Front crankshaft oil seal
Removing
1. Remove the timing belt.
2. Remove the crankshaft V-belt pulley.
Pic. 3.34. Crankshaft seals: 1 - torque converter drive plate (AKP); 2 - adapter plate (AKP); 3 - bolt, 93–103 Nm; 4 - bolt, 93–103 Nm; 5 - flywheel assembly (AKP); 6 – a back epiploon of a cranked shaft; 7 – a forward epiploon of a cranked shaft; 8 – a remote ring of a cranked shaft (DOHC); 9 – sensor rotor (DOHC); 10 - key; 11 - crankshaft pulley
3. Remove pulley 11 (pic. 3.34) crankshaft timing belt and key 10.
4. Remove the sensor rotor and crankshaft spacer 8 (DOHC).
5. Drill two small holes in the front crankshaft oil seal located at diametrically opposite ends of the oil seal. Screw two self-tapping screws into the drilled holes in the stuffing box and use pliers to pull out the stuffing box 7 by the screw heads.
6. Clean the gland seat.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
1. Lubricate the entire seal lip with a small amount of engine oil.
Pic. 3.35. Using drifts to install the front crankshaft oil seal: 1 - crankshaft; 2 – mandrel MD998717; 3 - stuffing box
2. Install the gland by lightly tapping the mandrel until it is flush with the gland body (pic. 3.35).
3. Remove all traces of engine oil and install the crankshaft pulley.
Rear crankshaft oil seal
Removing
1. Remove the crankshaft position sensor.
2. Remove the engine oil pan.
3. Remove a transmission in gathering.
4. Remove the clutch cover and clutch disc.
5. Fix the flywheel or torque converter drive plate from turning by installing a special tool on the flywheel ring gear, unscrew the fastening bolts and remove the flywheel or torque converter drive plate and adapter plate 2 (see fig. 3.34).
6. Drill two small holes in the crankshaft rear oil seal located at diametrically opposite ends of the oil seal. Screw two self-tapping screws into the drilled holes in the stuffing box and use pliers to pull out the stuffing box 6 by the screw heads.
7. Clean the gland seat.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
1. Lubricate the entire seal lip with a small amount of engine oil.
Pic. 3.36. Using drifts to install the crankshaft rear oil seal: 1 – a back epiploon of a cranked shaft; 2 – mandrel MD990938; 3 – mandrel MD998776; 4 - crankshaft
2. Install the stuffing box by pressing it in so that the end face is at the level of the chamfer of the stuffing box housing (pic. 3.36).
3. Before installation, clean the bolts, threaded holes in the crankshaft and flywheel from oil, sealant and other contaminants (ITUC) or torque converter drive plate (AKP).
Pic. 3.37. Places for applying sealant and lubrication when installing the crankshaft rear oil seal: A - manual transmission; B - automatic transmission; 1 - crankshaft; 2 - places for applying sealant ZM STUD Locking 4170 or similar; 3 - flywheel; 4 - places for applying engine oil under the bolt washer; 5 - drive plate
4. Lubricate with oil the contact surfaces of the flywheel mounting bolts (ITUC) or torque converter drive plates (AKP) (pic. 3.37).
5. Apply engine oil to the flywheel holes.
6. Apply 3M STUD Locking 4170 or equivalent to the threads of the mounting bolt holes (see fig. 3.37).
7. Using a special tool, as when removing, fix the flywheel or torque converter drive plate and tighten the mounting bolts to a torque of 93–103 Nm.
