That's the part that brings my confusion. Reversing the spider gear. When I looked up the parts list, and the exploded view, there is no "spider gear". I see the bevel gear and was thinking that was what people are talking about, but I'm not sure. I don't want to do something without knowing that it is what I am intending to do. Cause damage and have to buy parts anyway. Are these two terms equivalent? Spider gear and bevel gear?
