Thanks, Matt. I'm going to find mine this evening and see if I'm seeing the same thing you are. I purchased an OEM set (tach also), and after reading Keith's comment, I'm hoping the clock is the quartz version. I recall some slight discoloration near the clock adjustment knob that I'll need to address providing the clock actually functions.

Hey Keith,

Or anyone who has torn apart one of these clocks.

Does the adjustment knob have to come off, first, before the bezel and lens can be removed? if so, how does the knob come off?

Thanks

Well, gentlemen, I'm still looking for a OEM clock for my Ol' Girl, damnit.

Once i figured out the adjustment knob just pulls off, I sharpened the tip of a paint can opener, and got busy with the tedious chore of lifting the crimp on the back of the bezel.

You have to get the crimp nearly vertical before the bezel will separate from the housing. Once is does, the bezel, inside trim plate, lens, paper gasket, rubber o-ring, and the housing will all separate.

It doesn't pull off, you have to unscrew it as the end of the adjustment rod is threaded with something like 4-40 threads.

To remove the guts from the housing, you need to straighten 3 tabs that protrude thru the housing.

Unfortunately, that's where this How-To ends.

The inner mechanism is built on a plastic frame, like the frame of a 3-story building. The upper floor of the frame holds the spade connectors and their rubber boot.

Apparently, whoever removed this clock got too aggressive while pulling on the wires, and broke that upper floor. It crumbled out in pieces. Then, as I was trying to free the gears, so that the hands would move, one of the tiny gears broke away from the frame. That's when the whole mess got tossed into the trash. Bummer.

OK, I see that now, thanks for clarifying. I guess my old eyes are too far gone to be a clock builder.

What a complete drag, Matt. I'm disappointed for you. However, don't toss it in the trash just yet! You've inspired me to get mine out and start the same process. Given my clumsiness, I'll likely break something and have need of a replacement part. Who knows, you might be able to recoup a few bucks from me, or others, as they go through the process-

Hoover,

OK, I'll save everything for now. Just PM me your address, and I'll send you everything, if you need it.

I have a clock from a 78 and the shaft was splined, no threads. So you would just pull it off. But just like yours all the plastic was in pieces. Fortunately mine came with the tach you have for basically nothing, a throw in.
Sorry to hear about yours

Ernie,

Thanks. You are correct, the adjustment rod is splined not threaded. I had to break out the magnifying glass to see it. It's rare for Keith to be mistaken.

BTW, the tach I got from you continues to work perfectly. Thank you very much!!

Matt

Before you do....call isi and talk to a tech. They had the replacement quartz movement, the adjusting knobs and the lenses...not cheap but mine looks brand new and is accurate to the second. https://www.clocksandgauges.com/

I bought the quartz movement off their ebay store for about 80 bucks and polished my lens and used fluorescent orange model enamel paint for the hands. I also used a led bulb from superbrightleds

Scotty,

If you don't mind my asking, what did they charge you to rebuild your clock?
