If the Vertical Shaing Gauge has been
twisted by some reason, it will contact
only either edge of the rim.
Even in this condition, you can
continue the wheel truing job without
any problem, but if you want to have
the gauge contacts both edges at
once, twist the gauge.
!
Turing wheels means the gauge has to touch the
rim and this may cause some light scratching.
If you use an expensive carbon rim and you don't
want to scratch it, flip the metal piece on the Side
Shaking Gauge. In this position, only the plastic
arm body contacts the rim and it won't damage
the rim. (see Fig. F)
The contact sound between the tool and rim will
become fainter and more difficult to hear.
The angle of the gauge arm should be set as deep
as possible. (see Fig. G)
If the Vertical Shaking Gauge touch the tire, fold
it down or remove the tire.
Vertical Shaking Gauge
Vertical Shaking Gauge is for checking the vertical
movement of the wheel.
The purpose of this job is making the wheel
concentric circle to make the riding smoother.
You must remove the tire from the wheel when
doing this job.
Raise up the Vertical Shaking Gauge Arm (and
extend the arm length by turning the center barrel
type knob if necessary) to position the tip 1 - 2mm
away from the rim edge (do not touch). (see Fig. H)
Rotate the wheel slowly (do not spin fast) and
look at the clearance between the rim edge and
the gauge tip. The gap will change vary and when
the rotating wheel comes in contact with the
gauge, you will hear a scratching sound.
Turn the nipples to make this gap equal on all
around the wheel.
(Fig. H)
The gauge arm angle against the rim should be as
deeply as possible.
Turing wheels means the gauge has to touch the
rim and this may cause some light scratching.
If you use an expensive carbon rim and you don't
want to scratch it, remove the metal bracket from
the Vertical Shaking Gauge and only the plastic
part contacts the rim.
Be sure the contacting sound will have to become
very small and difficult to listen.
