– 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:
