9.4. A fuel broad tank

Before removal of a fuel broad tank remove protection of an arch of a back wheel.
The gravitational valve is not delivered as the separate spare part.
The valve remove through the top part of a bulk mouth.
Check the valve as follows. At valve installation in vertical position it is opened, and at an inclination on 45 ° – is closed.
At removal of a broad tank shift a connecting branch pipe, on топливоналивной to a pipe.


Fig. 5.1–1. A fuel broad tank: 1 – connection with "weight"; 2 – a fuel pipe from a fuel tank; 3 – a fuel pipe from a fuel tank; 4 – a fuel pipe from a fuel tank with white marks; 5 – a fuel pipe from the gravitational valve; 6 – a fuel pipe from a broad tank to the gravitational valve; 7 – the gravitational valve; 8 – a sealing ring; 9 – a fuel broad tank; 10 – a rubber cover of a mouth; 11 – a cover of a bulk mouth; 12 – a lining; 13 – a lock ring of a rubber cover of a mouth; 14 – a bolt, 10 Н·м; 15 – a drain hose; 16 – a connecting branch pipe; 17 – топливоналивная a pipe


Fig. 5.1–2. Connection of a "mass" wire (1) with a metal ring (2) on a filling pipe of a fuel tank



At installation of a fuel broad tank check up, that the tip of a wire of connection with "weight" 1 (fig. 5.1–2) has been reliably connected to a metal ring on a filling pipe of a fuel tank.
After installation of a fuel broad tank by an ohmmeter check up absence of resistance between a metal ring on a filling pipe of a fuel tank and "weight" of a body.
Otherwise check up, that the wire of connection with "weight" has been reliably connected to the negative plug of the storage battery
