torque wrench, assemble pinion cage into the carrier
housing and install two mounting bolts to anchor
the unit.
Rotate pinion with the torque wrench. See F See F See F See F See Figur igur igur igur igure 8 e 8 e 8 e 8 e 8.
Torque measurement will be taken during fourth revolu-
tion and must be between 10-40 Lb-in (1.1-4.5 N-m)
without pinion seal.
