Stovebolt.com Forums The Parking Lot Big Bolts The Stovebolt Volunteer Fire Department Barton American UA-50 Front Mount Pump

I am building a photo album/gallery with related photos and information about the Barton American UA-50 front mount pump. As I posted earlier I was able to purchase a spare Barton American UA-50 pump which was mounted on a 1957 Dodge. The previous owner had purchased the 57 Dodge for the cab and did not want the pump. I was also able to purchase all of the related American Fire Apparatus engine and cooling system components which had been a part of the total instalation of the UA-50 on the 57 Dodge. My plans are to disassemble and rebuild the pump and each of the components and create photo documentation along the way.

Thus far I have uploaded photos of the pump and components as mounted on the 57 Dodge fire truck:

Bob,

This is great stuff!!! My U-40 from my '41 Chevy is currently disassembled and in primer. Just ordered 5 new bearings for it (4 different bearings, two of one), as well as a rebuilt tachometer gear.

Though I assume my truck had the aux. cooler when built, it has been lost on the way. If you know of one available, please advise. Otherwise, I may ask for your help in fabricating one (I don't think they're all that complicated).

My truck (apparently) had no pump governor either, though it originally had the chevy top-speed governor.

Learned a lot about the pump when we tore it appart. Took many photos, but mostly with my iphone, which does not take great pix. Am assembling a rebuild diary like you. Not too far along, but let me know if I can help.

I've got a lead on a batch of Barton pumps (already have two spares) from a fellow, just need to "seal the deal".

We're gonna rebuild the primer, as well. They're my absolute favorite! An oil-less primer, orginally developed in the '20s. American was "Green" before Green was cool!!! It's such an elegant solution.

Keep us posted!!! Your truck is awesome.

Thanks Michael,

The internet is really an amazing source of information. In most cases somebody has seen it or done it related to almost any subject you can imagine.

I am always searching the net for information about projects I am working on and as a result realize that in return it is important to post information that may then be of use to someone else.

The hardest part of providing information is to find a spot on the net which allows the information to have a long life.

The weather was finally a little warmer recently so I finally go into the barn to finish taking some additional pictures of the UA-50 pump and components before I start the tear down.

I added photos for the vacuum primer, pump frame mount, and the pump itself:

Bob -- Welcome to Stovebolt.com! We've been here since 1995 and have no intentions of going anywhere anytime soon We'd be happy to host your photo diary here as an on-going feature or tech article.

My truck has a similar front mounted pump...

A Barton American U-50 pump....

Is it the same?

I don't have a governor or heat exchanger...

I do have the vacuum primer though...

Hi 1958GMCnut

My truck has a Barton UA-50 which is very similar to your U-50. The pumps models designated with UA (instead of U) denote a pump with the heating/cooling jacket cast around the pump. This heating/cooling jacket is plumbed into the engine cooling system to help keep the pump from freezing during cold weather.

Bob

Great info!

Thanks

I hope to add more photos and info now that nicer weather has returned. My goal is still to tear down and rebuild the spare UA-50 pump I have and to photo document that process. Probably take me more than a few months as many projects again compete for the nicer weather.

Also it took me a while but I found the portable American Pump that belongs in the rear bin of my fire truck. I will take some photos and post them when I get a chance over the next few weeks.
