Easiest of all the coaster brake hubs to work on. Can be torn apart from the non drive side with just a 7/8" or adjustable wrench. Better to take apart from the sprocket side with the same wrench and a 3/4 or 19mm cone wrench. Clean everything and regrease with good bicycle or even hi-temp wheel bearing grease. Almost idiot-proof to put back together. Even the bearings are marked so you can't put them in backwards. Adjust so there is just a hint of play at the rim and you're good to go!
