1 – plug, 40–50 Nm; 2 – sealing ring; 3 – plunger; 4 – bolt, 12–15 Nm; 5 – front sealing ring; 6 – front cover; 7 – internal gear of the oil pump; 8 – external gear of the oil pump; 9 – oil pump cover; 10 – gasket; 11 – gasket; 12 – oil intake tube; 13 – bolt, 15–22 Nm; 14 – oil pan; 15 – oil filter.
Removal
1. Remove the timing belt.
2. Remove all oil pan mounting bolts.
3. Remove the oil pan.
4. Remove 2 bolts and mesh oil filter with oil intake pipe.
5. Remove the front cover.
6. Remove the oil pump cover.
7. Remove the internal and external gears of the oil pump from the front cover, having previously marked their relative positions.
8. Unscrew the plug and remove the spring and plunger.
Examination
1. Check the oil pan for cracks or damage and replace it if necessary.
2. Check the oil filter for cracks or damage and replace it if necessary.
3. Check the front cover for wear or damage where it contacts the oil pump gears and replace if necessary.
4. Check the oil pump gear teeth for wear or damage.
5. Use a feeler gauge to measure the gap between the oil pump gear and the socket in the cover.
Maximum allowable clearance of the external gear of the oil pump: 0.12–0.18 mm
6. Use a feeler gauge to measure the gap between the teeth of the oil pump gears.
Maximum permissible clearance between the teeth of the oil pump gears: 0.001–0.003 mm
7. Use a metal ruler and feeler gauge to measure the lateral clearance of the oil pump gears.
Maximum permissible lateral clearance of oil pump rotors: 0.04–0.06 mm

Installation
Oil pump
1. Install the outer and inner gears of the oil pump into the front cover, having first aligned the marks applied earlier.
2. Install the oil pump cover and secure it with bolts. After tightening the bolts, make sure the gears turn easily and smoothly.
Tightening torque: 8–12 Nm
3. Install the relief valve, spring and screw the plug in, tightening it to the required torque. Before installation, lubricate the relief valve with engine oil.
Tightening torque: 40–50 Nm
Front Oil Seal Ring
1. Check the front sealing ring for wear or damage to the sealing lips and replace if necessary.
2. Check the condition of the spring ring that compresses the working edges of the sealing ring.
3. Lubricate the outer surface of the new sealing ring with engine oil. Using special tool 09231–22100 or a bushing of the appropriate diameter, install the sealing ring on the crankshaft until it touches the front cover.
4. Using special tool 09231–22000, install the sealing ring into the front cover socket until it stops.
5. Install the crankshaft pulley, timing belt and crankshaft pulley.
6. Install the oil filter.
7. Clean the mating surfaces of the oil pan and cylinder block from any remaining old gasket.
8. Apply a continuous bead of sealant 4 mm in diameter to the mating surface of the oil pan. Around the bolt holes, place the sealant on the inside. After applying the sealant, install the pan no more than 15 minutes later.
9. Install the oil pan onto the cylinder block and secure with bolts.
Tightening torques: 6–8 Nm
