Service of yokes, their axes and hydraulic pushers
|
|
For performance described below works be required a micrometer and a nutromer. |
Removal
|
|
Turn a cranked shaft, having given the engine the provision VMT of the end of a step of compression of the first cylinder. In this situation the label on a pulley of a cranked shaft will be combined with the index on a cover of a gas-distributing belt, and the begunok of the distributor will turn a nouse towards an arrangement of the VV plug of a wire of a spark plug of the first cylinder.
Remove an air purifier.
Liberate VV candle wires from clamps on a cover of a head of cylinders.
With a spiral order, moving outside inside, give screws of fastening of a cover of a head of cylinders on a head. Uncover.
In stages weaken bolts of fastening of axes of yokes and carefully take assemblies of axes. Lay assemblies as their installation on the engine.
For fixing of pushers of valves in the engine put on their top parts rubber bandages, then remove directing pushers from a head of cylinders.

|
In order to avoid hit in hydraulic pushers of air do not overturn them and strongly do not incline. |
Dismantling and condition check
|
|
Partially disassembled assemblies of yokes, their axes and pushers are presented on an accompanying illustration.
|
|
Axes with one label should be established in a lobby directing pushers, with two - in back. The scheme of an arrangement of yokes on axes is clear from an illustration. |
Give bolts of fastening of axes of yokes. Check a condition of axes, remove from them the revealed agnails and the teases, capable to cause damage of landing nests of yokes in the course of removal of the last.
Remove yokes from the axes, putting them as an arrangement on the engine.
Check axes on existence of signs of wear and damages. By means of a micrometer measure diameters of axes. Compare results of measurements to standard requirements (see size tables and adjustments at the end of the Management). Replace excessively worn-out axes.
Check a condition of landing nests (openings) of yokes. In case of suspicions in excessiveness of wear measure internal diameters of nests. Compare results to data of size tables and adjustments. Replace worn-out yokes.
Check all pushers on existence of signs of operation, special attention giving to the surfaces contacting to yokes. Excessively worn-out pushers are subject to replacement.
|
|
In case of detection of excessive wear of a pusher it is necessary to check carefully a condition of a working ledge of the corresponding cam of a camshaft. |
Serially wring out a top of each of hydraulic pushers. If the plunzher is wrung out more deeply than on 1.0 mm, it is necessary to replace a pusher. Further check of pushers can be made after assembly by 10-minute turning on of the engine with turns 1 000 in a minute. If in the course of this check characteristic noise are revealed, remove the components blocking access to pushers and repeat the first check. Replace all pushers, which plunzher утапливаются is deeper than on 1.0 mm.
By means of a micrometer check directing pushers on existence of signs of excessive wear. Measure internal diameters of openings and diameters of pushers corresponding to them. If calculated in a subtraction way from result of the first measurement of the second the gap exceeds stipulated in size tables and adjustments (see the Management end), replace the corresponding components.

Assembly and installation
Assembly and installation are made as it should be, the return to a dismantle order.
|
|
Make sure of passableness of all channels and openings.
Before assembly grease all components with pure impellent oil.
In a former order dress yokes on an axis from which they were removed. If in the course of dismantle adjusting labels and yokes were not put mixed, use the signs, illustrated on an accompanying illustration. Pay attention that directing pushers are marked and axes of yokes with one label should be established in a lobby directing.
|
|
Yokes on a design are asymmetric, - see an accompanying illustration. |
Establish hydraulic pushers of valves in directing and fix them there by means of rubber bandages.
Establish components in a head of cylinders, having tracked correctness of placement of yokes in deepenings of directing pushers. Tighten bolts of fastening of axes of yokes, while only by hand.
|
|
Track, that plunzher of all pushers and cores of valves appeared located on the center of working surfaces of yokes, and oil openings of yokes were turned towards klapanny springs. |
Make sure that the engine on - former is in the provision VMT of the end of a step of compression of the first cylinder. In case of need make correction of provision of a cranked shaft.
Tighten bolts of fastening of axes of yokes on back directing pushers with demanded effort.
Turn the engine on one turn in the direction of normal rotation so that the index on a cover of a gas-distributing chain appeared again opposite to VMT label on a pulley of a cranked shaft. Tighten with demanded effort all remained bolts of fastening of axes of yokes and a lobby directing.
Check serviceability of a condition and correctness of provision of laying of a cover of a head of cylinders. At the slightest doubts it is necessary to replace laying.
Establish a cover on a head of cylinders, screw screws and place a sealant. Moving on a spiral from the center outside, in stages tighten screws with demanded effort. Connect hoses of ventilation of the engine.
Establish an air purifier. Start the engine and check it on leaks.
