Because I can remove my intake manifold in 3-4 minutes, I may have you beat on time to change the water pump... If thin OEM pulleys are so difficult to work with, I'd recommend pressing a Volvo flange onto the shaft and bolting on either Darryl Tinnerstet's pulley or a Volvo steel one with the outer belt groove filed or ground off (to prevent interference with the A/C belt). Volvo flange is at least 1/2" thick -- presses on & off no problem, no heat necessary. Advance computer shows a flange already pressed on their replacement pump.
