If you are working on your main caps, then you are in an engine rebuilding situation. If they actually broke, you need to find out why, and replace or repair the parts, including the crankshaft, that are bad. If, by breaking, you simply mean that you loosened the bolts, you still need to evaluate the status of the crankshaft and bearings. This involves checking for size, remachining as necessary, replacing parts as necessary, checking bearing clearance, and torquing the cap bolts to specification.

Do you need to mark main caps when removing?
Yes. You want to make sure they are put back in the same location and in the same orientation. They may look alike, but understand that the main caps were "align bored" to make a straight path for the crankshaft to ride. There could be a couple thousandths of an inch difference between two adjacent main caps, so you should definitely put them back where they came from.
