REMOVAL & INSTALLATION
- Turn the crankshaft pulley until No. 1 is at Top Dead Center of the compression stroke. This can be determined by observing the valves (all closed) or by feeling for pressure in the spark plug hole (with your thumb or a compression gauge) as the engine is turned.
- Remove the pulley belt, water pump pulley (if so equipped), crankshaft pulley, and timing gear cover. Mark the direction of timing belt rotation.
- Loosen, but do not remove, the tensioner adjusting bolt and pivot bolt.
- Slide the timing belt off the camshaft sprocket, crankshaft sprocket, then remove it from the engine.
- To remove the either camshaft or crankshaft timing sprocket, first remove the center bolt and then remove the sprocket with a pulley remover or a brass hammer.
- Reverse the removal procedure. Be sure to position the crankshaft and camshaft timing sprockets in the Top Dead Center position. Torque the camshaft sprocket bolt to 30 ft. lbs.
- When installing the timing belt, do not allow oil to come in contact with the belt. Oil will cause the rubber to swell. Be careful not to bend or twist the belt unnecessarily, since it is made of fiberglass; nor should you use tools having sharp edges when installing or removing the belt. Be sure to install the belt with the arrow facing in the same direction it was facing during removal.
After installing the timing belt, adjust the belt tension by first rotating the crankshaft counterclockwise 1 / 4 turn or 3 teeth on the camshaft pulley. Then, retighten the adjusting bolt and finally the tensioner pivot bolt.
Do not remove the adjusting or pivot bolts, only loosen them. When adjusting, do not use any force other than the adjuster spring. If the belt is too tight, it will result in a shortened belt life.
