Inspection, Maintenance and Adjustment 4-11
The hydraulic oil filler cover also serves as the
hydraulic oil strainer access cover. It is important
to replace this cover and the components in the
proper order and alignment.
The filter element (2, Figure 12), retaining rod
(2) and spring (4) are assembled as shown in
Figure 12. The hole (1) in the base of the filter
element fits over a circular base in the bottom of
the reservoir. The retaining rod (3) screws into
the top of the filter element (2), but the spring (4)
slides over the top of the rod. Be certain that this
spring does not fall into the tank during
reassembly.
1.
If filter assembly was removed, insert
assembly into the reservoir and check to
make sure it is securely in place.
2.
Check O-ring for damages and replace if
necessary. Check position of O-ring at
surface of hole.
3.
Place the cover on the access hole. Make
sure the spring retaining cup (1, Figure 13)
in the lower section of the cover is lined up
with the spring. The filter assembly rod
must be in a vertical position and
perpendicular to the base of the reservoir.
The cover can be rotated to align the rod
into a vertical position.
4.
Tighten mounting bolts to 4.84 kg•m (35 ft
lb).
CHECK FOR LEAKS IN THE HYDRAULIC
SYSTEM
1.
Perform a daily walk-around inspection to
make sure that the hoses, piping, fittings,
cylinders and hydraulic motors are not
showing any signs of leakage. If any is
noted, determine the source of the leak
and repair.
