Smile replace 746 dial label

Hi

I'm wondering if anyone can help? I'm wanting to change the dial label on a 746 I've recently acquired. I can't seem to find any instructions as to how to do this. Can anyone give me some pointers? As detailed and non-techy as possible, as I'm new to this.

Thanks
K

I am not clear whether your problem is in removing the dial cover to change the label or sourcing a replacement label.

If the former, it is just a matter of prising off the central plastic disc. If the latter, the attached image may be of help.

I find the best way (especially for those stubborn jobbies) is to use a little plastic suction cup, of the sort used on the end of kids' bow-and-arrow sets. This facilitates easy removal without cracking the thin lip of plastic around the periphery of the central plastic disc.

The GPO way of removing the dial label cover was to use a rubber sucker, as these aren't readily available these days the cover can be easily removed by the use of a piece of sellotape; fold the tape over, place the sticky side on to the plastic label cover and with a little gentle persuasion the cover should "pop" off.

DO NOT BE TEMPTED to try and prise the cover off using a screwdriver you are almost certain to either break the cover or dial ring or possibly cause damage to the dial itself!!

Some of them can be removed by inserting an instrument screwdriver under the dial, between the dial and the phone body, and turning it. A shaped insert forces up the central disc if you get the position right,

Point taken! I usually use my fingernails, but have found a thin blade OK as long as one avoids a twisting motion - and proceeds GENTLY. I haven't broken one yet.

The above instruction is only valid for the earlier 706 type dials which are usually coloured the same as the main body of the telephone. For later plastic dials (746 or a 706s' that have been through BTs "Wipe up" process) proceed as detailed earlier in this post.

When I was an apprentice, the way we was shown how to remove the dial cover was to tap the dial with a number 2 screwdriver handle (about the number 3 hole) and the centre would pop out. I have seen the suction things but never used them.

That's jogged my memory. I remember that's how GPO engineers used to do it - a tap with a screwdriver handle, and the centre would just pop out. No doubt they'd had plenty of practice though, and knew exactly where and how hard to hit it.

On balance it's probably safer to use one of the other methods.

Tape is the best way to go, strong multi strand packing tape is best cause its really sticky. I used to use the tap with a No 1 or 2 screwdriver handle method put it takes practice. So be aware if you use any other method apart from stick tape you are very likely to crack the plastic cover :-(

The later ones had a hole for a pin you could push in.

In the early 1980's I was nosing through BT Yarnfield stores and they had racks of rubber stamps on dexion shelves with the names of the exchanges on them...and handfuls of the rubber suckers, mounted on small wooden dowels.

Sounds like the rubber suckers on the dowls were for hand grinding cylider head valve faces?

I definately used the rubber sucker when on "Sub's Apps" to replace dial labels. It was just a sucker (plastic type material) with a small ball shape to hold the sucker.
