WESPC Diesel Engine 2641A067 Fuel Lift Pump For Perkins Engine Parts

Application:

The 2641A067 diaphragm-type mechanical lift pump is engineered for Perkins T4.236 and AT4.236 turbocharged diesel engines (4.0 L, 4-cylinder) that power Massey Ferguson 2400-, 3400- and 550-series tractors, MF 7200 combine harvesters, JCB 3CX backhoe loaders and 530-70 Loadall telehandlers, plus FG Wilson P22-6 and Pramac GSW85P skid-mounted generator sets. It bolts to the left-hand timing-gear cover and supplies filtered fuel to the high-pressure injection pump across engine speeds from 750 r/min idle to 2 400 r/min rated.

Technical specifications:

Cast-aluminium single-diaphragm pump delivers 95 L/h at 300 kPa and 2 000 r/min; inlet and outlet ports are 8 mm hose-barb fittings. Four-bolt SAE J744 size 1 flange (44 mm × 25.4 mm PCD) is actuated directly by the camshaft eccentric. Diaphragm diameter is 78 mm, stroke 5 mm, and the integral bypass valve limits pressure to 350 kPa. All sealing gaskets are FKM (Viton) for biodiesel compatibility up to B20 and ultra-low-sulphur diesel down to −40 °C.

Material & performance features:

Powder-coated cast-iron housing resists salt-spray and stone-chip corrosion; multi-layer fabric-reinforced nitrile diaphragm with PTFE facing ensures low swell and extended flex life. Induction-hardened medium-carbon steel lever and push-rod resist wear, while a stainless-steel return spring prevents sag in humid climates. A translucent sight-bowl sediment filter with 80 µm paper element traps water and debris, and the spring-loaded priming lever allows rapid manual bleeding after service. Lightweight, maintenance-free sealed bearings and quiet operation suit continuous-duty agricultural, construction and generator applications.
