Why are my balance shafts misaligned after setting them correctly?

Thanks much, I'll hopefully do it tonight and get the car on the road this week.

Here are the belts side-by-side on a sprocket. This should help people better understand the difference, I do a lot of belt changes the two belts install the exact same way.

So I was able to redo the belts and everything is lined up and after starting the car and letting it run, the balance shafts are still lined up after setting the engine to TDC.

The only issue is the supercharged belt whine now, I need to do some fine adjustments to the idler roller and the tension to make that whine disappear.

I bit the bullet and bought the offset wrench to adjust the roller/tensioner for $19.50, doing it with my adjustable wrench has been driving me crazy.

Almost there!

Whine will never disappear. If the belts are silent, they are not tensioned correctly.

I have done 3 belt changes and numerous retensions and I have never been able to eliminate the whine completely. I have played with that idler roller and the tensioner with all the patience of my advanced years. Learn to love the whine.....

What is an acceptable noise for the BB whine, I think I would be embarrassed driving the car around with the whine, it's loud.

A supercharged 944 Turbo. Maybe a 1st in existence?

Once my offset wrench comes in, I'm hoping to get the tensioner and idler roller dialed in to minimize the whine at least.

The offset wrench should be in by Thursday-Friday, just in time for the weekend.

Received the offset wrench on Thursday and finally got to the car this afternoon. Truth be told, the offset wrench in my case, made the balance belt and idler roller adjustments/torquing 100% easier.

Best $19.50 I have spent on the car.

I digress.

So after I adjusted the tensioner and the idler roller, I started the car and the whine was still there, but after about 3-5 minutes the whine was very subtle, nothing like it was before. I proceeded to re-install the belt covers with some new stainless steel bolts and washers, installed and tensioned new alt and p/s belts, put the afm back in place, double checked my work, cleaned up and wiped down my tools and put them away.

Car is ready to roll again after a long New England winter, finally!
