LeeBoy Model 8616 Conveyor Paver 7-13
Maintenance
Track Tension Adjustment
Adjustment should only be done by an
authorized LeeBoy Dealer.
1. Locate main hydraulic valve on left side of paver,
inside door.
NOTE: Track tension is set on the main manifold which
is located at hopper end of electrical valve
manifold.
NOTE: The following adjustment should only be
performed if track jumps in reverse.
2. Tension pressure is set to 1200 PSI. If adjustment
is needed, locate pressure reducing valve (Figure
7-9,2) on left side of main manifold facing outside.
3. Remove valve cap with allen head screw driver.
Do not screw valve adjuster out below
900 PSI or all pressure will be lost to tank, causing a
heat problem.
Too much track tension pressure
will cause premature wear on the chains, idler and
sprockets.
4. Adjust exposed socket IN (CW) for more tension
and OUT (CCW) for less tension.

Do not screw valve adjuster out below
1200 PSI or all pressure will be lost to tank, causing
a heat problem.
Too much track tension pressure
will cause premature wear on the chains, idler and

3. Adjust exposed socket IN (CW) for more tension
and OUT (CCW) for less tension.
NOTE: Track tension is controlled by a load sense
pump. The pump is operating all cylinders.
