– Remove the bolts -1 through 6-.
– Remove sealing flange.
Installing

Note

♦

Be sure to check the expiration date of the silicone sealant.

♦

The sealing flange must be installed within 5 minutes after ap‐

plication of Silicone Sealant.

♦

To prevent contamination of the lubricating system with seal‐

ant residue, place a clean cloth over the open components of

the oil pan.

CAUTION

Risk of injuring the eyes from sealant residue.
– Wear protective eyewear.

– Remove remaining sealant on the cylinder head with a flat

blade scraper or with a rotating plastic brush.

– Sealing surfaces must be free of oil and grease.

– Cut the tube nozzle at the front marking (nozzle diameter: ap‐

proximately 2 mm).

– Apply silicone sealant as illustrated to the clean sealing sur‐

face of the sealing flange.

♦ Sealant bead thickness: 2 to 3 mm.

Note

♦

The sealing flange must be installed within five minutes after

application of silicon sealant.

♦

The sealant bead may not be thicker than specified, otherwise

excess sealant could enter the oil pan and clog the oil intake

tube.

– Position the Seal Installer - Sealing Flange Guide Sleeve -

T20097- on the crankshaft pins -A-.

– Lightly coat the seal with engine oil.
– Slide the sealing flange onto the crankshaft pins with the Seal

Installer - Sealing Flange Guide Sleeve - T20097- .

– Tighten the new bolts in evenly in the sequence shown:

Note

♦

Only six bolts are installed, two bolt openings remain open.

♦

After installing sealing flange, the sealant must dry for approx‐

imately 30 minutes. Only after then may the engine oil be

replenished.

Assemble in reverse order of disassembly.
