  1. Remove the timing gear cover.
  2.  
  3. Use a puller to remove both the crankshaft and the crankshaft and the camshaft gear from the engine after removing all attaching nuts and bolts.
  4.  
  5. Remove the Woodruff keys.
  6.  
  7. Install the Woodruff keys in the longer of the two keyways on the front end of the crankshaft.
  8.  
  9. Install the crankshaft timing gear on the front end of the crankshaft with the timing mark facing away from the cylinder block.
  10.  
  11. Align the keyway in the gear with the Woodruff key and then drive or press the gear onto the crankshaft firmly against the thrust washer.
  12.  
  13. Turn the camshaft or the crankshaft as necessary so that the timing marks on the two gears will be together after the camshaft gear is installed.
  14.  
  15. Install the Woodruff key in the keyway on the front of the camshaft.
  16.  
  17. Start the large timing gear on the camshaft with the timing mark facing out.
  18.  

Do not drive the gear onto the camshaft, as the camshaft may drive the plug out of the rear of the engine and cause an oil leak.

  1. Install the camshaft retaining screw and torque it to 30-40 ft. lb. This will draw the gear onto the camshaft as the screw is tightened. Standard running tolerance between the timing gears is 0 to 0.002 in.
