Assembly of drive pinion bearing
①
Insert the two outer rings of the taper
roller bearings into the differential carrier.
②
Calculate the thickness C of the spacer
ring.
a.
Place the two inner rings of the taper
roller bearings in their outer rings.
Measure A.
b.
Measure the dimension B of the drive
pinion.
c.
Thickness of the spacer ring C = A-B.
③
Heat the drive pinion side taper roller
bearing to about
100。 C and install it on
the drive pinion shaft.(Drive on complete-
ly after it cools)
④
Install the spacer ring on the pinion shaft.
⑤
Install the drive pinion into the differential
carrier. Heat the taper roller bearing
inner ring at undersize to about
and install it with a tube onto the drive
pinion shaft.
⑥
Install the drive flange onto the drive
pinion shaft. Tighten the safety nut
according page 3-119. For tightening fix
the differential carrier and block the drive
flange.
⑦
Measure the resistance of the bearings by using a torque wrench. If the measured value is not
the prescribed 0.8 to 1.2Nm, adjust the resistance by modification of the thickness of the spacer
ring. After arriving at the adjustment of the bearing, back-off the safety nut and draw off the drive
flange.
⑧
Install the radial seal ring with Loctite 572 applied. Fill the radial seal ring with bearing grease.
Fit the carrier of the parking brake(if present) on the differential carrier and tighten the screws.
Slip on the drive flange, screw on the safety nut with sealing compound between the contact
surfaces. Tighten the safety nut according page 3-119. Lock the nut by striking the nut brim into
the slot of the pinon.
