ADJUSTMENTS
POWER STEERING PUMP BELT
Loosen nuts on pump mounting bracket. Turn adjuster bolt
until belt deflection is 3/8" (10 mm) at center of belt. Tighten nuts
to specification.
TESTING
HYDRAULIC SYSTEM PRESSURE TEST
1) Install Pressure Gauge (US1074 B) between pressure hose
and pressure line at valve housing. Open pressure gauge valve. Run
engine at idle. Turn steering wheel from lock to lock several times.
2) On Vanagon, pressure should be 1670-1750 psi (117-123
kg/cmý). On all others, pressure should be 1100-1200 psi (78-84
kg/cm
ý). If pressure is not within limits, see PUMP PRESSURE TEST.
3) If pump pressure is within specification, but system
pressure is low, replace steering gear.
PUMP PRESSURE TEST
1) Install Pressure Gauge (US1074 B) between pressure hose
and pressure line of valve housing. Start engine and let idle. Close
valve. Leave valve closed for no longer than 5 seconds. On Vanagon,
pressure should be 1670-1750 psi (117-123 kg/cm
ý). On all others,
pressure should be 1100-1200 psi (78-84 kg/cm
ý).
2) On all vehicles except Vanagon, go to step 3). On Vanagon,
if pressure is not to specification, inspect limiting valve and
housing bores and piston for obstructions. Ensure piston moves freely
in housing. Install new valve if necessary.

If steering effort is too high, check steering shaft,
steering linkage, "U" joints, and ball joints for binding. If all are
okay, replace steering gear.
REMOVAL & INSTALLATION
POWER STEERING PUMP
Removal
Remove alternator and pump belts. Disconnect hydraulic lines
from pump. Cap lines to prevent contamination. Remove bracket bolts.
