Removing
- Remove ribbed belt.
- Remove camshaft drive belt.





- Remove crankshaft toothed belt sprocket by counterholding sprocket with 3415.
- Drain engine oil.
- Remove oil pan.
- Unbolt front sealing flange.
- Remove sealing flange, release using light blows with a rubber hammer if necessary.

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 approximately 3 mm, or 1/8 inch)
- Cover sealing surface of oil seal with a clean cloth before applying sealant.

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

- Apply silicone sealing compound, as shown, to clean oil pan sealing surface. Sealing compound bead must be:
^ Thickness of sealant bead -arrows-: 2 to 3 mm (3/32 to 1/8 inch)
^ Apply continuous bead of sealant, passing inside of bolt holes in oil pan -arrows-.





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

Only oil seals with annular spring

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

Only PTFE oil seals

Note: Use guide sleeve T10053/1 to install sealing flange with oil seal already installed.

Continued for all oil seals
- Tighten sealing flange securing bolts using alternate sequence.
