A different kind of service work

Yesterday I serviced a tower clock movement, it drives four dials in a tower in Stockholm.
It was made and installed in 1914 by G. W. Linderoth, they were well known makers of tower clock movements and had customers around the world.
The company was active between 1844 and 1963.

Dejligt med noget arbejde der ikke kræver lup, og briller.

On a serious note... you bring mig files and rags and grease (or oil)? What tools and oils do you use?

I released the 15 kilos weight in the ceiling and pulled it all apart, pushed out the bronze bearings and heated up Molykote DX with the bearings in it, they need to completely soak up the grease as the pressure on the pivots and bearings is massive from the cast iron and brass wheels. I pushed the bearings back in rotated 180 degrees to minimize wear.
Everything turns so slowly, except the escape wheel, so the lubrication must be perfect to avoid damage from the pressure put on the pivots and bearings.
Every 10th day it gets a full wind, but it is capable of running for 14 days after the service.

No oilers, only a can of Molykote DX and a set of socket wrenches and a large screwdriver.

It's running within 30 seconds a week, but I am sure it can do better.

I talked to the head master and with a little attention it will easily run for another hundred years.
