Dismantling and assembly of the electrohydraulic control unit

Dismantling

Dismantling and assembly of the electrohydraulic control unit

16 — Plastina of gear shifting
17 — Clamps
17a, 17b — Bolts
Y3/6 — the Electrohydraulic control unit
Y3/6/y1 — the Electromagnetic valve of adjustment of pressure of adjustment
Y3/6/y2 — the Electromagnetic valve of adjustment of pressure of gear shifting

Y3/6/y3 — the Electromagnetic valve of inclusion of 1-2 and 4-5 transfers
Y3/6/y4 — the Electromagnetic valve of inclusion of 3-4 transfers
Y3/6/y5 — the Electromagnetic valve of inclusion of 2-3 transfers
Y3/6/y6 — the Electromagnetic valve of blocking the hydrotransformer


 PERFORMANCE ORDER

1. Uncover at the electrohydraulic control unit.
2. Turn off bolts (17a) and (17b) and remove clamps (17).
3. By means of flat-nose pliers, take all electromagnetic valves (Y3/6/y1) - (Y3/6/y6) from a plate (16).
4. Remove the electrohydraulic block (Y3/6) from a plate (16), - for removal of the block it is necessary to wring out clamps on a stiffening rib of the sensor of temperature of transmission liquid.

Assembly

Assembly is carried out as it should be, the return to dismantling.
