When changing cambelt, may I suggest you also fit new crank pulley

[Billman]

oh no, my mechanist has tighten the Crank bolt with a compressor tool, but dont know how much torque it makes!

But did this bolt makes so much work? 200 NM instead of 450 and then the pulley key brakes? It dont seem so right to me!

[audiman]

it is right, trust me, i have seen the results.

That bolt is very important! If the correct working procedures arent followed then it ends in tears.

Genuine Audi tool for crank locking isnt too badly priced, however the ABY Crank lock tool WILL NOT FIT IF YOU HAVE AIRCON!
I know from experience!!! Its waiting to go back to them for a refund

3B tool is 27 quid and fits all 3B's

[Billman]

Is it posible that it brakes in the effort of unscrew this bolt? Mine was a fu***ing hard thing to unbolt it!

The Workshop manual for the AAN engine (same in this point with the ABY-ADU says:

Toos Against holder 3256 and tighten tool 2079! What are these?

Screw Torque with the Special "Schwingungsdaempfer"(is the plastic this for the vibrations in front of the Pulley) tool 350 NM

Torque without the special tool for the vibration damper 450 NM !
Screw with gasket seal AMV 188 001 02 tighten

So my question is why so much dufference between those two?

The 3256 is the cranck locking tool, this holds the cranck locked in one postion as you torque the cranckbolt.

The 2079 is an extension tool designed by Audi due to the fact that torque wrenches capable of 450nm is quite rare and expensive ( even worse 15 years ago ). By using this extension tool, torque on the wrench itself is reduced to 350nm. If you use this tool or not doesnt matter as long as the endresult is 450nm at the cranck bolt.

Just to drag up an old thread, can someone confirm the part number for this item is 034 105 263 A

Just trying to make sure i have all the parts im going to need for the garage meet and my Belt change.
Thanks

[MidnightBlueS2]

Out of curiosity, will there be any warning sounds coming from one of the pulleys if they're starting to fail ?

[S2 Ant]

Anyone confirm the part number on this to be 034 105 263A?

I think it is altho its not the easiest item to make out on the diagrams

Not easy ? It's number 5 on the diagram.

It seems your powers are developing but you lack confidence in your results. Follow the daddy and I will show the way :mischeif:

Oh and yes you are quite correct 034 105 263 A is the crank pulley.
