G80 Speedo Gearbox
Posted: Mon Jul 09, 2018 3:57 pm
My speedo gearbox failed today - fell apart. I've had some problems with it before. The stepped chrome spacer outside the gearbox (021591) appears to have wear and burrs on both ends. I've tried uploading a photo but without success. Anyway it now measures about 0.825" in length and I'm fairly sure it's shorter than it used to be! Possibly not helping is that the cutouts in the adjusting ring are misshapen - not the nice square shape they should be.
I will need a new speedo gearbox. Can anyone please tell me:
- if the Indian made speedo gearboxes on Ebay work OK? They are closer to £10 instead of the 'proper' ones at more like £45.
- if my stepped spacer is best replaced - I'm not sure what the correct length of it should be or if that is critical. I could just file off the burrs.
- if it's worth me getting an engineer to sharpen up the square cutouts in the adjusting ring or maybe even cut two new ones at 90 degrees to the existing ones.
Cheers. Bruce.
