2Q18 BH2Q95R8 Fuel Injection Pump – Direct Fit For Shantui 2105 Diesel Engine

For the Shantui 2105 series diesel engine, the KANGDA 2Q18 BH2Q95R8 fuel injection pump offers a precision-built replacement engineered to maintain rated power delivery at 2400 RPM across agricultural and light-duty construction applications. This in-line distributor pump operates without electronic intervention, making it a dependable choice for workshops servicing mechanical diesel fuel systems still widely used in global field machinery. Direct interchangeability with the original factory unit guarantees that equipment returns to service with minimal calibration effort.

Delivering accurate fuel metering, the BH2Q95R8 is configured as a two-cylinder in-line injection pump with a 9.5mm plunger diameter and 8mm cam lift. Rotation is specified as left-hand when viewed from the drive flange, with a flange-mounted drive interface matching the Shantui 2105 engine housing. Governing is preset for 2400 RPM maximum engine speed, while delivery valve settings and fuel injection timing are factory-adjusted to align with the engine's natural combustion window. Hardened camshaft surfaces and precision-ground plunger barrels are incorporated to endure repeated mechanical stress without premature deformation.

This fuel injection pump is specified exclusively for power units built around the Shantui 2105 architecture-an engine frequently found in crawler bulldozers, compact wheel loaders, and row-crop tractors from the Shantui product line. Categorized under the BQ Pump family, the model BH2Q95R8 confirms correct engagement with the existing drive gear and mounting flange. Pressurization and timed delivery of diesel fuel to each cylinder depend entirely on this component, making it a frequently ordered service part for workshops maintaining older 2105-powered machines in both farming and earthmoving sectors.

Before mounting, the engine speed reference and top dead centre (TDC) of the Shantui 2105 must be verified, as alignment between the pump's internal timing marks and the engine camshaft gear directly affects starting behaviour. Replacing high-pressure fuel lines and delivery valve holders is advised when thread damage or seal degradation is observed, since any pressure loss compromises the diesel fuel system performance. After the unit is fitted, static timing should be rechecked using a dial indicator on the plunger stroke, with the 2400 RPM governed limit used as the final verification reference. Supply pump (lift pump) outlet pressure also requires inspection-restricted inlet flow often causes cavitation damage that shortens fuel injection pump service intervals.

Although common rail systems now dominate new engine production, the 2Q18 BH2Q95R8 continues to play an essential role in supporting pre-emissions machinery still active on job sites. Unlike VP44 or CP3 high-pressure pumps, which rely on sensitive electronics and are vulnerable to catastrophic failures from contaminated fuel, this mechanical BQ pump allows straightforward diagnosis and cost-effective rebuilding. Workshops with diesel injection repair capability can restore the BH2Q95R8 by fitting new plunger and barrel assemblies, replacing delivery valves, and recalibrating governor weights, recovering approximately 95% of original delivery accuracy. Exchange programmes for these mechanical units provide a budget-friendly path to keep older Shantui equipment productive, bypassing the expense of full engine replacement or electronic retrofitting.

Q1: Is the BH2Q95R8 pump compatible with a Shantui 2105 engine fitted in a TY180 bulldozer?
A: Compatibility depends strictly on the engine model rather than the machine type. If the equipment plate confirms Shantui 2105, the BH2Q95R8 will mount correctly. Models with larger displacement engines require different pump specifications.

Q2: Does the KANGDA unit arrive with the timing shim set included?
A: Each pump is shipped without shims, as the original engine's timing thickness varies by production batch. Reuse the existing shim pack or measure the protrusion height during installation to select appropriate shims.

Q3: What core return conditions do you accept for exchange orders?
A: Core units must have an intact housing and complete internal rotating group. Pumps with fractured flanges, seized camshafts, or missing delivery valve holders typically do not qualify for full credit.

Q4: How quickly can exchange pumps be dispatched to reduce bay waiting time?
A: Exchange orders placed before 12:00 (local warehouse time) are shipped the same working day. This stock strategy allows workshops to perform a same-day swap, avoiding the typical 3–5 day rebuild delay.

Q5: What symptoms indicate that the pump requires immediate attention?
A: Noticeable power drop at 2400 RPM, rough idling with speed hunting, or dense black exhaust under load point toward plunger or delivery valve wear. Continuing operation under these conditions risks complete engine shutdown.
