– 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.
