Clock dis-assembly?

I need to change the lens on this clock and want to peak inside and have never taken one apart before. The nuts on the back just spin. Does the knurled knob on the clock time set dial come off the end of the adjusting shaft?
Any other recommendations would be greatly appreciated as well. Thanks

 

You have to hold the stem with a pair of Needle Nose Pliers while you turn the knob

 

Once you have the clock apart and can see the gears, spray them with electronic cleaner spray. Then oil the bushings or anything that is spinning on a shaft with clock oil. Use only clock oil or the works might get gummed up.

Test the clock by connecting it and letting it run overnight. Don't want to button everything up and find out it's not working.

 

Have you thought about switching to Quartz? Since you have it apart now's the time to do it!

 

I have. but still need to get the darn thing open.

I was able to get the from knurled knob off to change the lens. However, I would like to peak inside to see what's going on in there and/or replace the internals. The 3 nuts on the back just spin. Any suggestions to get those off? Thanks

 

I assume you tried a little penetrating fluid or similar? I had same issue on mine and ultimately didn't find a way so I'm watching this thread with interest to see if anyone else has a tip or secret to get to the hidden studs?! Some gorilla was working part time at the clock supplier back in the day?!?

 

Yep, tried a little penetrating oil.....I assume if you can get the front face number plate off the are phillip screw heads or a bolt head that you have to hold down and then the nuts will stop spinning... but the number plate is so nice i don't want to mess with it.. hoping someone has some advice....

 

Pull forward on the clock face with you fingers as you simultaneously unscrew the nuts. That may work...
