CLEANING AND ASSEMBLING WALL CLOCKS
Wall clock cleaning. If the watch mechanism is not very dirty, it is enough to clean it with gasoline, chalk and a brush. In case of severe contamination, a special cleaning compound should be used.

Pin holes for chocks; Oil holes and sockets should be completely smooth and clean. The chock is grinded in the form of a drill, cotton wool with crocus is wound on it and a nest is polished. Then chock polished cone, polished holes.

After cleaning the watch, do not touch the platters and wheels with your fingers. Steel flat parts after cleaning should be sanded, washed and otsinit, if on their planes there is corrosion.

Build wall clocks. The assembly of the wall clock begins with the fact that they put the platinum with the legs on a specially prepared stand. Then install the central wheel and both drums insert the rollers of the battlefield, wheels of the turn and the battlefield. After that, carefully impose another platinum. Tweezers are inserted into the holes of platinum shafts of drums and wheels. Assembling should be done carefully so as not to bend the axles of the wheels.

After the assembly of platinum should be secured with all the pins, and then check the slope of the wheels, rotating the drums of the course and battle. Then you should check if the wheels of battle are correctly assembled After that, insert the levers, the springs of the levers, the counting disk and check the operation of the combat mechanism.

Build a combat mechanism. For proper assembly of the combat mechanism, it is necessary that during a stop of a battle, the lifting protrusion of the hammer in no case touches the pin or the sprocket tooth. This contributes to an easier lifting of the hammer, since the wheel has time to acquire some speed before the lifting pin touches the protrusion of the hammer. The protrusion of the hammer must not touch the walls of the pin wheel. The stem of the hammer must be well polished to facilitate the operation of the combat mechanism. The lifting rod of the hammer in the shaft must be tightly fastened and the shaft must not have a large axial clearance. Leather or suede inserts on the hammers are fixed with wood glue. If the insert is worn out, then a new one should be inserted for the softness of the sound of a fight.

Between the point of incidence and a hammer stop combat second trigger wheel can be done before 3 / 4 turns. When the combat mechanism stops working, the pin of the second start-up wheel should stop against or near the tribe, windmill or half a turn from the working end of the two-armed unlocking lever. The wings of the windmill must be installed on the axis of the tribe tightly, in order to eliminate the possibility of slippage.

To properly install the pin co-leco during assembly, use a bridge located on the platinum; unscrewing it, you can move the pin wheel in the right direction.

In the combat mechanism, the following defects are encountered: the unlocking lever has not yet lowered, and the pin of the second start wheel slips past the end of the two-armed unlocking lever, and the clock strikes without stopping; The number of strokes is confused.

In these cases, it is necessary to pay attention to whether the counting disk and the counting lever connecting to it are correctly installed.

If the wind turbine sits weakly on its axis or is "small in size, this causes an accelerated clock fight. To eliminate the defect, either tighten the retainer spring more tightly, or increase the wind turbine by rivetting or soldering additional plates on the sides of the wind turbine, increasing its area, but it is better to make new blades.
Assembling a combat mechanism with a comb. For the correct assembly of the mechanism of the clock with a comb you need to pay attention to the following.
1. The axles must be tightly pressed into the levers.

2. A proper clearance must be provided to move the levers.

3. Before setting the dial, you need to check the correctness of the battle several times for all 12 beats. Before you cut or bend any of the details of the battle, you need to carefully check the entire mechanism and make sure that these operations are necessary.

4. The minute tribe on the axis of the central wheel should rotate quite tightly. If it is fixed loosely, then the tube of the tribe is compressed with round pliers.

5. If the tribe of the promissory note wheel or the hour wheel clutch rotates, it is necessary to secure them by pulling the punch.
After the final installation of the combat mechanism, the platinum pins are firmly fixed and the stroke mechanism is adjusted. Having started a little spring, set the course. The depth of the stroke with raids should be about a fourth of the thickness of the pallet. Moreover, the depth of the fall of both pallets should be exactly the same.
After assembly, lubricate the friction surfaces of the mechanism parts, including pallets. Then set the dial and hands. In wall and floor clocks, pins are mainly used as fasteners and installation parts. The pins are cylindrical, conical and cotter pins. To secure different levers in wall and other large watches, cotter pins are recommended. For other purposes, such as strengthening the dial, etc., fastening pins with a small taper are recommended. A pin with a large cone is held loosely in the hole.
