DISASSEMBLY OF POWER WHEEL
STEP 1
Remove twenty-four hex head bolts (20) and washers (19) from cover
(17). Thrust washer (16) usually remains with cover.
STEP 2
Lift sun gear (15) from primary carrier assembly (14).
STEP 3
Remove primary carrier assembly (14) from ring gear (7).
STEP 4
Remove ring gear (7) from hub (6). It may be necessary to
strike ring gear (7) with a rubber mallet to loosen from hub (6).
STEP 5
Remove the secondary carrier assembly (13).
STEP 6
One tab of lock washer (11) will be engaged in slot of bearing nut (12);
bend tab back to release. Remove the bearing nut (12), lock washer
(11) and thrust washer (10). NOTE:
A special locknut wrench,
AG21308, is required for the removal of the bearing locknut. Contact
Auburn Gear to purchase wrench and other service tools. Drawings
are also attached.
STEP 7
Place assembly in press with output shaft or spindle (1) down on hub
flange (6). Place material under output shaft or spindle so not to
damage when it’s pressed out of hub. Care should be taken to avoid
damaging splines and threads on output shaft or spindle while pressing
it out. NOTE
:
Bearing cone (8) has been designed with a press fit with
respect to output shaft or spindle (1). Considerable force will be
required to remove cone from output shaft or spindle.
If a press is not available you will need the AGXXXXX(Contact Auburn
Gear) Spindle/Shaft removal tool. Place the small disk on the end of
the spindle/shaft. Mount the cross tube to the hub. Turn the screw
against the small disk, DO NOT use an impact gun. Turning the screw
will force the spindle/shaft out of the bearing cone.
STEP 8
Remove the oil seal (3) & boot seal (2), if included and bearing cones
(4 & 8) from hub (6). Inspect bearing cups (5 & 9) in position and
remove only if replacement is required.
ASSEMBLY OF POWER WHEEL
STEP 1
Press new bearing cups (5 & 9) in each side of the hub (6). It is
recommended that bearing cups (5 & 9) and cones (4 & 8) be
replaced in sets.
STEP 2
Assemble bearing cone (4) into cup (5) at seal end of hub (6) and
press a new seal (3) into hub (6). Install boot seal (2) on hub (6) if
unit is so equipped.
STEP 3
Position output shaft or spindle (1) upright on bench. Lubricate lips
of seals (2) and (3), seal surface of output shaft or spindle, and
lower hub (6) onto output shaft or spindle (1). Hub (6) should be
centered as it is lowered over output shaft or spindle (1) to prevent
seal damage.
NOTE: On heavy duty seals (order code T) there is to
be no lubricant on seal (3), output shaft or spindle (1),
or hub (6).
STEP 4
Press inner bearing cone (8) onto shaft (1) until rollers just contact
inner bearing cup (9) using a cylinder that is in full contact with the
ID of the bearing cone (see photo below).
STEP 5
Install tab of thrust washer (10) into slot of output shaft or spindle
(1). Place lock washer (11) onto output shaft or spindle (1).
STEP 6
Torque bearing nut (12) to 50 lb ft using tool AG21308.
STEP 7
Rotate hub several revolutions in each direction to allow bearings to
seat.
STEP 8
Using an appropriate pick, check each roller of the inner bearing
cone (8) for looseness.
STEP 9
If all rollers are tight, proceed to step 12.
STEP 10
With bearing nut tool AG21308 placed on bearing nut (12), tap end
of bearing nut tool with an appropriate hammer to advance the inner
bearing cone (8) further onto shaft (1).
STEP 11
Repeat steps 7 thru 10 until all inner bearing cone rollers are tight.
