Re: '63 K NV4500 removal / reverse build thread
You can see in some of the pics how the parts are "caked" with oil residue which looks to be baked on. The stuff had coated the syncros, making them real slippery and rough. I really think that the wrong oil was used previously.

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.

Re: '63 K NV4500 removal / reverse build thread
Chris, glad to hear that it finally went together (especially after 3 rear mainshaft bearings )
This will help when I embark on the nv4500 swap someday. Posted via Mobile Device

Re: '63 K NV4500 removal / reverse build thread
Thanks for posting this thread Chris. This will come in handy should I need to open up mine.

Re: '63 K NV4500 removal / reverse build thread
Thanks everyone for the compliments and input on the build. Shifting keeps getting better with every drive so I think that the new parts are starting to seat. This was a pretty easy rebuild and I'm no master mechanic by any means. Definitely gratifying to say that I did it myself and it actually works!
Thanks again! Chris

Re: '63 K NV4500 removal / reverse build thread
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.

Re: '63 K NV4500 removal / reverse build thread
Excellent read. This will be one of the primary references I use as I step through my first NV4500 rebuild. The pics are great so as I do my own rebuild I will document the progress and when finished, hopefully I can add a thread as helpful as this one has been. Oh, and that is a bad ass truck.

Re: '63 K NV4500 removal / reverse build thread
Thanks Richard. That build seemed so long ago.
Looking back, I wish I could have added much more info and way more pics but you get the point. The 4500 is something that you can do do in your garage with a little research and a few special tools. The book really helped a lot as well even though it was more geared (no pun intended) toward the Dodge units.

Re: '63 K NV4500 removal / reverse build thread
Hey Chris, were you able to use your main shaft and counter shaft? I think my m/s is useful (doesn't really look bad) and my c/s might also be usable but it shows wear at the end, where the fifth gear rides. Maybe it's ok, but I'm not sure about it.

Re: '63 K NV4500 removal / reverse build thread
Hey Richard, yes I reused both in mine. Are you talking about the countershaft where the larger gear of the 5th gear set rides? TBH, I don't really remember looking that hard at that part of the CS. I do remember checking endplay on the CS but that was about it. I think at the time, I was more worried about the 3rd gear cluster, syncros and the 5th gear nut which I later found out wasnt much of an issue with the 2wd transmissions.
You have a picture of the CS area that you're concerned about?

Re: '63 K NV4500 removal / reverse build thread
Recently picked up a 93 4wd minus engine. Gave the guy 300 for it just to pull the 4500. This will be my second 93 4500. After getting the trans out and salvaging the truck, I pulled the drain plug to see.....black gear oil....confirmed by the smell. Well, I planned on going through it anyway, now it will be required. Duh! Some people 😥

Re: '63 K NV4500 removal / reverse build thread
Here's a couple of images that show what I'm referring to. I want to believe it's normal wear and that I can use my c/s. But I really don't know. Trying to work within a budget but might have blown that idea by ordering a premium rebuild kit from quad 4x4. Still, the logic is that if I can barely afford to do it once, then I can't afford to do it twice. So if I have to get a new c/s I will but not really lookin' forward to it.

TBH, I have no recollection what mine looked like. With the absence of a bearing there, Im going to make the assumption (and it is an assumption) that the area you're concerned about either has very little movement (the gear spins at the same speed or close to the same speed) or very little pressure that it's subject to. Id still get measurements to be sure. It would probably be cheaper than buying a new CS

Re: '63 K NV4500 removal / reverse build thread
One question I have--and it may have been answered but I missed it--will this trans bolt to our stock bellhousings?
Specifically, will it bolt to the truck bell with the side mount ears for '60-'62 trucks? -Brad

Re: '63 K NV4500 removal / reverse build thread
No, you will need a 4500 housing or aftermarket housing with the correct side front output.

I did mess around with a few scattershields and the idea of running the factory BH that came with the 4500 but in the end, a couple of side jobs and my laziness won out and I bought the AA unit.
