5-30 LeeBoy Model 8510E Conveyor Paver
Maintenance
Main Screed Wear Plate
The screed wear plates can wear out over time and
must be replaced if the plate has worn to less than
1/4-inch thick. Poor maintenance, paver cleaning,
asphalt mixes containing hard aggregate and improper
material flow can contribute to excessive wear on the
main screed and extension wear plates. Correct screed
heating also helps prevent excessive material build-up.
An uneven, worn screed plate will produce an inferior
mat
1. Retract screed extension completely.
2. Unbolt and remove the rear walk boards.
(Figure
5-39)
3. Unbolt and remove upper and lower screed covers.
4. Remove bolts on the heating element covers and
remove. Disconnect wiring.

7. Raise the screed completely.
8. Slide the worn wear plate from under the screed.
9. Clean all material buildup on the screed frame.
10. Set new wear plate level on three blocks, placing
one block in the center and one at each end.
11. Lower the screed frame down onto the new wear
plate.
12. Install center and side bolts first (front and rear)
to hold the new wear plate in place, then install
remaining bolts.
DO NOT tighten the bolts until all
bolts are installed.
13. Loosen the plate on the slotted side to 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.
14. Install the remainder of the front bolts, then install
the rear bolts, ensuring the screed frame and wear
plate are flat.
15. Torque bolts to 55 ft lbs (74 N•m) starting inside,
then moving outward, by rotating from the left to the
right side to keep the screed relaxed.
16. Reinstall the screed covers in reverse order, then
the walk boards.
