CAUTION
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your hands and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used.

  1. Remove the oil pump-to-rear main bearing cap bolt. Remove the pump and the extension shaft.
  2.  
  3. Remove the cotter pin, spring and pressure regulator valve.

Place your thumb over the pressure regulators bore before removing the cotter pin, as the spring is under pressure.

To install:
  1. Assemble pump and extension shaft to rear main bearing cap, aligning slot on top end of extension shaft with drive tang on lower end of distributor driveshaft.
  2.  

When assembling the driveshaft extension to the driveshaft, the end of the extension nearest the washers must be inserted into the driveshaft.
