after I installed the upper balance shaft in my 968 (new bearings, spacer and gaskets) I put the pulley on and was able to turn it by hand, but its certainly not free-spinning. It took a fair bit of effort to turn it.
Assembly lube was used, and hardware was torqued to spec.
Is this normal?

For what it's worth, Mine was tight like this, and it turned out fine. I believe similar issues ahve been posted a few times before by others. You are sure you put the correct seal in the upper vs lower right? they are different by like a mm.

There should be little resistance on the gear. Did you put the balance shaft covers on the correct side, the side it came off of? There is a guide pin that holds the bearing half, if you did not get the bearing in correctly that will also cause the problem.

thanks for the responses guys!
I'm not CERTAIN that I put the correct balance shaft cover onto the original side (any way to tell?). The cover with more corrosion was put onto the lower balance shaft.
I am certain that the bearing was seated poperly with respect to the roll-pin.
I am certain that the correct seal was used (yes - the OD on the two seals are different).
Kerry - you suggest removing and re-install?
thanks guys - I really want to do this correct and not have to take it apart. The engine is real easy to work on while its out of the car!

Joe - thanks for the information. You were correct the front cover was out of alignment. Its much better now.
The lower balance shaft was more difficult. After much re-aligning its pretty good. The balance shaft is not quite as free-spinning as the upper one... but its EASILY turned by hand - with no sprocket on the front.
Joe - this is not the first time that you've been extremely helpful. I owe you a beer!

One question,
You used the loctite stuff to seal the housing, right?
If so, did you scrape it off and redo it everytime you readjusted? Just wondering incase I'm ever there.

I did use the loctite.. however - it takes a bit of time to setup (cure)... I maybe spent <30min adjusting therefore I did not have to re-seal each time.
Of course - I had to completely remove the housing to scrape the loctite off from when I originally installed it several days ago.
