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.

Maximum clearance for needle bearing or bushing is 0.0015 in. (0.0381 mm).
Transmissions with a serial number lower than 2510169200 may have a needle bearing;
serial numbers of 2510169200 and higher may have a bushing.
Needle bearing clearance is the inside diameter of output shaft needle bearing minus the
outside diameter of plain shaft bearing surface.
