94-101 ft-lbs (13-14 kg-m) according to standard diesel assembly practices. Before mounting, inspection of the delivery valve is recommended, and lubrication of the plunger barrel with clean diesel fuel should be carried out. Once installed, a static timing check becomes mandatory-rotation of the flywheel to the specified mark and confirmation of the fuel spill timing are required steps. Cross-threading of the M12x1.25 connections can be avoided by carefully transferring existing high-pressure pipes when performing aftermarket replacements.

Though this is a mechanical unit, its precision rivals that of common rail systems in terms of fuel delivery accuracy. Extended pump life-beyond 8,000 operating hours-can be achieved through periodic inspection of the plunger and barrel for signs of scoring or wear. For repair facilities, keeping the BH2Q80R8 unit (2Q22) in inventory provides an immediate answer to complaints about hard starting and sudden power loss, both of which frequently affect aging agricultural fleets. Fuel quality also influences service intervals; water separator drainage should be performed routinely to protect internal components from corrosion.

Q1: Is the BH2Q80R8 suitable for non-turbo 295 engines?
A: Direct interchangeability applies only to the 295T-2 variant. Non-turbo models may exhibit timing discrepancies, so verification of the nameplate for 2Q22 is strongly advised before purchase.

Q2: Which symptoms suggest imminent pump failure?
A: Persistent white smoke during cold starts, inability to reach 2200 RPM under load, uneven idling, and noticeably higher fuel consumption all point toward worn internal plunger components.

Q3: Are special tools mandatory for timing this pump?
A: While the flange mounting ensures basic alignment, use of a dial indicator is recommended for precise spill timing. Skipping this step often leads to incomplete combustion and potential valve damage.

Q4: What fuel specifications protect this pump's longevity?
A: Diesel with a cetane rating of 45 or higher is advised. Frequent water separator checks are equally important, as contaminated fuel ranks as the leading cause of premature plunger wear.

Q5: Does heavy agricultural use affect warranty coverage?
A: Manufacturing defects remain covered, though the plunger and delivery valve are treated as wear items subject to normal consumption, similar to piston rings or bearings.
