+Install pipe connector.
+Observe specified tightening torque when tightening high-pres-
sure and low-pressure pipe connectors. Excessive tightening
will damage threads of connector or O-ring.
Connector tightening torque:
1 Low-pressure side
27 - 39 N´m (2.8 - 4.0 kg-m, 20 - 29 ft-lb)
2 High-pressure side
15 - 25 N´m (1.5 - 2.5 kg-m, 11 - 18 ft-lb)
+The O-ring in low-pressure pipe connector is larger than that
in high-pressure connector. Take care to install the proper
O-ring.
SST824A
+Initially, tighten nut on tie-rod outer socket and knuckle arm to
29 to 39 N´m (3 to 4 kg-m, 22 to 29 ft-lb). Then tighten further
to align nut groove with first pin hole so that cotter pin can be
installed.
CAUTION:
Tightening torque must not exceed 49 N´m (5 kg-m, 36 ft-lb).
NOTE:
Only the dust boot, tie-rod inner socket and tie-rod outer socket can
be disassembled on models for Europe.
SST819A
+Before removing lower joint from gear, set gear in neutral
(wheels in straight-ahead position). After removing lower joint,
put matching mark on pinion shaft and pinion housing to record
neutral position.
+To install, set left and right dust boots to equal deflection.
Attach lower joint by aligning matching marks of pinion shaft
and pinion housing.
+Tighten gear housing mounting bracket bolts.
SST862CB
DisassemblyNJST00231. Prior to disassembling, measure pinion rotating torque. Record
the pinion rotating torque as a reference.
+Before measuring, disconnect gear housing tube and
drain fluid.
+Use soft jaws when holding steering gear housing. Handle
gear housing carefully, as it is made of aluminum. Do not
grip cylinder in a vise.
2. Remove gear sub-assembly, O-ring and shim.
Gear sub-assembly cannot be disassembled. If it is faulty,
replace with a new one.
