Replacing the front oil seal
Since August 1983, the design of the front toe of the crankshaft has changed. Turbocharged engines have used a specially designed shaft since the beginning of their production. In this regard, the method of removing the front oil seal has changed.
Remove the V-belt, guards and toothed belt as described in the following chapters.
Remove the V-belt pulley as well as the toothed pulley from the front crankshaft toe. When unscrewing the mounting bolts, it is necessary to turn on the fourth or fifth gear in the gearbox and tighten the parking brake.
To properly use the puller shown in rice. 62, it is necessary to screw tool No. 3083, shown in rice. 86. Then the same operations are performed as during the replacement of the crankshaft oil seal of a 1.3-liter gasoline engine (see chapter 3.7).
To install the oil seal on the engine located in the engine compartment of the car, a special sleeve is provided (a tube). The sequence of actions is given in the description of similar operations for gasoline engines. In the case when the engine is removed from the vehicle, use the special tool Nq 3083 (see fig. 86 and 88). If there are no special tools, the installation of the gland must be done with improvised means with great care.
Replacing the rear oil seal
Remove the gearbox, clutch and flywheel.
To remove the rear oil seal, use the tool shown in rice. 87, or a screwdriver, which must be used with extreme care so as not to damage the socket in the cylinder block.
If the engine is removed, connect the oil seal holder and remove the gasket (fasteners are shown in rice. 209). Knock out the gland from the holder (from the middle out). The gland is installed as follows:
Lubricate the seal with engine oil. Carefully push the gland into the socket, pressing on it around the perimeter. In this case, the working edge cannot be damaged.
Then you should use a special device «2003/1» (see fig. 89) or a self-made round plate, which has a hole in the center for the toe of the crankshaft. Tighten both bolts evenly to install the seal in place.
