Default Camshaft Locking Tool

00 A4 2.8 ATQ..Is it OK to remove the holding tool during the R&R process, or is there a risk of the cams rotating? And, if they were to rotate, can you just readjust and install the tool to install the belt. Reason I ask, is because there are some videos where the tool is removed, and then the pulleys are popped loose. Then tool is reinstalled. I am just researching prior to performing the belt/water pump replacement. Thanks

Yes it's okay to remove the tool. Just make sure you have your crank lock pin in place. When you do remove the tool the right side pulley may turn a tad clockwise but don't worry just put it back with the tool when you are ready to button things up.

No need to pop the pulleys unless you are doing work under the cam covers.

Here's a good video.

Thanks Huskerbob, I was thinking you had to pop the pulleys so you wouldn't be a tooth off. I guess if everything is lined up to begin with that shouldn't be a problem. Thanks for the video.
I think he has done this job before!

Yes I believe so. He doesn't even use the crank lock or the bar to get things apart just to make sure the cams are lined up for re-assemble.

You can't be off a tooth. As long as the big holes on the sprocket lobe deals are facing each other and the bar fits on you are timed. Belt position makes no difference.

Do the whole 9 yards as long as you're in there.

Good Luck!

Yeah, I watched it about 25 times before I tackled my first 2.8 timing belt job. (Now if I can find one for my 1.8 I'll be set.)

False. Timing adjustment is a critical part of doing the job right.

You were right...well, half right anyway.

Timing on the 2.8 is infinitely adjustable because the cams are not keyed to the sprockets, thus it is impossible to be "a tooth off".

Free the sprockets. Set the timing. Ignore shortcuts that result in an OK job when you could invest a few more minutes and get a good job.

I disagree. If all you are doing is replacing the timing belt and you are in time prior to the work you will be in time after you replace the belt. Removing the belt and putting a new one on does not change the timing. As long as you have the big holes facing each other and you use the cam lock bar there is no need to pop the sprockets.

And how do you know that you are in time prior to starting it? Do you trust the last person who touched it? And do you assume that XX miles of use didn't change anything?

True...assuming that the new parts and old are 100% identical and are installed exactly the same way. Even notice how much the water pump can be moved when the bolts are finger tight?

True...if the tension is equal all the way around the belt. If you have to cheat even a little, you are off. However, the as I've explained above, the chances of this are very small. Why not just take the extra ten minutes and set the timing correctly?

...and why would you go to all the trouble of doing a belt service yet skip the cam seals?
