STEP 1

Remove eight hex head bolts (21) from cover (20). Lift cover (20) from

assembly. Thrust washer (19) usually remains with cover (20).

STEP 2

Lift sun gear (18) from primary carrier assembly (17).

STEP 3

Remove primary carrier assembly (17).

STEP 4

Remove the secondary carrier assembly (16)

STEP 5

One tab of lock washer (13) will be engaged in slot of bearing nut (14); bend

back to release. Remove the bearing nut (14), lock washer (13) and thrust

washer (12). N

: A special locknut wrench, 596Z, is required for the removal

OTE

of the bearing locknut. Contact Auburn Gear for procurement of wrench and

other service tools.

STEP 1

Press new bearing cups (5 & 10) into each side of hub (9). It is

recommended that bearing cups (5 & 10) and cones (4 & 11) be

replaced in sets.

STEP 2

Assemble bearing cone (4) into cup (5) at seal end of hub (9) and

press a new seal (3) into hub (9).

STEP 3

Lubricate lips of oil seal (3) and boot seal (2) if unit is so equipped and

lower hub (9) onto output shaft (1). Keep hub (9) centered to prevent

damage to oil seal (3).

STEP 4

Assemble bearing cone (11) over output shaft (1). Press bearing cone

(11) over output shaft bearing journal using press and cylindrical

bearing cone driver 598E. Press bearing cone (11) down until rollers

just touch cup (10). Take care to avoid pressing cone (11) too far.

: If a press is not available, place tool 598E over splined end of

OTE

output shaft (1) on the edge of bearing cone (11) and drive into place

with hammer or mallet. If this method is used, care must be taken to

avoid damage to bearing cone and spindle.

STEP 5

Install thrust washer (12) and bearing nut (14). DO NOT install lock

washer (13) at this time.

STEP 6

Clean mating surfaces and apply a bead of silicone sealant to face of hub (9)

that mates with ring gear (15). See instructions on sealant package. Hub (9) is

attached to ring gear (15) with 12 3/8-24 grade 8 hex head cap screws (6)

and flat washers (7). Torque cap screws to 52 - 60 lb.-ft. (70 - 81 Nm).

ASSEMBLY OF POWER WHEEL

STEP 6

Bolt spindle drive tool, 598FF, to ring gear (15). Grade 8 bolts should be used.

Drive shaft (1) from hub (9) by turning center bolt of spindle drive tool. Care

should be taken to avoid damaging splines and threads on shaft. N

Bearing cone (11) has been designed with a press fit with respect to shaft (1).

Considerable force will be required to remove cone from shaft.

STEP 7

Remove spindle drive tool from ring gear (15).

STEP 8

Remove the 12 bolts (6) and flat washers (7) from hub (9) and remove ring

gear (15). It may be necessary to strike ring gear (15) with a rubber mallet to

loosen from hub (9).

STEP 9

Remove boot seal (2) if included, oil seal (3) and bearing cones (4 & 11)

from hub (9). Inspect bearing cups (5 & 10) in hub (9) and remove only

if replacement is required.

STEP 7

Place spindle drive tool, 598FF, over shaft (1) and bolt or pin to ring gear (15).

Make sure center bolt of drive tool is not touching spindle and is prevented

from rotating by jam nuts provided on tool.

STEP 8

Check initial rolling torque by installing a lb.-in. torque wrench (arm or

dial type) on center nut of spindle/shaft drive tool and turning hub (9)

slowly and steadily with the torque wrench. Note mean torque. An

initial bearing rolling torque of greater than 52 lb.-in. with boot seal

installed or 48 lb.-in. without boot seal means that the cone (11) was

pressed on too tightly in step 4. In this case, back off bearing cone

(11) by pressing output shaft (1) out of cone (11) until initial preload is

relieved. See step 6 of disassembly procedure.

STEP 9

Torque bearing nut (14) with bearing nut wrench 596Z until a bearing

rolling torque of 42 - 50 lb.-in., with a boot seal installed, or 38 - 46 lb.-

in., without a boot seal, is reached. This may require several trials of

pressing the cone (11) by torquing the nut (14) and then checking the

rolling torque. Rotate hub (9) by hand as nut is being tightened in

order to seat bearings. N

OTE

be applied to bearing nut (14) in order to press cone (11) into position.

STEP 10

Remove bearing nut (14) and install lock washer (13). Replace

bearing nut (14).

STEP 11

Re-torque bearing nut (14) to 60 - 70 lb.-ft. (80 - 94 Nm).

: Up to 250 lb.-ft. of torque may have to
