Масляный Насос Проверка. Corolla Auris

Apply engine oil to the oil pump relief valve. Check that the valve falls smoothly into the valve hole of the oil pump body by its own weight.

Check the tip clearance.

1. Using a feeler gauge, measure the clearance between the tips of the drive rotor and driven rotor.
   

   Standard tip clearance:

   0.060 to 0.180 mm (0.0024 to 0.0071 in.)
   

   Maximum tip clearance:

   0.28 mm (0.0110 in.)
   

   If the tip clearance is greater than the maximum, replace the oil pump assembly.
   

Check the body clearance.

1. Using a feeler gauge, measure the clearance between the driven rotor and oil pump body.
   

   Standard body clearance:

   0.250 to 0.325 mm (0.0098 to 0.0128 in.)
   

   Maximum body clearance:

   0.43 mm (0.0167 in).
   

   If the body clearance is greater than the maximum, replace the oil pump assembly.
   

Check the side clearance.

1. Using a feeler gauge and precision straight edge, measure the clearance between the rotors and precision straight edge.
   

   Standard side clearance:

   0.030 to 0.090 mm (0.0012 to 0.0035 in).
   

   Maximum side clearance:

   0.150 mm (0.0059 in.)
   

   If the side clearance is greater than the maximum, replace the oil pump assembly.
