Nice find!

Remains of an NV4500 input gear...which was why i was searching for exploded views.

Been sitting a while, fortunately it's getting replaced so I don't care much about the surface rust.

Corresponding gear on the countershaft...

Counter shaft.

Just trying to inventory all the parts i need to replace right now...hopefully it's still worth doing.

Good lord, what was that tranny behind?

Gotta be a Cummins.

PM me the final list when you find what you need to replace, I'll see what I can do for you rene, we have some pretty good hookups for parts.

IIRC it was behind a healthy 427 BBC. It was run critically low on lube, then the input bearing had a meltdown. The resulting heat transferred to the first set of gears softening them, then the input shaft sheared. The guy i got it from said it didn't get noisy or give him any hints that anything was wrong until he had no forward gears...

It was given to me as a basket case, so I'm finally trying to find out whether or not it's going to be cost effective to rebuild.

You gotta go through with this project. I would love to see how a nv4500 does with a 6.2 in a K5.

 

[tRustyK5]

Well, it'd get my rpm's down to 1840 rpm at 65 mph (currently spins 2520 rpm @65). Should be much quieter inside, and should net me another 3-5 mpg. It'd also get me up to 32 spline stuff which is another bonus IMO.

Not that it's a high mileage commuter, but it would be cool to break into the 20's for mileage while running 40's. Other than that it should be nearly the same as the SM465 I have right now. 2nd, 3rd and 4th are pretty much identical.

Nice. Saw that about 10x a week when I was working at the transmission place, but they were a bit bigger...

How 'bout airfare?!
I'd love to if I actually had worked on a 4500... All I did were Roadrangers and 10-speed Rockwells.

The guy at the bench next to mine (before we did the "cell" thing) did all the 4500's that came in, maybe 4-5 of 'em in the 6 months I was there. I seem to recall him having a hard time getting the mainshaft back into place properly ("properly" meaning "not falling to pieces"...) a couple times, but that's all I remember.
