10.14 FRONT AND REAR TURN/SLIP PLATES
10.14.1 Visual Inspection

Check front turn tables and rear slip plates for unusual deflection, damage, fluid
spills.

Clean or further inspect if needed.
10.14.2 Clean Rear Slip Plates and Front Turn Tables

Clean foreign debris from front turn tables and rear slip plates by blowing out with
compressed air.

Check and clean steer plates. Lubricate with oil or light grease.
10.14.3 Maintenance of Rear Steer Plates

Inspect the non-skid coating on rear slip plates for wear. All areas found to be
worn smooth should be resurfaced with an Anti-Slip abrasive floor tread tape or a
heavy duty Anti-Slip Floor Coating.

Remove rear slip plate covers. Clean runway surface and touch up any paint
wear with a rust resistant paint. Allow paint to dry thoroughly. Inspect transfer
balls for excessive wear, deformations or corrosion.

Inspect plastic pads (pucks) for excessive wear or deformation. Replace if
needed.
10.14.4 Maintenance of Rear Steer Plates - If Equipped with Plastic
Bearing Cage

Remove top Slip Plate covers by first removing the four (4) shoulder bolts on
each cover.

Remove polyethylene-bearing cages insuring that all the Delrin bearings remain
in the cages. Additional Delrin bearings may be purchased if required.

Clean runway surface and touch up any paint wear with a rust resistant paint.
Allow paint to dry thoroughly.

To obtain optimum performance, the position of the slip-plate bearing cage
should be rotated every quarter to change the wear pattern.
o
With the first quarter maintenance, flip the bearing cage over to the
opposite side.
o
With the second quarter maintenance, rotate the bearing cage end-to-end.
o
With the third quarter maintenance, flip bearing cage over to the opposite
side.
o
Fourth quarter maintenance should see the bearing cage rotated back to
the original position.

Quarterly maintenance will optimize performance and contribute to longer slip
plate life.
10.14.5 Anti-Skid Coating on Rear Steer Plates

Inspect the non-skid coating on rear steer plates for wear. All areas found to be
worn smooth should be resurfaced with an Anti-Slip abrasive floor tread tape or a
heavy duty Anti-Slip Floor Coating.
