STEP 9
Torque bearing nut (16) 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 (13)
by torquing the nut (16) and then checking the rolling torque. Rotate hub (11)
by hand as nut is being tightened in order to seat bearings. N
lb.-ft. of torque may have to be applied to bearing nut (16) in order to press
cone (13) into position.
STEP 10
Remove bearing nut (16) and install lock washer (15). Replace bearing nut
(16).
STEP 11
Re-torque bearing nut (16) to 60 - 70 lb.-ft. (80 - 94 Nm).
STEP 12
Secure bearing nut (16) by bending a lock washer (15) tab into one of four
bearing nut slots. If no tab aligns with a slot, the nut may be tightened until
one of the slots aligns with a lock washer tab.
STEP 13
Assemble a washer (18), spring (19), a second washer (18), and a retaining
ring (17) in the middle grooves of input shaft (2). Install a second retaining ring
(17) in groove near small end of input shaft (2).
STEP 14
Assemble the splined end of the input shaft (2) closest to the disconnect
spring down into spindle (3).
STEP 15
Assemble the secondary carrier assembly (21) to spindle (3) at splines.
NOTE: When installing a hydraulic motor to the Power Wheel drive it is necessary to place an "O" ring or gasket (not supplied by Auburn Gear) between the
motor and the planetary drive. "O" ring sizes: SAE A 2-042, SAE B 2-155, SAE C 2-159.
It is recommended that the primary and secondary carrier assemblies (21 & 22) be serviced in their entirety to protect the integrity of the Power Wheel drive.
IMPORTANT: POWER WHEEL PLANETARY DRIVES ARE SHIPPED WITHOUT LUBRICANT AND MUST BE FILLED TO THE PROPER LEVEL PRIOR
TO START UP.
Observe lubrication recommendations given by the original equipment manufacturer. When specific recommendations are not available, use mild extreme
pressure lubricant API-GL-5, No. 80 or 90 when filling the Power Wheel under normal temperature ranges between 0 - 120°F (-18 to 49°C). Power Wheel is to
be half full of oil when unit is mounted level and horizontal. Use drain and fill plugs located in cover and ring gear. Oil is to be changed after first 50 hours of
operation with subsequent changes every 1000 hours or yearly, which ever comes first. If unit is to be operated vertically, if ambient conditions are outside the
specified range, or if the oil temperature exceeds 200°F (93°C) contact Auburn Gear for oil and level recommendations.
CAUTION: The Power Wheel will not normally be damaged by towing; however, the hydraulic drive components may be damaged unless the Power Wheel is
disengaged from the drive motor. Road speeds in excess of 25 MPH should be avoided unless clearly specified to be permissible by the equipment manufac-
turer.
CAUTION: For units equipped with the standard spring disconnect, assemble the disengage cover (31) with the dimpled center protruding inward. For units
equipped with the optional quick disconnect, push in center plunger of disconnect.
A protective film is applied to the Power Wheel at the factory to prevent rust during shipment. Additional protection may be required if the Power Wheel is to be
stored for an extended period of time.
Silastic RTV732 sealer and General Electric Silimate RTV No. 1473 or RTV No. 1503 are currently recommended for sealing gasket surfaces. Sealant should
be applied in a continuous bead, which should be centered on the surface to be sealed but should move to the inside of the hole at each bolt hole location. For
service requirements order Auburn Gear part number 604101.

STEP 16
Assemble the primary carrier assembly (22) into the ring gear (20). It will be
necessary to rotate carrier to align secondary sun gear {part of primary carrier
assembly (22)} with planet gear teeth in secondary carrier assembly (21).
Assemble primary sun gear (24) over input shaft (2). Rotate primary sun gear
: Up to 250
(24) to align input shaft (2) to gear splines and gear teeth in primary carrier
OTE
assembly (22).
STEP 17
Lubricate "O" ring (27) and assemble in groove inside cover hole, push
disengage plunger (26) into cover (28) with pointed end facing inside of unit.
STEP 18
Assemble the thrust washer (25) with tangs engaged with cover (28). N
small amount of grease applied to the back side of thrust washer (25) will hold
washer in place. Apply a bead of silicone sealant to end of face of ring gear
(20). Assemble cover (28) aligning holes of cover and ring gear. Assemble the
eight 5/16-18 x 1 inch hex head bolts (29). Torque bolts to 20 - 25 lb.-ft. (27 -
34 Nm).
STEP 19
Assemble the disengage cover (31) with dimpled center protruding out if
wheel is to be used to drive the vehicle. Assemble and torque the two 5/16-18
x 1/2 inch bolts (32). Torque bolts to 10 - 20 lb.-ft. (13 - 27 Nm).
STEP 20
Invert the Power Wheel assembly and assemble the coupling (1), with
counterbore out, to the input shaft (2).
STEP 21
After motor is assembled to drive or drive is sealed at spindle, fill with lubricant
to proper level and replace all plugs.
