9.11. Check and adjustment of turns of idling

GENERAL INFORMATION

For check and adjustment of turns of idling it is necessary to use a tachometer working at a photo cell. The tachometer should react to light reflected by an aluminum foil of pasted on a pulley of a cranked shaft.

Gap measurement between the adjusting screw and a control lever of the fuel pump on the engine of 1,7 l

Gap adjustment
For adjustment of a gap weaken a lock-nut and rotate the adjusting screw.

PERFORMANCE ORDER
1. Warm up the engine to working temperature, check turns of idling and cool the engine.
2. On the cold engine check a gap between the screw of adjustment and a control lever of the fuel pump. At temperature of cooling liquid 20°С the gap should be in limits from 0,8 to 1,1 mm. For adjustment of a gap weaken a lock-nut and, rotating the adjusting screw, establish a demanded gap then establish a lock-nut (see fig. Gap measurement between the adjusting screw and a control lever of the fuel pump on the engine of 1,7 l, gap Adjustment).
3. Start the engine and check idling turns. If turns of idling differ from demanded, weaken a lock-nut and, rotating the adjusting screw, establish demanded turns then tighten a lock-nut.
4. Warm up the engine and check idling turns. In the course of engine warming up the gap between the adjusting screw and a control lever of the fuel pump should decrease gradually before complete contact of the screw to the lever. Otherwise there is a damage to system of cold start of the engine, and it is necessary to make repair at a maintenance stage.
