IMPLEMENT AND STEERING HYDRAULIC SYSTEM CONTINUED
Hydraulic Tank and Filter
00011
The hydraulic oil tank (Figure 8, Item 1) is located on the front of the right fender of the machine and is sealed in
order to prevent contamination of the hydraulic oil. The suction port (Figure 8, Item 6) supplies hydraulic oil to the
hydraulic pumps. Oil flows from the hydraulic components into hydraulic oil tank (Figure 8, Item 1) through five
passages.
One passage (Figure 8, Item 7) collects oil from the pressure reducing valve. This passage (Figure 8, Item 7) also
collects oil from the pilot control valve (bulldozer angle), if equipped. Oil from this passage (Figure 8, Item 7) flows
directly into hydraulic oil tank (Figure 8, Item 1).
Another passage (Figure 8, Item 8) collects implement return oil that drains through the inlet manifold. Oil from this
passage (Figure 8, Item 8) flows into the hydraulic oil tank (Figure 8, Item 1) through the implement return oil filter
(Figure 8, Item 5). The implement return oil filter (Figure 8, Item 5) stops any debris that is in the hydraulic oil.
Another passage (Figure 8, Item 9) collects return oil from the following sources:
Case drain from the implement pump
Case drain from the steering motor
Oil from this passage (Figure 8, Item 9) flows into hydraulic oil tank (Figure 8, Item 1) through the case drain filter
(Figure 8, Item 3). The case drain filter (Figure 8, Item 3) stops any debris that is in the hydraulic oil.
A fourth passage (Figure 8, Item 10) collects pilot return oil from the pilot control valves. Oil from this passage
(Figure 8, Item 10) flows directly into the hydraulic oil tank (Figure 8, Item 1).
The fifth passage (Figure 8, Item 11) collects pilot return oil from the implement control valves and from the pilot
manifold. Oil from this passage (Figure 8, Item 11) flows directly into hydraulic oil tank (Figure 8, Item 1).
A port at (Figure 8, Item 12) is for the temperature sensor.
