Removing the movement from the case.

Clock repairing generally involves two distinct areas - metalwork and woodwork. Even where the case is made of metal as in a carriage clock, the processes for the movement and case are still quite distinct. The first thing to do is to physically separate the movement from the case. The method of removing a movement varies considerably from one type of clock to another.

A quick examination will soon show whether the movement should be extracted complete with the dial and hands or whether the dial is fixed to the case. In the latter situation, the hands will need to be removed before the movement can be released. Never dismantle the movement with the mainsprings wound - they have a lot of energy stored in them and can be dangerous to you and the clock. Do not undo any part of the movement without reading the section entitled 'Letting down mainsprings'.

Hand removal: There are three basic methods by which clock hands are retained:-

Pin & Collet

Threaded hand nut

Friction fit
