  • Introduce the tool polygonal adaptor - U 40084- to the alternator pulley.
  • Introduce the the socket wrench XZN 1/2" M10 long point - SAT 1006/2 10L- -1- on the alternator axle.
  • Loosen the screw joints turning to the right (immobilising the axle with the polygonal spanner).
  • Hold the poly-V belt free wheel pulley and turn the alternator axle until the pulley can be removed.

Installing

Installation is carried out in the reverse sequence; note the following:

  • Bolt the poly-V belt with freewheel pulley onto the alternator axle (screw in by hand until the stop).

To install the poly-V belt freewheel pulley, the torque wrench - SAT 8010- must be adapted as follows:

  • Release the socket -1- and remove it from the handle -2-.
  • Turn the handle -2- of the torque wrench 180º and place the socket.
  • Set turning direction of torque wrench to anti-clockwise on socket drive.

  • Introduce the the socket wrench XZN 1/2" M10 long point - SAT 1006/2 10L- -1- on the alternator axle.
  • Use the polygonal adapter - U 40084- tool to immobilise the axle.
  • Tighten the Poly-V belt pulley without freewheel sprocket: In order to do this, turn the alternator shaft to the left using the torque wrench - SAT 8010- .
