Cleaning/Inspection.
Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face
shield, 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 II Drycleaning Solvent is 140 degrees F (60 degrees
C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). 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, immediately flush eyes with water and get immediate medical attention.
(1)
Clean all metal parts with drycleaning solvent P-D-680.
Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Use only with
effective chip guarding and personal protective equipment (goggles/shield, gloves, etc).
Failure to comply may result in injury or death to personnel.
(2)
Dry all parts, except for bearings, with compressed air.
Keep bearings clean. The presence of dirt or grit on bearing rollers/balls is usually responsible
for bearing failures, it is important to keep bearings clean during removal, inspection, and
installation. To make sure maximum bearing life, do not remove wrapper from new or clean
used bearings until ready to install them. Do not remove grease in which bearings are packed.
Do not lay bearings on a dirty bench; place them on a clean lint-free paper.
(3)
Inspect bearings for roughness of rotation. Replace bearing if its rotation is still rough after cleaning and
oiling.
(4)
Inspect torque converter turbine for cracks, gouges, wear or binding. Replace torque converter turbine if
damaged.
(5)
Inspect lockup clutch plate for uneven wear or signs of overheating. Replace if damaged.
