Refurbishing that Odometer

Remove the gauge cluster assembly to the bench and detach the speedo unit as shown on the image (four tiny screws)

      Pull the unit out carefully to avoid scratching any paint or damaging the needle, which is very light material. It's usually best to have a replacement needle on hand if you plan on taking the old one off, as they're very easily damaged.

      With the face off, the speedo head can be removed with the 2 screws on the back

On to the odometer

      Remove small screws with care, and note the placement of everything:

Remove top bar	Remove gear	Remove Clip	Clip Off

Slide wheels out	Watch metal tabs stay aligned	Plastic tab on wheel

      With the wheel assembly out, it can be cleaned carefully [remember, it scratches easily], or new number strips can be applied.

      Wheels do not come off the shaft. They need to be kept aligned so the metal tabs don't move far --- which can break the plastic 'teeth' on the sides of the wheels that drive them properly. Also, clean all the gears well.

      After having a number of these units apart, I've come to the conclusion that there was no lubricant originally applied anywhere inside the speedo head. If you use anything, it will collect dirt and gum things up.

      And the speedo part - the magnet spins, pulling the bell against the tension of the coiled spring, the "calibrated" part. Best not to mess with it!!
