4. Install the valve spring and valve retainer. then
install the valve spring compressor. Compress the
spring and installthe valve keepers.
NOTE: Place the end of the valve spring with close-
ly wound coils toward the cylinder head.
lCornmercially available)Snap-on CFrll or KD - 3tX'with #32 JAWS
Lightly tap the end of each valve stem two or three
times with a plastic mallet to ensure proper seating
of the valve and valve keepers.
NOTE: Tap the valve stem only along its axis so you
do not bend the stem.

Installation
CAUTION:
. Make sure that all tockers are in alignment with their
valvgs when torquing the rocket assembly bolts,. Valve locknuls should be loosened and adiusting
screws backed off bofore installation.
. To prevont tho rocker arm a$smbly from coming
apad, l6av€ the camshaft holder bohs in the holdeB.
1. After wiping down the camshaft, camshaft seal andjournals in the cylinder head, lubricate both sur-
faces and install the camshaft.
2. Clean and install the oil control orifice with a new
O-ring.
CAMSHAFT SEALSeal housing surface should be dry.Apply a light coat of oil to camshaftand inner lip of seal.
3. Turn the camshaft until its keyway is facing up (No.
piston TDC).

Set the rocker arm assemblY in place and loosely
installthe bolts.- Make sure that the rocker arms are properly posi-
tioned on the valve stems.

lnspection and Adjustment
Pump Pressure Check
Check the fluid pressure as follows to determine
whether the trouble is in the pump or gearbox.
NOTE: First check the power steering fluid level andpump belt tension.
CAUTION: Disconnect the high pr$sure hos€ with care
so as not lo spill the power sieering tluid on tha frame
and other parts.
1. Disconnect the outlet line from the Dumo outlet fit-
ting, then installthe P/S joint adaptor (pump) on the
Dumo outlet.
2. Connect the P/S joint adaptor (hose) to the power
steering pressure gauge, then connect the outlet
hose to the adaptor.
3. Install the power steering pressure gauge to the P/Sjoint adaptor (pump) as shown.

7.
Start the engine and let it idle.
Turn the steering wheel from lock-to-lock several
times to warm the fluid to operating temperature.
Measure steady-state fluid pressure while idling. If
the pump is in good condition, the gauge should
read less than 1500 kPa (15 kgf/cmr, 213 psi).
lf it reads high, check the outlet line or valve body
unit (see General Troubleshooting 17-22).
Close the pressure control valve, then close the
shut-off valve gradually until the pressure gauge
needle is stable. Read the oressure.
lmmediately open the pressure control valve fully.
GAUTION: Do not keep lhe prossure control valve
clos€d more then 5 soconds or the pump could be
damagod by over-heating.
lf the pump is in good condition, the gauge should
read at least 6,400 - 7,400 kPa (65 - 75 kgflcm,, 920 -
1,070 psi). A low reading means pump output is too
low for full assist. Repair or replace the pump,
