Cylinder Block - Overview (001-999) General Information Barring Mechanism The barring mechanism is inside the front cover.
The front cover must be removed from the engine to service or rebuild the barring mechanism. The barring mechanism contains a spring-loaded worm gear. The worm gear engages the camshaft gear when the barring shaft is pushed in the front cover and turned in a counterclockwise direction. The barring mechanism will only turn the engine in the direction of normal rotation. Turn the barring shaft in a clockwise direction to disengage the worm gear. If the worm gear remains engaged accidentally during engine start-up, engine rotation will disengage the barring mechanism without damage to it.
