Default Dangers at Oil pump housing

Such a stupid design!! I have to get the 740 alt belt done `v8volvo style` this week. It`s getting a Gates XL 7300 belt. 9.5-10mm wide, 780mm long. A bit wider than stock, and a bit longer than stock Volvo #966894 (9.5 x 750La) d24t belt which is discontinued. Cross reference charts at Napa shop made me buy the Gates belt (2x, in case it screws up on the road). I expect my regular belt-squeaking issues and sudden voltage drops go away. (belt slips at electric loads---i guess it`s also not tight enough)

Anyone knows the torque spec on that bolt?
