Like other pieces of machinery, a mechanical clock needs maintenance and an oil service to operate smoothly like any other machine with inter-moving parts. A clock that runs without oil can face permanent damage to its internal parts. A clock generally should be oiled every 1 to 2 years.To keep the clock in tip top condition it is recommended to take your mechanical clock to a clock specialist every 5yrs or so.Below are some points to prevent your wind up clock from not working correctly and to keep it running like new all year long.
Remove the case and familiarize yourself with the wind up clock. It is recommended to read the user manual to help you clarify the various points through which you can oil your clock.
Purchase an oil kit specially designed for oiling clocks and definitely do not use car oil on clock parts. Clock kits sometimes come with a cleaning agent and a small bush.Please clean the parts as directed by the instructions
Fill the narrow applicator provided with the clock kit up to a few millimetres. Carefully pour the oil through the narrow holes in the back of the clock. Squeeze the applicator one hole at a time for a small drop of oil drop. This is usually enough for any clock.
Oil the front of the clock with extreme care. The front holes are much smaller than the back ones. Do not oil the gears during this process; they need to stay dry to maintain an efficient working condition.
Pour oil in the large holes used for winding the clock. Because of their diameter they require double the oil than the smaller holes. Squeeze two drops per hole for a proper oiling. Place the clock back in its case.
One should also remember the cogs and wheels of the clock.Clock kits often supply a small brush similar to a small toothbrush so that oil can be lightly applied to the cogs.
Take special attention when oiling the leading edges of the pallets where they contact the escape wheel teeth. The pallets are usually at the top centre of the clock movement. Follow the linkage up from the pendulum through the crutch until you get to the first wheel that it comes in contact with. That will be the escape wheel and the pallets are the two metal fingers that rock in and out of the path of the escape wheel teeth.This is a very important part of a clock that needs lubrication.
Wind the clock by putting the key in the wind hole and turning it clockwise or counter clockwise depending upon the make of the clock. Consult the user manual to find out the exact direction.
Continue winding until you feel a certain resistance when moving the key forward. Do not push the key beyond this point as it has wound up to its maximum. Set the time.
