The pages on this site are not meant to be
a tutorial for restoring your own gauges, they are here to show the steps
performed when you entrust us with your restoration work.
The
first pictures show what a typical gauge looks like when we receive it.
The
first thing we do is visually inspect it for damage, and then bench test it for
accuracy. In this example the lower base mount bolt is bent.
This
76 Kawasaki KZ900 A4 Tachometer was tested at two different RPM’s and is accurate. Next
step is to remove the stainless steel connector ring, and split the two halves.
 This
Tachometer is dented on the lower base mount and the inner and outer cones are
dented also. All three require replacement.
Next
we remove the needle and the faceplate.
Here
we note that although the faceplate is faded, and has paint chipped away from
the two mounting screws, it can be restored to look new. Careful inspection is
given to the underneath of the faceplate, in search of cracks.
As
you can see by another example, the cracks on the top side of the Kawasaki Z1 faceplate are
barely noticeable.
However
when turned over, they are very apparent. Faceplates that are cracked this way
cannot be used. They will fail in short order.
The following picture shows a
stripped down drive unit.
Notice
the round cylinder directly atop the spring. This is the internal ‘damper". If
your gauge has a needle that "wanders",...at speed or RPM, and your cables are
good,....this is the culprit. The damper itself holds oil, and cannot be fixed,
unless this whole drive unit is replaced with one that works properly.
