I read all the messages related to replacing crankshaft seal. But still could not get the center bolt off. Right now the sprocket is on, so is the center bolt. Here is what I did:
1. Took off the pulley damper
2. Use 12 point, 24mm socket with 19 inch breaker bar, turned CCW. No luck
3. Add long (4 feet) pipe. No luck.

I had the timing bit tool kit from blauparts when i tried these things.

I noticed there is "pin" on the crankshaft sprocket. Do i need to pinch it down? I remember searing someone mentioned using a allen wrench and puch it in or out?

Next thing I planned is use a impact wrench and give it a try.

Did I do anything wrong? Or did I missed anything?

Thanks

Checked Bentley manual... the "pin" is actually for aligning the vibration damper with the toothed belt sprocket.

Audi Logic

to keep the crank from turning, it goes where the crank position sensor is mounted

My problem is, no matter what I did, I couldn't get the center bolt loose.

There are 8 socket head hex bolts holding the damper/pulley on. Make absolutely sure you have real good rachet mount socket head hex tools. Don't even think of trying to use an "L head allen wrench"

Next take something sharp and scrape out inside the hex sockets of the bolts, spray them blow them out with air, but get all the crap and rust out. Then take a really good, sharp socket hex tool and seat it into the hex bolt by whacking it in to make sure you are all the way to the bottom.

When you get them all out and are ready to put it back, go to a good industrial bolt and nut place and get brand new bolts. The reason you are doing all this is because you are likely to round out the hex bolt, then you'll be in deep ****. When you buy new bolts you are insuring the next guy who does the job won't round them out.

By the way, the nut on the end of the crankshaft is not a nut. It is part of he crankshaft. If the TDC is in place, it will never turn unless you break the pin.

Finally got the center bolt off.
Audijim113, I am pretty sure the center bolt can be removed. I ordered a new one from the dealer this am before i took the old one off. Are you refferring to other models? Mine is 1994 100.

Thanks
