Camshaft/Rocker Arms and

Camshaft Seal

Installation

CAUTION:

• Make sure that all rockers are in alignment with their

valves when torquing the rocker assembly bolts.

• Valve locknuts should be loosened and adjusting

screws backed off before installation.

• To prevent the rocker arm assembly from coming

apart, leave the camshaft holder bolts in the holes.

1. After wiping down the camshaft and journals in the

cylinder head, lubricate both surfaces and install the

camshaft.

2. Install the camshaft seal with the open side (spring)

facing in.

Lubricate the cam lobes after reassembly.

Five-step Troubleshooting

1. Verify The Complaint

Turn on all the components in the problem circuit to

verify the customer complaint. Note the symptoms.

Do not begin disassembly or testing until you have

narrowed down the problem area.

2. Analyze The Schematic

Look up the schematic for the problem circuit.

Determine how the circuit is supposed to work by

tracing the current paths from the power feed

through the circuit components to ground. If several

circuits fail at the same time, the fuse or ground is a

likely cause.

Based on the symptoms and your understanding of

the circuit operation, identify one or more possible

causes of the problem.

3. Isolate The Problem By Testing The Circuit

Make circuit tests to check the diagnosis you made

in step 2. Keep in mind that a logical, simple proce-

dure is the key to efficient troubleshooting. Test for

the most likely cause of failure first. Try to make

tests at points that are easily accessible.

4. Fix The Problem

Once the specific problem is identified, make the

repair. Be sure to use proper tools and safe proce-

dures.

5. Make Sure The Circuit Works

Turn on all components in the repaired circuit in all

modes to make sure you've fixed the entire prob-

lem. If the problem was a blown fuse, be sure to

test all of the circuits on the fuse. Make sure no new

problems turn up and the original problem does not

recur.
Wire Color Codes

The following abbreviations are used to identify wire

colors in the circuit schematics:

WHT .............................White

YEL ............................... Yellow

BLK .............................. Black

BLU
..............................
Blue

GRN ............................. Green

RED
..............................
Red

ORN ............................. Orange

PNK.............................. Pink

BRN .............................. Brown

GRY.............................. Gray

PUR .............................. Purple

LT BLU ......................... Light Blue

LT GRN ........................ Light Green

The wire insulation has one color or one color with

another color stripe. The second color is the stripe.

WHT/BLK

NOTE: Different wires with the same color in the same

system have been given number suffixes to distinguish

them (for example, YEL1 and YEL2 are not the same).ProCarManuals.com

7. Lower the steering column assembly.

8. Center-punch each of the two shear bolts, and drill

their heads off with a 5 mm (3/16 in) drill bit.

CAUTION: Do not damage the switch body when

removing the shear bolts.

9. Remove the shear bolts from the switch body, then

remove the steering lock assembly.
Installation:

1. Install the new ignition switch without the key

inserted.

2. Loosely tighten the new shear bolts.

3. Insert the ignition key, and check for proper opera-

tion of the steering wheel lock and that the ignition

key turns freely.

4. Tighten the shear bolts until the hex heads twist off.
