LUBRICATION AND MAINTENANCE

9. Retighten hinge plate bolts. Make sure the bottom
edge of hinge support plate is in full contact with
support. Weld the front vertical edge of each hinge
plate to the mounting plate with a 3/16" fillet.
Adjusting the Tailgate Latches (See Figure 2)
1. Close tailgate completely and lock the latches with
the hydraulic control.
2. All latches should be in the same contact position
with the cam roller. The latch should contact the
cam roller to maintain a 1/8" gap between the roller
and the machine edge of the latch pin. See Figure 2.
3. If there is a latch which is not in the same contact
position, an adjustment will be required.
4. Adjust by removing the hairpin retainer and pin from
the central cam end of rod.
5. Release latches and loosen clevis locknuts on each
end and rotate each clevis equally as both are right
hand threaded. Replace pin and hairpin and check
engagement.
6. Adjust so that the flat on each locking cam is
completely under the body bracket roller. Exact
sequence can vary but keep all engagements equal
throughout this process.
7. When correct engagement is achieved, tighten clevis
locknuts securely and make sure that hairpin
retainers are in place.
8. If the tailgate gasket is leaking, the latch in the area
of the leak must be individually tightened. They are
shim-adjusted, with standard 5/8" flat washers. After
fully opening latches, remove the wedge roller bolts
and add a flat washer. Retighten roller bolts securely
and recheck wedge adjustment, as above. Recheck
leakage and repeat roller adjustment as necessary.

Ejector Plate Slide Pad and
Wiper Adjustment
The ejector plate slide pads should be adjusted or
replaced whenever the end of the angle iron guard over
the pusher cylinder can be moved up and down 1/2" by
hand while the plate is at the narrowest point of its travel.

CAUTION
1. Open tailgate and support it on its props. Clean the
debris body, ejector plate and slide pad assemblies
with pressurized water. Fully retract ejector plate.

2. Enter body through tailgate and measure distance
between guide rails every 18" to determine narrowest
point. Exit from body and move the plate to this point.
3. Remove pad cover and check pad thickness to
determine if replacement is necessary. A pad should
be replaced when there is less than ¼" of pad behind
the pad covers (See FIG. 1.) If so, loosen adjusting
bolt lock nut and loosen 1-1/8 hex adjusting bolt,
upper and lower pads. FIG. 2.
Failure to maintain proper slide pad adjustment can
result in premature ejector plate failure not covered
by warranty.
Failure to securely support tailgate whenever working
beneath it may cause injury or death.
Shut truck engine off and pocket the keys EACH
TIME that the body must be reentered or when
working under the raised tailgate. Failure to do this
could result in injury or death.
