Just realized something doesn't jive from the parts listing, that 20-3515-1 flywheel is actually as measured 27mm Diameter and 13mm Thick.
More like this one
or
not the one in the parts listing. https://www.mthpartsandsales.c...lists/297?type=lists
Not these, not for this PS3 model.
Edit, to be clear, I'm not saying my 27mm diameter vs 26.85mm is the "mistake", I'm saying that the PS3 Pittman bracket is used with a 26.8(5)mm Diameter flywheel and the parts listings- there may be more- might need to reflect that. A 30mm flywheel is too large for that bracket and will interfere.
