Speedo change from KPH to MPH

[icarus001]

My import has a KPH speedo, I was going to buy some decals off here to change it to mph, but when I popped the speedo out of the housing it appears to be a sealed unit, I can't get into it unless I damage the metal seal around the front of it.

Is this right? Or is there a knack to popping it off.

Hi,

Yes you need to work your way round it opening up the rim.

Think the mph decals are slightly different. Either the gaps for the miles or the screw holes are in a different place or the start point.

You can get conversion decals for the km to miles conversion, don't know if norbo does them but have seen them on ebay.

Biggest problems are getting the brittle needles off without breaking and if you only do the speedo it looks a different finish to the tacho so you have to do both.

I have found that the XS model speedo fits inside the housing so you can buy one and simply swap the guts over. Only visual difference is that the xs has the white mph and yellow kmh.

Few from the states on ebay, way cheaper than finding a 4LO mph one.

They do fit in the lc cases complete but do not have the 2 little locating tabs on the case. Look the same with the covers on.

If you change the face, mark the resting place for the needle or you will loose the calibration , also be careful how you prise the needle off,
It can be done, i just bought a kph speedo and fitted my mph face, all fine on the speedo, odometer is still kms,

I have just done this with mine. I had the backs off twice and bought a converter that fits to the speedo cable. Unfortunately I broke the needle just as I had got everything sorted and trying to get one is like rocking horse poo. In the end I bought a mph clock from a very nice gent on here!!! You can get decals and the spacing is the same.
