Wear Strip

„

NOTE: The skid frame should be removed for

this procedure.

„

NOTE: Prior to removing the wear strips, inspect

each wear strip for wear. The wear strip must be
10.7 mm (0.42 in.) thick or thicker. If the wear strip
measurement is less than specified, replacement
of both wear strips is necessary.

0727-726

„

NOTE: It is possible to remove and install a wear

strip without removing the skid frame. To do this,
remove the machine screw and lock nut securing
the wear strip at the front of the slide rail; then
align the wear strip with openings (windows) in the
track and drive it rearward off the slide rail. Apply
low-temperature grease to the new wear strip and
slide rail; then align the wear strip with openings
(windows) in the track and drive it forward onto the
slide rail. Secure with the machine screw and lock
nut tightened to 1.1 kg-m (8 ft-lb).

1. Remove the machine screw and lock nut securing

the wear strip to the front of the slide rail.

AG298D

2. Using a pipe wrench and starting from either end,

hook the edge of the wear strip with the pipe

wrench jaw and twist the wear strip off the slide

rail. Move the pipe wrench 7.5 cm (3 in.) and

again twist the wear strip off the rail. Repeat this

procedure until the wear strip is free of the rail.

„

NOTE: The wear strip can also be driven off the

slide rail; however, it is quicker to use a pipe
wrench.

CLEANING AND INSPECTING

„

NOTE: Whenever a part is worn excessively,

cracked, or damaged in any way, replacement is
necessary.

1. Clean the slide rail using parts-cleaning solvent

and compressed air.

2. Inspect the slide rail for cracks. If any cracks are

found, replace the slide rail.

3. Using a straightedge, inspect the slide rail for any

unusual bends. Place the straightedge along the

bottom surface of the slide rail. If the rail is found

to be bent, it must be replaced.

4. Place the straightedge along the side of the slide

rail. If rail is found to be bent, it must be replaced.

INSTALLING

„

NOTE: Apply a light coat of grease to the slide

rail surface to aid in installing new wear strips.

1. Starting from the back, start the wear strip onto the

rail; then using a block of wood and a hammer,

drive the wear strip forward into position.

2. Secure with a machine screw (coated with red

Loctite #271) and lock nut. Tighten to 1.1 kg-m

(8 ft-lb).

! WARNING

Always wear safety glasses while using com-
pressed air.
