Fig. View of the 12 point crankshaft sprocket

The 12 point crankshaft sprocket bolt is meant to be used one time only and must be replaced when removed.

  1. Remove the timing belt covers and the timing belt. The crankshaft sprocket should slide off easily when the center bolt is removed. Don't lose the Woodruff key.
  3. Remove the cylinder head cover.
  5. Use a wrench to hold the camshaft on the flat section and remove the sprocket retaining bolt.
  7. Gently pry or tap the sprocket off the shaft with a soft mallet. If the sprocket will not easily slide off the shaft, use a gear puller.

.Do not hammer on the sprocket or damage to the sprocket or bearings could occur.

On 16 valve engines, make sure the camshaft sprockets are installed so that the curved portion of the sprocket key faces the surface of the engine block. If the sprocket is installed incorrectly, the timing will be advanced and cause the valves to hit the pistons.

  1. Installation is the reverse of removal. On crankshaft sprocket bolts, oil the threads before installing the bolt. Torque the bolts as follows:

    Camshaft sprocket on 8 valve gasoline engines-59 ft. lbs. (80 Nm).
    Camshaft sprocket on 16 valve engines-48 ft. lbs. (65 Nm).
    Camshaft sprocket on diesel engines-33 ft. lbs. (45 Nm)
    Crankshaft sprocket 6 sided bolt-137 ft. lbs. (180 Nm).
    Crankshaft sprocket 12 sided bolt-66 ft. lbs. (90 Nm) plus 1 / 2 turn.
    Install the timing belt, check valve timing, adjust the belt tension, and install the covers.
