General information
1. 4-cylinder engines do not have a damper, while 5-cylinder engines have a one-piece damper. The order of removal and installation for both types is the same.
Pulley / crankshaft damper
Removing
2. Disconnect the negative battery terminal.
3. Raise the engine hood as far as it will go as described in chapter 11.
4. Remove the heatsink as described in chapter 3.
5. Remove the accessory drive belt as described in chapter 1B.
6. Turn away and remove bolts of fastening and remove a pulley/damper. If necessary, hold the pulley/damper with a socket or wrench on the hub bolt.
Installation
7. The order of installation is the reverse of the order of removal; also put on the accessory drive belt as described in chapter 1B, and install the heatsink as described in chapter 3.
Hub
Removing
Caution: The hub bolt is very tight. A special tool may be required to hold the hub while loosening the bolt. Do not attempt this job with the wrong or randomly selected tool: injury or damage will result.
Attention: When installing, to ensure the specified in "Technical Data"tightening torque, a torque wrench is required. A puller may be required to remove the hub.
8. Remove the crankshaft pulley/damper as described earlier in this chapter.
9. Prepare the hub holder. A suitable fixture can be made from two strips of steel of different lengths connected by a large screw as an axle. Attach the fixture to the hub using the pulley/damper-to-hub bolts (see fig. 5.9).

10. Using a socket wrench and a suitable extension, loosen the hub mounting bolt. Note that the bolt is tight.
11. Turn out a bolt and remove four spring washers or if it is used. large conical washer.
12. Remove the hub from the crankshaft. If necessary, use an appropriate puller.
Installation
13. Align the hole in the hub with the stud on the crankshaft flange and slide the hub onto the crankshaft.
14. On models that use spring washers, they should be lubricated and then installed with the convex side to the head of the bolt (see fig. 5.14).
Pic. 5.14. The crankshaft pulley/vibration damper hub washers must be installed with the convex side towards the bolt head
15. On models with a conical washer under the head of the hub mounting bolt, install the washer with the larger diameter side facing the hub.
16. Grease a carving and insert a bolt of fastening of a nave.
17. Attach the retainer to the hub in the same way as during removal, then tighten the hub mounting bolt to the correct torque. Do it carefully. to avoid damage and destruction.
18. Install pulley/damper as described higher in this chapter.
