WESPC 9520A313G Diesel Fuel Injection Pump for Perkins 1104D Engines - 13mm Plunger, 1900 Bar Pressure

WESPC 9520A313G diesel fuel injection pump engineered for Perkins 1104D-E44TA and 1104D-E44T electronically controlled turbo-diesel engines. This precision component delivers optimal fuel metering for superior engine performance across demanding applications.

Designed for Perkins 1104D-E44TA and 1104D-E44T electronically controlled turbo-diesel engines (4.4 L, 4-cylinder) powering:

• Massey Ferguson 7724 S Dyna-VT and 7726 S Dyna-VT tractors
• Landini Rex 5-120/130/145 T-V ROW-CROP machines
• JCB 437S AGRI wheeled loaders and 540-180 Hi-Viz telehandlers
• FG Wilson P55-6 and Pramac GSW180P enclosed generator sets

These engines deliver 115-150 kW at 2,200 r/min while complying with EU Stage IIIA / EPA Tier 3 emission standards.

• Single-piece close-grain cast-iron monobloc construction
• 13 mm plunger diameter with 13 mm stroke
• Injection pressures up to 1,900 bar
• Internal vane feed pump supplies 260 L/h at 700 kPa
• Hydraulic automatic advance provides 12° crank-angle advance
• Static timing: 8° BTDC ± 1° with ± 3° fine adjustment
• FKM (Viton) seals rated for biodiesel blends up to B20
• Operational temperature range down to -45°C

• Plunger and distributor rotor: vacuum-remelted 20MnCr5 alloy steel
• Carburised to 1.4 mm effective case depth
• Super-finished to 0.06 µm Ra surface roughness
• Cam-ring lobes induction-hardened to 65-69 HRC
• Roller tappets with DLC coating reduce friction by 50%
• Aluminium governor sleeve with PTFE-impregnated bore
• IP67-rated electronic fuel-stop solenoid housing
• Integral viscous torsional vibration damper limits twist to
