Click spring replacement


Pieter

Recommended Posts

How do you replace the right click spring in a Smith’s Enfield railway clock? How do you attach it to the front plate? With a rivet and a hammer or bolt? Not much room behind the plate for there is the clock spring. Any video link?

I drilled the rivet out. How does the screw get enough grip? The plate is very thin….

The click spring should have a tiny notch that fits into a small hole in the plate. Just a tight screw down will be fine or to be safe a spring washer. (If room)

Hi Pieter, I have purchased these rivets from a company called Accu - heres a link https://www.accu.co.uk/ the rivet I used  is 2mm x 6mm Button Head Solid Rivets (DIN 660) - Stainless Steel (A2)

You can buy the springs from lots of sellers online but I have found some sizes are very hard to come by. They are either Left or Right and the critical thing is the distance between the screw hole and the tag that engages with the hole in the plate. I ended up buying a straight spring and bending it to the required size.  I bought mine from this seller on eBay

eBay - Advanced Search - Shops - Find Shops - Lisa's Pet and Home Store

I can understand why you would prefer to use a rivet but to be honest I found it impossible to splay the rivet enough without breaking the spring, so I gave up and used a self tapping screw which has worked really well.

Good luck !

Thank you for the advise. The frontplate is so thin so i am wondering if a self tapping screw will hold but i will give it a try. Do you know by the way hiw to adjust the hour hand on the fusee clock? Is is a little bit off so i like to adjust it.

Normally the hour hand on a fusee clock is friction tight. When you have the minute hand pinned on hold the minute hand near the center then try to move the hour hand by holding it as near to the center and move it to the place you need it to be. Always move hands from the center this prevents bending the hand and breaking off.

    • As I'm only cleaning watches in small numbers at home, I pre-clean any significant deposits of old grease and oil before using the cleaning solutions. I scrape off deposits with pegwood and Rodico, and if really dirty, wash parts in naphtha with a brush.  So I'm happy using DX, but can understand why it's avoided by the pros.
    • I think attaching a nut to the lid to pull it off is the least destructive, any damage damage on the outside is going to an easier fix than any created when trying to push it out from the inside. Scratching up the inside of the lid , mainspring or arbor bearing will be risk. Just my opinion.
    • yes the things we read in the universe I did see some where it was either difficult to clean off or it contaminated the cleaning fluid there was some issue with cleaning. I was trying to remember something about grease where as opposed to a substance of a specific consistency they were suggesting it had a base oil with something to thicken it. That conceivably could indicate that the two could separate and that would be an issue. But there is something else going on here that I had remembered so I have a link below and the description of the 9501 notice the word that I highlighted? Notice that word appears quite a bit on this particular page like 9415 has that property all so they 8200 mainspring grease and that definitely has to be mixed up when you go to use it because it definitely separates. just in case you didn't remember that nifty word there is a Wikipedia entry. https://en.wikipedia.org/wiki/Thixotropy   https://www.moebius-lubricants.ch/en/products/greases I wonder if what you're seeing is the boron nitride left behind after cleaning. In other words it's the high-pressure part of the grease and it's probably embedding itself into the metal which is why it doesn't clean off and shouldn't be a problem?
    • Yes and no. I use Moebius 9501 synthetic grease and it is significantly runnier than the Moebius 9504 synthetic grease (and I assume Molykote DX) that I previously used. I haven't seen 9504 spread and it is in my opinion the best grease money can buy. However, my current method of cleaning doesn't remove it from the parts, so that's why I have decided to use the 9501 instead. I believe I read somewhere that Molykote DX too is difficult to clean off. Thinking about it, I'm pretty sure my 9501 grease which expired in June 2022 is runnier now than it was when it was new, but whether new or old it always needs to be stirred before use. So, that's why I treat the parts of the keyless works, cannon pinion, etc. with epilame. That was very thoughtful of you and something that had completely passed me by. Not sure what the epilame will do when it wears off in a non-oiled hole. Anyone?
    • Hi not found one either yet,  close relative is the 436 and 4361 according to ranff.db.   It gives quire a lot of detail but not as good as the old site.      RANFF.DB.
