and make sure that the correct ribbed belt will be installed.

Ribbed belt allocation. Refer to the Parts Catalog.

Decoupler Differences
-A- small decoupling belt pulley with freewheel, special tool to be

used -T10474-

-B- large decoupling belt pulley with freewheel, special tool to be

used -3400-

Note

The ribbed belt for the large decoupling belt pulley with freewheel

must be longer, because the decoupling belt pulley with freewheel

has a larger diameter and it is different for vehicles with and with‐

out an A/C system.

Removing
– Remove the Generator - C- . Refer to

belt pulley with freewheel.

– Install the -T10474- or -3400- -1- in the belt pulley and attach

a wrench (SW 17).

– Install the -VAG1603A/1- -2- in the generator shaft.
– Turn the generator shaft clockwise to loosen and while doing

so counterhold with the wrench.

– Hold the decoupling belt pulley with freewheel in place by hand

and turn it at the generator shaft until the decoupling belt pulley

with freewheel can be removed.

Installing
Install in reverse order of removal. Note the following:
The -VAG1332- must be rearranged for installing the decoupling

belt pulley with freewheel as follows:

– Release the insert -1- and remove it from the handle part -2-.
– Turn the handle part -2- of the torque wrench 180° and reinsert

the socket.

– Set the rotation direction of the torque wrench socket to “left”.
– Next, screw the ribbed belt pulley with freewheel by hand onto

the generator shaft until stop.

– Insert the -T10474- or the -3400- -1- into the decoupling belt

pulley with freewheel and attach a wrench.

– Install the -VAG1603A/1- -2- in the generator shaft.
