a.
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.
NOTE
All eight cylinder liners are cleaned, inspected, and repaired the same way.
(1)
Clean all parts with drycleaning solvent.
(2)
Inspect cylinder liner for cracks and scoring. A slightly scored cylinder liner may be honed and reused.
If cracked or excessively scored, replace cylinder liner.
(3)
Inspect cylinder liner area above port holes for pitting. If pitting is noted, replace cylinder liner.
(4)
Inspect inside surface of cylinder liner at top for ridge. If ridge is not excessive it may be honed.
