Sender wheel: removing and installing
–  Renew sender wheel -2- each time the bolts -1- are loosened.
  Note
t  The second time the bolts are tightened, the contact point of the countersunk head, in the sender wheel, is deformed sufficiently to allow the bolt head to seat on the crankshaft -3--arrows-, thus allowing the sender wheel to remain loose under the bolts.
t  The sender wheel can only be fitted in one position; the holes are offset.
