Crankshaft pulley / vibration damper
Removing
Using a special tool to prevent the hub from turning
1. Remove the ground wire from the battery.
2. Open the hood and lock it in an upright position.
3. Remove the radiator fan impeller and hydraulic clutch.
4. Loosen the radiator fan pulley bolts.
5. Remove the auxiliary drive belt.
6. To prevent damage to the radiator and increase the working space, remove the radiator or, in extreme cases, install a sheet of cardboard on the inside of the radiator.
7. Remove the radiator fan pulley bolts and remove the pulley.
8. Lock the crankshaft pulley/vibration damper from turning using the special tool screwed onto the crankshaft pulley (see fig. Using a special tool to prevent the hub from turning).
9. Unscrew the bolts and remove the crankshaft pulley / vibration damper.
Installation
1. Installation is made in sequence, return to removal.
Hub
Attention! When tightening the hub bolt, use a torque wrench with a tightening torque of 400 Nm. A puller must be used to remove the hub from the crankshaft.
Removing
1. Remove the crankshaft pulley/vibration damper.
2. Secure the hub against rotation using the special tool screwed onto the hub.
3. Unscrew the hub mounting bolt and remove it along with four spring washers or a large conical washer.
4. Using a puller, remove the hub from the front end of the crankshaft.
5. Remove the key from the crankshaft groove.
Installation
The location of the cup washers on the hub bolt
1. Install the keyway into the groove of the crankshaft.
2. Align the groove on the hub with the key and install the hub on the crankshaft.
3. On models with Belleville spring washers, lubricate the spring washers and install them on the bolt with the convex side towards the head of the bolt (see fig. The location of the cup washers on the hub bolt).
4. On models with a conical washer, install the washer on the larger diameter bolt to the hub.
5. Lubricate the threads of the mounting bolt.
6. Using a special tool, fix the hub from turning and tighten the hub bolt to the required torque.
7. Install the crankshaft/vibration damper pulley.
