Check the extension of the pin over the crankshaft
Special tools and workshop equipment required
t  Depth gauge
Checking sequence
–  Checking using the depth gauge, the extension -a-of the pin with the generator star -1- removed.
1 - Generator wheel:
2 - Plug
3 - Pin extension -3- of the crankshaft a = 2.5... 3.0 mm
  V13-1201
Sender wheel: Installing and removing:
–  Every time that the bolts loosen themselves -1- , it is usual to replace the generator wheel -2-. Tightening torques: 10 Nm + 1/4 turn (90°) further
  Note
After a second assembly, the countersunk bolts holes are so deformed that the heads of the bolts -arrows- make contact with the crankshaft -arrows- and the sender wheel remains loose.
