Withdrawal
Pic. 2.314. Removing the switch sensor
Using a 24 mm tool socket, unscrew the oil pressure switch (pic. 2.314).
Note. The sensor is installed on the sealant, be careful not to damage the sensor.
Remove the oil filter and oil pan.
Remove the oil pan.
Remove the three mounting bolts and remove the oil filter bracket and gasket.
Turn out a stopper of the reducing valve, remove a spring and a plunger.
Remove the oil pump housing assembly.
Checking the oil pump housing
Check the oil pump housing for cracks or damage. Replace if necessary.
Pic. 2.315. Oil Pump Clearance Measurement
Measure the clearance between the outer surface of the outer gear and the pump housing (pic. 2.315).
Measure the end clearance of the gears.
Oil pump gaps.
Rated value:
- the gap between the outer surface of the outer gear and the pump housing is 0.100–0.181 mm;
- end clearance - 0.040–0.095 mm.
Pressure reducing valve and spring check
Check the ease of movement of the pressure reducing valve plunger in the oil pump housing.
Check the condition of the pressure reducing valve spring (no breakage or deformation).
Checking the oil filter bracket
Check for damage to the mating surface of the oil filter
Check for cracks and signs of oil leakage.
Checking the oil pressure switch
Pic. 2.316. Checking for a closed circuit between the output and the body of the sensor-switch
Using an ohmmeter, check for a closed circuit between the terminal and the sensor-switch housing. If the circuit is open, replace the switch (pic. 2.316).
Pic. 2.317. Checking for a closed circuit using a thin rod
Insert thin rod (or wire) into the opening of the sensor-switch and lightly push it inwards. If the circuit between the output and the body of the sensor-switch is closed with the rod inserted, then replace the sensor-switch (pic. 2.317).
If the circuit between the output and the body of the sensor-switch is open, when a vacuum of 50 kPa acts on the diaphragm of the sensor-switch through the hole, then the sensor-switch is working. If the vacuum is not maintained, then the diaphragm is destroyed. Replace sensor switch.
Sensor response pressure.
Oil pressure switch: 20–40 kPa.
Installation
Pic. 2.318. oil pump housing
Install the oil pump housing assembly on the new gasket (pic. 2.318).
Pic. 2.319. Installing the crankshaft oil seal
With mandrel (09214-33000) install the crankshaft seal (all the way to the wall of the nest) (pic. 2.319).
Install pressure relief valve plunger and spring. Tighten the plug to the rated torque.
Pressure reducing valve tightening torque: 40–50 Nm.
Install the oil pickup on the new gasket.
Tightening torque of the oil intake bolts: 15–22 Nm.
Clean the mating surfaces of the block and oil pan.
Pic. 2.320. The scheme of applying sealant to the flange of the pallet
Apply a bead of sealant to the groove of the sump flange (pic. 2.320).
Note. Cut off the nose of the sealant tube so that the diameter of the sealant bead is approximately 4 mm. The tray must be installed within 15 minutes after applying the sealant.
Note. The sealant must not get inside the pan.
Establish the oil pallet and tighten bolts of its fastening the nominal moment.
Tightening torque for oil pan bolts:
- * - 19–28 Nm;
- ** - 5–7 Nm;
- *** - 30–42 Nm.
Pic. 2.321. The procedure for tightening the oil pan bolts
The order of an inhaling of bolts of fastening of the pallet is shown in drawing 2.321.
Apply sealant to the threads of the oil pressure switch and tighten the switch to the specified torque.
Three Bond Sealant No. 1141E or 3M ATD No. 8660 or equivalent.
Note. Do not exceed the rated torque of the sensor.
Tightening torque for oil pressure switch: 15–22 Nm.
Pic. 2.322. The order of tightening the bolts of the lower pallet
Tighten bolts of fastening of the bottom pallet in the order specified in drawing 2.322.
