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.
Keep bearings clean. 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. Do not remove grease in which bearings are packed. Do not
lay bearings on dirty bench; place on clean lint-free paper. If assembly is not to be
completed at once, wrap or cover exposed bearings with clean paper or lint-free cloth to
keep out dust.
(1)
Clean all parts using drycleaning solvent.
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 bearing, with compressed air. Allow bearing to air dry.
(3)
Inspect all parts for nicks, scratches or burrs. Replace all damaged parts.
(4)
Coat all parts and bearing with clean hydraulic oil.
If bearing or any one race is being replaced, replace both bearing races and bearing as a set or
damage to parts may occur.
(5)
Inspect bearings for roughness of rotation. Replace bearing if rotation is still rough after cleaning and
oiling.
