2084 tool required

[AUDI COUPE 20V]

hi anyone outthere that could lend me this tool to lock the crank, or know a way of locking it or where i can get the tool from i am in birmingham uk

Go to your local Audi dealership and quote the 2084 number at the parts desk. You will be able to buy your own for about £30

you dont need a locking tool just line the marks up and away you go

No - you *DO* need the crank locking tool in order to remove and fit the big bolt in the crankshaft pulley. Occasionally you will see the off 2084 on eBay - note its NOT suitable for ABY, AAN or ADU engines though - they need the 3256 locking tool.

note this is the way i do it
time it up undo the bolt with a 1inch drive air gun (which i use to undo lorry wheel nuts) done this many times before remove the bottom pulley put the bolt back in and time up again then remove your belt etc etc etc done it many times and the locking tools dont hold the crank properly

[S2 Ant]

Locking tools do work properly, how do you plan on torquing up that bolt without holding it still, cos i use air tools a lot but would by no means be happy with just gunning it up and leaving it at that!

Dealerships arent allowed to sell these tools over the counter, you can try and ask tho, you never know.

3256 also wont fit cars with aircon. BTDT.

I'm aware of the impact air-gun trick, but such a high torque device isn't available to most people. I prefer to treat critical bolts with a little more respect. How do you lock the crank when tightening the bolt - I'm assuming you torque it properly and just don't whazz that airgun onto it ?

2084 doesn't lock the AAN, ABY & ADU cranks properly - 3256 is required.
2084 locks the 10V, RR and 3B cranks pretty well in my experience...

Spooky bit of parallel thinking there Ant...

Isn't the clearance issue with the 3256 on aircon cars easily worked around by moving the compressor out of the way - no need to disconnect aircon pipes IIRC !!!!!

No, because the problem is that even with the compressor out of the way (as i done this) it doesnt reach properly to bolt in to place because its a pulley too far away. it will go in to the crank pulley ok, but it bolts in to the hole that the compressor is fitted to and that isnt long enough.... you could extend the bolt, but its designed so that that arm also rests against the block, i wouldnt trust just the bolt to those torques, as once its bent i wouldnt fancy getting it undone again!

[DJones]

My front pulley has been significantly lightened and now does not have the correct centre for the tool to lock on to, how would you hold it?

A few years ago, my mate did the wheel bearings on his Ren 19 16v with an air gun, a week later he bought a complete set of cv joints as this had stripped the threads on them all. I know its not the same, but they are not a calibrated tool, they are the socket equivalent of the "daisy cutter" bomb. When used instead of a torque wrench they are dangerous.
Be careful with them.

[Corey]

I do not like the 3256 as you have to lock the engine 180 deg out undue the bolt then line the marks up.
I cannot believe that this is the documented procedure from Audi also for the 3256!!!
You can use the 2084 on the AAN engine but you need to have the front support bracket from a 90 to use the 2084.
I have modified my 3256 so I can lock the engine in the correct place.

[mcandmar]

Please explain

I have an ABY (AC version) and the 3256 tool in my garage, was trying to work out a solution instead of a very long bolt. I agree with Ant i can see the bolt just bending if i try to torque it up that high. I noticed it does rest against the idler pulley but i doubt that would take the load. Any wisdom greatly appreciated..

Also can anybody tell me how to undo the nut with the engine out of the car? I have it mounted on an engine stand but i'm starting to think i might have to strap that to the wall to stop it falling over

2084 tool

i have accsess to a 3/4 air gun that should tighten the bolt up quite good enogh dont you think also with some lock thread?

BTDT a couple of months ago before i left the country, i made my own locking tool, it should fit all the engine variants, with or without air-con, definately fits RR/3B/and ABY with a/c. I dont have any pics but basically its a 3ft long 1/2 inch thick steel plate with a round boss welded on the end with a deep cutout to locate in the pulley.
I had the end sat on some old wheels (in the 9 o-clock position so to speak) so i could put the pressure down onto the wheels not through the stand, worked a treat.
