I contacted Huffy to see where I could get a service manual and couldn't tell me. Huffy isn't the greatest for tech support. Would a service manual exist for a Nel Luzzo beach cruiser? I couldn't get my hub back together correctly. I saw the videos and tutorials and I just couldn't get it right ... It was either too loose where the hub would wobble or too tight where the coaster brake wouldn't turn. I ended up bending the bearing and having to take it to a bike shop. It cost me $20 bucks. I was upset that I could not figure out how to fix a simple mechanism. The video I saw the hub was a bit different than might but I'm sure it is the same concept. I really would like to learn how to put that hub together correctly.
