Maintenance
Screed Extensions, Slides Or
Bushing Replacement
NOTE: When replacing bushings, the bushings need to
be honed if 1-1/2” rods (Figure 10-38,4) do not
slide in.
Removal
1. Remove cylinder covers (Figure 10-29,19,20).
2. Run screed extension out completely.
3. Remove cylinder pin (Figure 10-48,3).
4. Remove the four 1/2” bolts (Figure 10-38,9) lock
washers (Figure 10-38,8), and at washers (Figure
10-38,7) in extension rods (Figure 10-38,6)
holding the extension on.
5. After bolts have been removed, pull extension out of
the way.
6. Pull 1-1/2” rods (Figure 10-38,6) out of slide (Figure
10-38,2).
7. Loosen ve bolts attaching top guide (Figure 10-
29,17). This will let main slide (Figure 10-38,2)
come out easily. At this time bushings (Figure
10-38,4) can be replaced or main slide can be
replaced.
Installation
1. Clean area where slides (Figure 10-38,2) are
installed, and lubricate before reinstalling the slide.
2. Loosen guide (Figure 10-38,17) and drive guide
down tight against slide by using allen set screws.
3. Slide 1-1/2” rods (Figure 10-38,6) back into slide
(Figure 10-38,2).
4. Secure rods (Figure 10-38,6) with capscrew
(Figure 10-38,9) lock washer (Figure 10-38,8),
and at washers (Figure 10-38,7).
5. Make sure extension is mounted ush with bottom
of screed plate.
6. Hook cylinders (Figure 10-48,1,2) back to
extensions using pin (Figure 10-48,6) and put
cylinder cover (Figure 10-29,19,20) back on.
7. Run extension out and grease the extension well
before operating “in” and “out”.
Screed Wear Plate Replacement
Removal
1. Run screed extension all the way in.
2. Remove the cylinder covers, (Figure 10-29,19,20)
the walkboards (Figure 10-37,1), and the screed
lids (Figure 10-29,7).
NOTE: For electrically heated screed, remove all wiring
and heating elements.
3. Remove the twenty-four (24) 3/8” bolts holding the
wear plate (Figure 10-29,13) to the screed frame
on each side.
4. Clamp the center portion of the screed frame so
that when the screed frame is raised up off the worn
wear plate the clamp will hold the frame in place.
5. Raise the screed up and remove the worn wear
plate.
6. Clean all material buildup from the screed frame
before bolting in the new wear plate.
Installation
1. Set the new wear plate down level on 3 blocks,
placing one block in the center and one at each end.
Make certain the extensions are raised all the way
up to prevent extensions from holding the screed
frame off the wear plate.
2. Lower the screed frame down on the new wear
plate.
NOTE: Do not tighten the bolts in the next step until all
the bolts are installed.
3. Install six bolts in one side at the front to hold the
wear plate.
4. Loosen the vibrator on the slotted side and adjust
the crown. This will move the screed frame in and
out on the wear plate to help align the bolts on the
opposite side.
5. Once the front bolts are installed install the rear
bolts.
6. When all of the bolts have been started make sure
the screed frame and the wear plate are at.
7. Torque bolts to 55 ft. lbs. (74 N•m). Start inside and
move outward by rotating from the left to the right
side. This will keep the screed relaxed.
NOTE: Install all wiring and elements if electric.
8. Place the screed lids, the walk boards and the
cylinder covers back on the screed.
