5-10 LeeBoy Model 8510E Conveyor Paver
Maintenance
Torque Hub Hydraulic Motor
Gear Adjustments
Torque hub hydraulic motors are
calibrated and set at the factory. These adjustment
should only be performed by an authorized LeeBoy
dealer. Work not performed by an authorized dealer
can damage machine and void the warranty.
The low gear adjustment must be made to the slow
side drive motor only. The low gear adjustment screw
is located on the bottom of the drive motor. Make only
small adjustments at a time.
Your authorized LeeBoy dealer will perform the tracking
adjustment on the high side gear by adjusting the screw
on the top of the hydraulic motor. This adjustment on the
motor for the fast track must be screwed in to equalize
track speed.
Your LeeBoy dealer will perform the following
procedure to adjust either gear:
1. With paver running, push the 2-Speed switch:
• Set switch to the LOW position if adjusting
low gear. (The blue 2-Speed light should not
illuminate.)
• Set the 2-Speed switch to the HIGH position if
adjusting high gear. (The blue 2-Speed light will
illuminate.)
2. Adjust screw (on bottom of the hydraulic motor for
low gear; on top for high gear) until you feel back
pressure on the adjustment screw. This indicates
the correct adjustment is close.
3. Finalize adjustment by making a one-quarter
(1/4) turn at a time until the correct adjustment is
accomplished. Recheck tracking.
NOTE: If hydraulic motor has not been previously
set, ten revolutions of the adjustment screw may be
required before noticing any difference in travel.
Conveyor Switch Adjustment
Small adjustments may be necessary to conveyor
switch for optimum conveyor performance. (Figure
5-10) There are two positions of the conveyor ap:
One upper, shutting the conveyor OFF; and one lower,
turning the conveyor ON.
• When correctly adjusted, the conveyor shuts off when
the paddle is approximately eight (8) inches (20.3 cm)
from the top of the conveyor switch to the bottom of
conveyor paddle; and turns on when the paddle drops
to approximately 12 inches (30.5 cm).
