You mean the little 6mm bolts on the pullies, or the big jesus nut on the crank? A 6mm bolt into steel, I'd do at 7ftlbs with some blue locktite. 8mm do 17ftlbs with blue locktite. The jesus nut is an ass-kicker. I don't recall the exact figure for torque, but it's >200ftlbs. If you are unable to get it quite so tight you'll probably be ok. Get some blue locktite on it and at least get it over 150ftlbs or so.
