<center><img src="http://cascadecrew.org/John/Audi12.jpg"></center><p>In the middle of fixing my blown head gasket, and messed up cyl. head. I was re-installing my cam sproket on the my 1990 7A. I appeared that the keyway has broken off. I quick look in ETKA shows this should be a woodruff key. The keyway does not show as being cast into to the sprocket (the part number on my sprocket matches what ETKA shows)

Has anyone run across a cam sprocket with cast in keyway, instead of the woodruff key?

(I attached the pick of my sprocket, at what appears to be a sheered keyway.)

Thanks,
John

Also broken. Called Chris at Force5 and had a new one two days later, with key intact, also cast in.

HTH!

This was also confirmed to me by Scott at SJM Autotechnik, he said it looks like a misprint in ETKA.

It is sold for such uses as repairing keyways. I think I have the brand name right, my local Mill Supply store has several different cans on the counter. No experience with it myself.

For $50, I'm just going to order a new one. I would rather sleep well knowing the cam gear is new. Last thing I want, is to spend all this time and money on the motor, just to start it up, and end up bending some valves.

All the key does is locate the gear until you've torqued the bolt down. With no/not enough torque on that bolt, relying on that key doesn't seem like that smart a thing to do.

Same thing with the crank timing gear, tiny key, both were broken on my 200q20v avant when I got it with bent valves.

It's the same as a 16V VW, and adjsutable gears are available for just over $100.
