Caution! When replacing the vibration damper, do not damage the engine cooling system radiator.
The torsional vibration damper must be replaced in the following order, prepare the tools "11.2.170", "11.8.190", "11.8.200" and "11.8.210". Lock the flywheel (drive disk) using the device "11.2.170" or its analogue.
Device 11.2.170
Remove the engine compartment protective cover. Remove the fan drive coupling with the impeller and fan cover. Remove the air conditioning compressor and generator drive belt.
The torsional vibration damper has two design options: fixed to the hub with bolts, option No.1, and connected to the hub through clamps and fixed to it with a central bolt, option No.2. When it is removed, the flywheel is not blocked.
OPTION #1
Loosen the bolts (arrows, Fig. 3.96) and remove the torsional vibration damper.
When installing the damper, align the centering hole on it with the centering pin (1). Insert the bolts (M8) and tighten them crosswise to a torque of 22 N·m (2.2 kgf·m).
Attention! Prevent damage to the side member by placing a wooden block under the device "11.8.190".
Device 11.8.190
When removing the vibration damper in version No.2, the flywheel does not need to be blocked. Assemble the "11.8.190" device with the "11.8.200" and fix it in the cutouts of the vibration damper.
Adaptation 11.8.200
Install the device "11.8.190" into the cutouts of the damper. Turn the device to the left so that it is fixed in the damper. Loosen and unscrew the central bolt (1, Fig. 3.97) with a washer and remove the damper.
When loosening and tightening the central bolt, it is necessary to hold the device "11.8.190" from moving with an assistant or rest it on the front side member if it is free.
Before installing the torsional vibration damper, the prismatic key should be checked (11, see Fig. 3.10) for the absence of damage and correct installation.
1 - bolt; 2 - spacer washer; 3 - damper; 4 - star; 5, 10 - bearing shell; 6, 9 - thrust bearing shell; 7 - toothed wheel; 8 - lock bolt; 11 - key; 12 - shaft mark
Replace the front crankshaft oil seal and the central bolt, installing it with a washer, tightening it by hand. Using the device "11.8.190", tighten the central bolt to a torque of 410 N·m (41.0 kgf·m).
