NV4500 swap is underway

[argonaut]

Larry,
How has the modified, aluminum adapter housing from the NV4500 to NP205 been holding up? I'm getting ready to do my swap in the next month or so and was hoping to get your feedback. Let me know what your observations have been. Thanks!

Still not sure why people are nervous about the aluminum adapter but yeah, it’s working fine. In May we ran a couple thousand miles around Arizona and Utah. 200 miles in Canyonlands bouncing and crawling for 2 days in 4 low. The front shaft tried to commit suicide and pulled the front yoke on the 205 loose and still didn’t cause any issues with the aluminum bracket. The twin stick 205 is still giving me fits though. That beoatch does not want to SHIFT wants it hot on the trail

[argonaut]

Good to hear. It never hurts to check!

i have the AA spacer and case hanging off the OEM AL housing in my M715. for the last 5+ years. no issues what so ever. has at least 20K on that rig since built. pulled the trans and tcase for a clutch issue and re-checked everything while it was on the ground and the studs/nuts are tight and right still.

I rock crawl my nv4500 with a doubler on the end.

Hey larry nice set up im starting on my nv4500 swap im still trying to gather up all parts I got trans aa adapter 10 spline 205 31 spline output What do you recomend should I run it like that or upgrade to 27 spline also I got 93-95 oem bell im mounting behind my 5.3 is that going to be an issue the only thing I need is the pedal assembly you where I can find one.

There's a guy on the Pirate site that has a stock of new OEM late model NP205 cases. Bought mine for $80. AA has an adapter (basically a 2" solid spacer) that sells for around $60-$70 (I think?). This is the way I went to get the strongest and shortest (and newest) NV4500/NP205 setup. I also got a brand new 32 spline and bearings from him. He owned a company that converted/upgraded new trucks to HD specs for the forest service and emergency vehicle applications (ambulances, etc.)

[Alberto]

Thanks for that info but my nv4500 has that big 31 spline output shaft that can only be used with a coupler think

31 spline is Ford and I don't think the 4500 used 31 splines... GM: 27/32 and Dodge 23/29 splines...
GM switched the bolt pattern early on to the Dodge style so if you have a Dodge trans or an early GM BH, they may not match.
Advance Adapters has a conversion guide you can download or ask them to send it to you w/ lots of info.

It's possible to use the early TH400 32 spline input for the 205 and not use the 2" spacer to get 2" shorter, if shortest is the goal. I've actually got the long input and spacer like sunsoaked but debating whether to convert...

I searched and just looked on pirates classifieds. but didn't find any clues about the person w/ the round pattern cases. Got any more info?

Thanks!

Casting number on the nv4500 C-16812 thats gm casting numbers

[franken]

Well, Larry pointed out a possible 31 spline setup I never heard of...

Those numbers mean nothing to me but it sure sounds like what I said before…an AA NV4500 to 10 spline 205 kit. You can post up pictures (in your own new thread that you will start) and we can try to help you.

As suggested, you need to figure out what you have, then figure out what you need to put things together. Nobody can figure out what you have if you can't, but it's pretty easy to see you don't have what you say.
It would be best to start your own thread since this is likely to take a while.

Well, theoretically he does have a 31 spline NV4500 if it has been cut to work with the AA kit

[franken]

Sorry, my ignorance is in full view.
And worse, I got lippy. Sorry!

[Alberto]

Thanks for getting back to me larry so why did you replace the 27 spline for round patern 205 did it not work out for you after you replace the input

No problemo... See post 284 why I went to a round 32 spline 205 (to lazy to repeat the same story already posted here)

[Alberto]

So what failed was it the coupler between the 2 shafts

DL,

I was cruising different sites this weekend and somehow came across this model. I'm not into RC's, but couldn't help to think of your rig when I saw it.

Heck, it maybe yours for all I know. Nonetheless, here you go.

That is really cool! Nope, its not mine. I don't have near that kind of talent to build something like that.

[McMurray76]

Too cool.

Hey Larry
was poking around on ebay and saw this:

That's your truck isn't it? Seems they "borrowed" your pictures...

Yeah, that is okay. Someone from Xenon sent a message through Flickr quite a while ago asking permission to use my photos. Although, nobody from JW Custom Accessories asked permission they must have gotten them from Xenon. Thanks for the heads up though!

Hey larry I know its been a while since the last time but im getting closer to installing my nv4500 and 205 ifinally got clutch pedal assembly got mc installed just got a new flywheel for a 2007 6.0 i dont think i mentioned my 79 k5 has a 08 5.3 so question is what clutch and plate do I need to complete the swap. Alot of people run a old school chevy clutch but im not to sure I been reading alot im kind of confused. According to the forums the 6.0 flywheel makes up the gap on the crank on these ls engines but I run a clutch for a 6.0 I might have disengage issues not sure what do you think?

I don’t have the answer to that one buddy. I’m running an 8.1L which is a different animal to the Gen III small blocks where the 8.1L accepts the same ole 12” clutch and pressure plate as any other older SBC or BBC. You’ll have to ask around to someone that has done a NV4500 behind a Gen III small block
