Please help to identify urgos movement model???

[NEW65]

Hi everyone,

I have a very large corner grandfather clock made by interclock - it has an urgos movement fitted. Without removing the movement i am finding it difficult to identify the model number of the movement. I have tried to use a mirror but its still proving difficult to identify the letters/numbers on the back plate of the movement! I have done my best but wonder if anyone can help me out here to confirm whether i am correct?

I need a crank key for the movement - the old crank key was either 4mm or 4.5mm but i am not sure which one? Maybe to be safe i should purchase the 4.5mm crank key?

The code on the movement as i read it was: UW353563-01 Weights are on cables and it has westminster chimes only. ( i checked it out on Mark's website but nothing matched)

Any help would be very much appreciated - i am hoping that there is a link between the model of the movement and the size of the crank key?

Thank you as always.

Kind regards,

Simon

NEWO,

If it is a large movement, it is probably a UW03. It was made in many versions. It takes a #8 crank but be sure to get an Urgos crank. It has a deeper broached bore. A generic crank will work but it will be a little small and the square will not have as much purchase on the winding arbor as it should have.

Have you checked the bottom of the case thoroughly? Lots of keys/cranks hide out there.

All Urgos used the same crank. We have them.

Hi Mark, would that be 4.5mm for the urgos crank key? I was informed that this is the size but still unsure without taking dial off and measuring the size of the square with calipers! Thank you as always, Simon

It will be an Urgos crank. A little larger in overall size than most, and has the Urgos trademark at the center of the crank arm.

I don't have the mm size, but Willy is correct, it is #8. You could translate from a Timesavers catalogue. I don't have it handy.

#8 is 4.25mm, American made is 4.00mm

 

[matthiasi]

#8 is 4.25'', American made is 4.00"​

Now that would be a HUGE crank, more for a Tower Clock. Bet you the crank portion would be at least 3 ft long in this case....


I think you mean mm, not inches....

A #8 will work for Urgos, as others have already suggested

Hi, managed to get hold of a crank key for my urgos movement! I ordered a 4.25mm key. When it arrived i tried it and the inside of the key wasn't deep enough to get sufficient hold on the squares. So i drilled extra depth out of the key and tried it again. It reached perfectly! However it was still a little sloppy for my liking so reckon i should have ordered a 4mm square crank key (must have been USA size then?). Anyway although it worked okay i was still not that happy that it wasn't a snug fit so i slightly squashed it inwards using a vice (key made from really thick brass!) which was more difficult than i expected! Finally i managed to get it to fit much better on the squares of the movement though... makes me wonder which movement the crank key was made for as it nowhere near reached the start of the square on this Urgos movement??! Thanks for all your help guys, always appreciated Simon

Looks like i overlooked Willie's post which answers my query in full, cheers Bill for highlighting this

I'm glad you didn't take it as an insult! I was afraid you might. After I posted, I almost went back to edit to make it clear that I did not mean it that way.
Is there any chance that when you drilled it deeper, you opened up the square a little? And I'm not quite sure what "a little small" refers to. My first thought was that it would be tight on the arbor, but now I'm thinking he meant that the handle would be a little shorter. I'm a newbie, and haven't managed to touch anything like this yet.

You mention "Key". Did you buy a key or a crank? Not a good idea to use a key, especially if it has been flattened. You can wreck a good clock by doing stuff like this.

All you need is a plain ole Urgos CRANK ...

Hi Bill, thank you for your post. I was quite okay with your post and was pleased that you mentioned that Willie had already answered my question in full... i should have noticed it but just logged in and gave an update on my problems with the Crank key. I used a 3.5mm drill bit to take out more depth from the crank key and yes i had to be very very careful to not round the square on the inside of the key but all seemed okay? Reckon i had some luck along the way as i used an hand held electic drill to do this! Willie, yes it was a crank key... i could have used an ordinary key but thought better of it... thank you to everyone who has advised me on the thread... tc, Simon
