#* Hold wheel parallel to the workbench and with a mallet tap the end of the spindle. This will cause the complete Dynohub unit to drop out. There is a shim washer between the cone and the armature, and it must be replaced when the hub is re-assembled. | #* Hold wheel parallel to the workbench and with a mallet tap the end of the spindle.

#* Unless it is essential to do so, the armature and magnet should never be separated. If they are to be separated, a keeper ring should be used as otherwise the magnet will rapidly lose its magnetism. Even a moment's separation will cause loss of magnetism and a spanner placed across the magnet is useless as a substitute for a keeper ring [now unavailable, so don't separate the parts -- John Allen]. To separate the magnet and the armature, ag hubhold the Dynohub unit in the left hand with the terminal plate across the palm. Then fit a keeper ring over the armature and lightly tap the keeper with the palm of the right hand. The magnet will then slide off the armature on to the keeper.

#* At this stage it is wise to test the armature with a test meter. If there is no reading on the test meter there is a break in the winding. If a test meter is not available, a battery and bulb may be connected as shown in the diagram, and if the bulb does not light a break in the armature winding is indicated. A second test is to disconnect the lead from one of the armature terminals and touch the outer edges of the armature with the bare lead. If the bulb lights, this indicates a short circuit. | #* At this stage it is wise to test the armature with a test meter. If there is no reading on the test meter there is a break in the winding.
