Application:
The 2643D640 fuel injection pump provides precise metering and
high-pressure delivery for Perkins T4.236 and AT4.236 turbocharged
diesel engines (4.0 L), widely employed in agricultural tractors
such as Massey Ferguson 265, 275, 290, 390T, 398; Landini 10000
Series; Fiat 640; combine harvesters including Massey Ferguson 750,
760, 850; White 8600 Series; generator sets by FG Wilson, KOHLER,
and Fairbanks Morse; and industrial machinery like stationary
pumps, compressors, and hydraulic power units driven by Perkins
T4.236 engines.
Technical specifications:
Pump type: inline plunger injection pump; number of plungers: 4;
maximum injection pressure: 2 050 bar; maximum fuel delivery: 125
L/h at rated speed; plunger diameter: 7.94 mm; cam ring diameter:
58 mm; drive interface: 12-tooth spline; fuel inlet port: 8 mm
BSPP; outlet fitting: M10 × 1; overall dimensions: 180 mm × 140 mm
× 95 mm; weight: 7.2 kg.
Material & performance features:
The pump housing is cast from high-strength aluminum alloy for
rapid heat dissipation, while the internal cam ring and plungers
are precision-machined from nitrided alloy steel for superior wear
resistance. Plungers receive a ceramic coating and operate in
ultra-smooth bores to minimize friction and withstand abrasive fuel
contaminants. Fluorocarbon seals resist degradation from diesel,
biodiesel blends, and common fuel additives. An integrated
mechanical governor in a stainless-steel chamber ensures stable
fuel delivery under transient load changes, and all external
surfaces feature a phosphate-based corrosion-inhibitive finish.
