Examination
Check the cylinder block front cover for cracks or damage and replace if necessary.
Check the front crankshaft oil seal for wear or damage to the sealing lips.
Check the oil pan for breakage, damage or cracks and replace if necessary.
Check the oil receiver for breakage, damage or cracks and replace if necessary.
Check the contact surfaces of the oil pump housing with the pump gears for damage or wear.
Check gear teeth for wear or damage.
Pic. 2.188. Checking the radial clearance between the outer diameter of the driven gear and the socket in the pump housing using a flat feeler gauge
Check the clearance between the outer diameter of the driven gear and the seat in the pump housing (pic. 2.188).
The radial clearance between the outer diameter of the driven gear and the socket in the pump housing should be 0.120–0.185 mm.
The gap between the gear teeth should be 0.025–0.069 mm.
Clearance between the ends of the gears and the plane of the pump housing, mm:
- driven gear - 0.04–0.09;
- drive gear - 0.040–0.085.
Pic. 2.189. Checking the gap between the teeth of the gears with a flat feeler gauge
Check the gap between the teeth of the pump gears (pic. 2.189).
Pic. 2.190. Checking the gap between the ends of the gears and the plane of the pump housing using a flat feeler gauge
Check the gap between the ends of the gears and the plane of the pump housing (pic. 2.190).
Check the ease of movement of the pressure reducing valve plunger in the seat of the pump housing.
Check the pressure reducing valve spring for deformation and broken coils.
Pressure reducing valve spring length, mm:
- in the free state - 46.6;
- under a load of 6.1 kgf - 40.1.
Assembly
Pic. 2.191. Combination of driving and driven gears
Install in the front cover of the cylinder block (oil pump housing) drive and driven gears, making sure that they are correctly positioned on the marks (pic. 2.191).
Install the oil pump cover and tighten the mounting bolts to the specified torque. After tightening the bolts, check the pump gears for smooth rotation.
The moment of an inhaling of bolts of fastening of a cover of the oil pump: 8–12 Н·м.
Install the relief valve plunger and spring after coating the plunger with engine oil. Tighten the pressure reducing valve plug to the specified torque.
Pressure reducing valve tightening torque: 40–50 Nm.
Pic. 2.192. Bolts of fastening of a forward cover of the block of cylinders (marked with Latin letters)
Install the front cover of the cylinder block with a new gasket and tighten the mounting bolts (pic. 2.192.) the specified moment.
The moment of an inhaling of bolts of fastening of a forward cover of the block of cylinders: 20–27 Н·м.
Bolt length:
- A: 30 mm;
- H: 45mm;
- C: 60 mm;
- D: 22 mm.
Installing the oil pump housing seal
Pic. 2.193. Installing a special tool
Install special tool (gland guide 09214-32100) into the hole in the oil pump housing (pic. 2.193).
Pic. 2.194. Pressing in the front crankshaft oil seal
Press the oil seal into the hole in the front cover of the cylinder block with a mandrel (pic. 2.194).
Install the oil receiver.
Clean both sides of the oil pan gasket and the mating surface of the cylinder block.
Pic. 2.195. Applying sealant to the oil sump flange
Apply sealant to the oil sump flange groove (pic. 2.195).
Note. The thickness of the sealant bead should be approximately 4 mm.
The oil sump must be installed no later than 15 minutes after applying the sealant.
Install the oil sump and tighten its mounting bolts to the specified torque.
The moment of an inhaling of bolts of fastening of an oil crankcase: 10–12 Н·м.
Checking the Oil Pressure Warning Light Sensor
Pic. 2.196. Checking the presence of an electrical circuit between the output and the sensor housing using an ohmmeter
Check with an ohmmeter the presence of an electrical circuit between the output and the sensor housing (pic. 2.196). If there is an open circuit, replace the sensor.
Pic. 2.197. Checking the presence of an electrical circuit between the output and the sensor housing when pressing the sensitive element of the sensor using an ohmmeter
Check the presence of an electrical circuit between the terminal and the sensor housing when pressing the sensor sensing element (pic. 2.197). If the circuit does not open when the sensor is pressed, replace the sensor.
Create a vacuum of 50 kPa in the sensor through the oil supply hole. If at the same time there is no electrical circuit between the output and the sensor housing, then the sensor is working.
Make sure the sensor is sealed. The presence of a leak indicates a broken sensor diaphragm. Replace sensor with damaged diaphragm.
