69 Napco axle.

I have a question for you guys who know Napco.
I have a ford N600 Napco conversion. I believe from some literature i purchased that my front axle is the 7500lb version. I understand Napco used a lot of Eaton differentials on there axles. I'm just curious what mine would be. I wouldn't think the H072.

HO110 is the next size up. Those are typically in 10-lug rear/5-lug front mediums. Not sure what the next size up was from there.

Re: NAPCO Thread

I think the next up from the 110 is 13500, 15000 and then 17000. The trucks with 5 10 wheels and 6 hole Budd wheels must be HO 110 or 13500 axles and the locking hubs do not have the grease zerk in the center. the trucks like the two of mine that have 10 hole Budds have the zerk in the center and I think are HO 15 but that's not written in stone yet, still looking for more data.

Re: NAPCO Thread

That's a cool truck. I see you have another N-series. Don't see those too often...and I go to a few big antique truck shows a year. Same goes for the GM B-model.

Yeah they aren't very common, but I have seen more of them in North Dakota and Montana than anyplace else. The Napco truck is pretty rusty in the cab. I plan to swap the running gear to my grain truck. Everything should swap over. I'll just have a new rear driveline made since the grain truck has a longer wheel base. I'm not sure why but all of my trucks are 4 wheel drive except the grain truck.

Re: NAPCO Thread

Not sure when they stopped, but I had a '71 C/30 NAPCO at one time. The need for one tons remained till late-70s and they went on with the medium-heavies years beyond.

Re: NAPCO Thread

Now that you mention it, where is the proper thread for C30 and K30 stuff, would feel better if it was under heavy stuff but you tell me?

Re: NAPCO Thread

Great bump for one of my favorite threads. 58 GMC only $4400

https://maine.craigslist.org/cto/d/1...622380824.html

Very rare original Napco factory 4x4 truck. Spent most of it's life in an old Colorado mining town. Surface rust only. Very solid body and frame. All bolts turn if you need to work on something. Nice running 283 V8. Electronic ignition. 5 speed trans. Clutch good. Exhaust good. Brakes work but hydroboost should be rebuilt for more stopping power. 4wd works fine. Operational dump bed and power tailgate. Lights work. Military tires have some dry rot but holding air fine. Everyone that sees this makes some type of comment about how they would hate to see this behemoth bearing down on them in their rear view mirror. Very one of a kind striking truck. Dual wheel chains on the sides were for Rocky Mountain winter running. Sold with Maine bill of sale as well as have the Colorado title for it. Call 207-239-87 zero four. If ad is up, Truck is still available. Emails that look fake will not be replied to.

Try these guys. Lot of the parts are the same. While they aren't NAPCO specific they should be able to help.

https://www.vintagepowerwagons.com

You'll want the NAPCO shop manual pamphlet when adjustments are made to toe-in. If it's like my 57, each rod end has different thread count (course/fine).

To get correct toe, you have to turn one rod end 1 turn and the opposite end 2 turns etc. The pamphlet has a chart that will tell you which one to adjust and how much based on your initial measurements.

Re: NAPCO Thread

Thought I would share this 1958 GMC Napco I helped a buddy get yesterday. Its a V8 with a three on the tree w/overdrive??? We looked it over for about 2 hours. It has zero rust or repairs anywhere to the sheet metal on it. I'm a bit suspicious of the bed though. It has a fleetside emblem on it and I don't think that would have come on a GMC. Can anyone confirm that this emblem shouldn't be there? Neither one of us know much about these trucks but are learning.
