For Tubes Only: In most cases, it will be desirable to replace a damaged hydraulic tube with a

hydraulic hose, due to the unique configuration of hydraulic tubes. Similar tubes, carefully bent

so as not to crimp the tube, may be cannibalized to replace a damaged hydraulic tube or hose. If

fitting types are identical, any compatible metal hydraulic tube (high- or low-pressure) may be used to

replace any hydraulic tube (high- or low-pressure).

c. Check that the cannibalized line is long enough to replace the damaged line.

d. Using adjustable wrenches, remove both lines and replace the damaged line with the cannibalized

line. Take extra caution that the line fittings are properly threaded. Tighten these fittings snugly.

e. Check that the hydraulic reservoir is at least 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 level again to ensure a sufficient hydraulic fluid level. If this level

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

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

using standard maintenance procedures.

8-5. Hose Repair. The following options explain how to repair damaged hydraulic hoses. Use one

of the following options to repair a damaged hydraulic hose. Damaged high-pressure hoses require

a high-pressure fix. Damaged low-pressure hoses may be repaired by either a high- or low-pressure

fix; however, high-pressure fixes are preferred.

8-5.1 High-Pressure Hose Fabrication.

Limitations:

High-pressure hose must be used for high-pressure repairs.

Personnel/Time Required:

1 soldier - 1.5 hrs.

Materials/Tools:

Tool Kit

Hose Fittings

Hose, Hydraulic, High-Pressure

Tape

Saw

Vise
