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
- Remove bolts and oil pump cover.
- Remove inner rotor and outer rotor from front cover.
- 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".
- 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".
- 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).
- Measure the inner diameter of inner rotor (1) using a suitable tool
(A).
- (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.
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.

*Power steering fluid, brake fluid, etc.
