[Hammarlund] Clock Repair

[Rodger Singley]

The first time I saw this method described was in the “Mac’s Service Shop” column written by John Frye in the old Radio and Television News magazine.  One important part he noted was be prepared to drop additional oil around the shaft or other access point in use as the clock cools because it will suck in a considerable amount of air and adding this additional oil will reduce the amount of heat/cool cycles you need to use to add sufficient oil.  I have used the method several times on various clock movements and it worked in all but one case; the one that didn’t work had a severely worn movement when I dissected it and the lesson from that is to lubricate the movements before it tries to run a long time without proper lubrication.

The 100W method worked very well for me on the Telechron clock in my HQ100.
The movement was very noisy and erratic. Now I can hardly hear it. I used
Mobil synthetic oil (0W20). There is a video on Youtube showing how to do
it. Next is the rotor of my HQ180A clock.
