SSEMBLY
(See Figure 7.)
1.
Assemble the steerable struts as follows:
NOTE:
Assembly of the left- and right-hand
steerable struts are identical.
a.
Install the strut weldment pivot (21) to the pivot
weldment (20) and secure with ball bearing, thrust
(18), kingpin (17), 1/2 X 6 HHCS (24), and 1/2
lock nuts (25).
NOTE:
Pre-pack the bearing with grease.
b.
Install 3-1/2 X 8 standard hydraulic cylinders (3)
to provide turning for each strut.
NOTE:
The stop nuts on the cylinder rods must
be removed and installed on the other cylinders
to raise.
c.
Install the axle assembly (22) with spindles and
hubs into upright tubes on each strut assembly.
d.
Install the 3-3/4 X 8 series hydraulic cylinder (13)
and the 3-1/2 X 8 series hydraulic cylinder (12) to
provide height adjustment.
NOTE:
The stop nuts on rods of other cylinders are
used on these cylinders. These cylinders must be
plumbed as shown.
NOTE:
The cylinders re-phase when fully extended.
2.
Install the steerable carrier struts so the tires will
straddle the third row in on each side. This is 154
inches center-line to center-line. Secure using L-
Bolts (3/4 dia. X 6-7/8 X 8-3/4), flat-washers, lock-
washers, and nuts (4, 5, 6, 7).
3.
Install wheel and tire assemblies in ground drive
position making sure the tire spacing is 22 inches
center-line to center-line.
4.
Assemble the ball joints (LH – 28 and RH – 29)
into the appropriate end of the short tie rod (34) ,
use appropriate 1 inch nut (LH – 35 or RH – 36)
prior to installing into short tie rod. Make sure each
is equal distance to the nut.
5.
Install these assemblies into center tie rod (30)
using 1/2 X 3-1/4 HHCS and lock nut (33, 10).
6.
Install this assembly onto the struts using 3/4 X 3-
1/4 HHCS and lock-nut (32, 33). Adjust the tie rod
so tires are parallel.
7.
Install indicator rod (19) onto strut arm as shown
using 3/4 X 2-1/2 HHCS, lock-washer, and nut (23,
6, 7)
8.
Install hydraulic plumbing for the steering and lift
circuits as shown.
NOTE:
The lift circuit uses series cylinders. The
tractor lines must go to the base end of the 3.75
(larger) and to the rod end of the 3.5 (smaller). To fill
these with oil; raise and hold hydraulics.
NOTE:
The cylinders re-phase when fully extended.
9.
Secure the hoses with the hose clamps (37) and
bar holder (38) using 3/8 X 3 carriage bolt and
lock-nut (50, 51). Route and clamp to tractor.
