It should not be necessary to detach the timing cover or to dismantle the engine further than the removal of the cylinder head and barrel in the course of ordinary service, but the following points should be noted if the engine is completely stripped. The timing gears are all marked for retiming purposes, so that by setting the gears so that the marks on the teeth register the timing will be correct.

To remove the magneto gear, undo the nut on the end of the armature, which will extract the gear from the taper. After the nut loosens, it will almost immediately tighten again and it is then that it commences to draw off the gear.
