ok, i am trying a few different things with a spare set of speedo clocks i have, and i thought i would post it here in case it is any help to anyone smile.gif

Removal from car
locate and undo the two allen key bolts that are in the speedo surround at approx 10 and 2 o'clock using a 3mm allen key
Attached File  DSC_0132.JPG ( 320.01k ) Number of downloads: 197


then pull out the surround. it is only held in with some spring clips, but be careful not to break it. you will then see four more allen key bolts. two at the top, two at the bottom all 3mm allen key again. once these are out, you can pull the whole unit forward.

Attached File  DSC_0135.JPG ( 299.26k ) Number of downloads: 111
Attached File  DSC_0136.JPG ( 318.54k ) Number of downloads: 122


once you pull the clocks out far enough, you will see a plug on each side. remove these and then completely remove the whole unit.
Attached File  DSC_0137.JPG ( 293.89k ) Number of downloads: 120
Attached File  DSC_0138.JPG ( 352.85k ) Number of downloads: 115


phase 1 clocks first
first off, remove the white cover off the back of the unit by prising up the clips around the edge and removing the two long phillips screws from it.
Attached File  DSC_0127.JPG ( 1.97mb ) Number of downloads: 147
Attached File  DSC_0128.JPG ( 1.78mb ) Number of downloads: 133


next there are 6 more black phillips screws in the circuit board behind the white cover. remove these.
Attached File  DSC_0129.JPG ( 417.41k ) Number of downloads: 120


next, undo the main white section of the speedo assembly from the black and perspex front part by prising back the clips around the edges.
Attached File  DSC_0127.JPG ( 1.97mb ) Number of downloads: 147


you will be left with this:
Attached File  DSC_0125.JPG ( 439.02k ) Number of downloads: 205


on the back of the board, you will notice three groups of four pins, looking like this:
Attached File  DSC_0131.JPG ( 451.09k ) Number of downloads: 139


you should be able to gently push these forward to remove each 'clock' from the circuit board, leaving you with something like this:
Attached File  DSC_0123.JPG ( 397.29k ) Number of downloads: 155


it should then be a simple case of removing the circuit board from the white plastic housing. don't forget to note which way round the warning light graphic strip goes!
Attached File  DSC_0126.JPG ( 324.07k ) Number of downloads: 151


on the board is the odometer assembly. if you are changing your display lighting to blue, you will want to remove the green strip behind it or you get a sort of aquamarine colour laugh.gif
Attached File  DSC_0119.JPG ( 404.46k ) Number of downloads: 129


you don't have to remove the odo, but i found it easier, plus it means i know how to remove it if i need to smile.gif to remove it, you need to gently prise up the plastic bar that locks in the ribbon cable
Attached File  DSC_0112.JPG ( 285.42k ) Number of downloads: 127


the ribbon will then pull out, leaving you with this:
Attached File  DSC_0116.JPG ( 367.21k ) Number of downloads: 105
Attached File  DSC_0117.JPG ( 308.41k ) Number of downloads: 104


remove the black front cover by prising off the clips around the outside. you will now have this:
Attached File  DSC_0113.JPG ( 321.82k ) Number of downloads: 118


GENTLY prise out the glass screen, and this is what you will see:
Attached File  DSC_0114.JPG ( 396.44k ) Number of downloads: 110


remove the green bit.........
Attached File  DSC_0115.JPG ( 275.52k ) Number of downloads: 103


get some decent tracing paper and make a new green bit out of tracing paper so it is white instead of green and put where the green thing was. this has to be done otherwise the odo is unreadable

and then reassemble it. job done.

now, as for the clocks, the green stuff is embedded in the face itself, and will not come off sad.gif
Attached File  DSC_0122.JPG ( 380.89k ) Number of downloads: 125


you can peel the face off, i did it, but you still can't get to the green stuff sad.gif so i am going to try some different combinations of lighting behind them and post results on here as i get them thumbup.gif


ok, phase 2 clocks now.

the procedure is pretty much the same, but, not as easy sad.gif

firstly, remove the black rear cover as above for the phase 1, but it isn't white wink.gif
Attached File  DSC_0139.JPG ( 398.96k ) Number of downloads: 121


you will see a very similar picture to the phase 1 setup. as before, remove the six screws, and then pop the clock pins through the circuit board to release it.
Attached File  DSC_0140.JPG ( 549.15k ) Number of downloads: 117


now you will spot the difference, the odo is hard wired to the circuit board to prevent it being removed easily. if you are brave like i was this morning, you can desolder the two groups of 4 pins, and gently lever up the screen to enable the green plastic to be removed and replaced with tracing paper. if not, it will have to stay turquoise sad.gif BE WARNED! THIS IS FIDDLY AS HELL AND YOU MIGHT GET VERY VERY FRUSTRATED WITH IT IF YOU DO ATTEMPT IT rant.gif laugh.gif
Attached File  DSC_0141.JPG ( 287.82k ) Number of downloads: 105
Attached File  DSC_0142.JPG ( 485.59k ) Number of downloads: 106


and the finished article
Attached File  DSC_0145.JPG ( 298.88k ) Number of downloads: 117


as you can see, i have a couple of segments out. i think i have a dry joint when i resoldered it, so i will have to do that another day.

hope it helps thumbup.gif

i have ordered some strips, 2 at the moment, and i will have a go with them. if i get it all right, i might do this other speedo and sell it on smile.gif
i have also ordered some led replacement 286 bulb units and i'm going to see how they compare.. then all i need is a blue illuminated cigarette lighter, and some serious soldering work to sort out all the window switches etc to blue laugh.gif
