A small tip ........when reassembling........you see those sharp edges on the spindles immediately behind the 7/16 BSF thread.......the shoulder of the start of the spindle.......I chamfer that sharp edge with a linishing belt or in the lathe if you have one. This makes assembly much easier and saves taking gouges out of the blades and so on when the spindles are passed back through. No need to go crazy with it, just a nice bevel will do. Also check the condition of the "Pad bolts" as these are often over tightened and the small cutaway gets distorted, this causes the spindle to jam up when you try to slide the spindle through. Again I just carefully linish off any of these high spots and good to go........Use a small smear of grease and cover these parts.....this will stop them rusting up if they are original ones and help with the assembly as well as down the track at some later date. Put a light smear of grease on the new stem tube too, or else it will rust, and on the new stem kits I have been giving all the new "Concentric" parts a light smear of grease just before final assembly, as this too will help stop things from seizing up if disassembly is needed at some point. Cheers............Greg.
