-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
