4. Remove the driven gear.
5. Remove the drive gear.
6. Undo the cap (6a) and release the oil pressure relief valve (6b).
- Remove the crankshaft front oil seal
Refitting
1. Check that the radial clearance between the driven gear and the pump casing is within the recommended limits.
| Measurement | Value | Validity |
|---|---|---|
| Radial clearance between driven gear and pump casing (mm) | 0.100 ÷ 0.210 | 1.4 16v |
1. Check that the endfloat between the top of the gears and the oil pump cover support plane is within the recommended values.
| Measurement | Value | Validity |
|---|---|---|
| Endfloat between the pump casing support plane and the top of the gears (mm) | 0.025 ÷ 0.070 |
- Check that the height of the pressure relief valve spring is within the recommended values.
| Measurement | Value | Validity |
|---|---|---|
| Height of engine oil pressure limit valve spring under load of 11.73 - 12.51 daN (mm) | 35.0 | 1.4 16v |
- Place the oil pressure relief valve in position and secure it using the cap.
- Place the drive gear and the driven gear in position.
- Place the oil pump cover in position and secure it by tightening the bolts to the recommended torque.
| Component | Fastening | dia | Value (daNm) | Validity |
|---|---|---|---|---|
| ENGINE OIL PUMP COVER | Bolt | M6 | 0.7 | 1.4 16v |
