Crankshaft pulley / vibration damper
Removing
1. Disconnect the negative battery terminal.
2. Where required, remove the engine shield from below as described in Chapter 11.
3. Remove the heatsink and heatsink fan blades as described in Chapter 3.
4. Loosen the radiator fan pulley bolts, then remove the accessory drive belt as described in Chapter 1A.
5. Turn away bolts and remove a pulley of the fan.
6. Turn away bolts of fastening and remove a pulley / an oscillation damper from a nave. If necessary, keep the pulley from turning with the head of the wrench on the bolt securing the st / tice.
Installation
7. Installation is carried out in the reverse order. Install the accessory drive belt as described in Chapter 1A and install the radiator fan blades and shroud and radiator as described in Chapter 3.
Hub
Removing
Warning: The hub bolt is too tight. When loosening the bolt, a hub locking tool is required. Do not use unintentional and unintended tools for this, as this may result in injury or injury.
Note: A puller may be required to remove the hub. Installation may require a torque wrench that generates torque up to 300 Nm. Note also that the hub must be heated to approximately 50°C to install. A puller may be required to remove the hub.
8. Remove the crankshaft pulley as described earlier in this paragraph.
9. Assemble the hub retainer. You can make a fixture from two metal rods connected with an axial bot. Attach the hub anti-rotation tool with the pulley/vibration damper boots,
10. Using a socket wrench and a long lever, loosen the hub bot. Please note that the bot is tightened very tightly.
11. Turn away a bot of a nave and remove spring washers.
12. Using a suitable puller, remove the hub from the crankshaft.
13. Where provided, remove the key from the crankshaft.
Installation
14. Where provided, install the keyway into the groove on the crankshaft.
15. To put the hub on the crankshaft, it must be heated to a temperature of approximately 50°C.
16. When the hub is heated to the required temperature (it is possible to achieve a positive result by immersing the hub for a while in very hot water), align the groove on the hub with the key on the shaft, and install the hub on the end of the crankshaft.
17. Lubricate the spring washers, then install them with the convex sides facing the bolt head (see fig. 5.17).
Pic. 5.17. The convex surface of the washers of the crankshaft pulley hub must face the direction of the bolt head
18. Lubricate the threads of the bots with oil, then install the hub mounting bot.
19. Wrap the hub bot, keeping it from turning with the help of the device. Tighten the hub mounting bot to the required torque. Be careful not to get hurt.
20. Install the crankshaft pulley/vibration damper as described earlier in this paragraph.
