Fuel feeding pump components

Components:
1 Drive rod: - length: 32,55 ÷ 32,65 mm
- measured protrusion A: 1,47 ÷ 2,07 mm
2 Gasket
3 Camshaft eccentric
4 Manual priming lever
Characteristics:
when the control eccentric rotates at 1000 r.p.m. minimum delivery is
73 l/h while self-regulation pressure is 0.5 ÷ 0.7 bar.

Piston fuel lift pump (on request)

Characteristics:
when the control eccentric rotates at 1000 r.p.m. minimum delivery is
65 l/h while self-regulation pressure is 1.5 ÷ 2.5 bar.
Important
The drive rod and its protrusion do not change in relation to the
diaphragm pump.

INJECTION PUMP

The injection system consists of a single-body pump with plungers
featuring constant stroke and feeding one cylinder each.
The pump, mounted on the crankcase is directly operated by the
camshaft.
Speed governor, extra fuel and stop device are separate from the pump
(see pages 48, 49, 50 and 78).
