Solenoid Coupling, Removing And Installing: Installing
Replace the O-ring after removing.
-- Lay the O-ring -arrow- in the groove on the supercharger housing.
-- Place the driver -2- on the solenoid coupling -1-.
-- Place the trim -3- on the solenoid coupling and secure with three bolts -4-.
-- Insert the :T40302 in the drive plate and the solenoid coupling.
- The drive plate is centered to the solenoid coupling.
-- 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.
- With the power supply switched on the drive plate is secured on the solenoid coupling.
Pay attention during the assembly that the solenoid coupling current feed with the :VAS6909 is not interrupted.
Interrupting the solenoid coupling current feed with the :VAS6909 may only take place when the clamping hub clamping bolts secured on the shaft.
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.
-- Remove the :T40302 with the power supply switched on.
-- Check that the coil spring -1- is seated correctly in the driveshaft -2-.
- The driveshaft must be free of oil and grease.
The following marks help with the allocation of the solenoid coupling driver to the supercharger shaft:
- Position the solenoid coupling drive plate so that the groove -4- for the coil spring alights with the arrow marking on the trim -3-.
- Position the supercharger so that the coil spring -2- points to the mark "KEY" -1-.
-- Place the solenoid coupling drive plate -1- on the supercharger shaft -2- -arrow-.
-- With the power supply still switched on place the solenoid coupling on the supercharger and tighten the bolts -arrows-.
-- With the power supply still switched on push the belt pulley by hand downward to the supercharger in direction of -arrow A- and at the same time tighten the clamping bolt -arrow B-.
-- Switch off the power supply, remove the :VAS6909 from the solenoid coupling and from the power source.
-- Install the coolant pipes to the supercharger. Refer to COMPRESSOR COOLANT PIPES, REMOVING AND INSTALLING .
-- Adapt the solenoid coupling after removing and installing or replacing:
- The Vehicle Diagnostic Tester is connected.
-- Select the mode.
-- Press the Go To button and select the "Function/component selection" and the following tree structures one after the other:
- 01 - Engine, OBD-capable systems
- Functions
- 01 - Supercharger clutch adaptation
