Speedometer Needle Calibration

[Black Magic]

Hi all,

I know Ive asked about this before but does anyone know how to calibrate the needle on the speedometer?

You can remove the instrument binnacle and reposition the needle (use a fork to lever it off and push back on again).

Note: if you're not careful, you can mess up the spindle at the rear of the speedo, remove needle with care. If the speedo isn't out by much, I'd be inclined to leave it alone. If you're running a non-factory rolling radius on aftermarket rims, this can throw off the speedo.

Agreed.Ok the FTO has a digital odometer, so I guess all you'd need to clock it is a laptop? But with old skool analog dials, (where people would actaully wind back the clock), getting it wrong could result in a jumpy needle action. Tell tale sign of a clocked car.
Mess up the needle movement and try explaining that one come resale time. Actually while you're at it, ask how it has come out of calibration in the first place?

Its a weird one, tried figuring this out in previous post, "dial problems"..

Reckon a conversion cable was put in, coz odometer is reading in miles.
The speed clock is in both miles & klms, plotted against a satnav, and its reading consistently 4/5ths of its correct speed, ie car reads 50km, but its actually doing 40kms, car reads 100kms, actually doin 80kms, car 150km, actual 120km.

Took out the dials & had a look at the needle, but this is before you told me exactly how to take it off (CJ)

I reckon you are right though, I'll just leave it alone
