Removal and Installation of brushes from your M1051
Your M1051 can accept wheels up to 10” in diameter and up to
3” in width. The machine has been designed to gang three, one
inch wide wheels at a time. When installing three wheels
together the width of the wheels are normally larger at the trim
(outside diameter) of the wheel, and your machine will
accommodate these wheels. The M1051 has a two inch arbor
size with factory installed (and removable with a 5/32” hex
key)
½
” x
¼
” keyways. Standard wheels from manufactures
such as Weiler can be ordered with this configuration. The
keyway allows for the wheel to be safely installed on the
machine without causing damage to the brush by having to
over tighten the wheel to maintain positive wheel drive.
If choosing to run widths that are narrower than 3” in
combined width you will need to install wheel spacers.
½
”
wide wheel spacers are available from Burr King.
1.
Unplug the machine from the power source. If your
machine is hardwired it maybe necessary to tagout the
machine while removing or installing the wheels.
2.
Release the clamp on the top of the brush cover and lift
the side cover plate from it’s resting ledge.
3.
Using a 3/16” hex key loosen the four cap head screws on the arbor cap. Remove the arbor cap.
4.
Pull the wheels off of the arbor. Ganged wheels will normally slide off as one wheel since the filaments
have intertwined during operation.
5.
VERIFY the brush or the wheel does not exceed the Maximum Safe Free Speed (MSFS) as rated by the
wheel manufacture. This is normally stamped on the flange of the wheel. MSFS (or RPM) is the
maximum speed at which the brushes may be used safely but is not necessarily the optimum speed for a
given application. Operating speed should be determined by the application.
6.
Install the brush on to the spindle using the arbor cap and cap head hex screws.
7.
Install the side cover plate and engage the latch.
8.
Verify the correct cap and adjust so the gap is less than 1/8”
9.
Spin brush by hand and check for interference and any foreign objects that maybe embedded in the
brush surface.
10.
Making sure the power switch is in the off position, plug the machine back in to the power source.
11.
Making sure the area is clear in front and behind the machine, with no person in front or behind the
wheel, run the wheel for 30-60 seconds. Check for vibration.
12.
Turn off machine and verify the four hex head cap screws are tight and other adjustments are still
proper. If no deficiencies are found return machine to service.
TIP: Self-Sharpening of Wire Wheel Brushes
When using wire wheel brushes without knots, periodically reverse the direction of rotation
to take advantage of the self-sharpening action that will result. Remove the brush from the
arbor, flip the brush 180° and remount the brush securely. *
