5.11. Assembly ("charging") and installation of gidronatyazhitel of chains

Fig. 5.6. A mandrel for assembly of a gidronatyazhitel of a chain

It will be required to you: the same tools, as for removal, dismantling of a gidronatyazhitel, and in addition special mandrel which sizes are shown in fig. 5.6.
Before assembly grease a plunger and the internal surface of the case with pure engine oil.
1. Clamp in a vice a mandrel in vertical position.
2. Install the case of a gidronatyazhitel on a mandrel.
3. Insert into the case a plunger against the stop of a lock ring of a plunger in a mandrel.
4. Insert a spring into a plunger and fill a natyazhitel with pure engine oil. Squeezing a spring, wrap a carving stopper. At the same time the lock ring of a plunger has to enter a pro-point on the case and hold a plunger from movement, i.e. the natyazhitel will "be loaded".
5. Remove a gidronatyazhitel from a mandrel.

Prevention
Do not press a plunger as in this case the lock ring of a plunger will leave a pro-point on the case, and a plunger — the case, i.e. the gidronatyazhitel will "be discharged".

If there is no mandrel for assembly of a gidronatyazhitel and there is no opportunity to make it, a natyazhitel it is possible to collect as follows.
1. Make a ring of a strip of metal 1,0 mm thick and about 15 mm wide. For this purpose it is possible to use a piece of a tape from an old tape collar.
2. Bend the cut-off strip in a ring which diameter is equal to the outer diameter of a plunger of a gidronatyazhitel.
3. Insert a plunger into the case of a gidronatyazhitel so that the lock ring on a plunger was established opposite to a pro-point in the case.
4. Insert the made ring into a gap between a plunger and the case and advance it deep into cases on depth of a ring pro-point in the case.
5. Turn the case and push a plunger down. At the same time the lock ring will move to the bigger diameter of a pro-point on a plunger and will enter a pro-point on the case, holding a plunger in the loaded state.
6. Take an assembly ring.

Note
The plunger has to act from the case at a size shown on a photo.

7. Fill in oil in the case, insert into it a spring and, overcoming its effort, tighten a stopper.

Prevention
Do not press a plunger not to "discharge" a gidronatyazhitel.

8. Oil pure engine the channel for a gidronatyazhitel in a head of the block of cylinders (a gidronatyazhitel of the top chain) or in a forward cover of the block of cylinders (a gidronatyazhitel of the lower chain) and install a gidronatyazhitel against the stop in the lever of a natyazhitel there, but, without pressing strongly a plunger the lever, in order to avoid "discharge" of a gidronatyazhitel.
9. Grease with sealant laying of a cover of a gidronatyazhitel, lay a noise-insulating washer in a cover, establish a cover into place and fix by bolts.
10. Turn out a stopper from a cover …
11.... and through an opening under a stopper press a suitable core (for example, the screw-driver) on a gidronatyazhitel, having moved it against the stop, and then release. Gidronatyazhitel "will be discharged", having pushed out a core, its case under the influence of a spring will rest against a cover — the chain will stretch. Screw a stopper in a cover.

Note
So the gidronatyazhitel who is not discharged" looks "...
… and so – "discharged".
