a. Drain (Refer to Figure 2-58)
The hydraulic system is pressurized. To prevent injury to personnel, gloves and eye
protection must be worn when working on hydraulic system.
Opening main hydraulic line before shutting off valve or draining hydraulic fluid from
reservoir will cause hydraulic fluid to drain from the system.
(1)
Verify that shut off valve (1) is OFF (valve handle 90_ to hose).
(2)
Place 55 gallon drum (or suitable container) (2) on passenger side of ECV next to main hydraulic
pump (3) in engine area.
(3)
Disconnect hose (4) by loosening nut (5) from elbow (6) below shut off valve (1). Remove and
discard O-ring from elbow (6).
(4)
Cut tie-down straps as required and insert elbow (6) attached to hose (7) into funnel in drum (2).
(5)
Open shut off valve (1). Hydraulic fluid will drain into drum (2).
(6)
When hydraulic fluid is no longer flowing into drum (2), remove elbow (6) attached to hose (7)
from funnel in drum (2).
(7)
Check sealing surface and groove of elbow (6) and nut (5) for damage or material build up.
(8)
Install new O-ring on elbow (6). Ensure O-ring is seated and retained properly.
(9)
Lubricate O-ring on elbow (6) with light coating of hydraulic fluid.
(10) Install hose (4) on elbow (6) and tighten nut (5) finger tight.
