I have a maple tree that lost a big limb and split a portion of the trunk. After cutting off the limb I want to repair the split. How do I do this to save the tree?

You were right in cutting off the split limb but there's not much you can do to repair a split in the trunk. Trees normally compartmentalize damage and seal it off from the inside. You won't see the calloused tissue where the damage is sealed but a healthy tree will do this all on its own. Don't dress the wound with anything. Dressings just slow the healing process. As long as your tree was healthy prior to the damage, it will recover on its own without any assistance. I'd try to prune or cut away any ragged or splintered areas to make it as smooth as possible to keep water from pooling or insects from collecting in the area. Best wishes with your maple!
