I need to remove the stator on a Blue Star 185 to clean out a dirt dobber nest. What comes next after taking the 4 long bolts out from the endplate? It looks like I need to remove the center bolt that goes into the rotor shaft so that the bearing can come off with the endplate, but not certain if that bolt is left-hand or right-hand threaded and the best way to get it out...Thanks for your help. Also, is there a service manual available that would have these procedures documented?
