HYDRAULIC SYSTEM
(See figure 3)
1. Oil Specification: CITGO Transgard Tractor
Hydraulic Fluid - Material Code 633310001 .
2. Capacity: 40 gallon.
3. Maximum allowable operating temperature
240°F.
4. Check the oil level in the reservoir daily. It
should be maintained 1” from the top level on
the sight gauge.
5. Oil is added through a filter screen inside the
filler neck. Before filling, remove the screen,
inspect and clean if required.
6. Carefully clean dirt from the return filter head
and element. Replace the filter element every
500 hrs of operation.
7. Drain reservoir and refill with new oil every
2000 hrs or annually, whichever occurs first. If
the oil becomes contaminated and appears
milky colored, replace immediately.
8. Every 100 hrs of operation, inspect all hydraulic
hoses, hose connections, pump seals and mo-
tor seals for leakage. Tighten loose connections
and replace damaged components.
9. A ball valve is provided at the bottom of the res-
ervoir where the suction hose is connected.
Turn this valve off to service hydraulic compo-
nents. This prevents draining of the reservoir,
however it is necessary to catch the oil that
drains from disconnected hoses into a suitable
container for proper disposal. Always check
and refill the reservoir as required when servic-
ing is completed.
Rear Gate Flashing
(See figure 4)
1. Swinging gate flashing strips are clamped to
both vertical ends of the rear gate frame. These
strips must bear against the vertical box sides
to minimize leakage.
2. To adjust, loosen the six 3/8" carriage bolts
clamping the flashing.
3. Move the flashing strips so they contact against
the box wall and retighten bolts.
