Oil Pump: Removal and Installation

Removal

1) Disconnect the battery negative terminal. Refer to [Battery: Removal and Installation] Removal and Replacement.
2) Remove the RH and LH wheels and tires. Refer to [Wheel and Tire Assembly: Adjustment] Service and Repair.
3) Remove the RH and LH front fender protectors. Refer to [Front Fender: Removal and Installation] Service and Repair.
4) Remove the air duct and resonator assembly and the air cleaner case (upper). Refer to [Air Cleaner and Air Duct: Exploded View] Exploded View.
5) Remove timing chain (primary) only. Refer to [Timing Chain: Removal and Installation] Removal and Installation.
6) Remove the oil pump assembly.

Installation

Installation is in the reverse order of removal, paying attention to the following.

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

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 [Recommended Fluids and Lubricants [for USA and Canada] [1][2]Maintenance ] (United States and Canada). Refer to [Recommended Fluids and Lubricants [for Mexico] ] (Mexico).
- 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.
