Vibration Damper, Removing And Installing

Special tools and workshop equipment required 

• Counterhold - Vibration Damper: T10355 
• Vibration Damper Assembly Tool: T10531 

Individual components of the Vibration Damper Assembly Tool: T10531  :

• Vibration Damper Assembly Tool - Counterhold Tool: T10531/1 
• Vibration Damper Assembly Tool - Tensioning Pins: T10531/2 
• Vibration Damper Assembly Tool - Turning Over Tool: T10531/3 
• Vibration Damper Assembly Tool - Knurled Nut: T10531/4 

The vibration damper bolt -A- connects the vibration damper -1-, the timing chain sprocket -2- and the crankshaft -3- with each other. Secure the chain sprocket as described as follows to the crankshaft, before removing the vibration damper.

Vibration Damper, Removing: 

-- Remove the right wheel housing liner front section. Refer to FRONT WHEEL HOUSING LINER, REMOVING AND INSTALLING .

-- Remove the ribbed belt. Refer to RIBBED BELT, REMOVING AND INSTALLING .

-- Remove the : T10060A  from the ribbed belt tensioner.

-- Turn the vibration damper to TDC -arrow- using the : T10355  .

• The notch on the vibration damper must align with the arrow marking on the lower timing chain cover.
• The marking on the cover is located in the >>four-o'clock position<<.

-- Loosen the vibration damper bolt approximately ¹ /₂ turn by using the : T10355  .

-- If the vibration damper was turned, correct to TDC.

-- Remove the bolts -arrows- for the timing chain cover. The bolts must be replaced.

-- Place the : T10531/1  as shown on the vibration damper and tighten it hand-tight using the knurled bolts -arrows-.

-- Remove the vibration damper bolt completely.

-- Check if the : T10531/3  -A- can be easily pushed over the clamping piece -B-. If necessary turn the adjusting bolt -arrow-.

-- Install the : T10531/2  in the crankshaft and tighten it hand-tight using a 12 mm open end wrench -A-.

-- Tighten the adjusting bolt -A- hand-tight, to secure the chain sprocket to the crankshaft.

-- Remove the knurled bolts -arrows-. Remove the : T10531/1  and vibration damper -A-.

If the Crankshaft is Turned without the Vibration Damper:

-- Place the : T10531/3  -A- on the tensioning pins and while doing so pay attention to the chain sprocket tooth contour. The flat side of the tool is at the top in TDC.

-- Tighten the : T10531/3  with the : T10531/4  -B-.

-- The crankshaft can now be turned at the hex fitting -arrow-.

Vibration Damper, Installing:

-- If necessary, remove the : T10531/4  -B- and the : T10531/3  -A- from the tensioning pin.

-- Attach the vibration damper in TDC. While doing so, pay attention to the tooth contour of the chain sprocket -arrow-.

-- Place the : T10531/3  -A- on the tensioning pins the at the same time the hex fitting points to the vibration damper.

-- Install the : T10531/4  -B-, while doing this move the vibration damper slightly back and forth, to check in the vibration damper is seated correctly in the tooth contour. Tighten the collar nut until the vibration damper can no longer be turned.

-- Place the : T10531/1  as shown on the vibration damper and tighten hand-tight using the knurled bolt -arrows-.

-- Remove the : T10531/4  -A- and loosen the adjusting bolt -B-.

-- Remove the : T10531/2  with the : T10531/3  .

-- Install a new vibration damper bolt hand-tight with an oiled O-ring -1-.

-- Remove the knurled bolts -arrows- and remove the : T10531/1  .

-- Tighten the vibration damper bolt using the : T10355  .

-- Install the new bolts -arrows-.

Further assembly is performed in the reverse order of the removal.
