Removal of air from a hydroregulator

1. The ball valve

2. Пруток

3. Плунжер

1. Remove cam-shafts (subsection see).
2. Prepare 16 pure plastic bags and number them from 1 to 16. It is possible to manage also a box with 16 branches.
3. Remove the first lever of a drive of valves, take from an aperture in a head of cylinders a hydroregulator and put in a bag together with the lever, observing working position of these details.
The prevention

The hydroregulator should be stored only in working position. At storage in horizontal or in the turned position in a regulator air which before assemblage is necessary for removing will get following recommendations stated in subitem 9 and 10 (see more low).

4. Remove from end faces of valves remote linings and directing disks, put these details in a bag with together hydroregulator.
5. Repeat actions it agree item 3 and get levers of a drive of valves, hydroregulators, remote linings and directing disks of other valves. Do not mix levers and hydroregulators, otherwise these details will be subject to the strengthened deterioration.

Condition check

1. Check up a surface of contact of the lever with a cam рапредвала, presence on this surface of wear tracks and damages. If levers are worn out, on cam-shaft cams the raised deterioration (subsection see) will be observed too. If necessary replace levers.
2. Check up presence of signs of the strengthened deterioration on hydroregulators and in the interfaced apertures in a head of cylinders. If there is a necessary measuring tool deterioration degree can be established by means of direct measurements. For this purpose measure internal diameter of an aperture under a hydroregulator in a head of cylinders and external diameter of a hydroregulator. The backlash is equal in a hydroregulator to a difference of these diameters. Compare the received size of a backlash with standard, specified in section (subsection see). If necessary replace the worn out details.
3. Check up presence of signs of deterioration on directing disks of levers, if necessary replace.


1. Before assemblage it is necessary to check up a thickness of each remote lining to define suitability for the further use. This operation is especially necessary in the event that new valves and saddles of valves or if valves were exposed to repolishing will be established. The procedure for test of a thickness of linings is described in subitem 2-5. If the head of cylinders was not exposed to repair and measurement of a thickness of linings is inexpedient continue assemblage, being guided item 8 and see further.
2. Establish directing disk of the lever of a drive on an end face of that valve from which this disk has been removed (it very important, item 13) see. Fix on a head of cylinders стрелочный the indicator, result a mobile probe of a leg of the indicator in contact with the persistent surface of a directing disk which are in contact to the lever of a drive of the valve. Establish an indicator scale on a zero.
3. Then cautiously lift a probe of a leg of the indicator and turn the indicator to strictly in parallel initial position. Result an indicator probe in contact with an end face of other valve on which the drive lever, i.e. the second valve from this the cylinder will operate.

The prevention

At turn the indicator should move to strictly in parallel initial position, otherwise indications will be erroneous.

4. Consider the indication of the indicator which will be equal to distance between an end face of a core of the valve and a persistent surface of a directing disk which the lever of a drive of the valve influences, write down this indication. To be convinced of strictly parallel moving of a display head in the course of measurement, turn a head back in initial position in which the indicator probe adjoins to a persistent surface of a directing disk. The indicator indication at return to initial position should be equal to zero. Repeat described above measurement for each pair of inlet and final valves of all cylinders. Results of measurements write down.
5. On the basis of the spent measurements define a suitable thickness of remote linings for each pair of valves. The thickness of a lining should be equal in accuracy to result of measurement, however the manufacturer establishes the admission in limits 0,025 mm.
The prevention

In spare parts linings with a thickness from 2,800 to 3,200 mm with step to 0,025 mm are delivered.

6. Value of a thickness is put on the bottom surface of a lining (for example, 2875 means a thickness in 2,875 mm), nevertheless, rather expediently to measure the valid thickness of a replaced lining by a micrometer as reduction of a thickness owing to deterioration is possible.
7. Establish remote linings on the corresponding valve, having tracked, that the surface with marks has been turned downwards.
8. If the thickness of a lining was not measured, establish directing disks and adjusting remote linings (are specified by arrows) on corresponding valves, having tracked, that the surface of linings with marks has been turned downwards.
9. Before installation of hydroregulators be convinced that in them there is no air. For this purpose press on плунжер a regulator (the regulator thus should be in vertical position, плунжер it is turned upwards), moving плунжера should not to be felt. If плунжер moves on more than 1,0 mm in a hydroregulator there is air. If hit of air in a regulator or if the new regulator air should be removed is established is revealed, having arrived as follows.
The prevention

On the working engine air from hydroregulators spontaneously does not leave. If regulators are established without removal got in air their normal work is broken and the raised noise will be listened.

10. Prepare the small vessel which sizes exceed the sizes of a hydroregulator a little, and пруток (for example a piece of a welding electrode) which passes in an aperture in плунжере a regulator. Fill a vessel with pure oil for the engine which mark corresponds filled in in the engine, ship a hydroregulator in a vessel with oil, observing vertical working position (плунжер it is turned upwards). Enter пруток into an aperture in плунжере and slightly press on the ball valve of a regulator (fig. Removal of air from a hydroregulator see). Keeping пруток in such position, slowly move плунжер upwards and downwards. Thus air will start to leave space under the ball valve. After the termination of an exit of vials from the top part of a hydroregulator release плунжер and get пруток then the ball valve will be closed.
The prevention

At отпускании плунжера keep the ball valve abroach.

11. Get a hydroregulator from a vessel and check up a course плунжера (item 9 see).
12. After removal of air from hydroregulators establish them in a head of cylinders on former places.
13. Establish on former places levers of a drive of valves, having paid attention to correctness of gearing of levers with hydroregulators and directing disks.
The prevention

The terminations of levers which enter into gearing with a remote lining and the directing plug differ on width. The lever termination from outside a remote lining slightly more widely than from outside аправляющей plugs. If the lever does not correspond to the given valve the lever termination will not come into a cut at an end face of the directing plug.

14. Establish cam-shafts (subsection see). Cam-shafts A head of cylinders
