4.3 HYDRAULIC FLUID AND FILTER - INSPECT, REPLACE.
THIS TASK CONSISTS OF.
a. Checking fluid level b. Fluid draining
c. Fluid filling
d. Filter removal
e. Filter installation
INITIAL SETUP
Tools:
Equipment Condition:
Toolkit, General Mechanics (item 5, Section III, Appendix B).
Hydraulic fluid tank access cap (1) removed.
Shop Equipment, Automotive Maintenance and Repair:
Engine stopped and cool.
Organization Maintenance, Common No. 1, less power
(item 6, Section III, Section III, Appendix B).
General Safety Requirements:
Material/Parts Required
WARNING
Hydraulic fluid filter, item 15, Appendix E.
Lubricating oil, item 7, Appendix E.
Hydraulic fluids are toxic and flammable.
Hydraulic oil, item 8, Appendix E.
Do not use near heat or open flame.
Area should be well ventilated. DO NOT SMOKE.
a. Checking fluid level. Refer to figure 4-2.
1) Remove dipstick (3), wipe clean then reinsert.
2) Remove dipstick (3) again. Fluid level should be between marks on dipstick. The distance between
the marks represents approximately 4 gallons/15.1 liters. Filling to the top mark represents the full
capacity of 25 gallons/94.6 liters.
3) Replace dipstick (3).
b. Fluid draining. Refer to figure 4-2.
1) Raise the hydraulic power supply high enough to put the waste fluid container underneath.
2) Turn the drain valve handle (4) counter clockwise allowing the hydraulic fluid to drain in to the waste
fluid container. Turn the drain valve handle fully clockwise to close the drain valve after all the fluid has
drained.
3) Examine the waste fluid for evidence of metal particles which would indicate possible pump failure.
Dispose of the fluid in accordance with local SOP.
c. Filling. Refer to figure 4-2.
1) Remove filler cap (2).
2) Add fluid through the filler to the full line on the dipstick (3). The hydraulic fluid tank capacity is 25
gallons/94.6 liters.
