Hello everyone. I picked this beauty for $20 but its missing the bottom block. This is my first 400 day clock I've worked on so I'm trying to figure out whats needed. My first question is how to identify the plate number I've read about on other forums here. I've added photos. Theres no plate number. Second I see on timesavers that there's several bottom blocks for a kundo but the height and width are all different theres no mention on the thickness. Is the thickness of them all the same? Thank you in advance for all of your help. I've been stumped these past few days.

You generally need the Repair Guide written by Terwilliger to identify the plate/clock. The guide suggests that it is plate 1375 and takes a 0.0032" suspension spring if needed. As for blocks, they're not all the same width/dimensions, plus some have a taper pin in them and some don't. You haven't shown us the pendulum. Dollars to donuts, the lower block is captive in the suspension lock mechanism that Kundo was famous for. If you see a thin spring around the top part of the pendulum along with a cap that slides up and down, the block is probably inside. Trick is that the factory put a pin through the bottom block that is an interference fit. It doesn't slip out easily...it has to be carefully driven out. Usually when I get the pin out, which then releases the block, I carefully use a small file and knock down the knurling on the pin so that it will slide in/out easily. Kundo did this to keep the pin from coming out during shipment, releasing the pendulum to careen around and break things.

On second thought, after looking at the lower part of the suspension guard, you might have a more standard pendulum without the issues I mentioned above. So, again, show us the pendulum.

Thanks. My first hypothesis was wrong...so you just need a new bottom block with a taper pin installed. You could measure the width between the hook with a digital caliper to find out what you need. You're probably going to need a new suspension spring because the long-gone block broke off the lower 5-6mm of the spring and just reattaching to what's left might not work. Best to get a package of three (0.0032" it appears) and go from there.

I have measured between the hooks and I came .085 or 2.159mm but I'm having a hard time finding a bottom block with that thickness. I called timesavers and they told me they didn't know the thickness just the height and width. Also I dont know what height and width is that I'll need. How can I find that out?

Call Horolovar. I didn't get much help from Timesavers either, Horolovar was better. Try this:

Believe this clock would have had a different lower block than the typical rectangular one to use with that sliding pendulum lock.
Finding one may be difficult and honestly that early pendulum lock is not the best so to get it running a rectangular one will do.
Attached a pic of how the lower block would have looked.

The guide suggests four different suspension units. Two of them have the lower block you show. The other two are the standard square block. I try and just find something that works!!

Does the guide tell the height and width of the standard square blocks you mentioned?

Wayne is correct. This is the bottom block used with the ring bottom suspension guard, Unit 3A, .0032".

Any idea where I can find that bottom block?
I don't think anyone sells them. The example I've shown one is from one of my clocks awaiting work.

This one will work for you, or a similar part from Timesavers:

Only blocks I've seen are the rectangle ones, have to watch the thickness otherwise there almost universal. Picked up some from the bay in a 5 pack but for minature clocks there a little thick but there was enough meat to file them down to fit.

So i know it took me awhile but I did get it up and running. I had to order the repair guide. I'm attaching some pictures of my first 400 day clock I've repair. Thank you everyone for your help and advice. 20210711_183243.jpg 20210711_183257.jpg

Glad you persisted and were able to get the clock running! What's next? ;)

Maybe you can come down here and figure out why my similar period Kundo doesn't run well at all! :?|

I have one that doesn't run well either. Ran like a snail for a couple weeks, then just stopped. Patrick is addicted now, all it takes is one.
