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

4) 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.
