Removal Procedure
Start By:
Remove the Alternator belt. Refer to Disassembly and Assembly, "Alternator Belt - Remove and Install".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g01249049
Use a suitable tool in order to prevent the crankshaft from rotating. Remove bolts (1).
Remove thrust block (2).
Carefully remove the assembly of the crankshaft pulley from the crankshaft.
Follow Steps 4.a through 4.b in order to disassemble the crankshaft pulley.
Remove bolts (5).
Remove crankshaft pulley (4) from crankshaft adapter (3). Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Ensure that the crankshaft adapter, the pulley and the thrust block are clean and free from damage. Replace any components that are damaged. It is possible to reclaim a crankshaft adapter with a worn seal surface by installing a wear sleeve. Refer to Disassembly and Assembly, "Crankshaft Wear Sleeve (Front) - Remove and Install".

If necessary, follow Steps 2.a through 2.b in order to assemble the crankshaft pulley.
Install crankshaft pulley (4) to crankshaft adapter (3).
Install bolts (5) to the assembly of the crankshaft pulley, and the crankshaft adapter. The bolts should be evenly spaced.
Tighten the bolts to a torque of 78 N m (58 lb ft).
Ensure that the front of the crankshaft is clean and free from damage. Install the assembly of the crankshaft pulley to the crankshaft.
Illustration 3 g01390496
Align the holes in thrust block (2) with the holes in the crankshaft. Note: Ensure chamfered holes (X) in thrust block (2). Face toward the front of the engine.
Install thrust block (2) to the assembly of the crankshaft pulley.
Install bolts (1) to thrust block (2).
Use a suitable tool in order to prevent the crankshaft from rotating. Tighten the bolts evenly to a torque of 115 N m (85 lb ft).
Repeat Step 7 one more times in order to ensure correct torque. End By:
Install the alternator belt. Refer to Disassembly and Assembly, "Alternator Belt - Remove and Install".
