Installation
1. Install a NEW valve body gasket (52), spacer (48) and a NEW crankcase gasket (47).
2. Install spacer (53) and bolts (77) spacer fasteners. Tighten the bolts. Tightening torque 10 Nm.
3. Install the battery cover assembly (57).
4. Install bolts (58) And (59). Tighten the bolts. Tightening torque 10 Nm.
5. Place seven check balls in the valve body.
6. Carefully install the valve body while connecting the manual valve rod.
7. Make sure the traction (3) hand valve has engaged with the valve (2) and locking lever (1).
8. Install one bolt (M6x1 length 47.5 mm) into the center hole (1) valve body, finger-tighten the bolt.
Attention: since the sizes of the valve body mounting bolts are different, be careful when installing them.
9. Install, but do not tighten, the valve body mounting bolts. The bolt locations are shown in the figure.
Locations for valve body mounting bolts. 1 - М6х1 - 65.0 mm, 2 - М6х1 - 54.4 mm, 3 - М6х1 - 47.5 mm, 4 - М6х1 - 35.0 mm, 5 - М8х1 - 20.0 mm, 6 - М6х1 - 12.0 mm, 7 - M6x1 - 18.0 mm.
Note: (modifications) do not install the fluid indicator restrictor bracket and its mounting bolt yet.
10. Install the manual detent spring.
11. Install the manual detent spring bolt.
12. Install a fluid pressure switch.
13. Tighten the switch mounting bolts by hand.
Note: the valve body bolts are tightened in order "spiral", starting from the center. A different tightening order may cause the valves to malfunction.
14. Tighten the valve body mounting bolts in order "spiral". Tightening torque 11 Nm.
15. Verify that the manual detent spring is properly seated on the detent lever. Tighten the mounting bolt. Tightening torque 11 Nm.
16. Install the torque converter clutch lock-up valve with a NEW O-ring to the valve body.
