The gland is made of PTFE material. Before installing the oil seal, it is forbidden to lubricate its working edge and camshaft.
1. Remove the camshaft drive belt (see subsection 2.4.1).
2. Holding the camshaft from turning, unscrew the fastening bolts 1 and remove the camshaft pulley 2 (3 - gear sector).
3. Loosen the bolt 1 securing the camshaft pulley hub by two turns, while holding the shaft from turning. At service stations, for this purpose, the device T 10051 is used (2 - hub; 3 - adaptation T 10051).
4. Using a puller 1, slide the hub 2 off the camshaft cone. Then remove the puller, unscrew the hub mounting bolt and remove the camshaft pulley hub.
5. Take out the seal. At service stations, a T 30003 O-ring puller is used for this.
6. Wipe the camshaft thoroughly to remove oil and dirt. In order not to damage the working edge of the oil seal, seal the groove on the camshaft cone with tape.
7. Carefully slide the new oil seal onto the camshaft and press it in with a suitable mandrel until it stops.
8. Install the pulley hub and tighten its fastening bolt to 100 Nm.
4. Using a puller 1, slide the hub 2 off the camshaft cone. Then remove the puller, unscrew the hub mounting bolt and remove the camshaft pulley hub.
9. Put the camshaft pulley on the hub, while the gear sector 3 (see above) should be at the top. Screw manually bolts 1 of fastening of a pulley.
10. Install the camshaft drive belt and adjust it.
