Removal

PERFORMANCE ORDER

1. Remove the butterfly valve case.
	2. On the ADR engine (Motronic 3.2) remove a fuel collector and disconnect a water tube (And) and a hose from a broad tank (In), located over an inlet collector.
3. Disconnect vacuum and air hoses from an inlet collector. Disconnect connection sockets.
4. Remove fastening of a rope of an accelerator from the top section of an inlet collector and disconnect hoses and wires from an air zaslonka if it is necessary (See fig. Elements of the top section of an inlet collector on the engine AAR, AAN and Elements of an air zaslonka on an inlet collector (ADR engine)).
5. On the AAR engine (KEIII Jetronic) remove the top section of an inlet collector.
6. Gradually turn off fixing bolts and remove an inlet collector or its bottom section (See fig. Elements of the bottom section of an inlet collector on the engine AAR, AAN).
