Tune-Up Notes

NOTE: When performing tune-up procedures described in this article, these notes and precautions must be followed.

Due to late changes and corrections, always refer to Emission Control Label in engine compartment before attempting tune-up. If label specifications are different than specifications presented here, use label specifications.

Adjustment of injectors or internal adjustment of injection pump must be done in a properly equipped injector shop with clean environment.

Prior to checking compression, ensure battery is fully charged to avoid battery run down. Crank engine through at least 6 compression strokes before recording reading.

CAUTION: DO NOT add oil to cylinders for a wet compression test. The high compression ratio could cause damage to engine or oil could ignite and cause serious bodily harm.
