Withdrawal
1. Remove the toothed belt.
2. Remove all oil pan bolts.
3. Remove the oil pan.
4. Remove the oil receiver and gasket.
5. Remove the plunger and gasket, and then remove the spring and valve from the oil filter bracket hole.
6. Remove the oil pressure sensor.
7. Remove the oil filter bracket and gasket.
8. Using a special tool, remove the cap from the front cover in the oil pump area.
9. Remove the plug from the left side of the cylinder block and insert a screwdriver with a rod diameter of 8 mm into the opened hole. The screwdriver shank must be inserted more than 60 mm.
10. Remove the oil pump drive gear and the left balance shaft mounting bolt.
11. Turn out bolts of fastening of a forward cover and remove a forward cover and a lining. Remove both balance shafts from the front cover.
12. Remove the oil pump cover from the front cover.
13. Remove the oil pump gears from the front cover.
Examination
Front cover
1. Check for clogged oil passages and clean if necessary.
2. Check the balance shaft front bearing area for wear, damage, and nicks. Replace if necessary front cover.
3. Check for cracks or other damage on the front cover. Replace a damaged or cracked front cover.
Balance shaft
Check the necks for wear and tear.
In case of excessive wear and scoring, check the bearing.
If necessary, replace the balance shaft bearing, or both.
Stuffing box
1. Check the seal lip for wear and damage. Replace seal if necessary.
2. Check the seal lip for damage. Replace if necessary.
Oil pressure sensor
1. Using an ohmmeter, check the electrical conductivity between the terminal and the housing. If it is missing, replace the sensor.
2. Check the electrical conductivity between the terminal and the body when inserting a thin wire into the sensor hole. If there is continuity, replace the sensor.
3. If there is no electrical conductivity when a vacuum of 50 kPa is created in the oil tube, the sensor works normally. Make sure there is no air leakage. The presence of air leakage indicates a diaphragm rupture. Replace sensor.
Oil pump
1. Install the oil pump gears and rotate them to check for ease of rotation and no play.
2. Make sure that there are no wear grooves on the surface of the cover and gears of the oil pump.
3. With the gears installed, measure the clearance at the tops of the gear teeth.
Balance shaft bearings
Replacement
1. Using the special tool, remove the right balance shaft front bearing from the cylinder block.
2. Using the special tool, remove the right balance shaft rear bearing from the cylinder block.
3. Using the special tool, remove the left balance shaft rear bearing from the cylinder block. At this time, install the special tool on the front surface of the cylinder block to hold the bearing puller.
4. Using the special tool, install the left balance shaft rear bearing into the cylinder block.
Note:
- 1. Lubricate the outer surface of the rear bearing and the mounting hole in the cylinder block with engine oil.
- 2. The left rear bearing has no oil holes.
5. Using the special tool, install the right balance shaft rear bearing into the cylinder block.
Note:
- 1. Lubricate the outer surface of the bearing with engine oil.
- 2. Make sure the lubrication hole of the bearing is aligned with the lubrication hole of the cylinder block.
6. Using the special tool, install the right balance shaft front bearing into the cylinder block.
Note. Make sure the lubrication hole of the bearing is aligned with the lubrication hole of the cylinder block.
Installation
1. Apply engine oil to the gears and align the timing marks.
2. Using a special tool, a device for installing the front crankshaft oil seal (09214-32000), install the crankshaft front oil seal into the front cover.
3. Install special tool (09214-32100) on the front end of the crankshaft and apply a light coat of engine oil to the outside of the front cover installation tool.
4. Install the front cover on the new gasket and temporarily tighten the mounting bolts (except for the oil filter bracket bolts).
5. Install the front cover on a new gasket and tighten the bolts to the required torque.
Front cover:
- Torque:
- * 27—34 Nm
- 20—27 Nm
- Everything except the oil pump bracket bolts - 15-22 Nm
6. Insert a screwdriver through the plug hole on the left side of the cylinder block to hold the shaft in position, and then tighten the nut.
7. Install a new o-ring into the front cover groove and torque tighten.
8. Using the special tool, install the plug cap and tighten it to the required torque.
9. Apply sealant to the oil sump flange groove as shown.
Note:
- 1) Apply sealant approximately 4 mm thick.
- 2) After applying the seal, install the oil sump within 15 minutes at the latest.
10. Note the difference in bolt length in the location shown. Install the oil sump and tighten the bolts to the correct torque.
- Tightening torque: Oil pan bolts - 6-8 Nm
11. Using the special tool, install the oil pressure sensor after applying sealing compound to its threaded part.
- Sealant - Threebond 1104 or equivalent
Note. Do not overtighten the oil pressure switch.
- Tightening torque: Oil pressure sensor - 8-12 Nm
