INSPECT TRACK TENSIONING RELIEF VALVE.
a.
Visually inspect valve body (28), surfaces A, for
stripped threads. Use a strong light and
inspect inner bores B for foreign material.
Cleaning solvent, P-D-680, is TOXIC
and
flammable.
Wear
protective
goggles and gloves. Use only in a well
ventilated area. Avoid contact with skin,
eyes, and clothes, and do not breathe
vapors. Keep away from heat or flame.
Never smoke when using solvent; the
flashpoint for Type m cleaning solvent is
200°F (93,30C). Failure to do so may
result in injury or death to personnel.
If personnel become dizzy while using
cleaning solvent, immediately get fresh
air and medical help. If solvent contacts
skin or clothes, flush with cold water. If
solvent contacts eyes, flush eyes with
water and get immediate medical
attention.
b.
Flush valve body (28) with cleaning solvent to
remove any foreign material present. Use a
culture swab to remove foreign material from
valve body inner bore. If foreign material
cannot be removed, replace valve body.
c.
Replace valve body (28) if threads are stripped.
d.
Inspect spring (25) for distortion. Replace
spring if distortion is detected.
e.
Inspect check ball (26) and valve seat (27) for
nicks, dents, or excessive wear. Replace
check ball and valve seat if damaged.
