REMOVAL & INSTALLATION



  1. Disconnect the negative battery cable.
  2.  
  3. Remove the valve cover(s) and timing belt(s).
  4.  
  5. Remove the crankshaft pulley retainer bolts and remove the pulley.
  6.  
  7. Remove the crankshaft sprocket retainer bolt and washer from the sprocket, if used, and remove sprocket. If sprocket is difficult to remove or there are no bolts on the puller, the appropriate puller should be used to facilitate remove.
  8.  
  9. Hold the camshaft stationary using the hexagon cast between journals No. 2 and 3 and remove the retainer bolt. Remove the sprocket from the camshaft. If the camshaft does not have a hexagon cast between journals No. 2 and 3, use the appropriate spanner wrench to hold the shaft in position while removing the bolt.
  10.  
  11. Pry the seals from the bores and replace using the proper installation tools.
  12.  
  13. The sprockets should be inspected and replaced if there is any sign of damaged teeth or cracking. Do not immerse sprockets in solvent, as solvent that has soaked into the metal may cause deterioration of the timing belt later.
