Replacing sender wheel
–  Always replace the sender wheel -2- after releasing the bolts-1-.
  Note
t  The sender wheel must be replaced, because with the first tightening of the wheel-crankshaft securing bolts, the base of the seating wheel becomes deformed, and if tightened a second time, or (installation) the conical base of the bolt -3- would not be supported in the wheel, but on the head of the bolt, on the crankshaft -arrows-.
t  Installation of the sender wheel is only possible in an installation position, given the position of the holes.
