ACTION
REMARKS
When setting poppets, do not hold steering in full lock position for
more than 15 seconds. If full lock position Is held for more than 15
seconds, excessive heat will build up in system and extensive dam-
age may occur.
NOTE
Poppet adjusting screws are adjusted to relieve pressure at 32 degree
steering angle. Make sure 1/8-inch (3mm) spacer is between steering
knuckle stop screw and axle beam boss when adjusting poppet adjusting
screws.
NOTE
The power steering pump has an internal system relief valve to limit maxi-
mum pump pressure to 1850-2050 psi (12756-14135 kPa). Observed
operating pressure is variable and dependent on the resistance within the
steering system (e.g. tire inflation, floor surface). Typically, system pres-
sure will be approximately 1100-1500 psi (7585-10343 kPa) with properly
inflated tires on concrete floor.

Pressure should be above
900 psi (6205 kPa) until
the steering stop contacts
the l/8-inch spacer and
steering stop boss, then
drops to 400-900 psi
