Ensure absolute cleanliness during the operations that follow.

- Place the solenoid valve assembly in a vice fitted with protective jaws.1. Undo the control unit fixing bolts.

- Fit the tool for removing the control unit as follows:

Tool	Description	Function	Validity
2000017800	Removing-refitting kit	Robotized gearbox control unit - removing-refitting robotized gearbox control unit	1.3 Multijet MTA

1. Tighten the studs in the control unit fastening openings.2. Fit the reaction plate and secure it to the studs usign the nuts.3. Fit the extractor (3a) and tighten the bolt to disconnect the control unit (3b) from the solenoid valve contact plates.

Only use the special tool for removing the control unit.Never use other tools, for example, such as screwdrivers, for leverage and raise the control unit as the operation of the valve assembly and the actual control unit could be seriously adversely affected.

1. Undo the bolts (1a) and remove the bracket (1b).

1. Undo the bolts (1a) and remove the pressure sensor and valve retaining plate (1b).

1. Remove the even (1a) and uneven (1b) gear engagement solenoid complete with inner O-ring seals manually.2. Remove the outer O-ring seals.

Only extract the solenoid valves manually and not using tools.Use a cloth to overcome the resistance due to the presence of the O-rings.

Refitting ( Removing

) - Check that the valve body and the valves themselves are perfectly clean.1. Fit new outer O-ring seals for the even and uneven gear engagement solenoid valves on the valve assembly mounting.2. Place the even and uneven gear engagement solenoid valves in their seats complete with inner O-ring seals.

The projections (a) should coincide with the special housings in the valve assembly support.

1. Place the new pressure sensor and valve retaining plate in position.

The retaining plate should be fitted with the projection (a) facing upwards and towards the operator.

2. Place the new bracket (2a) in its housing and secure it by tightening the bolts (2b) to the recommended torque.

- Check that the solenoid valve contact plates are correctly positioned.

Use the studs for tool no. 2000017800 for centering in order not to damage the solenoid valve contact plates whilst fitting the control unit

- Place the studs for tool no. 2000017800 in the control unit fastening openings.1. Partly tighten the studs in the four openings in the control unit mounting.2. Press fit the control unit on the solenoid valve contact plates.- Undo the studs and remove them.- Fasten the control unit tightening the bolts to the recommended torque in a cross sequence.
