I am currently rebuilding my NV4500 for my 93 GMC stake body truck. This is a great thread you put together. I too wasted 2 new rear mainshaft bearings while making mistakes putting it together. Lesson Learned. With my trans I could find NO way to take the mainshaft out once it is setting in the trans with the bearing on. Twice I destroyed that bearing so I could get the shaft out of the trans. First time was a slider incorrectly installed and the second time the reverse slider slid forward and jammed into the gear. I has just enough room to slide off the teeth of the gear and jam. Right now I still need the snap ring for fifth gear so I can finish putting it together. Thanks.
