C5 A6 4.2 (AWN)

Understand the cam lock bar and crack lock pin are necessary to do the job right and reset the timing if necessary. Can the rest of the tools be improvised?

Was thinking:

Standard 2 jaw puller for the cam gears
Punches, wire, and allen wrenches in place of all those fancy pins
Homemade something to hold viscous fan pulley
Big sockets to drive new seals
How about the tool for the tensioner pulley? (non-concentric one used to preload the belt)
Anything I missed?

Thanks for the benefit of your experiences.

 

For my 2.7T I had the cam-lock bar and the crank pin were the only specialty tools I used. I have a decent, but not impressive, socket set and I borrowed some of the extra big wrenches. I improvised everything else.

Toughest thing on mine was the viscous fan pulley. I tried a bunch of different things to improvise the chopsticks tool. Almost seriously injured myself with an ill advised "cheater bar" style attempt at holding the pulleyt (bar slipped and spun, just missed hitting me in the dome and whacked the **** outta my forearm). Did some cosmetic damage to the face of the pulley and still didn't get it. Ended up threading 1" nylon tubular webbing through the pulley, tying to the frame and tensioning it down to hold the pulley while I cranked on the nut. Probably not the most elegant solution but it was effective.

 

a three jaw puller will work fine on the gears but would highly reccomend having the right tool for the fan hub as stated above it is a real bear even with the tool it was tight as he## on my car.

 

go to blauparts.com they have a 7-day rental on tool kits for $45 plus $500 deposit

However, you need to purchase a timing belt kit to rent the tools...well worth it.

 

Are you just replacing the TB or are you replacing the cam seals as well? If you are just replacing the TB, no special tools are needed, just mark the cam gears and line up the new belt appropriately. If you are going to replace the cam seals (which it sounds like you are and which is a very good idea), you will want the cam lock tool, but that is the only special tool you will need. You CAN get by without it IF you are very, very careful, but the job is much easier with it. I didn't need the special tool to get the fan pulley off. I just tensioned the serpentine belt and whacked the wrench with a hammer and off it came.

I ended up buying T40005, 3242, and T40009 from eBay and an outfit called El Paso tools. Instead of buying a full kit from Blau or ECS, I pieced it out from Partsgeek, in all name brand components (Conti, Graf, Bilstien, Behr, etc.). The whole shooting match from Partsgeek was only $335 (already had a Conti serpentine belt) vs. $500+ from the other guys. I figured the money saved on components, plus the hundreds of dollars saved on labor, justify the $130 in tools. Hopefully that fan pulley won't be too much of a bugger.

A couple guys from the local Audi club offered to let me borrow theirs, but this way I have the flexibility to do the job when there's time.

I bought cam seals and a crank seal, but I'm not sure I'll replace them unless they are leaking, which doesn't appear to be the case upon inspection behind the cam gear covers. I do plan to loosen the pulleys, like it says in Bentley and most other places, to properly tension the belt and keep the valves in perfect time.

 

Buy all the tools don't rent them You'll need them again that's for sure! I bought Mine from El Paso as well off ebay I think. They're good tools.
