CYLINDER GP-BOOM 4I8838 - Caterpillar

1. Remove the alternator belt. See Remove Alternator if additional information is required.
If the spacer is not used, damage to the bolt thread can be the result.
2. Remove hub retaining bolt (1) and washer (3) from the end of the crankshaft. Install a spacer (2), washer (3) and bolt (1) on the crankshaft. The spacer is installed behind the washer to get approximately 3.18 mm (.125 in.) of clearance between washer (3) and pulley (4). 3. Install tooling (A), and loosen the pulley from the crankshaft.4. Remove tooling (A).5. Remove the bolt, washer, spacer and crankshaft pulley from the crankshaft.Install Crankshaft Pulley (3304)
1. Install crankshaft pulley (1) on the crankshaft. Install washer (2) with the maximum flat area next to the crankshaft.2. Install bolt (3), and tighten it to a torque of 284 to 340 N m (210 to 250 lb.ft.). Hit the bolt with a hammer, and tighten it again to a torque of 284 to 340 N m (210 to 250 lb.ft.).3. Install alternator belt (4). See Install Alternator if additional information is required.Remove Crankshaft Vibration Damper And Pulley (3306)
Typical Example1. Remove the alternator belt. See Remove Alternator if additional information is required.2. Remove bolt (1) and washer (2) from the crankshaft. Put enough spacers (4) on the bolt to get approximately 3.18 mm (.125 in.) of clearance between washer (2) and vibration damper and pulley assembly (3). Install bolt (1), washer (2), and spacers (4).
Typical Example
If spacers (4) are not used, damage to the bolt and/or crankshaft can result when the vibration damper and pulley are removed from the crankshaft.
3. Install tooling (A) as shown, and loosen vibration damper and pulley assembly (3) from the crankshaft.4. Remove tooling (A), bolt (1), washer (2), washer (4) and the vibration damper and pulley assembly from the crankshaft. If necessary, remove the bolts and vibration damper from the pulley. Inspect the vibration damper housing for leakage or dents (damage housing). If either condition exists, a replacement of the vibration damper must be made.Install Crankshaft Vibration Damper And Pulley (3306)
1. Put the vibration damper in position on the pulley, and install the bolts that hold it.
Typical Example2. Put vibration damper and pulley assembly (1) in position on the crankshaft, and install washer (2) with the maximum flat area against the vibration damper and pulley assemby.3. Install bolt (3), and tighten it to a torque of 284 to 340 N m (210 to 250 lb.ft.). Hit the bolt with a hammer, and tighten the bolt again to a torque of 284 to 340 N m (210 to 250 lb.ft.).4. Install the alternator belt. See Install Alternator if additional information is required.
