ADJUSTMENT

IGNITION TIMING

Service repair no - 86.35.15

Adjust

1. It is essential that following procedures are

adhered to. Inaccurate timing can lead to serious
engine damage and additionally create failure to
comply with emission regulations. If timing is
being checked in vehicle, air conditioning
compressor must be disengaged.

2. On initial engine build, or if distributor has been

disturbed for any reason, ignition timing must be
set statically to the figure given:

If engine is 3.9 V8.

See ENGINE TUNING

DATA, Information, ENGINE - 3.9 V8

If engine is 4.2 V8.

See ENGINE TUNING

DATA, Information, ENGINE - 4.2 V8

NOTE: This approximate setting is made
only to ensure that engine may be started.

CAUTION: On no account must engine be
started before this operation is carried out.

Equipment required :-

Calibrated Tachometer
Stroboscopic lamp

3. Couple stroboscopic timing lamp and tachometer

to engine following manufacturer’s instructions.

4. Disconnect vacuum hose from distributor.
5. Start engine. With no load, and without

exceeding 3,000 rev/min run engine until normal
operating temperature is reached. (Thermostat
open). Check that engine idles within tolerance.

If engine is 3.9 V8 check tolerance in.

See

ENGINE TUNING DATA, Information, Engine
- 3.9 V8

If engine is 4.2 V8 check tolerance in.

See

ENGINE TUNING DATA, Information, Engine
- 4.2 V8

6. Idle speed for timing purposes must not exceed

800 rev/min.

7. Run engine at idle speed and check timing using

stroboscope light on timing marker and pointer.

WARNING: Keep hands and equipment
away from drive belt.

8. If timing is not as specified, switch off engine.

Loosen distributor clamp bolt and turn distributor
to advance or retard ignition as necessary.
Tighten clamp bolt, start engine and recheck
timing.

WARNING: Personal injury may result if an
attempt is made to adjust distributor whilst
engine is running.

9. Upon completion, switch off engine and tighten

distributor clamping bolt securely. Recheck
timing, to ensure retightening has not disturbed
distributor position.

10. Refit vacuum hose.
11. Disconnect stroboscopic timing lamp and

tachometer from engine.
