This locknut has a diameter of approximately 44mm. If not is there another tool available?\nThis tool should not work on anything that has to do with a hub. Im guessing you are speaking about the rotor lockring. Those are 44mm x 16 notches, making the BBT-9 and BBT-69.4 the best tools for the job. If you are referring to a different locknut please send an image to tech@parktool.com\nAnswered by Park Tool\nQuestion asked by\nErin\nWill this work with the Shimano EP-600 \/ EP-801 ebike motor?\nThe LRT-4 will work on for that lockring. So will the LRT-5.\nAnswered by Park Tool\nQuestion asked by\nJulia\nWill this tool work with Shimano XT M8100 cranks?\nThis tool will work to remove and install the lock ring found on M8100 cranks.\nAnswered by Park Tool\nQuestion asked by\nMaciek\nHi\nDoes this key fit shimano e6001 ebike?\nbestregards\nThe LRT-4 will not work on the STEPS E6001 motor. The correct tool is the BBT-49.3 which has a smaller diameter pattern than the LRT-4.\nAnswered by Park Tool\nQuestion asked by\nMichael\nI have a Shimano bb52 .73 mm...what tool do I need for this..thanks \nThe BBT-69.4 is the correct tool for that bottom bracket.
