Step 1

Remove the rear demister and dash light dimmer (blue arrows) and undo the screws the red arrows are pointing to to get the cluster cover off. You need to remove the top scew covers.

STEP 4


Separate the cluster, start by removing carefully the black knob by pulling the end off, from the odometer reset. Then undo the screws that the red arrows point to. Remove the two globes. (yellow arrows) Press down on the cluster facia tabs on the top and bottom (green arrows)

STEP 5

Separate the facia from the deck. Carefully lift out the speedo assembly taking extra care not to touch the needle or the face. You dont want to bend the needle or leave finger prints on the display of the speedo.

STEP 6

With your small long nose pliers hold the shaft of your speedo, then gently move the needle up or down, depending on which way your speedo is out. UP if it was reading to slow and down if its reading to fast.

What I did was I put the speedo only in the car, connected it to the speedo cable, turned on the GPS and went for a drive, got a feel for how far out the speedo was. in this case it was slow by 6km/h. I drove the car to 60km/h according to the speedo and the GPS said 54kms, so I pulled over with the long nose pliers I held the speedo shaft, and moved the needle up 6kms, retest and repeated until I was happy with the result.

STEP 7

Finally this speedo does not have a pin to stop the needle at 0km/h so I had to adjust the needle rest position but using a phillips head screwdriver. Because of me moving the needle while the shaft was locked, the rest position changes.

Look inside the yellow circle and move the metal arm adjusting the 0 km/h needle position.

Do this last after your final needle adjustment.

Surely you can keep the car at the same speed for 5-10 seconds ;)

lerroy, you dont make any adjustments while driving

if you have a bouncy needle on a cable system, you undo the nut on the cable near the firewall and spray CRC down both ends, sometimes pull out the inner cable from the dash side, clean and lube it and put it back in. :)
