VDO Series 1 Speedometer Help..

[plasticblack]

I have a VDO series 1 Speedo with a broken glass.

Does anyone know how to remove the Chrome Bezel and dismantle the clock please.

I'm not seeing a simple solution right now and forcing the chrome ring looks like it will break/snap without much pressure?

I've taken apart and re assembled stock VDO speedos before. You have to pry around the back of the chrome ring to remove it with a tool like a spudger for opening laptops, etc. There are business that specialize in fixing and recalibrating speedos, etc., for trucks so that would another option.

Speedy Cables (http://www.speedycables.com/) have rebuilt/ modified etc gauges for me in the past.

Bit of a long turn around time, about 4-5 week i seem to remember, but they did a great job.

Practice on a stock speedo first. You will see that it's not difficult to take one apart. Has anyone used a shop to re calibrate their speedo to different sized tires?

Is there a "Special tool" to refit the bezels... I mean to bend the edge over again correctly 

I am working on one of my VDO Jet cockpit gauges/clock at the moment

I worked for VDO locally for a while.
A small flat blade screwdriver with blunted off edges is what I use to remover the bezel. Work slowly around and gently pry the edge off the case.
We always used the round blunt handle end of a screwdriver to roll around the bezel when re-fitting.
If you feel the need to clean while it's apart, then do so gently with a soft lint-free cloth........gently.

Calibrating a mechanical speedo involves checking the "count" over a set distance, putting the speedo on a calibrated drive using the count recorded, then adjusting the mechanical spring tension of the meter windings until they are accurate. Inconsistencies high to low deflection can be adjusted by "tweaking" the magnetic cup that surrounds the windings.
So there you go!

Now that's what I was looking for.

Great Information Thanks.
