E9 Power Steering Belt Tension

[TG-2002-320i-328ci]

Does anyone have a good technique for getting the optimal tension on the Power Steering Belt given that the PSP acts as the tensioner itself?

My belt doesn't pass the 90 degree test and I can see some wobble when running (but no noise).

Also - I don't have a second set of hands at the moment!

Thanks

what kind of test is the 90 deg ?
i just drop the pump until i can displace the belt 10mm in the middle of its length using a medium pressure
then i give some torque to those bolts

I use a small wrecking bar on the pulley shaft housing tensioned by my leg in order to free up my hands

You should be able to twist it 1/4 of a turn or 90 degrees as DQ mentioned.
