Components

Disassembly of oil pump

(See Removal of oil pump)

  1. Remove relief valve.

    1. Using snap ring pliers, remove the snap ring.
    2. Remove the retainer, spring and relief valve.

  2. Remove drive and driven rotors.

    Remove the two bolts, pump body cover, O-ring, the drive and driven rotors.

Inspection of oil pump

  1. Inspect relief valve.

    Coat the valve with engine oil and check that it falls smoothly into the valve hole by its own weight.

    If it doesn't, replace the relief valve. If necessary, replace the oil pump assembly.

  2. Inspect drive and driven rotors.

    A. Inspect rotor body clearance

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

    Standard body clearance: 0.100 – 0.160 mm (0.0039 – 0.0063 in.)

    Maximum body clearance: 0.20 mm (0.0079 in.)

    If the body clearance is greater than maximum, replace the rotors as a set. If necessary, replace the oil pump assembly.

    B. Inspect rotor tip clearance

    Using a feeler gauge, measure the clearance between the drive and driven rotors.

    Standard tip clearance: 0.040 – 0.160 mm (0.0016 – 0.0063 in.)

    Maximum tip clearance: 0.20 mm (0.0079 in.)

    If the tip clearance is greater than maximum, replace the rotors as a set.

Replacement of oil pump oil seal

  1. Remove oil seal.

    Using a screwdriver, pry out the oil seal.

  2. Install oil seal.

    1. Using SST and a hammer, tap in a new oil seal until its surface is flush with the oil pump cover edge.

      SST 09620-30010 (09627-30010, 09631-00020)

    2. Apply MP grease to the oil seal lip.

Replacement of crankshaft front oil seal

(See Cylinder block (3S-GTE) › Replacement of crankshaft oil seals)

Assembly of oil pump

(See Removal of oil pump)

  1. Install drive and driven rotors.

    1. Place the drive and driven rotors into pump body with the marks facing the pump body cover side.

    2. Install a new O-ring to the pump body.

    3. Install the pump body cover with the two bolts.

      Torque: 90 kg-cm (78 in.-lb, 8.8 N·m)

  2. Install relief valve.

    1. Insert the relief valve, spring and retainer into the pump body hole.
    2. Using snap ring pliers, install the snap ring.

Installation of oil pump

(See Oil pump)

  1. Install oil pump.

    Install a new gasket and the oil pump with the twelve bolts.

  6. Install oil pan.

    1. Remove any old packing (FIPG) material and be careful not to drop any oil on the contact surfaces of the oil pan and cylinder block.

      • Using a razor blade and gasket scraper, remove all the old packing (FIPG) material from the gasket surfaces and sealing groove.
      • Thoroughly clean all components to remove all the loose material.
      • Using a non-residue solvent, clean both sealing surfaces.

      Hint

      Avoid applying an excessive amount to the surface. Be particularly careful near oil passages.

      • Parts must be assembled within 5 minutes of application. Otherwise the material must be removed and reapplied.
      • Immediately remove nozzle from the tube and reinstall cap.
