8.8.5. Block of valves

GENERAL INFORMATION

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.


Prevention

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


Block of valves
1. Oil pallet
remove a nutritious tube of okhladitelny liquid before removal of the oil pallet
2. 10 N of m.
3. Laying
always replace
4. Strut
establish on laying
5. Oil filter
establish an epiploon
6. Block of valves
7. 10 N of m.
8. I will corrode connection
establish together with a sealing ring
9. Sealing ring
always replace
10. Cap
remove a cap before removal / installation of the unilateral coupling
11. Sealing ring
always replace
12. Sealing ring
always replace
13. Transferring draft of the mechanical valve
the end with a fillet should be turned to the valve
14. Case of the main transfer
15. Epiploon
always replace
it is established in the oil filter
16. 5 N of m.
17. 8 N of m.
18. A feeding tube of a radiator of cooling liquid of an automatic transmission
the moment of an inhaling of fastening to the oil pallet of 80 N of m.
19. 10 N of m.

Identification

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

Dismantling / assembly

PERFORMANCE ORDER
1) establish sealing rings on a cap
2) establish a cap so that the rim was in a flute on a case

Prevention

Before removal / installation of the unilateral coupling, remove a cap from a case not to damage a cap and a sealing ring.


3) move the gear shifting lever in situation P
4) establish the mechanical valve up to the end in the block of valves
transferring draft And is specified by an arrow
5) tighten the restrictive screw B to 4 N of m.

Prevention

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


Installation
PERFORMANCE ORDER
1) establish the block of valves on a transmission case
2) connect the mechanical valve A and the gear shifting valve In
3) tighten all bolts diagonalno to 4 N of m.
(arrow A) 1 ball in diameter of 3 mm

(arrow B) 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 failed because of the burned-through frictional slips or excessively polluted cooling liquid. If cooling liquid still is rather pure, place all block of valves in cleaning solution and then dry up it a stream of the dry compressed air.

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

The form of a tray corresponds to a 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 in turn the valve and a spring and place them in a tray
2) uncover other party and repeat operation
3) establish a cover on a tray
4) ship all tray together with valves in cleaning solution. Dry up the compressed air. Do not use water, the rags leaving fibers at cleaning of elements of the block of valves

Assembly

Grease at installation all elements of the block of valves with liquid of an automatic transmission and check 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 openings, from where them removed.

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


Prevention

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


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