Tension in a Timing Belt?

Need calculate the tight and slack side tension in a 1:1 ratio timing belt.The input torque on the driven pulley is 116.188 N.m and both pulleys are rotating at 5.375 rpm. The belt is simply for power transmission, it isn't carrying any linear positioners or anything. The center distance is 200mm and pulley diameters are both 63.6mm if it helps. Anyone can do this for me go ahead and drown yourself in good karma.
Thanks but should preload be specified as a property or calculated? sorry never really used belts before...

Looks to me that ignoring belt stretch the tight-side tension would be preload plus torque magnitude / radius = 116.118 newton meters / .0318 meters = 3652 newtons + preload. On the slack side it would be 0 + preload. Since the belt will stretch a bit the load on the slack side will be somewhat less.

Those are 2-1/2 inch pulleys, by the way.

Added: The belt manufacturer should be able to tell you how much preload to use. For automotive-size vee belts I think it's typically 100+ pounds. Since you're using a toothed belt I'd think it could be less than for a straight vee belt, but it has to be enough to keep the belt from jumping teeth on the pulleys.
