Table U: Drive Pinion Bearings — Preload (See to Section 5)
MAINTENANCE MANUAL
Specifications Adjustments
Specification New bearings
5-45 lb-in (0.56-5.08 N.m)
Used bearings in good condition
10-30 lb-in (1.13-3.39 N.m)
Adjustment Preload is controlled by the thickness of the spacer
between bearing cones.
To increase preload, install a thinner spacer.
To decrease preload, install a thicker spacer
Tabela V: Drive Pinion — Depth in Differentia (See to Section 5)
Specification Install the correct amount of shims between the inner
bearing cap of the drive pinion and the differential. To
calculate, use the old shim pack thickness and the new
and old pinion cone numbers.
Adjustment Change the thickness of the shim pack to get a good
gear tooth contact pattern
Table W: Hypoid Gear Set — Tooth Contact Patterns (Hand Rolled) (See to Section 5)
Specification Toward the toe of the gear tooth and in the center between
the top and bottom of the tooth.
Adjustment Tooth contact patterns are controlled by the thickness
of the shim pack between the inner bearing cone of the
drive pinion and the differential and by ring gear backlash.
To move the contact pattern lower, increase the thickness
of the shim pack between the inner bearing cup of the
drive pinion and the differential.
To move the contact pattern higher, decrease the thickness
of the shim pack between the inner bearing cup of
the drive pinion and the differential.
To move the contact pattern toward the toe of the tooth,
decrease backlash of the ring gear.
To move the contact pattern toward the heel of the tooth,
increase backlash of the ring gear.
Table X: Main Differential Bearings — Preload (See to Section 5)
Specification 15-35lb-in (1.7-3.9N m)
orExpansion between bearing caps
140 and 145 Series — 0.003-0.009-inch (0.08-0.22mm)
160 Series — 0.006-0.013-inch (0.15-0.33mm)
Adjustment Preload is controlled by tightening both adjusting rings
after zero end play is reached.
Table Y: Main Differential Gears — Rotating Resistance (See to Section 5)
Specification 68 N.m (50 lb-ft) Torque máximo verificado para girar un
planetario
