One of the few things that rattles in the Chim is the glass in the speedo, it is a real niggle, as the glass (plastic) on the front of the speedometer has been put on, in the wrong order, before the black plastic spacer, so there is no clamping force on the glass, and the glass also rests on the needle casing erratic movement sometimes.

I have the speedo out, and would like to reassemble it in the correct order. I assume I need to get the black plastic moulding on the backside off, but seems to be stuck on. Not sure If I just need to use some brute force and prise it off, or is there a special trick or tool required. Don't want to break anything if possible.

Anyone experience of this?

The black plastic cap covering the rear of the speedometer doesn't want to budge, and looks like the aluminium trim around the front bezel is crimped in place - making this a sealed unit it seems. i.e. no way of extracting the actual clock face and assembly its self.

If this is the case and there is no way in from the back, then looks like I will have to see if the manufacturer and remedy anything.

Has nobody ever had one of these apart? (Is a Caerbont unit)

The only ones I've heard of people dismantling are the ETB ones to 'fix' the missing odometer click (which most of us kind of like anyway ~ its just a heartbeat..). CAI are all Smiths / CAI / Greengauges / speedy cables group, don't think it costs much to have them fix it, but various reports of time taken depends on their current workload I guess.

Just spoken to Caerbont who confirmed it is a sealed unit. The bezel is pressed on, and hence cannot be DIY disassembled.

They will reassemble it in the correct order if I post it to them.

well I just got into my early ETB unit pretty easily after the factory didn't bother responding to my enquiry about an overhaul/battery replacement. I went in via the bezel. To start the prising off i made a horizontal cut into the crimped on section's back (ie on the reverse of the lip) with a hacksaw blade, at the bottom. his gave me a very thin bit to work at. Once i had prised up one bit it was just a matter of working carefully round about 2/3 of the rim and I could pop it off. Once I had replaced my battery i just carefully pushed the bezel lip back on. Once on the car you wont be able to se a thing.... Obviously a repaint of the bezel was needed as bending up the lip caused cracking in the paint. Twas easy once i got in to the lip....
