Wheel Blotters and Mounting Flanges
Wheel blotters attached to both sides of reinforced
wheels are cushions needed to equalize the
pressure of the mounting flanges from wear if
slippage between the wheel and the flanges
occurs. The blotters are 108 mm (4 1/4
in.)
diameter. Take care that the blotters do not become
gouged or deeply scratched and that there is no
foreign material on them when mounting the wheel.
Emergency Applications
WARNING

Do not grind with a cut-off wheel or put pressure on the sides.

Do not mount wheel if blotters are damaged. Do not destroy
cushioning effect by making mounting bolts too tight.
Never fasten while applying your weight.
Otherwise the thread could be broken.
Proper torque is 25 N•m (250 kgf•cm) - 30 N•m (300 kgf•cm).

Examine wheel carefully before use.
Do not use if wheel is warped, damp, cracked, chipped or cutting
area shows heat discolouration.

Dropping a wheel can easily damage it.
Discard a wheel if you drop it.
Ring Testing Wheels
Cracks or defects in a wheel may not be visible. To help in verifying that a
wheel is OK to use, a “ring test”. Perform the ring test immediately before
mounting all new or used wheels.
Put your finger through the mounting hole to support the wheel. Use a non-
metallic handle of any small tool or a small piece of wood to lightly tap (do
not hit) the wheel in the locations shown in the illustration. Do not tap wheel
on the edge. Wheels without cracks will make a ringing sound, wheels with
cracks, or concealed cracks, will make a dull “clunk”.
IMPORTANT
If a wheel being “ring tested” is dirty or damp or
is tapped at the vertical centre line, the resulting
sound will be muffled and not reliable.
