If the belt is removed the spring loaded sprocket moves. If the hub is spring loaded, mine is. When i pulled the belt the sprockets went to their unsprung position.
Well he will find out one way or the other.
Very interesting. They typically stay at 12:00 and are unsprung for me when I remove the belt.

IPD makes a nice cam gear holding tool that may help you.
On the FCP VIDEO he says. "Something moved so I'll have to redo it."

Some have springs , some dont.

jones is right. At about 14:35 in the video he says something moved but he does not show how to set any spring loaded hub. I'm thoroughly confused. These videos are great but sometimes they leave out very important info. Anyway, this forum works great.

I've got code P0017. Just replaced my camshaft seals and hub o-rings. When I was reinstalling my new timing belt my hubs were not spring loaded like in the IPD video. There was no spring action at all on either one. Not really sure what I did wrong. Maybe my tensioner wasn't set properly. Could that be it? I will keep searching. Thanks.

As mentioned, it depends on the engine. On my non turbo, the exhaust cam gear is spring loaded: when I removed the belt it moved (I think clockwise) by a good tooth or two by itself. I got scared, because the marks where no longer aligned with the belt off. But then when I installed the new belt - which always goes first around the the water pump, crank pulley, then over the tensioner, then over the intake cam gear, and only lastly over the exhaust cam gear, the exhaust cam gear moved back by itself with the belt on, and the marks got realigned. Just don't touch the cam gears when the belt is off (also when removing/installing a belt, care not to rotate them if not using a cam lock tool).
