Reposted from RWC, our lighter sister.
Completion of 2801 service: Cleaning, Lubricating, and Assembly. I am learning this process and prone to many mistakes but enjoy sharing anyway. Many will consider this kind of stuff boring but as I progress into more complicated movements I am more than happy to share my adventures as I learn some very basic watchmaking techniques.
Also I could not take pics of everything such as taking off shock assemblies, balance assembly cleaning, also the mainspring is new and so I left it alone, these things are tutorials unto themselves.
Parts are stored in basket and ready for cleaning.
Very inexpensive ultrasonic cleaner. I use L & R Watch Cleaning Solution and L & R Rinse Solution.
Tools for Oiling: The black oiler is used for almost all tasks.
Various types lubricants and grease. One Dip on the left for cleaning the balance.
Oil Tray.
THE AMOUNT OF LUBRICANT PICKED UP ON THE OILER IS THE AMOUNT THAT WILL GO ONTO THE PART.
That is why picking up the oil is a critical part and must be done with a loupe.
REASSEMBLE WHEEL TRAIN: The main wheel is place first. Then a medium amount of D-5 oil is placed at the barrel arbor. Wheel train is then re-assembled making sure the pivots clear the jewel holes.
Oiling the barrel arbor.
With wheel train and bridge put on I will lubricate the pivots on the wheel train.
MAIN WHEEL: medium amount of D-5...3rd wheel medium amount of 9020 oil...4th wheel light amount of 9010...Escape wheel light amount of 9010.
CLOSE-UP Oiling a Wheel Pivot.
Install Barrel Bridge and 3 screws also install click and click spring.
Lubricate Barrel Bridge with a heavy load of D-5.
Install crown wheel and screw. The crown wheel screw on ETA is a left hand thread. Clean with Rodico.
Install Ratchet Wheel and lubricate one or two teeth with a single medium drop of D-5.
FOR NOW we have finished the wheel train and barrel bridge. Now turn movement over and we will proceed to the bottom plate for motion works and keyless works.
REPLACE Canon Pinion.
NOTE: The canon pinion is steel and minute wheel is brass. The dissimilar metals allow the two wheels to run without lubrication.
Replace all keyless works components. As I install the keyless works I will place a little PML grease between the CLUTCH and WINDING PINION.
Canon Pin, minute wheel, and keyless works installed. The ETA keyless works is a real work of art.
Before installation of the stem we will lubricate with a little PML grease. Photo below shows where to lubricate stem.
Stem installed and cleaned with Rodico.
MOVEMENT TURNED OVER and the Pallet and Balance Assemblies will be installed.
Pallet Lever and Pallet installed.
Slightly blurred photo but you can see where the balance pivot will be placed. Also the impulse jewel must be aligned with the pallet lever fork. THIS TAKES A LITTLE PRACTICE.
With balance in place balance bridge screw is properly secured.
COMPLETED LUBRICATION AND ASSEMBLY OF THE ETA 2801-2.
