How to adjust mileage on dials?

Hi,

A while ago I carelessly managed to break the needle on my dial which includes the mileage gauge. I have found a replacement instrument cluster on the internet but the replacement one has less miles on it than my current 944. I would therefore want to increase the miles on the new gauge. Does anybody know how easy it is to do? Somebody said you can just use a drill but is it THAT easy?

Cheers.

As long as you are increasing the mileage then a drill will work, decreasing (clocking) will break it. Be prepared for a long job. Easiest way is keep the old odometer and record the mileage on the new one (picture of the two odometers with a newspaper showing the date) so if you do sell it in the future you can prove mileages.

If you do use a a drill you'll finally see the needle hit the max speed![:)]

Cheers,
 
I had to do the same with mine, I just uesd a battery drill with an old round nail, filed square on one end the head cut off the other, it is slow as Fred says but it does work.

Also, make sure it it going the right way, finger speed reverse is ok, drill speed backwards will damage it!

Cheers Fred/mike . The replacement one apparently has the numbers 'out of line' as if it has been tampered with. Is this something which I can put right or should i avoid it?

Im struggling to find a replacement one for a decent price.
 
Is it oval dash or an early one?

I have an early car and that speedo you can take apart and rebuild. It is not easy but can be done, if they are well out of line.

I have no idea about the oval dash cars.

Where are you - I have a - now - working spare early speedo

What does having a newspaper prove? I have a stack of old newspapers in the shed so I could include one of those to imply I had swapped the speedo two years ago and have done very little mileage since.

Am I missing something? [8D]

Unfortunately I have an oval dash model [:mad:]. Cheers for the offer like.
 
Yes a stack of old newspapers that have yellowed with age due to the depletion of nascent oxygen, or is it the other way around. Anyway, the colour of the newspaper being nice and white in a picture would be good provenance. It's all based on trust any way. There is noting to stop you doctoring the replacement head or indeed disconnnecting the speedo drive. Never take the odomenter reading in blind faith. Use it in conjuction with the other signs.
 
Porshapart offer to set the odo to the correct mileage whenever you buy a S/H one from them. It might be worth buying one from them if you are not happy to do your own

Yes - it's dead easy to do.

Install the new gauge and then drive the car. You'll find that if you need another 20,000 miles on the new gauge then driving the car precisely 20,000 miles will do this. (You get the added bonus that those miles will be spent driving a 944, so they will be enjoyable ones!)

I just had a butchers at their website and it looks like they only sell locking wheel nuts and relay thingies for the 944! Is it worth me calling them?
 
Simon Butterworth used to sell bits out of his garage and he now trades as Porschapart in Ramsbottom in Lancashire.
 
Simon Davidson runs SAR Classics www.sarclassics.com which used to be known as www.essentialstyling.com

I've just noticed they now have links to all the pictures of Peter E's fantastic restoration on there [8D]
