Measurement
Genie specifications require that this procedure be
0.063 inch
performed annually.
1.6 mm
0.055 inch
Maintaining the axle wear pads in good condition is
1.4 mm
essential to safe machine operation. Wear pads
0.043 inch
are placed on axle tube surfaces to provide a low
1.1 mm
friction, replaceable wear pad between moving
0.094 inch
parts. Improperly shimmed wear pads or continued
2.4 mm
use of worn out wear pads may result in
0.150 inch
component damage and unsafe operating
3.8 mm
conditions.

1 Start the engine from the platform controls and
extend the axles.
2 Measure each axle wear pad.
3 Replace any wear pad if it is less than
specification. If a wear pad is not less than
specification, shim as necessary to obtain
minimum clearance and no drag.
4 Extend and retract the axles through the entire
range of motion to check for tight spots that
may cause binding or scraping of the axle
tubes.
Note: Always maintain squareness between the
outer and inner axle tubes.
