To check main bearing-to-iournal oil clearance,
remove the main caps and bearing halves.
Clean each main iournal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main iour-
na l-
NOTE: lf the engine is still in the car when you bolt
the main cap down to check clearance, the weight
of the crankshaft and flywheel will flatten the plasti'
gage further than just the torque on the cap bolt,
and give you an incorrect reading. For an accurate
reading, support the crank with a jack under the
counterweights and check only one bearing at a
trme.
Reinstall the bearing caps and cap bridge (B18C1,
B18C5 engines only)then torque the bolts.

NOTE: Do not rotate the crankshaft during inspec-
tro n.
Remove the cap bridge (818C1, 818C5 engines
only), caps and bearings again, and measure the
widest part of the plastigage.

PLASTIGAGE STRIP
lf the plastigage measures too wide or too narrow,
{remove the engine if it's still in the car), remove the
crankshaft, and remove the upper half of the bear-
ing. lnstall a new, complete bearing with the same
color code (select the color as shown in the right
column), and recheck the clearance.
CAUTION: Do not file, shim. or scrape the bearings
or the caps to adiust clearance.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again.
NOTE: lf the oroDer clearance cannot be obtained
by using the appropriate larger or smaller bearings.
reolace the crankshaft and start over.

CAUTION: lf the codes ale indecipherable because of
an accumulation oI dirt and dust, do not scrub them
with a wire bru6h or scraper. Clean lhem only with sol-
vent or detergent.

INPUT SHAFT
High assist at lower speedsl
When steering resistance is high, such as when driving at low speed, or when turning the wheel with the car stopped, the
diiference in angle created between the input shaft and the valve opens the tluid passage on one side, and closes the fluidpassage on the other side, at each pair of orifices. The fluid pressure lncreases in the side of the power cylinder fed by thelarger fluid passage. This increased pressure pushes on the rack piston, allowing the steering wheel to be turned with light
effon. On the other side of the power cylinder, the return passage opens allowing the steering fluid to return through theinput shaft to the reservoir. The fluid passages to the power cylinder automatically change in size, increasing as the steer-ing resistance increases. In other words, the passages become larger and power assist increases when the steering effort
would normally be high, (for example, when parking or making low speed turns), and the passages become smaller andpower assist decreases when the steering effort would normally be low, (for example, when driving at high speeds or
straight ahead).

Pressure Control
Low assist at higher speedsl
When steering resistance is low, such as when driving at high speeds, or when driving straight ahead. the lnput shaft is
near or in the neutral position, so there is liftle or no flow to any of the power cylinder orifices. Most of the feed pressure
from the pump is bypassed to the reservoir. Because of this, the pressure stays the same in both sides of the power cvlin-
der, resulting in low or no assist.

Troubleshooting
General Troubleshooting
Check the following before you begin:
o Has the suspension been modified in a way that would affect steering?
. Are tire sizes and air pressure correct?
. lsthe steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adiusted?
. ls steering fluid reservoirtilled to proper level?
. ls the engine idle speed correct and steadyT
Hard steering (check the power assist, see page 17-18. It the torce is over 34 N (3.5 kgf, 7 7 lbf), proceed with this troubl*hooting l

Wheel Alignment
Caster
NOTE: For proper inspection/adjustment of the wheel
alignment check and adjust the following before check-
ing the alignment.
. Check that the susoension is not modified.
. Check the tire size and tire pressure.
. Check the runout of the wheels and tires.
. Check the suspension ball joints. (Hold a wheel with
your hands and move it up and down and right and
left to check tor wobbling.)
Inspection
NOTE: Use commercially-available computerized four
wheel alignment equipment to measure wheel align-
ment {caster, camber, toe, and turning angle). Follow
the equipment manufacturer's instructions.
1. Check the caster angle.
Casler angle: 1'10't 1"
2. lf out of specification. check for bent or damaged
suspension compohents.
