Re: '63 K NV4500 removal / reverse build thread

Putting the mainshaft back together was surprisingly simple. Toughest part was the syncro hubs and sliders with the spring loaded lugs that engage the sliders. It took a little patience and my 7 yr old son to get the slider ring over the hubs and lugs. Heres a shot of the 3-4 syncro hub being pressed on. Notice the absence of the reverse slider (between the bottom two gears) on the mainshaft. Yes that rear mainshaft bearing has to come off again! I bought that bearing 3 times due to stupid mistakes. First time, I heated it with a heat gun (turned two rollers blue). I dropped it on the MS before I noticed the overheated rollers. I used the press to put it back on. Second time, I found the reverse gear slider hiding under a shop rag after I had the MS almost fully assembled. Bearing came off again. The third one went on after careful scrutiny and without issue. Pressed on again. The parts guys were howling by the time I went to pick up the last bearing.
