WESPC Fuel Injection Pump 131017592 For Perkins diesel Engine

Application:

The 131017592 fuel injection pump is engineered as an aftermarket replacement for Perkins T4.236 and AT4.236 turbocharged 4.0 L diesel engines, ensuring precise high-pressure fuel delivery and timing across a wide array of applications. In agricultural service, it fits Massey Ferguson tractors 265, 275, 290, 390T, and 398 as well as Landini 10000 Series and Fiat 640 models, where consistent injection performance under heavy load and varying RPMs is essential. Combine harvesters such as the Massey Ferguson 750, 760, and 850 and the White 8600 Series depend on its exact metering to maintain efficiency and throttle response during long harvesting shifts. Perkins T4.236 generator sets built by FG Wilson, KOHLER, and Fairbanks Morse (60–100 kVA) utilize this pump to stabilize prime and standby power output with minimal smoke and improved fuel economy. Industrial machinery—including stationary pumps, air compressors, and hydraulic power units driven by T4.236 engines—relies on its robust design to reduce downtime and extend maintenance intervals.

Technical specifications:

The 131017592 pump is a four-plunger distributor-type unit calibrated to deliver up to 2 050 bar (29 700 psi) of injection pressure with a maximum flow rate of 130 L/h at rated speed. Its drive interface features a 10-tooth spline flange oriented for clockwise rotation, with standardized 8 mm fuel inlet and outlet ports compatible with high-pressure diesel lines. Overall dimensions measure approximately 210 mm in length, 165 mm in width, and 130 mm in height, and its nominal weight is 7.4 kg. Bench-calibrated to Perkins engine serial ranges 510 001–590 000, the pump incorporates a fixed mechanical advance of 5° BTDC at low idle to ensure optimal combustion timing and reduced emissions.

Material & performance features:

Housed in lightweight aluminum alloy for superior heat dissipation and strength, the 131017592 pump’s internal cam ring and plungers are precision-machined and nitrided to achieve wear resistance capable of withstanding high-cycle fatigue and abrasive fuel contaminants. Ceramic-coated plungers operate within ultra-smooth bores held to tolerances of ±0.01 mm, while fluorocarbon O-rings and seals resist degradation from diesel, biodiesel blends, and common additives. An integrated mechanical governor assembly enclosed in a corrosion-resistant stainless steel chamber regulates fuel delivery under load changes, and a phosphate finish on all external surfaces prevents rust during storage and installation.
