I keep breaking the OE 'plastic' PS pulley.
Does anyone know for any stronger metal PS pulleys available? If not I will look into getting one made / machined. Would steel be the choice over aluminum? Aluminum may spin on the shaft it's pressed onto? (I think aluminum absorbs heat faster, and as it becomes hot could it perhaps expand at a faster rate than the steel shaft?) Or would the extra weight of a steel pulley affect how it spins up / more load? Any engineers out there able to comment? Thanks.
This is not just a SC issue, 3 other members in the UK (NA) have had the OE pulley bust now.
