you dont have to remove your engine to get clutch spring out although you do have to take off upper plate that fuel tank is hooked to and tranny (housing with two gear ) i think redcat calls it moderate gear set from that point you will have access to allen head bolt on what redcat calls a gear set remove gear set as pictured above and there is your clutch and spring GOOD LUCK i found this method alet easier then removing engine this way you dont need to worry about remeshing gears cause moderate gear set only fits on way
