What's new

Found a nv4500 assist in identifying it porfavore

Ok tough guy, ya know alot of those things have an eccentric shaft lock, maybe you should wear a jason hockey mask when you goof with such things ehhh!
 
I know how they work. It was released. But raw shaft materials (no coating/mill scale/hard face) rust and swell and they love to do that in wet lumber/open air winter environments.

Bitch was stuck. Other side came off easy.

Everything is all apart with the exception of this bearing on the counter shaft.

Guess just cut the cage off and then jaws of puller could get to it.

Ok so I have this 1995 NV 4500 case and I have a later NV-4500 that this website leads me to believe that I can get a good counter shaft and then use the main shaft, input and gears from it and have a complete working NV-4500 transmission.

Using gear info from tech note 4 at the site below.

According to everything I've read the 1995 is the first year to use the 5:61 first gear ratio and this ratio is used clean thru to the last year of the NV-4500.


I will check the main shaft gears tooth count to prepare and make sure they are the same as the later NV-4500 I have.



Pic below of the later (GBDW) <- ident code NV-4500 and its main shaft.


Gear teeth from left to right
---22, 29, 37, 39, 35:

I think I might have to replace the gear on far right with one for the proper 1995 counter shaft gear.

So I'mdoing this right by installing a new 1995 cluster / counter shaft into the 1995 case and running the 2000+ nv4500 mainshaft while changing out the one reverse gear to correct for the countershaft yeah ?

The old cluster mating gear of the input was ground down as much as the input so using no gears except maybe the reverse idler from the 1995 transmission.

Anyone have a early idler gear and shaft in excellent shape they wouldnt mind selling ?

Well I just bought a 1995 counter shaft cluster and it looks like the reverse idler is in good shape so this should be together asap unless I missed a step.
 
Received the new counter shaft cluster gear, working on the case next and found bovine magnets and or some hard drive magnets I could glue to the inside of the case.

The reverse idler looks to be in good shape as well as the shaft it spins on so will most likely be reusing those parts.

Pics later.
 
Saw this website and while I think they are wrong everyone has an opinion.


The opinion I'm speaking. of is the features that identifies the year of the transmission, in this case the reverse idler. .

My subject has the wide reverse idler, they say that would mean its a 92-94.

So whats the ppinion

Interchange for NV4500's.

Using a 1995 countershaft / cluster gear I'm of the opinion I can use the main shaft from the 96/97+ that I've owned for 5+ years now and somewhat mix and match the main shaft and gears to get the outcome Im wanting.


First a bit of info of what the shafts have depending on year of mfg, then my parts and a crude diagram as to what teeth the gears have.

Bought a set of these but since quad4x4 does not list timken part numbers on their website I bought what the local napa had on the shelf.

NV-4500 Timken set 45 LM501310 LM501349

And quad4x4 lists 4 numbers for cup and cone front and rear on their website.

QU10142
QU10143
QU10144
QU10145

So it looks like I bought two sets of one and none of the other.
 
UPDATE: bought the correct bearings races from what was quad4x4 for the counter shaft and the reverse idler.

Got the custom bearing retainer mostly made.

WELL I cant use the early 1991-1995 factory GM bellhousing as it has the 4:30 -5pm clutch fork.

20221223_113734.jpg
 
You are speaking of the gm 15990014 ?

It most likely wont hold my isuzu clutch fork.

Where is the slave cylinder on the 5pm fork position?


You can. You just dont want to.
 
Got a text from machinist that my newly finished 1.250 / 10 input shaft on a early nv4500 is done if anyone else wants one of these done pm me I'll hook you up.

But wait theres more...

Doing both the SM465 and the NV4500 SIMULTANEOUSLY.

Have the 5 inch (Most here dont understand the reason ( shown in their posts ) why I use the 5 inch stickout and not the 4 inch stickout that AA already makes, im intelligent enough to know that 2 inch spline connection is better than one inch, see the pics in this or another thread, hence why I didnt use the short 4 inch stickout custom AA / ORD sm465 main shaft.


Found and am in contact with the manufacturer to conform the correct vintage nv4500 their bellhousing will work with, ready to pull the trigger on that item.


Damn pae your threads are like a bad acid trip lol. It just keeps spinning and spinning, fk I want to get off but I can't!:flipoff2:
 
Not about cashing in its about have a more universal drivetrain.

The ability to pull a np205 off a sm465 and drop onto a Turbo400.
 
Cash in/wrap up/complete/finish....the venture/project/black hole.

You found a reason to do this and looks like you are about to, cash in.

Maybe cash out is better term. But it looks like it's about done. Cheers
