OIL PUMP

Removal and Installation


REMOVAL

1.Drain engine oil. Refer to "Draining" Draining.
2.Remove timing chain and oil pump drive chain. Refer to "Removal and Installation" Removal And Installation.





3.Loosen the oil pump bolts in the reverse order as shown.
4.Remove oil pump and O-rings.

CAUTION:
- Do not reuse O-rings.
- Do not disassemble oil pump.

INSTALLATION

1.Install new O-rings on the oil pan (upper) before installing the oil pump. Refer to "Exploded View" Exploded View.

CAUTION:
Do not reuse O-rings.
2.Install the oil pump.





3.Tighten the oil pump bolts to specification in the order shown.
4.Install timing chain and oil pump drive chain. Refer to "Removal and Installation" Removal And Installation.

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.
- Use procedure below to check for fuel leakage.
- Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
- Start engine. With engine speed increased, check again for fuel leakage 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 is no leakage 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.
