Replacing crankshaft oil seal on the flywheel side
Pulling out sealing flange with a wheel sensor Remove the gearbox. Remove the flywheel. Remove the intermediate plate.
Place the crankshaft in the TDC position of the cylinder as shown in Figure 2.263. Remove the oil pan.
NOTE In order to more clearly display the assembly operations, they are shown at the removed engine. When assembling the engine installed and removed the same transmission. |
| Fig. 2.264. Removing the speed sensor of the motor shaft
|
Remove the mounting bolts of the sealing flange.
NOTE The sealing flange and the wheel sensor is extruded from the crankshaft with three bolts M6x35 mm. |
Screw three bolts M6 x 35 mm threaded holes in the sealing flange (Fig. 2.265). Alternating, screw the (maximum one half turn (180 ?�) for each screw) bolts in the sealing flange and press out it with the wheel of the crankshaft sensor.
Pressing the sealing flange with a wheel sensor
| Fig. 2.266. Mounting device: A - the pressing surface; B - hex nut; C - mounting cup; D - the locking pin; E - Allen screw; F - the guide pin for diesel engines (black leather); G - the guide pin for gasoline engines (red handle)
|
Mounting device is installed in the correct position relative to the crankshaft by the guide pin, which is part of the crankshaft hole (Fig. 2.266).
NOTE Sealing flange with a seal from the support ring has politetrafluoraetilena working edge. This support ring serves as a mounting sleeve, so remove it before installing prohibited. Once out of the box and the wheel flange sensor disconnect, or scroll prohibited. The wheel sensor is mounted in position by locking pin on the mounting device. The sealing flange and a gland is one member, so they can be replaced only with the wheel sensor. |
Install the gland with a wheel sensor on the jig (A) Remove the hex nut in almost clamping surface A spindle.
| Fig. 2.267. Installing the mounting device in a vise
|
Hold the assembly tool for clamping surface A lead screw in a vise (Fig. 2.267). Squeeze mounting cups with down until it rested on the hex nut B. Tighten the hex nut on the spindle so that the inside of the mounting device and mounting cup were on the same level.
Remove the protective clip with a new sealing flange (Fig. 2.268).
NOTE The wheel sensor removed from the sealing flange or scroll prohibited. |
A locking hole in the wheel sensor C must coincide with the mark at the flange (Fig. 2.269). Place the flange face on a clean flat surface.
Squeeze the backup ring working edge A in the direction of the arrow down until it rests on a flat surface (Fig. 2.270).
The upper edge of the wheel sensor and the front edge of the flange should be at the same level (Fig. 2.271).
| Fig. 2.272. Installation of the flange on the mounting device
|
Place the flange face to mounting device so that the locking pin into the hole in the wheels of the sensor (Fig. 2.272).
NOTE Make sure that the flange lies on jig smoothly. |
Push the flange and the support ring in the working edge during tightening three screws knurled And on the surface of the mounting device to the locking pin can not slip out of the hole in the wheel sensor (Fig. 2.273).
NOTE When mounting flange should pay attention to the wheel sensor was fixed in the jig. |
Installing the mounting device with a sealing flange on the crankshaft flange (B) Crankshaft flange must be cleaned of oil and grease. The engine is at TDC cyl. 1. Remove the hexagonal nut B until the end of the lead screw.
Push down on the lead screw assembly tool in the direction of the arrow to lay down in the hex nut on the mounting cup A (Fig. 2.274). Align the mounting cup with the flat side to the junction with the crankcase oil pan.
| Fig. 2.275. Securing the mounting device on the flange of the crankshaft
|
Secure the jig with bolts and hexagon socket A on the flange of the crankshaft (Fig. 2.275).
NOTE Screw the screws with hexagon socket A roughly 5-th the threads in the crankshaft flange. |
| Fig. 2.276. Screwing bolts for adjusting the direction of the sealing flange
|
Screw the two bolts M7 x 35 mm A cylinder block for guiding the sealing flange (Fig. 2.276).
Screwing mounting device to the flange of the crankshaft (C)
Push the mounting cup with his hands in the direction of the arrow to the support ring in the working edge pressed against the crankshaft flange A (Fig. 2.277). Insert the guide pin for diesel engines (black leather) F into the hole of the crankshaft. In this way, the wheel sensor is installed in the final assembly position.
NOTE Guide pin for gasoline engines (red handle) D inserted into the threaded hole of the crankshaft is prohibited. |
By hand tighten the two screws with hexagon socket mounting device. Screw the hex nut E on the lead screw so that it is pressed against the mounting cup C. Pressing the wheel sensor on the crankshaft flange using a mounting device (D)
| Fig. 2.278. Tightening the hexagon nut mounting device
|
Tighten the hex nut mounting device with a torque wrench and nozzle with a torque of 35 Nm (Fig. 2.278).
NOTE After tightening the hex nut to 35 Nm between the cylinder block and the sealing flange has yet to be a small space. |
Check the mounting position of the wheel on the crankshaft sensor (E) Remove the hex nut of E before the end of the lead screw. Unscrew the two screws A from the cylinder. Remove the three screws in the thumb of the sealing flange. Remove the assembly tool. Remove the support ring of the working edge.
The wheel sensor takes the exact mounting position on the crankshaft when the crankshaft flange between A and B has a wheel sensor A distance of 0.5 mm (Fig. 2.279). Attach the caliper to the crankshaft flange.
| Fig. 2.280. Measure the distance between the flange of the crankshaft and the wheel sensor
|
Measure the distance between the flange and the crankshaft sensor and the wheel (Fig. 2.280). And if the distance is insufficient, press-fit wheel sensor deeper. When the distance a is reached, screw the new sealing flange fixing bolts, alternating crosswise with torque 15 Nm. Install the speed sensor and the motor shaft zapotyanite retaining bolt to 5 N ?� m (Fig. 2.264). Install the oil pan. Install intermediate plate. Screw the new flywheel bolts. Zapotyanite fixing bolts with a torque of 60 Nm + 1/4 turn (90 ?�).
