3. REMOVE DRIVE PLATE AND RING GEAR SUB-ASSEMBLY (for CVT)

(a) Using height adjustment attachments and plate lift attachments, place the engine assembly on a flat level surface.

NOTICE:

Using height adjustment attachments and plate lift attachments, keep the engine assembly level.
To prevent the oil pan sub-assembly from deforming, do not place any attachments under the oil pan sub-assembly of the engine assembly.
Using an engine sling device and engine lift, secure the engine assembly before servicing.

(b) Using SST, hold the crankshaft pulley assembly.

SST: 09213-54015

SST: 09330-00021

4. REMOVE FLYWHEEL SUB-ASSEMBLY (for Manual Transaxle)

(a) Using SST, hold the crankshaft pulley assembly.

SST: 09213-54015

SST: 09330-00021

(b) Using a 10 mm hexagon wrench, remove the 8 bolts and flywheel sub-assembly.

5. REMOVE NO. 1 CRANKSHAFT POSITION SENSOR PLATE

(a) Remove the No. 1 crankshaft position sensor plate.

6. REMOVE REAR ENGINE OIL SEAL

(a) Using a knife, cut off the lip of the rear engine oil seal.

*a	Protective Tape
*b	Cut Position

(b) Using a screwdriver, pry out the rear engine oil seal.

NOTICE:

Do not damage the surface of the rear engine oil seal press fit hole or the crankshaft.

HINT:

Tape the screwdriver tip before use.
