9. Torque bearing nut (16) with Bearing Locknut
Tool (Service Kit #100254-020) 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 press-
ing 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.
NOTE: Up to 250 lb.-ft. of torque may have to be
applied to bearing nut (16) in order to press
cone (13) into position.
10. Remove bearing nut (16) and install lock washer
(15). Replace bearing nut (16).
11. Re-torque bearing nut (16) to 80-90 Nm-ft (60-70
lb.)
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 tight-
ened until one of the slots aligns with a lock
washer tab.
13. Assemble a washer (18), spring (19), a second
washer (18), and a retaining ring (17) in the mid-
dle grooves of input shaft (2). Install a second
retaining ring (17) in groove near small end of
input shaft (2).
14. Assemble the splined end of the input shaft (2)
down into spindle (3).
15. Assemble the secondary carrier assembly (21) to
spindle (3) at splines.
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 pri-
mary carrier assembly (22)) with planet gear
teeth in secondary carrier assembly (21). Assem-
ble primary sun gear (24) over input shaft (2).
Rotate primary sun gear (24) to align input shaft
(2) to gear splines and gear teeth in primary car-
rier assembly (22).
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.
18. Assemble the thrust washer (25) with tangs
engaged with cover (28). NOTE: A 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
27-34 Nm (20-25 lb.-ft.).
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
13-27 Nm (10-20 lb.-ft.).
20. Invert the torque hub assembly and assemble the
coupling (1), with counterbore out, to the input
shaft (2).
21. After motor is assembled to drive or drive is
sealed at spindle, fill with lubricant to proper level
and replace all plugs.
Carrier Assemblies
Do not attempt to service primary or secondary car-
rier assemblies.
Sealing Compound
Silastic RTV732 sealer and General Electric Silimate
RTV No. 1473 or RTV No. 1503 are currently recom-
mended 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 loca-
tion.
