Removing

- Remove ribbed belt.
- Remove camshaft drive belt.






- Remove crankshaft toothed belt sprocket by counterholding sprocket with 3415.
- Remove oil pan.
- Unbolt front sealing flange.
- Remove sealing flange (release using light blows from rubber hammer, if necessary).
- Remove sealant remnants on engine block with flat scraper.






- Remove sealant remains on sealing flange with a rotating plastic brush (wear protective goggles).
- Clean sealing surfaces, they must be oil and grease free.

Installing

Note:

^ Check expiration date on sealant before using.
^ Install the sealing flange within 5 minutes of applying the silicone sealant.






- Cut-off tube nozzle at forward mark (nozzle diameter approx. 3 mm, or 1/8 in.)
- Apply silicone sealing compound, as shown, to clean oil pan sealing surface. Sealing compound bead must be:
Continuous, passing inside of bolt holes in oil pan (arrows)
Thickness of sealant bead (arrows): 2 to 3 mm (3/32 to 1/8 in.)

Note:
- The sealing bead must not be thicker than the specification, otherwise excess sealing compound could enter the sump and block the oil suction pipe strainer.






- Apply silicone sealant bead (as shown) to a clean sealing surface on sealing flange.
- Immediately install sealing flange and slightly tighten all bolts.

Note:
- Use guide sleeve from 2080A to install sealing flange with oil seal already installed.

- Tighten sealing flange mounting bolts using alternate sequence.
Tightening torque: 15 Nm (11 ft. lbs.)
- Install oil pan.

Note:
- After installing, allow sealant to dry for approx. 30 minutes before filing with engine oil.






- Install crankshaft toothed belt sprocket and hold with 3415 counter-hold.
Tightening torque: 90 Nm (66 ft. lbs.) + 1/4 turn (90°)
- Install toothed belt and adjust timing = Page 1315.
- Install ribbed belt.

Special tools and equipment






^ VW 558 Flywheel lock adapter
^ M8 X 45 Hex bolt and two M 10 nuts
^ Depth gauge

Drive plate, loosening and tightening






Attach tool VW 558 to drive plate with M8 X 45 hex bolt. Place two M 10 hex nuts between tool and drive plate.
Position of tool VW 558:
A To loosen
B To tighten

Installing drive plate






Locate drive plate and backing plate with recesses -1-.
Install new bolts -3- and tighten.
Tighten torque 30 Nm (22 ftlb).






Check dimension -a- at three points and calculate average.
^ Specifications: 19.5 to 21.1 mm (0.770 to 0.830 in).

Note:
- Measure through a hole in drive plate to machined surface of engine block.

If specification not obtained:






- Remove drive plate again and install shim -2-.
- Again tighten bolts -3-.
Tightening torque 30 Nm (22 ft lb.).
- Tighten bolts to 60 Nm (44 ft lb) + 90° (1/4 turn) (can be done in several stages).
