Re-building air ratchets

Other than what you can find on the internet, I don't have access to any more info on the Snappy air tools. They have their own designs and parts that don't interchange with the rest of the world. You might be better off contacting a Snap On dealer. You may take your air ratchets apart and find nothing broken but they still don't work. Rebuild kits or head repair kits may or may not take care of the problem.
