STEP 2

Position the assembly upright on face of spindle (3).

STEP 3

Remove the disengage cover (31) if necessary.

STEP 4

Remove eight bolts (29) and the large cover (28) from the unit. The thrust

washer (25) and the disengage plunger (26) usually remain attached to the

STEP 1

Press new bearing cups (7 & 12) in each side of the hub (11). It is recom-

mended that bearing cups (7 & 12) and cones (6 & 13) be replaced in sets.

STEP 2

Assemble bearing cone (6) into cup (7) at seal end of hub (11) and press a

new seal (5) into hub (11). Install boot seal (4) on hub (11) if unit is so

equipped.

STEP 3

Position spindle (3) upright on bench. Lubricate lips of seal (5) and lower hub

(11) onto spindle (3). Hub (11) should be centered as it is lowered over spindle

(3) to prevent seal damage.

STEP 4

Assemble bearing cone (13) over spindle (3). Press bearing cone (13) over

spindle bearing journal using press and cylindrical bearing cone driver 598E.

Press bearing cone (13) down until rollers just touch cup (12). Take care to

avoid pressing cone (13) too far. N

598E over splined end of spindle (3) on the edge of bearing cone (13) and

DISASSEMBLY OF POWER WHEEL

ASSEMBLY OF POWER WHEEL

: If a press is not available, place tool

OTE

STEP 9

One tab of lock washer (15) will be engaged in slot of bearing nut (16); bend

back to release. Remove the bearing nut (16), lock washer (15) and thrust

washer (14). 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 10

Bolt spindle drive tool, 598FF, to ring gear (20). Grade 8 bolts should be used.

Drive spindle (3) from hub (11) by turning center bolt of spindle drive tool.

Care should be taken to avoid damaging splines and threads on spindle.

: Bearing cone (13) has been designed with a press fit with respect to

OTE

spindle (3). Considerable force will be required to remove cone from spindle.

STEP 11

Remove spindle drive tool from ring gear (20).

STEP 12

Remove the 12 bolts (9) and washers (10) from hub (11) and remove ring

gear (20). It may be necessary to strike ring gear (20) with a rubber mallet to

loosen from hub (11).

STEP 13

Remove the boot seal (4) and oil seal (5) and bearing cones (6 & 13) from

hub (11). Inspect bearing cups (7 & 12) in position and remove only if

replacement is required.

STEP 5

Install thrust washer (14) with tab in keyway of spindle and bearing nut (16).

DO NOT install lock washer (15) at this time.

STEP 6

Clean mating surfaces and apply a bead of silicone sealant to face of hub (11)

that mates with ring gear (20). See instructions on sealant package. Hub (11)

is attached to ring gear (20) with 12 3/8-24 grade 8 hex head cap screws (9)

and flat washers (10). Torque cap screws to 52 - 60 lb.-ft. (70 - 81 Nm).

STEP 7

Place spindle drive tool, 598FF, over spindle (3) and bolt or pin to ring gear

(20). 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 drive tool and turning hub (11) slowly and

steadily with the torque wrench. Note mean torque. An initial bearing torque of

greater than 52 lb.-in. with boot seal installed or 46 lb.-in. without boot seal

means that the cone (13) was pressed on too tightly in step 4. In this case,

back off bearing cone (13) by pressing spindle (3) out of cone (13) until initial

preload is relieved. See step 10 of disassembly procedure.
