Removing a sludge trap plug can be a pain sometimes, especially when the threads are damaged from being peened over. Now can you use this tap to clean your threads before you assemble your sludge trap. We use this same tool here at our shop with great results! Tap measures 7/8" X 20 TPI suited for Triumph 650 and 750 twins as well as many BSA unit twins. I recommend measuring your sludge trap thread pitch and diameter to ensure that this tool will work.
