7-4 FUEL SYSTEM
When the fuel tank is mounted remote position from the engine, the height from the bottom of
the fuel tank to the fuel joint of the throttle body should be 500 mm and less .
The bottom of the fuel tank can be up to 400 mm below the throttle body .
Position the fuel tank carefully because, when it is low, fuel is not fed to the throttle body,
and when it is high, it can cause high pressure in the throttle body then fuel rich and high fuel
consumption .
When piping the fuel, the hose should be as short as possible and attention should be paid to
heat transmission, size, bending, and leakage at hose joints and so on .
Care should also be taken to prevent air lock and vapor lock . It is required that return piping to
the fuel tank from the fuel pressure regulator on throttle body .
7-5 POWER TRANSMISSION TO DRIVEN MACHINES
7-5-1 BELT DRIVE
Take the following notes into consideration .
* V-belts are preferable to flat belts .
* The driving shaft of the engine must be parallel to the driven shaft of the machine .
* The driving pulley of the engine must be in line with the driven pulley of the machine .
* Install the engine pulley as close to the engine as possible .
* If possible, span the belt horizontally .
* Disengage the load when starting the engine .
If no clutch is used, use a belt tension pulley or the like .
7-5-2 FLEXIBLE COUPLING
When using a flexible coupling, run out and misalignment between the driven shaft and engine
shaft must be minimized . Run out and misalignment tolerance are specified by the coupling
manufacturer .
