Removal, dismantling, check, assembly and installation of an axis of yokes, - SOHC engines
Removal
|
|
|
|
| 1. Disconnect a hose of system of ventilation of a case. |
2. Turn out bolts (1), (2), (3) and (4).
|
|
Bolt (1), for deduction of assembly release, but leave wrapped up on couple of rounds for assembly fixing. Trying not to allow shifts of the directing plugs, serially in stages release and turn out bolts (5) and (8). |
|
|
| 3. Carefully turn out a bolt (1) and remove an axis of yokes assembled. Lay the removed assembly on a workbench drainage openings up, or lower in the bathtub filled with motive oil. |
|
|
|
|
For the purpose of simplification of the procedure of assembly put the removed components as their installation. |
Dismantle of assembly of an axis of yokes
|
|
1. Turn out fixing bolts and remove from an axis of a yoke, a spring and a support.
2. In case of need take from yokes hydraulic proofreaders of valvate gaps. If it is not possible to take hydroproofreaders by effort of hands, use nippers, - try not to damage the working surfaces of assemblies.
|
|
Hydroproofreaders it is necessary to take from yokes only for replacement, or release of air traffic jams. |
3. The removed hydroproofreaders place in an oil bathtub. |
|
Check
Hydroproofreaders of valvate gaps
|
|
|
|
| 1. Attentively examine assemblies of hydraulic proofreaders of valvate gaps, - existence of mechanical defects on working surfaces is not admissible. Replace faulty assemblies. |
2. Let out the air from assemblies of hydraulic proofreaders:
a) Having shipped the proofreader in an oil bathtub, a round core with a diameter about 2 mm wring out a valve ball;
b) Holding a ball drowned, a finger of a free hand several times press a plunger, - assembly has to stop leaving vials of air;
c) Take a core, then, having quickly pressed a plunger, make sure that it does not utaplivatsya, otherwise replace assembly of the hydroproofreader. |
|
| 3. Having let out the air from the proofreader, again ship assembly in an oil bathtub where it also has to remain up to final installation on the engine. |
|
Yokes of the drive of valves
|
|
| 1. For the purpose of definition of a gap of landing of yokes on the axis measure the internal diameter of landing nests of yokes and subtract from it diameter of an axis. If the result of measurement exceeds the limit of admissible range (see Specifications), replace the corresponding yoke, or an axis. Replacement of yokes has to be made according to marking of all elements of assembly.
2. Restoration of the working surfaces of yokes contacting to cams of the camshaft can be made by a thin pro-point. With deep defects, and also in case of strong wear of a yoke are subject to replacement. |

| Tag in the form of a letter "In" |
Tag "+" |
Tag in the form of a letter "In" (diameter of a tag of 3 mm) |
Axis of yokes
Estimate a condition of the reducing valve which is built in in one of the ends of an axis of yokes. Whether check the case of the valve is damaged and whether there are no signs of development of leaks through a ball, make sure of lack of foreign objects between spring rounds. In case of need replace assembly of an axis.
Assembly
|
|
|
|
| 1. Having put on an axis of a yoke and a support, establish assembly on the regular place. At the first stage slightly tighten with identical effort bolts with (1) on (4) in the order specified illustrations, - track that openings in support of an axis coincided with the directing plugs. Further make tightening with the required effort (12 Nanometers) of bolts with (5) on (8). In the last turn final tightening with the required effort (12 Nanometers) of bolts with (1) on (4) is made (in a former order). |
|
| 2. Establish covers of a head of cylinders and restore initial connection of a hose of system of ventilation of a case. |
