3. Press the wheel tube, sleeve and bearings as assembled into the jacket tube (8) end that has the
counter bore and internal retaining ring groove until the upper bearing (3) is beyond the retain-
ing ring groove. A tubular bearing installer tool pressing against the upper bearing (3) outer race
is required. The split in the bearing spacer (12) must be aligned with the screw hole in the top
end of jacket tube to allow later assembly of bolt (43). Assemble retaining rings (9 & 15) in their
grooves on jacket tube.
4. To assemble the wheel tube and jacket tube assembly into the main housing assembly (18), place
jacket tube end down on a pedestal about 4 inches (101.6 mm) high x 2-114 inches (57.2 mm)
diameter. Be sure cutouts of lower collet in main housing assembly (18) align with holes for lock
pin (29) and stop screw (23). Be sure ends of the spring in the housing are approximately 90
degrees from the splits in the collets. This will facilitate assembly of jacket tube in housing. As-
semble the main housing down over the jacket tube such that jacket tube will enter the housing
bore lower collet. As the upper end of the jacket approaches the upper tapered collet, the collet
must be pushed down with a screwdriver or a suitable tool that will pilot over the wheel tube and
into the housing bore. This will allow the jacket tube assembly to be pushed through the upper
collets.
5. Align the jacket tube guide slot with the stop screw hole in the main housing assembly (18) and
torque button head stop screw (23) and internal tooth lock washer (24) into stop screw hole to
15-20 ft-lb (20.3–27.1 N-m).
6. Press in a new bearing (3) into each counter bore in lower
bearing housing (2) if the bearings were removed.
7. Assemble the lower serrated shaft of universal joint assembly (6) into lower bearing housing as-
sembly (2) until it is seated against a bearing (3). Assemble retaining ring (1) onto universal joint
shaft. Turn 1/8 inch pipe plug (14) finger tight into tapped hole in slotted end of u-joint shaft.
Assemble spring retaining rod (5) into bearing housing (2).
If pipe plug is tightened such that the end of U-joint shaft is spread open,
the shaft may not assemble into spline sleeve as required.
8. Place the main housing assembly (18) as assembled, vertical in a soft-jawed vise, clamping
firmly against the serrated end of wheel tube assembly (10). As an alternative the steering wheel
can be set on the wheel tube as a holding fixture and the unit set upside down on a bench for
these procedures. Push the wheel tube and jacket to full-down position in the main housing. As-
semble spring (7) over lower end of wheel tube and splined sleeve assembly. Assemble universal
joint (6) splined shaft into the spring (7) and into splined sleeve so that a slot in the splined shaft
aligns with the wide flute in the mating splined sleeve. Two fingers in the lower u-joint shaft
yoke will help guide the shaft into the splined sleeve. Push the universal joint assembly and
lower housing (2) into the main housing (18) assembly and align the screw holes in the support
bracket (17) with the holes in lower housing.
