|
|
I have fitted a black face speedo and finally have the fuel gauge working accurately by fitting and adjusting the new tank sender. However I feel the speedo is about 10klm/hr. out at 90klm/hr.( dual reading speedo) this of course is due to the 3.9 diff and Sprite gearbox.
So where in Sydney can I get it recalibrated.

I believe Premier Instruments in Canberra may be able to help. Their phone no. is 0412 484 385.

If it's reading high, I'd regard it as a licence saver. I don't know about there, but here, you will get fined and lose points if the speed camera says you're only 1km/hr over the limit so regardless of driving habits, anything that keeps you safe is welcome in my world.

Try this mob in Penrith called Attspeed specializing in vintage stuff
Ph 02 9833 0055
I am in the spot as you, how do you find the 3.9 diff behind the 1098 compared to going the five speed.

thanks I have contacted them and just received a reply. I think I did not present my problem right.
Travelling to my sons wedding the two way radio from my wife kept telling me I was fast. So speedo reading 10klms fast showing 60 at 70 klms/hr
a bit faster at 80 nearly 95.

I had a Tom Tom GPS which I was using for speed indication. It clagged out and I will be purchasing a GPS speed indicator from Jaycar for just under $100. Nice and compact but most of all accurate. You may wish to consider this as a recalibration is usually in the order of $200 minimum.

Hi John
What is the TPM figure on the face of your speedo.

I took my car to Premier Instruments in Canberra, three times, paid them a heap of cash and gave up. They didn't fix it. I would like to say they fixed it because they're reasonable people but in the end they just didn't. I reckon I gave them a fair go.
I use a GPS to keep track of the speed. I understand there's a mob in Brisbane who recondition speedos.
Cheers,
David

The TPM figure is a number printed on the face of the speedo that states how many Turns Per Mile the speedo is calibrated for at the factory. Yours is probably 1408 which Minors were fitted with after 1962 (in the UK and NZ). If the primary speed figures are km/h, the TPKm is probably 800.
You can substitute the mechanism from another Smiths speedo with a different TPM to get the calibration correct without mucking around with the internals of your existing one (which is a very tricky job to get right). The Minor speedo is essentially the same as many other models (such as Mini speedos) which gives us a range of different TPMs to choose from.

Have you considered getting one of these? (or similar)
http://www.ebay.com.au/itm/PLUG-PLAY-HEAD-UP-DISPLAY-HUD-INTERNAL-GPS-12-VOLT-DIGITAL-LED-SPEED-WARNING-/182179926286?hash=item2a6ac5110e:g:IpIAAOSwnNBXahMu
This type does not depend on a linkage to your car's electronics like most on the market, so will work with your Minor or any car.
Jaycar sells one that is direct reading (does notwork by reflecting on the windscreen) and Repco has a special on a reflecting type for the next couple of weeks.
Most of these gizmos also allow you to set speed alarms. I have a couple of different models that I am pleased with.
Some would say why not just use a GPS navigator. The answer is that I have found that most of them have a tiny current speed display. It is dangerous searching for the speed on them. The type of speed indicator I am referring to above has a big display that you can place close to your line of sight.

Ii have a club run on Saturday to Parkes Swap meet and borrowed a GPS Tom tom.
Tried it today in my old ute found the speed very hard to read but I just want to see my actual speed. Wife is coming to Parkes
My speedo is going down to Manly Instruments for a calabration before Christmas.
All he needs is the number of times the cable turns in a 20 meter run.
I had my white speeo done here when I first built the car, what I did was dive two stakes along my driveway 20 meters apart then with the cable hanging out and one flat of square end painted white I got some one to count as I drove the exact 20 meters.
My Courier ute was 3 klms fast at 80-90-and 100 klms/hr
