Speedo recalibration
 

Hi all,
My truck has 315/75 R16 rubber fitted and so the speedo is out,
enough to get fined.:-arrgh
It also makes keeping an eye on fuel consumption difficult.
Is there a way to recalibrate the speedo or do I need to buy one of these?

There isn't a way to correct the speedo on theses trucks. (newer ones can get the speedo reprogrammed)

How much is your speedo out?

Enough to get fined, when the speedo says 100km the GPS says 112km.

U can recalibrate with AE which I have. Where do you live ??
Never mind I just saw the city of churches. No good to you
Might ask Reg if he has it

Brian,
Pardon my ignorance but what's AE?:o

This:

Adrian,
WOW what and great piece of equipment!!

Unfortunatley its a bit of overkill just to recalibrate the speedo.
I don't know if I would get enough use out of it to warrant the
cost and freight to Australia.

its well worth the money imo. has full diagnostic provisions, data logging and much more. Its the first thing I get out when i got a problem with the truck. Saves some yobbo charging you $100 bucks an hour and changing parts will nilly. Get ya data, post your problem on FTE and problem solved.

Analogue speedo recalibration:
1) check GPS and indicated speed difference at 100kmh;
2) remove insturment binnacle cowl;
3) carefully remove speedo needle rest pin (pull gently with needle nosed pliers);
4) let needle come to it resting position, note position;
5) using a lifting fork, gently level the speedo needleaway from the cluster - without too much effort the needle will come off;
6) refit the needle to a new position to obtain the speed differential correction as noted in 1) above, the needle just presses on;
7) re-fit cowl & binnacle cover;
8) next time you're on the highway check the speed differential again, if necessary repeat the above until you have 100kmh spot on.

If you are running larger than stock wheels the above will mean that your speedo will proportionally read UNDER your GPS/actual speed below 100kmh.

If my memory serves me correctly we dont have a instrument cowl. Its all one bloody big piece and a absolute PIA to get off

Simon,
Mate ifs that's the only solution then the AE suddenly sounds like
an attractive option.

Brian,
From my experience anything involving the dash of any vehicle is a PITA, and the neck and the back and, by the end, the head.
The dash has to be my least favourite place.

It's not that hard! Prize out the headlamp switch and unplug it, the entire cowl (including dash) unclips, once you get it started it is easy to unplug the 4WD loom, twist it over and stick it on the passenger seat. From there you can unclip the perspex instrument cover and access the gauge needles.
I've had this lot out countless times & replaced all the bulbs with LEDs cause then I figured that I wouldn't have to do it again.
The actual dash stays in situ.

Anyway, I have to take mine off again because one of the LEDs is flashing - why did I bother? So I'll take some pics of the operation and post them.

Bought the AE from RR, waiting for it to arrive.:)
How hard is it to recal the speedo with the AE?
