8.8.5. The block of valves

THE GENERAL DATA

The block of valves can be removed, without removing a transmission from the car. Replace the block of valves if it is polluted or damaged.

After installation of the oil pallet, fill in cooling liquid of an automatic transmission according to the specification.

---

The prevention

Do not start the engine and do not tow the car if the oil pallet has been removed or in a transmission there is no oil.

---

The block of valves

1. The oil pallet Remove a nutritious tube охладительной liquids before removal of the oil pallet 2. 10 Н.м. 3. A lining Always replace 4. Распорка Establish on a lining 5. Oil the filter Establish an epiploon 6. The block of valves 7. 10 Н.м. 8. I will corrode connection Establish together with a sealing ring 9. A sealing ring Always replace 10. Заглушка Remove заглушку before removal / by installation unilateral муфты

11. A sealing ring Always replace 12. A sealing ring Always replace 13. Transferring draught of the mechanical valve The end with a fillet should be turned to the valve 14. Carter of the main transfer 15. An epiploon Always replace It is established in the oil filter 16. 5 Н.м. 17. 8 Н.м. 18. A feeding tube of a radiator of a cooling liquid of an automatic transmission The moment of an inhaling of fastening to the oil pallet 80 Н.м. 19. 10 Н.м.

Identification

The code designation is squeezed out on a metal plate which should remain attached to the block of valves

Dismantling / assemblage

PERFORMANCE ORDER

1) establish sealing rings on заглушку 2) establish заглушку so that ободок was in a flute on картере The prevention Before removal / by installation unilateral муфты, remove заглушку with картера not to damage заглушку and a sealing ring. 3) move the gear change lever in position Р 4) establish the mechanical valve up to the end in the block of valves Transferring draught And is specified by an arrow 5) tighten the restrictive screw In to 4 Н.м.

---

The prevention

The lever From the mechanical valve should be pressed to the restrictive screw In at installation carrying out. At a screw twisting In the lever From the mechanical valve, keep the lever, pressing on it in an arrow direction.

---

Installation

PERFORMANCE ORDER

1) establish the block of valves on картер transmissions 2) connect the mechanical valve And and the gear change valve In 3) tighten all bolts диагонально to 4 Н.м. (Arrow) 1 ball in diameter of 3 mm (Arrow) of 5 balls in diameter of 6 mm Code designation (it is specified by an arrow)

Dismantling / cleaning

The block of valves is necessary for assorting only if the transmission has failed because of the burnt through frictional overlays or excessively polluted cooling liquid. If the cooling liquid still is pure enough, place all block of valves in cleaning solution and then dry up its stream of dry compressed air.

The tray, is used for storage of all valves, springs and screws of the block of valves.

The tray form corresponds to the form of the block of valves.

Not to mix elements of the block of valves at installation, they should be placed in a tray.

Spherical the valve it is possible to store in department for storage of bolts.

PERFORMANCE ORDER

1) remove a back cover, get by turns the valve and a spring and place them in a tray 2) uncover on the other hand and repeat operation 3) establish a cover on a tray 4) ship all tray together with valves in cleaning solution. Dry up compressed air. Do not use water, the rags leaving fibers at cleaning of elements of the block of valves

Assemblage

Grease at installation all elements of the block of valves with a liquid of an automatic transmission and check up ease of their course. The valve should fall under the weight.

The valve which are a little scratched it is possible to use repeatedly. It will not have an adverse effect on transmission work.

All elements of the block of valves should be absolutely pure.

The valve and a spring it is necessary to establish in the same apertures, whence them have removed.

Establish the valve and a spring on the one hand, and then establish a cover before to pass to the second party.

---

The prevention

Some springs of valves have the identical sizes. However they are not interchangeable, as have various values of maximum deviations.

---

Grease all sealing rings with a liquid of an automatic transmission before installation.
