Removing the magneto from the machine

 

Tools required

  • If driven by a fixed pinion or sprocket, a suitable puller for removing it

  • Possibly one or more specially adapted tools for removing the nuts/screws securing the magneto's mounting flange or base to the engine

 

Procedure

Remove the magneto from the machine following the instructions in your machine's service manual.

Tips:

If fitted with an automatic timing device (ATD) for advance and retard, undoing the ATD retaining screw more than a few turns should engage its self-extract mechanism, and a further turn of the retaining screw should release the taper.

If fitted with a fixed drive pinion/sprocket, a puller will be required. With some pinions/sprockets, a sleeve of the puller is screwed into the pinion/sprocket, and an extractor screw is then tightened against the end of the magneto drive shaft to release the taper. With others, a universal two-legged puller can be employed, or there may be provision for attaching a bridge puller. Resist the temptation to crowbar the pinion-sprocket off by levering against any mating surfaces of the timing chest.

With magdynos, it is, of course, also necessary to remove the dynamo and its drive train.

Some of fixing nuts/screws may be difficult to access and specially adapted tools may be required. If in doubt and your service manual doesn't help, ask on the appropriate web forum for your machine.
