[1984mini25]

The Speedo in the 25 has died, the 120mph 3clock set up also fitted to the clubby GT and 1100 special, and there fore needs replacing. I luckily have a spare 120 mph 3-clock set up with known working Speedo, but the mileage on that one is 30k more than what mine is.

So how would one change the mileage on the smiths 2/3 clock Speedos?

[wolfys_mini]

wind it forward until you get to what you want.

i did find an easier way, but i cant for the life of me remember how

[ginigwunkle]

put the spoode cable on the speedo out of the car, fasten the drill on the other end and whizz away til you get where you wants......

simple!! lol

[hystrix cristata]

don't need to just keep the old clocks and write down the millage when you changed it. take a picture with a date on if you were really that bothered.or you could take the front of the clock off and sit there spinning it round till you get the correct millage

I tried that, that’s how I know the spare set work, but my drill only tops out at 20mph, and my current original mileage is genuine 55k, were as the replacement set is 85k so might be there for some time.

I will do for know, and keep a note of my mileage, but I would prefer it to be corrected, as it will go with all the service history, mot’s etc.

LOL I did this too, I mustered up about 9 miles before I couldn't be bothered and just gave up!

[1340 gt]

i did mine too when i fitted a mgb speedo and new engine. it took ages to get a few miles in the wrong direction (quicker to go right round in my case!)

so i took mine apart and completely re set it to zero. it works beautifully but is very fiddly and i dont really reccomend it. i certainly dont advise or think any one should be "clocking" their cars to make the miles seem less.

my clubman is far from standard and came with no clocks, any potential buyer will be told the mileage shown is from restoration only and true milage could be anyhting.

[dklawson]

It can be done as 1340gt said by manipulating the odo wheels. However, in the U.S. (and I'm sure also in the U.K.) this is considered "illegal". There are ways to do this legally but like everything legal it comes at a price. You could contact Speedy Cables and ask them about it. In the U.S. it is legal for speedometer shops to reset an odometer to a predetermined mileage when the owner submits an affidavit swearing to the accuracy of the desired change AND signs a release waiver to protect the speedometer shop. This gives you a written record stating what the odometer has been reset to and presumably... why. Again, it gets you what you want and protects you against any liability when you go to sell the car, The drawback is that it isn't free.

If you go with the electric drill method you're going to need a high-speed electric drill operating in reverse for a LONG time. Consider that one of the most common speedo configuration operates at 1280 turns/mile. If you have a drill motor running at 1280 RPM, the odometer will roll over a mile a minute. It sounds like you need to move forward 70,000 miles to subtract 30k miles off the odometer. At 1280 RPM that's roughly... 48 to 49 days non-stop.

[robson]

rotary tool kit? i think mines 12k RPM, some air grinders go up to 22k which could easily be hooked up

[pantera2075]

It's not illegal in the uk to change the milage on the clocks. It is illegal to mis-represent that milage - for instance when selling the car. You are covered if you say something like "I cannot guarantee the milage" when selling.

To change the reading, get a tiny watchmakers screwdriver. On the top rear of the milometer wheels you will see some small brass forks that slot between the wheels. Lift these up individually with the screwdriver and spin the wheels with your finger. If it was me i'd just do the 8 back to a 5 and leave the rest alone. Note, this works on the earlier centre speedo, i'm not completely sure on later clocks.

How about these guys?

a little radio control car (like the minis from marks and Spencer's) is good for turning the clock and to save you going forwards, a pair of tweezers holding the ratchet closed allows you to go backwards.

not that Ive ever done it of course
