New rollers don't spin freely?
 
I just bought a new BMW deflection roller, and a new belt tensioner for my 2002 330Ci. I noticed that the roller wheels do not spin freely; they are actually pretty tight. Is this normal? The current ones on the car spin like a top, so I assume that they will free up after installation? I am replacing my current ones due to noise from at least one of them currently.

Also, does anyone know the torque specs for attaching these? I can't find any reference in the Bentley manual.

Thanks.

Yes. If they were loose, that would be a worry.

+1 for totally normal

Your current ones are shot; replace all at the same time.

High wear part as they spin at 2X engine speed.

A couple of hours ago I installed 2 new INA mechanical tensioners at 20 lb-ft and the idle pulley at 35 lb-ft.

They do not spin freely, that's a sign of a new roller. Old rollers spin freely when they are old and need to be replaced. New rollers (pulleys) are tight and smooth and do not spin at all.

I believe that the torque value for the mechanical tensioner bolts are 16ft/lbs.

You probably have a hydraulic one...not sure if different spec.
