Check of a backlash of valves
The backlash of valves is checked щупом between a back part of a cam and a pusher.
| PERFORMANCE ORDER
| 1. To disconnect from a cover of a head of the block of cylinders the elastic pipeline of ventilation картера the engine.
| 2. To uncover the block of cylinders.
| 3. To turn a cranked shaft of the engine for a nut of fastening of a pulley (it is impossible to rotate for a cam-shaft pulley) in a direction of its working rotation before position in which both cams of 1st cylinder will be turned by a working part of a cam upwards.
||4. To check up a backlash of valves of 1st cylinder, inserting a plate щупа 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 backlash to demanded value (subsection 18.104.22.168.2 see). In case of need to adjust a backlash of the checked valve.
Sequence of installation of valves, considering from a forward part of the engine (from outside a system drive timing) in each cylinder it is identical: the first (about a system drive timing) is the inlet valve, and the second – final.
|6. To repeat the described actions for valves of other cylinders in sequence of injection (1–3–4–2, considering from outside system drives timing).
Adjustment of a backlash of valves
Adjustment of a backlash of valves consists in replacement of the adjusting plate located in deepening of a pusher. Replacement of adjusting plates does not demand cam-shaft extraction if the special adaptation for performance of this operation is used.
In the course of replacement of plates of adjustment of a backlash of valves engine pistons should not be precisely in ВМТ, and on some millimetres more low (about 1/4 turns of a cranked shaft). It will prevent valve impact about a bottom of the piston pressed at replacement of an adjusting plate.
| PERFORMANCE ORDER
| 1. To turn pushers so that in cuts in bottoms of pushers after compression it was possible to insert easily special nippers for extraction of adjusting plates.
||2. To establish a cranked shaft of the engine in corresponding position (the description above see) and by means of the press device (the adaptation 21.106) to press downwards a pusher (opening simultaneously the valve and compressing its spring) so that by means of special nippers (21.107) it was possible to take an adjusting plate.
| 3. To measure a thickness of the taken plate and, taking in attention the measured backlash and the demanded nominal size, to pick up from the complete set a plate in the thickness providing the demanded backlash of the valve.
|4. To insert the picked up plate so that a surface with its designation has been directed downwards (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 a new lining.
|8. To attach to a cover of a head of the block of cylinders the elastic pipeline of system of ventilation картера the engine.
