5.2.32. Throttle case (Multec system)

Removal

Case of a throttle of system of injection of Multec fuel

A – nuts of fastening of the case of a throttle;

B – screws of fastening of the top part of the case of a throttle to lower

PERFORMANCE ORDER
1. Take off pressure in fuel system.
2. Remove the heater block.
3. Remove a weight wire from the accumulator.
4. Disconnect electric sockets from a fuel nozzle (squeeze out condense a telny ring of a rubber cover), from the step engine of management of air supply on turns of idling and from a potentiometer.
5. Mark and disconnect fuel hoses. Close the ends of hoses suitable traffic jams.
6. Disconnect vacuum tubes and hoses from the throttle case.
7. Disconnect draft of management of a butterfly valve from the throttle case.
8. Unscrew two nuts and remove the throttle case from an inlet collector. Remove laying of the case of a throttle (see rice. Case of a throttle of system of injection of Multec fuel).
9. If necessary unscrew two screws and remove the top part of the case of a throttle. At installation of the top part it is necessary to use new laying. Also if necessary unscrew unions of fuel-supply lines, but at their ustan ке use new sealing rings.

Installation

Adjustment of temperature of the air coming to the engine on system of injection of Multec fuel
 A – vacuum pipe;
B – hose of the valve of system of repeated combustion of exhaust gases;
C – pipe of control of the coal filter;
D – returnable fuel hose

PERFORMANCE ORDER
1. Installation is made in the sequence, the return to removal taking into account the next moments (see rice. Adjustment of temperature of the air coming to the engine on system of injection of Multec fuel):

– at installation use new laying and sealing rings, and also apply the means interfering their unscrewing on threaded connections;
– check work and, if necessary, adjust an accelerator cable;
– check correctness of connection of vacuum hoses and tubes;
– because there is no catcher of vapors of fuel, it is important that the vacuum hose of the sensor of pressure in a collector settled down horizontally on an extent from the sensor to the throttle case. At the same time hit of drops of fuel from the sensor or a hose to the inlet canal of the engine is prevented;
– check correctness of connection of fuel hoses. The hose of supply of fuel settles down from a fuel nozzle;
– include ignition and check existence of leak of fuel. In the presence of leaks eliminate them before start of the engine.
