Instructions for “No-Sweep™”
Spindle Adaptor
The “No Sweep” caster camber gauge has a ‘bar’ on the face of the black
screw-on adaptor. This engages with the groove in this
Spindle Adaptor
to
position the gauge correctly on the spindle. This allows you to read caster
directly without turning the wheels. It is installed inside the tubular spindle,
sticking out 1/16” to engage the ‘bar’.
To install this
to know what the caster is on each spindle and install the
Spindle Adaptor
(one is installed in each spindle) you will need
Spindle Adaptor
so the gauge reads caster correctly. An easy way to do this is to use another
caster camber gauge to check what the caster currently is (see below for an
alternate method).
Step1: The
Spindle Adaptor
is held inside the spindle by tightening the
single Allen bolt in the center with a 1/4” Allen wrench. As you tighten this
bolt the triangle shaped ‘feet’ around the outside will expand to hold the
Spindle Adaptor
in place. See Figure A.
Step 2: Tighten this bolt (a drop of BLUE Loctite™ will keep the bolt tight) until
the
Spindle Adaptor
they are equally spaced around the outside. Install it in the spindle so that it
sticks out 1/16”, the bottom of the groove is flush with the end of the
spindle, and the groove is approximately level (ideally close to the same angle
as your caster). Tighten the center bolt. See figures B & E.
will just slide into the spindle and rotate the feet so
Step 3: Now install the gauge, screwing it on to the spindle, engaging the
bar on the face of the screw-on adaptor with the groove in the
. Hand tighten only. Read the caster on the gauge. If it does not read the
tor
correct caster remove the gauge and loosen the 4 small round headed Allen
screws inside the face of the
Spindle Adaptor
to rotate slightly and is for fine adjustment. Snug up these
Spindle Adaptor.
This allows the face of the
4 small screws so that you will still be able to turn the face of the
Adaptor

Step 4: Reinstall the gauge (hand tight again) and rotate the gauge until the
caster reads correctly (as you rotate the gauge you will also rotate the
Adaptor
face). Remove the gauge tighten the 4 round head screws. Reinstall
the gauge to confirm the correct reading. If you do not have enough fine
adjustment with the 4 round head screws loosen the center bolt and rotate
the entire
Spindle Adaptor
slightly. Repeat the fine adjustment as needed.
See figure E.
