Removal the oil seal
Remove the poly V-belt.
Remove the timing belt
Fig. 2.138. Fixing the crankshaft sprocket
Remove the crankshaft sprocket. To do this, secure the crankshaft gear with a counter support (fig. 2.138).
Fig. 2.139. Installing the central bolt
To insert the oil seal puller, screw the central bolt into the crankshaft until it stops by hand (fig. 2.139).
Unscrew the inner part of the seal puller nine turns (about 20 mm) from the outer part and secure with a knurled bolt.
Lubricate the threaded head of the puller with engine oil, install it and, pressing hard, screw it as deep as possible into the seal.
Fig. 2.140. Turning the inner part of the puller
Loosen the knurled bolt and rotate the inside of the puller against the crankshaft until the seal is pulled out (fig. 2.140).
Installing the seal
Remove any remaining oil from the crankshaft journal using a clean rag.
Fig. 2.141. Installing the guide bushing
Install the guide sleeve onto the crankshaft connecting rod journal (fig. 2.141).
Place the dry seal through the guide sleeve onto the crankshaft journal.
Fig. 2.142. Pressing in the oil seal
Press the seal in using the mounting tool and bolt (M16x1,5x60) to the limit (fig. 2.142).
Install the crankshaft gear and secure it with a counter support (fig. 2.138).
Note: There should be no oil on the mating surfaces between the timing belt drive gear and the crankshaft.
Note: The center bolt should be replaced.
(View the original on this resource vwmanual)
Note: The threads and flange must be free of oil and grease.
Tighten the new bolt to 90 Nm and turn it an additional 90° (1/4 turn) (turning can be carried out in several stages).
Further installation and assembly is carried out in the reverse order of removal.
