Pinion Bearing: Service and Repair
Dana/Spicer Front Axle
Bearing Cup & Drive Pinion Installation
1.
Clean bore and if installed, remove the cup. Place oil baffle first and the required amount of shims in the inner pinion bearing bore and drive inner
pinion bearing cup in place.
2.
Place outer pinion cup into carrier and drive in place. Draw cups into the bore.
3.
Lubricate ends of outer pinion bearings rollers. Install outer bearing cone into place on the outer bearing cup.
4.
Install inner bearing cone and slinger onto pinion. Drive bearing on the pinion shaft until fully seated.
Drive Pinion Preload Check & Final Depth Check
1.
Measure original preload shims and replace with new shims of equal size.
2.
Install pinion into carrier.
3.
Install new preload shims over pinion. Install outer pinion bearing cone and oil slinger. Assemble end yoke, washer, deflector and slinger onto
pinion shaft and align assembly. Install a new pinion nut and torque to 200---220 ft. lbs. on except model 60 monobeam type axle or 240-300 ft.
lbs. on model 60 monobeam axle.
4.
Rotate pinion nut with an inch-pound torque wrench. Rotating torque should be 20---40 inch lbs. on except model 28 axle or 10 inch lbs. on model
28 axle. To increase preload, remove shims. To decrease preload, add shims.
5.
Install bearing caps and torque to 80---90 ft. lbs. on except model 28 axle or 35---40 ft. lbs. on model 28 axle.
6.
Install suitable final check gauge block onto top of the pinion button under the gauge tube. Place thumb on the gauge block to ensure block is
level.
7.
Insert feeler gauges between gauge tube and final check gauge block until a slight drag is felt.
8.
On except model 28 axles, the reading should be .020 inch added to the drive pinion etching, which could be plus (+) or minus (-) - ) with a
tolerance of .002 inch. On model 28 axles (for example), if original pinion is etched (+) 4 (m + 10), and the new pinion is etched ``0'', then a new
selective slinger is .004 inch thicker than the original selective oil slinger. If the original pinion is ``0'' and the new pinion is etched (+) 3 (m + 8),
the new selective slinger should be .003 inch thinner than the original slinger.
9.
With drive pinion at the correct depth, remove yoke, washer and nut.
10.
Coat oil seal with suitable lubricant. Install drive pinion oil seal. After installation, ensure garter spring did not pop out. If garter spring pops out,
remove and replace seal.
11.
Install yoke. Install washer and nut. Tighten nut to 200---220 ft. lbs. on except model 60 monobeam axle or 240-300 ft. lbs on monobeam type
axle.
