Check of a gap of valves
The gap of valves is checked by the probe between a back part of a cam and a pusher.
| PERFORMANCE ORDER
| 1. To disconnect the elastic pipeline of ventilation of a case of the engine from a cover of a head of the block of cylinders.
| 2. To uncover the block of cylinders.
| 3. To turn a bent shaft of the engine for a nut of fastening of a pulley (it is impossible to rotate for a cam-shaft pulley) in the direction of its working rotation to situation in which both cams of the 1st cylinder will be turned by a working part of a cam up.
||4. To check a gap of valves of the 1st cylinder, inserting a probe plate between a back part of a cam and a pusher.
|5. To define type of the checked valve (inlet or final) and to compare value of the measured gap to the required value (see subsection 126.96.36.199.2). In case of need to adjust a gap of the checked valve.
The sequence of installation of valves, considering from a forward part of the engine (from the drive of system of gas distribution) in each cylinder it is identical: the first (about the drive of system of gas distribution) is the inlet valve, and the second – final.
|6. To repeat the described actions for valves of other cylinders in the sequence of injection (1–3–4–2, reading out drives of system of gas distribution from the party).
Adjustment of a gap of valves
Adjustment of a gap of valves consists in replacement of the adjusting plate located in deepening of a pusher. Replacement of adjusting plates does not demand extraction of a cam-shaft if the special device for performance of this operation is used.
Pistons of the engine should not be in process of replacement of plates of adjustment of a gap of valves precisely in VMT, and is several millimeters lower (about 1/4 turns of a bent shaft). It will prevent impact of the valve about a bottom of the piston pressed when replacing an adjusting plate.
| PERFORMANCE ORDER
| 1. To turn pushers so that in bottoms of pushers after compression it was possible to insert into cuts easily special nippers for extraction of adjusting plates.
||2. To establish a bent shaft of the engine in the relevant provision (see the description above) and by means of the press device (adaptation 21.106) to press down a pusher (opening at the same time the valve and squeezing its spring) so that by means of special nippers (21.107) it was possible to take an adjusting plate.
| 3. To measure thickness of the taken plate and, taking the measured gap and the required nominal size in attention, to pick up from a set a plate thickness providing the required valve gap.
|4. To insert the picked-up plate so that the surface with its designation was directed down (to a pusher).
|5. To take the press device.
|6. To repeat the described operations for other valves.
|7. To establish a cover of a head of the block of cylinders with new laying.
|8. To attach the elastic pipeline of system of ventilation of a case of the engine to a cover of a head of the block of cylinders.
