LeeBoy Model 8616 Conveyor Paver 7-11
Maintenance
High Gear
NOTE: The high gear adjustment screw is located on
bottom of drive motor.
Adjustment should only be done by an
authorized LeeBoy Dealer.
Tracking adjustment on the high side gear is performed
by adjusting the screw on bottom of hydraulic motor.
The adjustment on the motor for the fast track must be
screwed in to equalize track speed.
NOTE: If hydraulic motor has not been previously set,
ten revolutions of the adjustment screw may be
required before noticing any difference in travel.
NOTE: High gear operation requires the 2-SPEED ON/
OFF switch to be in the ON position.
1. With paver running, push the 2-SPEED ON/OFF
switch to ON to activate the HIGH gear.
2. Adjust screw on bottom of hydraulic motor until back
pressure from spool is felt on adjustment screw.
This indicates adjustment is close.
3. Finalize adjustment by making one quarter (1/4) turn
at a time until correct adjustment is made.
Torque Hub Lubrication
NOTE: See also 100-Hour or Monthly Routine
Maintenance.
1. Check oil level in the torque hub, by removing the
plug at the 3 o’clock position. If oil comes out, no oil
is needed. Insert plug and tighten.
2. If oil does not come out, remove the plug at the 12
o’clock position and ll torque hub with 80W-90
gear lubricant until oil starts to appear at the other
hole.
3. Replace both plugs and repeat process on other
torque hub.
Conveyor Drive Chain
Adjustment
1. Operate conveyors.
2. Look at drive chain from side of paver at rear track.
If drive chain has excessive loose motion in it,
adjustment is necessary.
Entanglement / Sever Hazard! Make
sure the paver is shut off and the key is taken out the
key switch. Never perform any adjustments on the
paver when it is running.
3. Shut off paver if adjustment is necessary. Loosen
the jam nuts (Figure 7-7,2) on the chain adjuster.
Turn the chain adjuster (Figure 7-7,1) to loosen or
tighten the chain. Do not overtighten; leave about
1/4” (6.35 mm) of slack in chain.
4. Retighten jam nuts (Figure 7-7,2) when adjustment
is made.
5. Perform the same check on the opposite conveyor
drive chain.
6. Keep chains clean from buildup, adjusted properly
and lubricated.
