White House K10 - a story of regeneration

[Ninemeister_imp]

It's me again.

One of my less successful ideas was the replacement of the speedo face which unfortunately resulted in an erratic zero-point on the mechanism. I did think about attempting a fix on the servo motor in the speedo itself, however the eBay gods smiled down on me when I found this 2017 speedo listed for parts. The seller said that the display had failed but the two instruments worked, so I made my bid and am glad to say won it for £72 including carriage - less than I paid for the mph dial! Ho hum, you live and learn.

All I needed to do now was to strip out the clocks, pull my instrument cluster apart and change them over. I did this tonight, taking photos along the way as I figured there might be someone interested in what's inside and how the clocks are assembled.

The first three photos are of the eBay clocks.
Next photo is of my clock set which has the speedo zero at 40mph.

Two allen screws remove the chrome covers, three black self-tappers remove the back.

The mounting frame is removed by undoing the four M6 (10mm a/f) nuts.
Another black self tapper on the cable p-clip, lever out the soft plastic covers and the wiring loom can be unplugged from the main board.

The bezel & circuit boards are fixed to the (white) frame with 17 silver self-tapping screws - just remove them all. I did this with a power driver, however one note on that is not to use it to put the instruments back together with same as the screws can easily be over-tightened which would strip the fixing holes.
