How to change a timming belt on honda civic - 1986 Honda Civic

Timing Belt and Tensioner REMOVAL & INSTALLATION 1984–87 Engines

1. Turn the crankshaft pulley until it is at Top Dead Center.
2. Remove the pulley belt, water pump pulley, crankshaft pulley, and timing gear cover. Mark the direction of timing belt rotation.
3. Loosen, but do not remove, the tensioner adjusting bolt and pivot bolt.
4. Slide the timing belt off of the camshaft timing gear and the crankshaft pulley gear and remove it from the engine.
5. To remove the camshaft timing gear pulley, first remove the center bolt and then remove the pulley with a pulley remover or a brass hammer. This can be accomplished by simply removing the timing belt upper cover, loosening the tensioner bolts, and sliding the timing belt off of the gear to expose the gear for removal. NOTE: If you remove the timing gear with the timing belt cover in place, be sure not to let the woodruff key fall inside the timing cover when removing the gear from the camshaft. Inspect the timing belt. Replace if over 90,000 miles old, if oil soaked (find source of oil leak also), or if worn on leading edges of belt teeth.

6. Be sure to install the crankshaft pulley and the camshaft timing gear pulley in the top dead center position. Align the marks on the camshaft timing gear so they are parallel with the top of the cylinder head and the woodruff key is facing up. NOTE: 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 twist the belt unnecessarily or bend in a 90°angle, since it is made with 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.
   
7. After installing the belt, adjust the belt tension by first rotating the crankshaft counterclockwise 1/4 turn. Then, re-tighten the adjusting bolt and finally the tensioner pivot bolt.
8. Replace the other components removed for belt access.
9. Start the car, check timing and adjust if necessary WARNING
   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.
