3.3.4.17. Adjustment of backlashes of valves

THE GENERAL DATA

Numbering of cylinders and connections of high-voltage wires

Arrangement of valves

Adjustment of inlet and final valves should be made at the cold engine at temperature between 20 ° and 40 ° S.Velichina клапанных backlashes is very important for achievement of optimum working indicators of the engine. If the backlash is too great, valves will not open sufficiently, also they will open late and to be closed early. If the backlash is too small, valves will not be closed completely that will lead to a lack of a compression and very fast обгоранию valves and saddles of valves.

Adjustment of backlashes of valves

During adjustment of backlashes of valves to turn a cranked shaft only on an engine course, rotation to make, having established a key on a pulley bolt.

PERFORMANCE ORDER

1. To turn a cranked shaft, to combine a label on a pulley коленвала with a label in shape "About" on a drive cover. 2. At a lung качании a pulley forward and it will be appreciable back that valves of the cylinder №1 or №5 shake (two levers of the valve move in opposite directions). If valves of the cylinder №1 shake, to turn a cranked shaft on 360 ° that valves of the cylinder №5 shook. 3. Having achieved the necessary position of valves of the cylinder №5, to check up backlashes of valves of the cylinder №1 for what to establish щуп this or that thickness between the lever of the valve and a valve rod. If it is required to adjust a backlash, to turn the adjusting screw of the lever of the valve, the necessary size of a backlash will not be reached yet. Backlashes of inlet and final valves have various size. 4. Now, if to turn a cranked shaft on 1/3 turns, valves of the cylinder №3 will shake, and it is possible to check up and adjust backlashes of valves of the cylinder №4. 5. To make adjustment of backlashes as ignition in cylinders as follows (see the table). On fig. Numbering of cylinders and connections of high-voltage wires the order of numbering of cylinders is shown: numbering of valves is given regularly, since a forward part of the engine (fig. the Arrangement of valves see). 6. To establish linings of covers клапанного the mechanism and to establish covers клапанного the mechanism. To tighten fixing bolts according to the inhaling moment.
