8.8.5. Block of valves

GENERAL INFORMATION

The block of valves can be removed, without removing the 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 the 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 the transmission there is no oil.


Block of valves
1. Oil pallet
pick up the nutritious phone of cooling 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. The transferring draft of the mechanical valve
the end with a fillet has to be turned to the valve
14. Case of the main transfer
15. Epiploon
always replace
is established in an oil filter
16. 5 N. of m.
17. 8 N. of m.
18. The feeding tube of a radiator of cooling liquid of the automatic transmission
the fastening inhaling moment 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 has to 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) install the mechanical valve up to the end in the block of valves
the 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 has to be pressed to the restrictive screw B when carrying out installation. When twisting the screw B of the lever From the mechanical valve, hold the lever, pressing on it in the direction of an arrow.


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

(arrow B) of 5 balls with a diameter of 6 mm
code designation (it is specified by an arrow)

Dismantling / cleaning

The block of valves needs to be disassembled only if the transmission failed because of the burned-through frictional slips or excessively polluted cooling liquid. If cooling liquid is still rather pure, place all block of valves in the cleaning solution and then dry up it a stream of 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 on the other hand and repeat operation
3) establish a cover on a tray
4) ship all tray together with valves in the cleaning solution. Dry up compressed air. Do not use the water, rags leaving fibers when cleaning elements of the block of valves

Assembly

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

The valve which are a little scratched it is possible to reuse. It will not have an adverse effect on operation of the transmission.

All elements of the block of valves have to be absolutely pure.

The valve and spring it is necessary to establish in the same openings from where they were 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 interchanged as have various values of tolerances.


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