Leaking 727

lYou mean the bolt in the back?Loosen the nut, hold the bolt, then turn the bolt 2 to 3 revs out. Count exactly!
Use brake cleaner and the orange tread sealer like the one in the picture from Mercedes. Im pretty sure its from loctite or 3M. Dont use silicon, the sealer above works with oily treads, silicon not. Screw it back in and tighten locknut. Yoz can adjust the front band if necessary, follow the manual.
