5. Swinging arm and drive shaft: removal

  1. Remove the final drive housing. See Section 2 of this Chapter.
  2. Remove the exhaust silencer mounting nuts and unscrew its mounting Allen screws or bolts to withdraw the left-hand footrest plate. Similarly, remove the right-hand footrest plate complete with the rear brake components; if care is taken there is no need to dismantle the rear brake at all. On machines with disc rear brakes note that the fluid reservoir is secured to the battery carrier by a single bolt or nut.
  3. Disconnect the clutch cable from the operating lever and withdraw it from the gearbox housing.
  4. On the left-hand side of the gearbox housing slacken the large locknut and unscrew the swinging arm adjustable pivot stub.
  5. On the gearbox right-hand side remove its three retaining Allen screws and carefully prise out the swinging arm fixed pivot stub; if it proves stubborn, screw a suitably sized bolt into its centre thread and use a large pair of pliers to draw it out, rotating it to break the seal.
  6. With both pivot stubs removed, withdraw the swinging arm.
  7. Using a small screwdriver to ease the circlip at its front end over the gearbox output shaft splines, pull the drive shaft sharply backwards to remove it.
