Default '73 clock stem removal

The clock in my '73 actually works. The stem has broken off with the setting **** and only a portion of the stem is sticking out now with no threads.

I can buy a clock stem and I have a new ****. Before I break something trying to remove the stem does anyone know how to remove the stem? Can it be removed with the clock in the car?

Thanks.

Not easily. You have to take the clock out of the cluster in order to install the new stem. You might be able to reach the back of the cluster to access the clock, but there isn't much wiggle room back there.

I put a stem in my '68. It's not rocket science.

Be careful, the clocks are junk, it may be better to have a clock that does not work, than a break in the line to the oil pressure guage

after you reinstall the clock in the bezel and you think everything is right, start the engine, oil starts leaking on the left passenger floor.

I'm reviving this old thread because I have the same issue - a clock with a broken set stem.

I have 2 clocks, one with a good set stem, and unrepairable clock - and another with a broken set stem, and a working clock.

I'm not a rocket scientist, but I still don't know how to replace the stem! How is a set stem removed? It looks like the gear on the end of the stem needs to be removed, but not sure how to remove it.

Thanks,
Matt

You need to remove the clock mechanism from the case. This means, pulling the hands and the bezel. The bezel is held to the case by three aluminum tabs. These tabs were never designed to be bent more than once so be very careful that you don't bend then back too far. Once you have the bezel off, you will need bend back to steel tabs and another crimp along the edge of the case. The mechanism will then be free to pull from the case. The gear is pressed on the stem. You use a very fine punch to push the stem out of the gear. Be very careful when you push it out that you don't lose the spring between the gear and the support plate. The gear is then pressed on the new stem.

The replacement stem I ordered (from ZIP if memeory serves, but it's been a while) came with installation instructions and a diagram.

That's why I'm having the problem - no instructions. I just have 2 clocks, and am trying to move the good stem on the bad clock to replace the bad stem on the good clock.

Thanks! I have the two clocks disassembled, I just couldn't tell how the gear was attached to the stem, but what you said makes perfect sense.
