Hello, does anyone know of a source of speedometer internal components?
I'm looking for a small white plastic gear which is located inside the speedo. There are 2 gears inside which are worm-driven, and one of them has cracked, which I'm pretty sure is the cause of my annoying needle flicker.
I'd be interested to know if anyone else has had the same problem?
I discovered the cracked gear during my investigation into the needle flicker. First I checked the speedo cable, which was in good condition. Then I rotated the speedo drive directly into the speedo with an electric drill, and this gave a steady needle. That stumped me at first because there was no obvious cause, but then I rotated the drive with a small screwdriver and noticed it was stiff to turn roughly every 20 rotations. So then I took the speedo apart to try to find what was causing the stiffness and eventually spotted a slight crack in one of the gears which must be increasing the gear tooth pitch and therefore causing the worm drive to jam slightly every time the crack passed it.
Anyway, so that's why I'm looking for a replacement gear!!
Any suggestions of a source of replacement gears will be much appreciated.
Alternatively does anyone have a speedo for sale?. Working or not working (I just need the gear out of it).
