5.2.16. Fuel injectors of Multec of MW and Multec-S

MULTEC MBT

Removal and installation

PERFORMANCE ORDER
1. Release pressure from a power supply system, having removed the relay of the fuel pump and turning cranked engine kcal a starter within at least 5 seconds.
2. Disconnect a wire of the minus plug of the accumulator.
3. Unscrew pressure regulator from a fuel supply tube to release the remained pressure in system.
4. Disconnect sockets of connection of injectors, then remove wires from a fuel collector.
5. Disconnect a vacuum tube from pressure regulator.
6. Turn off two fixing bolts of a fuel collector (are specified by shooters a photo at the left), then lift a fuel collector so that it was possible to remove injectors (on a photo on the right – a detachment of the socket of connection of a fuel injector).
7. Remove a fixing clip (a photo at the left) a fuel injector, then remove it from a fuel collector (a photo on the right shooters specified sealing rings).
8. Injectors are not subject to repair and if they are faulty, they need to be replaced.
9. The fuel collector can be removed from the car if to disconnect two fuel hoses connected to a collector.
10. Before installation replace sealing rings on both parties of injectors.
11. Further installation is carried out upside-down removals.

MULTEC-S

Removal

PERFORMANCE ORDER
1. Execute the operations described in subsection 5.2.11, points 1-10.
2. Turn off fixing nuts and bolts and remove the top part of an inlet collector.
3. Close a pure rag inlet channels.
4. Clear the adjoining surfaces of the top and lower part of a collector.
5. Remove wires from a fuel collector.
6. Disconnect sockets of connection of injectors.

7. Remove the socket of connection of the sensor of provision of a bent shaft from an arm.

8. Remove a cap from a control branch pipe of pressure of fuel and release the remained pressure.
9. Turn off three bolts and remove a fuel collector from an inlet collector.
10. Remove clips of injectors and remove fuel injectors.

Installation

PERFORMANCE ORDER
1. Before installation of injectors oil sealing rings engine.
2. Pay attention to the correct provision of installation of injectors.
3. Installation is carried out upside-down removals.
