If necessary, remove bearing assembly (12) and seal
(13) from shaft assembly (7).
Seal (13) will be damaged and will require
replacement if removed.
The following steps are for the assembly of the
drum support housing.
Install two bearing races (11) into housing (8) with a
press or a hammer and a brass drift.
Install bearing assembly (12) into housing (8) with the
hub flange upright.
The bearing assembly should be clean and wiped
dry of any lubricating oil. Bearing assemblies
which have oil present will affect rolling torque
Apply a light lubricating oil to the lip of seal (13)
and press into housing (8) with a press.
Apply grease to seal (9) and install seal into housing (8).
Press shaft assembly (7) into seal (9) and bearing
Turn the housing 180 and secure shaft assembly so it
will not move during the next procedure.
Place a bolt into the housing to rotate the housing with a
torque wrench. Use a torque wrench capable of inch-
lbs to determine the rolling torque created. A typical
rolling torque value is 3.4 N· m (30 lb-in).
Heat bearing (10) to 135° C (275° F). Press in bearing
assembly (10) until the rolling torque increases 1.7 to
4.5 N· m (15 to 40 lb-in) greater than the value
measured in Step 22.
It will be necessary to continually rotate the
housing to seat the bearing assembly in order to
obtain a correct rolling resistance.
Install flat washer (6).
Install tab washer (5).
Use Tool (A) to install retaining nut (4).
Apply 9S-3263 Thread Lock to the threads of nut
Use Tool (A) and tighten retaining nut (4) to a torque of
306 N·m (225 lb-ft).
Recheck the rolling torque. The final reading should be
1.7 to 4.5 N· m (15 to 40 lb-in) greater than the value
observed in Step 22.
A final rolling torque of 5 to 7 N· m (45 to 65 lb-in)
should result in a bearing preload of .0254 to
.0508 mm (.001 to .002 in).
Bend tab washer (5) up into slot on retaining nut (4).
If the tang does not line up, tighten nut (4) until
the tang can be bent into the slot.
Release shaft assembly and remove bolt used for
checking rolling torque.
For the drum support housing on the right hand side
(CS-431C, CP-433C & CS-433C), install O-ring (3). For
the drum support housing on the left hand side (CS-
431C only), apply a 3.2 mm (.125 in) continuous bead
of 8T-9014 Silicone Sealant on the mounting surface of
the housing where the cover fastens.
Position cover (2) in its original location.
Install twelve bolts (1). Place longer bolts and washers
in their original locations.
