High-Pressure Tube Isolation By Cap Or Plug.

TM 5-3835-222-BD

e. Check that the hydraulic reservoir level is at least at the minimum operating level. if this level

is low, refer to para 8-13 and fill the reservoir as needed.

f. Operate all hydraulic subsystems (except those that may still be damaged) to remove air from

the system. Check carefully for fluid leaks. Tighten leaking fittings.

g. Check the hydraulic reservoir again to ensure a sufficient hydraulic fluid leve. if this level is low

refer to para 8-13 and fill the reservoir as needed.

h. Record the BDAR action taken. When the mission is completed, as soon as practicable,

repair using standard maintenance procedures.

Hydraulic Tube Isolation. The following options explain how to isolate damaged hydraulic

tubes. Before isolating a tube, determine what effect the isolation will have on the capabilities of

the system. Use one of the following options to isolate a hydraulic tube. Determine if the damaged

tube is high-pressure or low-pressure tube. Damaged high-pressure tubes require high-pressure

isolation. Damaged low-pressure tubes may be isolated by either high- or low-pressure isolation;

however, high-pressure isolations are preferred.

8-8.1. High-Pressure Tube Isolation By Cap Or Plug.

Personnel/Time Required:

1 soldier 25 minutes

Materials/Tools:

Tool Kit (appendix C, section ii, item 25)

Plug (appendix C, section ii, item 25)

Procedural Steps:

a. Remove the damaged hose with an adjustable wrench.

b. install a plug or cap where the tube was previously connected.

c. Tighten the plug or cap with an adjustable wrench.

d. Check that the hydraulic reservoir level is at least at the minimum operating level. If this level

is low, refer to para 8-13 and fill the reservoir as needed.

e. Operate all hydraulic subsystems (except those that may still be damaged) to remove air from the

system. Check carefully for fluid leaks. Tighten leaking fittings.

f. Check the hydraulic reservoir again to ensure a sufficient hydraulic fluid level. if this level is low,

refer to para 8-13 and fill the reservoir as needed.

g. Record the BDAR action taken. When the mission is Completed, as soon as practicable,

repair using standard maintenance procedures.

8-8.2. High-Pressure lube Isolation By Crimping Damaged End.

Limitations:

Not recommended for one-inch or larger tubes.
