Withdrawal
1. Remove the toothed belt.
2. Turn out all bolts of fastening of the oil pallet.
3. Remove the oil pan.
4. Turn out 2 bolts and remove the mesh oil filter with an oil receiving pipe.
5. Remove the front cover.
6. Remove the oil pump cover.
7. Remove the inner and outer gears of the oil pump from the front cover, after noting their relative position.
8. Turn out a stopper and remove a spring and a plunger.
Examination
1. Check the front oil seal for wear or damage to the sealing lips and replace if necessary.
2. Check the sealing lip for deterioration. Replace oil seal if necessary.
3. Check the oil pan for cracks or damage and replace if necessary.
4. Check the oil filter for cracks or damage and replace if necessary.
5. Check the front cover for wear or damage where it contacts the oil pump gears and replace if necessary.
6. Check for wear or damage to the oil pump gear teeth.
7. Use a feeler gauge to measure the clearance between the oil pump gear and the socket in the cover. Maximum permissible clearance of the external gear of the oil pump: 0.12–0.185 mm.
8. Using a feeler gauge, measure the gap between the teeth of the oil pump gears. Maximum permissible gap between the teeth of the gears of the oil pump: 0.025–0.069 mm.
9. With a metal ruler and feeler gauge, measure the backlash of the oil pump gears.
- Maximum permissible side clearance of the oil pump rotors: 0.04–0.085 mm.
10. Check the condition of the safety valve located in the front cover.
eleven.. Check the condition of the relief valve spring.
- Spring free length: 43.8 mm
- 2.0/1.8L engines: 43.8 mm
- 1.6L engine: 46.6mm
- Spring length under load 3.7 kg:
- 2.0/1.8L engines: 40.1mm
- Spring length under load 6.1 kg:
- 1.6L engine: 40.1mm
Oil pressure sensor
1. If the engine oil pressure warning light comes on after the ignition is turned on and goes out after the engine is started, the engine oil pressure sensor is good. If the engine oil pressure warning lamp does not come on after the ignition is turned on, check the condition of the oil pressure sensor, lamp, and wiring.
2. If there is an electric current after the ignition is turned on and there is no current after the engine is started, then the engine oil pressure sensor is OK. If the engine oil pressure sensor is OK, check the lamp and wiring.
3. Using a 24 mm deep wrench, tighten the sensor to the required torque.
Checking the oil pressure sensor
1. Using an ohmmeter, check the continuity of the connection between the sensor terminal and the cylinder block. If there is no continuity, replace the sensor.
2. Using an ohmmeter, check the continuity of the connection between the sensor terminal and the cylinder block with the sensor rod extended. If there is continuity even with the stem extended, replace the sensor.
3. However, if there is no conductivity even when a 50 kPa vacuum is applied to the sensor opening, the sensor is working properly.
4. Check the tightness of the sensor diaphragm and, if necessary, replace it.
Installation
Oil pump
1. Install the outer and inner gears of the oil pump in the front cover, after aligning the previously applied marks.
2. Install the oil pump cover and secure it with bolts. After tightening the bolts, check that the gears turn easily and smoothly. Tightening torque: 6–9 Nm.
3. Install the safety valve, spring and wrap the plug, tightening it to the required torque. Lubricate the relief valve with engine oil before installation. Tightening torque: 40–50 Nm.
Front cover
Install the front cover with a new gasket and secure it with bolts.
Bolt length:
- Engines 2.0/1.8 L:
- A - 25 mm
- B - 20 mm
- C - 45 mm
- D - 38 mm
- Engine 1.6L:
- A - 30 mm
- B - 45 mm
- C - 60 mm
- D - 22 mm
Tightening torque: 20–27 Nm.
Oil seal
1. Using special tool 09214-32000, install the crankshaft front oil seal into the front cover.
2. Install special tool 09214-32100 on the front end of the crankshaft and apply a thin coat of oil to the outer surface of the special tool to install the front cover.
3. Install the oil filter.
4. Clean the mating surfaces of the oil pan and cylinder block from the remnants of the old gasket.
5. Apply a continuous coat of sealant to the mating surface of the oil pan. Place the sealant around the bolt holes on the inside.
- 1. The thickness of the sealant layer should be about 4mm.
- 2. Install the oil pan within 15 minutes after applying the sealant.
6. Establish the oil pallet on the block of cylinders and fix with bolts. Tightening torques: 10–12 Nm.
