Assembly.
ROLLING RESISTANCE OF DRIVE PINION BEARING.
The rolling resistance of the drive pinion bearing without
the seal on the shaft is approximately 0.6 to 0.9 lbs-ft (0.8
to 1.2 Nm) as measured by a torque wrench.
TIGHTENING TORQUE OF THE ADJUSTING NUT ON
THE DRIVE FLANGE.
For the proper torque on the castle nut or adjusting nut on
the drive flange, refer to the values on the following table.

DRIVE GEAR TEETH EDGE CLEARANCES.
The bevel gear drive gear teeth edge clearances should be
approximately 0.011 to 0.015 in. (0.3 to 0.4 mm)
(approximate minimum value 1/1,000th of the diameter of
the ring gear).
