+Loosen the nuts / bolts holding the engine sprocket and clutch basket on. \\
+The engine sprocket has right hand threads and the clutch basket has left hand threads. \\
+A reversible impact wrench has been used successfully to remove both the engine sprocket and the clutch basket nut. \\
+However, it's been debatable whether you can accurately install them back to proper torque without using a torque wrench instead. \\
+Whichever way you remove them, use regular six-sided sockets. \\
+They are less likely to slip and round off the edges of the nuts. Impact-type sockets are likely too thick to fit. \\

+Normally when loosening or tightening these nuts, you will need to **lock the hub & sprocket** - Do not wedge the chain. \\
+You can buy a primary locking tool (bar) or use a closed 4" BRASS hinge as a wedge. Place the wedge so as not to put pressure on the shifter shaft \\
+There are also several 4 and 5 speed [[techtalk:ref:tools116#engine_and_clutch_sprocket_locking_tools|primary locking tool examples]] in the tool section. \\
+A closed 4" BRASS hinge also works well to lock the sprockets and then you can use a pull bar and sockets / socket wrench. \\

+The threads should have previously been assembled with red Loctite. \\
+Using a propane torch (on the nut or bolt only) will heat up and melt / soften the Loctite somewhat to make removal easier. \\
+Remove both fasteners holding them on before attempting to remove either. \\
+Big socket wrenches or pullbars give you a lot more leverage to make removing the fasteners less strenuous. \\
+**Note**: \\
+The engine sprocket has right hand threads (lefty loosy-righty tighty) \\
+The clutch basket has left hand threads (lefty tighty-righty loosy) \\

+The engine sprocket and clutch hub should be removed as one unit. \\
+Both have to come out together to some point since the chain will tighten and neither will budge at that point. \\
+Once they are both moved out far enough, you may be able to get one or the other to come off without the other. \\
+Once the sprocket and clutch basket is removed, you can gain access to the mounting screws for the stator. \\
+You'd think both should slide off at this point. \\
+However, the magnets on the engine sprocket are very strong and will keep a good amount of pressure toward the engine until it's moved out so far. \\
+Pull the clutch basket out as far as possible and then maneuver your fingers both hands under the engine sprocket. \\
+Rock it side to side while pulling outward. \\
+Slowly you can rock it out enough to get your fingers under it to move it out far enough to release the force generated by the magnets. \\
+If the chain gets tight, move the clutch basket out some more and go back to the sprocket. \\
+DO NOT DROP THE ENGINE SPROCKET. The magnets can crack or break off and that's a different problem. \\

+However they come off is fine as long as they are not dropped. \\

+Make sure you already have a place to put them and a clear walking path before removing them from the engine. \\
+Cover them to keep dirt / debris off them until they are ready to go back on. \\

+Slip the primary cover back on and stuff rags in the openings when not working inside the engine to help keep out dirt / debris. \\
