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.
(2)
Inspect metal parts for breaks, cracks, burrs and sharp edges.
(3)
Inspect all bearings for wear, scoring and cracks.
(4)
Inspect split torque for broken splines and wear.
(5)
Inspect differential and bevel gear for broken splines and wear.
(6)
Inspect driven gear for broken splines and wear.
(7)
Inspect pinion shaft for broken splines and wear.
(8)

Assembly.
NOTE
Perform Steps (1) through (7) only if new pinion shaft and differential gear are being
installed.
The machined conical distance is engraved on pinion shaft head.
(1)
Record machined conical distance of used
pinion shaft (3) which was removed from
differential assembly.
(2)
Record machined conical distance of new
pinion shaft (3) which is to be installed in
the differential assembly.
(3)
Compare two distances recorded in Steps
(1) and (2). If distance recorded in Step (1)
is larger than distance recorded in Step (2),
