Repair of Piston Rod Damage to Prevent Rod Seal Destruction (Using File).

TM 5-3835-222-BD

j. 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.

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

using standard maintenance procedures.

8-12.2 Repair of Piston Rod Damage to Prevent Rod Seal Destruction (Using File).

Limitation:

Cylinder rod seals will not seal over damaged portion of rod, resulting in some leakage.

Dirt may be carried into cylinder in damaged rod section, resulting in fluid damage.

Rod may be weakened due to damage.

Personnel/Time Required:

1 soldier 30 minutes

Materials/Tools:

Sharpening Stone

Tool Kit

Procedural Steps:

a. File down sharp edges at damaged point to original rod diameter.

b. Rub repaired area with cloth to check for snags and sharp points,

c. Repeat steps 1 and 2 until no snags occur.

d. Wash metal filings from rod using hydraulic fluid.

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 level. 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 as soon as practicable,

repair using standard maintenance procedures.
