Replacing the oil seal on the intake camshaft is done in a similar manner.
Dismantling
1. Disconnect the negative battery terminal.
2. Remove the lower engine guard.
EXTERIOR PARTS, REPAIR WORK, Lower engine protection shield.
3. Unscrew the 3 bolts securing the right mudguard panel and remove the panel.
4. Remove the hydraulic support.
ENGINE - MODIFICATION K, volume 1.8, Front exhaust camshaft oil seal, Right engine hydraulic support.
5. Remove the upper part of the timing belt cover.

6. Rotate the crankshaft until the marks on the camshaft gears align.
7. Remove and discard the timing belt tensioner mounting bolt.
8. Remove the spring indicator together with the timing belt tensioner.
9. When removing the timing belt from the camshaft gears, do not use any tools (hands only). CAUTION: Check the belt for wear and contamination. Replace the belt if it is worn or contaminated.
10. Remove the LRT-12-134 camshaft alignment tool.
11. Hold the camshaft with the LRT-12-182 fork and unscrew the camshaft gear mounting bolt with the washer.
12. Remove the camshaft gear.
13. Lay out a rag to collect any leaking oil.
14. Screw the timing gear mounting bolt into the camshaft.
15. Remove the camshaft oil seal using the LRT-12-147 puller and the LRT-12-129 bolt.
16. Discard the camshaft oil seal.
17. Remove the bolt from the camshaft.
Installation
1. Wash the oil seal seat and camshaft.
2. Check that the protective boot LRT-12-203 for installing oil seals is clean. Install the boot on the camshaft.
3. Install the oil seal using the LRT-12-148A tool.
NOTE: Front seals are black in color.
CAUTION: Seals must be installed dry. Do not use the LRT-12-148 tool.
4. Clean the camshaft gear and the seat on the camshaft.
ATTENTION: If the gears manufactured by sintering (powder metallurgy technology) have been in contact with oil for a long time, they must be soaked in a solvent and then washed in a clean solvent before installation. The porous structure of the sintered material absorbs oil, which, when released, will contaminate the timing belt.
5. Install the toothed wheel on the camshaft, screw in the bolt with the washer. Fix the camshaft with the LRT-12-182 fork and tighten the bolt to 65 Nm.
6. Align the camshaft marks and install the LRT-12-134 drift.
7. Position the spring indicator so that it is above the bolt on the right and so that the tensioner lever is at the 9 o'clock position.
8. Screw in the new special one and tighten it just enough so that the tensioner lever can just barely be moved.
9. Put on the timing belt without using tools (only by hand). During installation of the belt, its branch between the toothed wheels of the intake and exhaust camshafts must remain taut.
10. Check that the belt is completely on all gears and rollers.
11. Remove the LRT-12-134 camshaft alignment tool.
12. Using a 6 mm Allen key, turn the tensioner counterclockwise until the tensioner pointer is opposite the spring indicator. The tensioner pointer should approach the spring indicator from above. If the tensioner pointer passes the spring indicator, you must completely retract the tensioner and repeat the operation.
NOTE: If installing an old belt, the spring indicator must be aligned with the bottom edge of the pointer.
13. After checking the correct position of the pointer relative to the indicator, tighten the bolt to a torque of 25 Nm.

14. Turn the crankshaft 2 revolutions until the marks on the camshaft gears align.
Do not rotate the crankshaft by the camshaft gears, camshaft mounting bolts or timing belt.
15. Check that the tensioner pointer is positioned correctly relative to the indicator.
16. If the position needs to be corrected, loosen the tensioner mounting bolt enough so that the lever can be moved with greater force. Turn the lever clockwise until the tension on the belt is completely released, then turn the lever clockwise until the pointer is correctly aligned with the indicator.
17. After checking the correct position of the pointer relative to the indicator, tighten the bolt to a torque of 25 Nm.
18. Turn the crankshaft 2 revolutions until the marks on the camshaft gears align.
19. Check the position of the pointer relative to the indicator; if necessary, repeat the operation described above.
20. Install the upper part of the timing belt cover.

21. Install the hydraulic support.
VIGATOR - MODIFICATION K, volume 1.8, Front exhaust camshaft oil seal, Right engine hydraulic support.
22. Install the mudguard panel and secure it with bolts.
23. Reinstall the lower engine guard.

24. Connect the negative battery terminal.
25. Add oil to the gearbox.
