With all the parts cleaned, and they were dirty!


 It is time to check out some of the parts before assembly, as the movement has no movement in the train wheels, etc when it was being deconstructed.


First I take out the bad dents in the dust Ring then take out the Dents in Main Plate.


Next, I demagnetise the Setting lever with my line free machine.


Then I replace the Balance Wheel minus its hairspring to check the pivots correctly, and the play in the wheel confirmed the top pivot is broken. Strip off Balance cock and Wheel.


Now to replace the Winding and Keyless Work and check it operates correctly, which it does, but note to self, when you tighten the screw on the Keyless Work make sure that you cannot see the Setting screw head. If the head can be seen the large washer will clamp down on the Keyless Work and stop it working correctly.


Next, refit all the train wheels and make sure they run freely, as they were jammed when stripping down movement. Now after a good clean and oiling, they are running fine.

Now due to the Barrel Arbor only slipping into the Barrel as the Mainspring is attached to the Barrel lid, it is easy to slide the Barrel under the Centre Wheel and then slide back in the Arbor. Refit the Barrel Bridge and check the winding and setting work. Watch the sliding Pinion from the dial side, slide in and out freely, also due to no Pallet fork fitted the train wheels also run freely.


Replacing the Pallet fork and bridge is the last item and can do on this movement until I get or make a replacement Balance shaft.
