-- Remove the first bolt -arrow-.

-- Remove the remaining bolts, to do so turn the solenoid coupling respectively ¹ /₃ turn further.

-- Remove the solenoid coupling -1- in direction of -arrow-.

Check the Sacrificial Liner and the Outer Friction Lining for Wear.

NOTE:

Before reinstalling a used solenoid coupling the sacrificial liner and the outer friction lining must be checked for wear. If new solenoid coupling is installed this step does not apply.

-- Place the caliper -1- as shown on the highest point on the sacrificial liner -2- and measure the distance -X- to the friction lining -3-.

Specified value: minimum 0.2 mm.

-- Perform the measurement all around on at least three locations.

-- If specified value is not reached, replace the solenoid coupling.

-- Place the drive plate -2- on the solenoid coupling -1- and install the :T40302 hand-tight.

-- With the feeler gauge -3- check the distance of the outer friction lining to the outer friction surface.

Specified value: minimum 0.2 mm.

-- If specified value is not reached, replace the solenoid coupling.

The driver is still placed -2- on the solenoid coupling -1- and the :T40302 is installed hand-tight.

-- Connect the :VAS6909 to a 12V battery or on the vehicle jump start terminal.

-- Connect the :VAS6909 connector with the solenoid coupling and switch on the power supply to the solenoid coupling.

CAUTION:

There is a risk of destroying the solenoid coupling.

The solenoid coupling must not be connected longer than 15 minutes to the power supply.
The current feed heats the solenoid coupling.

-- With the feeler gauge -3- on the position shown in the illustration check the distance from the clamping hub -shown in blue- to the outer friction surface in the energized state.

-- Perform this measurement on all three locations on the clamping hub.

Specified value: maximum 1.3 mm

-- If specified value is exceeded, replace the solenoid coupling.

-- Switch off the :VAS6909A .
