Removal, dismantling, check, assemblage and axis installation коромысел, - engines SOHC
Removal
|
|
|
|
| 1. Disconnect a hose of system of ventilation картера. |
2. Turn out bolts (1), (2), (3) and (4).
|
|
Bolt (1), for assemblage deduction release, but leave wrapped on pair coils for assemblage fixing. Trying not to admit displacement of directing plugs, serially in stages release and turn out bolts (5) and (8). |
|
|
| 3. Cautiously turn out a bolt (1) and remove an axis коромысел in gathering. The removed assemblage lay on a workbench drainage apertures upwards, or lower in the bath filled with impellent oil. |
|
|
|
|
For the purpose of simplification of procedure of assemblage put removed components as their installation. |
Dismantle of assemblage of an axis коромысел
|
|
1. Turn out fixing bolts and remove from an axis коромысла, springs and support.
2. In case of need take from коромысел hydraulic proof-readers клапанных backlashes. If to take hydroproof-readers effort of hands it is not possible, take advantage of nippers, - try not to damage working surfaces of assemblages.
|
|
Hydroproof-readers it is necessary to take from коромысел only for replacement, or release of air stoppers. |
3. The removed hydroproof-readers place in an oil bath. |
|
Check
Hydroproof-readers клапанных backlashes
|
|
|
|
| 1. Attentively examine assemblages of hydraulic proof-readers клапанных backlashes, - presence of mechanical defects on working surfaces is not admissible. Faulty assemblages replace. |
2. Let the air out from assemblages of hydraulic proof-readers:
a) Having shipped the proof-reader in an oil bath, a round core in diameter about 2 mm wring out a valve ball;
b) Keeping a ball drowned, a finger of a free hand some times press on плунжер, - from assemblage should stop to leave air vials;
c) Take a core, then, quickly having pressed on плунжер, make sure that it not утапливается, otherwise replace assemblage of the hydroproof-reader. |
|
| 3. Having let out from the proof-reader air, again ship assemblage in an oil bath where it and should remain up to definitive installation on the engine. |
|
Коромысла a drive of valves
|
|
| 1. For the purpose of definition of a backlash of landing коромысел on the axis measure internal diameter of landing nests коромысел and subtract from it diameter of an axis. If the result of measurement falls outside the limits an admissible range (Specifications see), replace corresponding коромысло, or an axis. Replacement коромысел should be made according to marks of all elements of assemblage.
2. Restoration contacting to cams of a camshaft of working surfaces коромысел can be made by thin проточки. In the presence of deep defects, and also in case of strong deterioration коромысла are subject to replacement. |

| Label in the form of a letter "In" |
Label "+" |
Label in the form of a letter "In" (diameter of a label of 3 mm) |
Axis коромысел
Estimate a condition built in in one of the axis ends коромысел редукционного the valve. Whether check up the case of the valve is damaged and whether there are no signs of development of leaks through a ball, make sure of absence of extraneous subjects between spring coils. In case of need replace axis assemblage.
Assemblage
|
|
|
|
| 1. Having planted on an axis коромысла and support, establish assemblage on the regular place. At the first stage slightly tighten with identical effort bolts with (1) on (4) in an order specified in illustrations, - track, that apertures in axis support have coincided with directing plugs. Further make a tightening with demanded effort (12 Nanometers) bolts with (5) on (8). In last turn the definitive tightening with demanded effort (12 Nanometers) bolts with (1) on (4) (in a former order) is made. |
|
| 2. Establish covers of a head of cylinders and restore initial connection of a hose of system of ventilation картера. |
