7-32 LeeBoy Model 8510B Conveyor Paver
Maintenance
Rear Conveyor Shaft
Replacement
Removal
1. Rotate ight chains (Figure 10-3,12) until C-188
master pin (Figure 10-3,15) is located. When
located, rotate the master pin to the rear of the
conveyor drive sprocket.
NOTE: If the shaft (Figure 10-3,8) is broken, the front
shield with rubber needs to be removed, then
push against the outer edge of the conveyor bars
to make the chains rotate.
2. Remove grating walkway from paver so that you can
reach in to the center of conveyor at rear, or lay in
under engine platform to reach center.
3. Push back the rubber shield at the center of the
conveyor at the rear so that the snap ring (Figure
10-3,9) can be removed off the shaft.
4. Run screed extension out fully on side to be
changed.
NOTE: The front screed arm bolt may need to be
removed to tilt arm out of the way.
5. Remove the chain guard and 80 chain that drives
the conveyor.
NOTE: The ight chains can be loosened to allow the
shaft to come out easier.
6. Remove capscrew (Figure 10-3,1) and countersunk
washer (Figure 10-3,2) then remove the outer 80
drive sprocket (Figure 10-3,3).
7. Remove the four capscrews (Figure 10-3,10) and
washers (Figure 10-3,11), then remove conveyor
mounting plate with bearing (Figure 10-3,4).
NOTE: Do not remove the master pin on the inner C-188
chain. Let the sprocket and chain stay together.
8. Remove C-188 master link (Figure 10-3,13) and lay
the chain away from the sprocket on the outer side.
9. The rear shaft (Figure 10-3,8) and outer C-188
sprocket (Figure 10-3,5) will pull straight out at this
time.
Installation
1. Slide the new shaft (Figure 10-3,8) in and align
the inner C-188 sprocket (Figure 10-3,6) onto the
spline shaft.
2. Install the snap ring (Figure 10-3,9) on and fasten
the rubber shield back.
3. Install the outer C-188 sprocket (Figure 10-3,5), be
sure that the teeth are in line with the inner C-188
sprocket.
4. Install the pivot bearing plate (Figure 10-3,4) using
the four capscrews (Figure 10-3,10) and lock
washers (Figure 10-3,11).
5. Apply thread-locking adhesive on taper head bolt
(Figure 10-3,1).
6. Attach the outer drive sprocket (Figure 10-3,3) with
taper headed bolt (Figure 10-3,1) and countersunk
washer (Figure 10-3,2).
7. Put 80 chain on and lubricate the chain.
8. Adjust chain for about 1/4 in. (0.64 cm) play.
9. Place chain guard back on.
10. Hook screed arm in place.
11. Adjust main ight chains and let the conveyors run
for a short period of time. Then recheck the chain
adjustment.
12. Place grating back on when nished.
NOTE: Conveyors should be adjusted about every 100
hours to avoid damage to the conveyor rear
shafts and the chains.
NOTE: Keep the conveyors clean and well lubricated.
NOTE: If the conveyor or ight chains are adjusted all
the way out, locate the master link and remove
it. Remove 1 block link and 2 sidebars on each
chain, then replace with C-188 1/2 links. (There
is not enough room to take a link out without
installing a 1/2 link back).
