Removal and Installation

REMOVAL

Remove front cover. Refer to EM-44, "Exploded View".

NOTE: Oil pump is built into front cover.

INSTALLATION

Installation is in the reverse order of removal.

  •  When installing, align crankshaft flat faces with inner rotor flat faces.

Disassembly and Assembly

DISASSEMBLY

  1.  Remove bolts and oil pump cover.
  2.  Remove inner rotor and outer rotor from front cover.
  3.  After removing regulator valve plug, remove regulator valve spring and regulator valve.

ASSEMBLY

Assembly is in the reverse order of disassembly.

  • Install the inner rotor and outer rotor with the punched marks on the oil pump cover side.

CAUTION: Before assembly apply new engine oil to the parts specified.

Inspection

INSPECTION AFTER DISASSEMBLY

OIL PUMP CLEARANCE

  •  Measure the clearance using a suitable tool (A).
  •  Clearance between outer rotor (B) and front cover (C)

Standard : Refer to LU-17, "Oil Pump".

  • Tip clearance between inner rotor and outer rotor (B)

Standard : Refer to LU-17, "Oil Pump".

Inspection after disassembly

  • Measure the clearance using suitable tools (A/B).
  •  Side clearance between inner rotor (3) and front cover (1)

Standard : Refer to LU-17, "Oil Pump".

  • Side clearance between outer rotor (2) and front cover (1)

Standard : Refer to LU-17, "Oil Pump".

Inspection after disassembly

  • Calculate the clearance between oil pump inner rotor and oil pump body as follows:
  •  Measure the outer diameter of protruded portion of inner rotor (1) using a suitable tool (A).

Inspection after disassembly

  • Measure the inner diameter of inner rotor (1) using a suitable tool (A).

Inspection after disassembly

  • (Clearance) = (Inner rotor inner diameter) – (Oil pump inner rotor outer diameter)

Standard : Refer to LU-17, "Oil Pump".

  • If measured/calculated values are out of the standard, replace front cover and oil pump assembly.

REGULATOR VALVE TO OIL PUMP COVER CLEARANCE

  •  (Clearance) = (Regulator valve hole (1) diameter) – (Regulator valve (2) outer diameter)

Standard : Refer to LU-17, "Oil Pump".

  • If the calculated value is out of the standard, replace front cover and oil pump assembly.

CAUTION:

  •  Coat regulator valve with engine oil.
  •  Make sure that it falls smoothly into valve hole by its own weight.

Regulator valve to oil pump cover clearance

INSPECTION AFTER INSTALLATION

  •  Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to MA-11, "Fluids and Lubricants".
  •  Use procedure below to check for fuel leaks.
  •  Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks at connection points.
  •  Start engine. With engine speed increased, check again for fuel leaks at connection points.
  •  Run engine to check for unusual noise and vibration.

NOTE: If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.

  •  Warm up engine thoroughly to make sure there are no leaks of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
  •  Bleed air from passages in lines and hoses, such as in cooling system.
  •  After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to specified level, if necessary.
  •  Summary of the inspection items:

*Power steering fluid, brake fluid, etc.
