Removal, check and installation of the oil pump
Withdrawal Remove the timing belt. Remove the bolts from the oil pan. Remove the oil sump. Remove the oil receiver the oil pump.
Remove the front cover of the cylinder block (oil pump housing) assembly (Fig. 2.187). Remove the front cover of the cylinder block (oil pump housing) assembly. Remove the drive and driven gears of the front cover of the cylinder. On the driving and driven gear mating marks.
Check Check the front cover of the cylinder block for cracks or damage and replace it if necessary. Inspect the crankshaft oil seal for wear or damage working edges. Check the sump for any breakages, damage or cracks and replace it if necessary. Check ups on the existence of damage, damage or cracks and replace it if necessary. Check the contact surface of the housing of the oil pump with gear pump for damage or wear. Check the gear teeth for wear or damage.

|
Check the clearance between the outer diameter of the driven gear and the socket in the pump housing (Fig. 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 teeth of gears should be 0,025-0,069 mm. The gap between the ends of the gears and the pump housing plane, mm - Driven gear - 0.04-0.09; - Drive gear - 0,040-0,085.

|
Check the clearance between the teeth of the gear pump (Fig. 2.189).
| Fig. 2.190. Checking gap between the ends of the gears and the plane of the pump housing with a flat probe
|
Check the gap between the ends of the gears and the pump casing plane (Fig. 2.190). Check the ease of movement of the plunger pressure reducing valve in the socket casing. Check relief valve spring for deformation and breakage of turns. The length of the spring relief valve, mm: - In a free state - 46.6; - Under a load of 6.1 kg - 40.1.
Assembly
Set the front cover of the cylinder block (oil pump housing) master and slave gear, ensuring their correct location on the label (Fig. 2.191). Install the oil pump cover and tighten the bolts to the specified torque. After tightening the bolts, check for smooth rotation gear pump. Tightening torque cover bolts of the oil pump: 8-12 Nm. Install the plug and spring relief valve, pre-coated with engine oil plug. Tighten the cap reducing valve to the specified torque. Tightening torque reducing valve plug: 40-50 Nm.

|
Install the front cover of the cylinder block with a new gasket and tighten the bolts (Fig. 2.192.) Specified torque. Tightening torque of the mounting bolts of the front cover of the cylinder: 20-27 Nm. Length of bolts: A: 30 mm; B: 45 mm; C: 60 mm; D: 22 mm.
Install the gland body of the oil pump
Install special tool (guide bush oil seal 09214-32100) into the hole of the oil pump housing (Fig. 2.193).
| Fig. 2.194. Pressing the front crankshaft oil seal
|
Press-fit the oil seal into the hole of the front cover of the cylinder mandrel (Fig. 2.194). Install the oil receiver. Clean both sides of the oil pan gasket and the mating surface of the cylinder.
| Fig. 2.195. The application of sealant on the flange of the oil pan
|
Apply sealant into the groove of the flange the oil sump (Fig. 2.195).
NOTE The thickness of the bead of sealant should be about 4 mm. |
The oil sump must be installed no later than 15 minutes after applying the sealant.
Install the oil pan and tighten the bolts attaching it to the specified torque. Tightening torque of fastening oil crankcase: 10-12 Nm. Check of the gauge of a control lamp of pressure of oil

|
Check availability ohmmeter circuit between the terminal and the housing of the sensor (Fig. 2.196). If there is an open circuit, replace the sensor.
| Fig. 2.197. Checking the electrical circuit between the terminal and the housing of the sensor by pressing the sensing element with an ohmmeter
|
Check the circuit between the terminal and the housing of the sensor by pressing the sensor of the sensor (Fig. 2.197). If you click on the sensor circuit does not open, replace the sensor. Create a vacuum in the sensor size of 50 kPa through the hole for the oil supply. If the circuit between the terminal and the housing of the sensor is not present, then the sensor is defective. Verify sensor integrity. Leakage points to open the diaphragm of the sensor. Sensor to replace a damaged diaphragm.
