Default 5hp Atlas Imperial Engine

I have been watching this engine on Craigslist for almost two months now (didn't have the cash to pick it up when I first saw it). The price kept coming down and I was finally able to pick it up. Its an Atlas Imperial engine model 1LA3. Its a 5HP. Looks to be complete with all gauges and filters. The oil pressure gauge has printed on it " Atlas Imperial Diesel" which I thought was Pretty neat. Hasn't been run in at least ten years. It originally came out of a small logging town in the coast Mtn range here in Oregon. Hope to have it up and running soon. I have wanted an Atlas Imperial diesel for a long time but don't have the room for one of the big diesels so I was really excited to find this much smaller diesel with the Atlas Imperial brass tag on it. I have searched in this forum and found some info on this engine, is there any way to date this engine?
Thanks
Ryan

Another question that I have come up with is what is the canister next to the oil filter? The fuel does run through it so it must be a filter or water seperator? Can it be cleaned and reused or do I need to try to find a replacement? I tried searching the Bosch number that was on top of it but couldn't find anything.

i would give a guess that it would be a fuel filter normaly i see simular setups on other old diesel engines to have a fuel and oil filters. Looks like there gonna be some massive electrical work and cleaning.

The filter looks to be an American Bosch # FSA-10A-3, going by the number on the top of my new old stock one out of the box. I also have a new old one in an opened box but I let the sun get to the number on the box so it disappeared. There seem to be a few others with different suffix numbers or lack thereof, so maybe there are different media sizes available like with many filter styles.

Does your's look like these? I was going to use mine on an injector tester for my shop but I certainly could also sell them for a good price if anybody needs them as I have different filters I can use for the tester.

The inlet is on the "top" and has a bleeder. The outlet is on bottom and has a drain screw.

Hope this is useful.

Ryan, I have your engine pictured in my 1945 diesel engine catalog and they are talking about it being an new development so that dates it as early as just after ww2 and they are calling it an Atlas-Lanova.Lanova would be the designers of the patented combustion system which they licensed to several manufacturers.They show 2 sizes 5 HP and a 3 cyl 15 HP both operating the generator @ 1800 RPM. Bore 3 1/8" stroke 3 3/4" compression ratio 15:1.the 1 cyl was 3 KW and the 3 cyl was 6KW or 9KW @ 80% Power factor.they picture it on hoists, pumps and a combination generator and air compressor.They offered electtric start.your starting equipment looks like Delco typical of late 40's or 50's--actually more like 50's---see the necked down body on the gen.
My next newer diesel engine catalog 1954 doesn't show this line of engines and is showing atlas as manufactured by the national supply co angine division and calling them Superior-Atlas.Progress was killing another good old line of engines.
My guess would put your engine in the early 50's for manufacture.

Thanks guys for all the great info. Ehpower2, yes its going to need a good cleaning. All the wires seem to be going to the right places but could be redone a little nicer. KidDynamo, I used the part number you listed and went to my local parts store and got a filter. It matched up perfect. I could have probably saved a couple bucks buying one of yours but I have a bad habbit of getting in a hurry. Enginenut2, thanks for all the info. I hoped it was a little older than that (like maybe 1939;-) but I still really like the engine and won't be getting rid of it any time soon. Can hardly wait to hear it run. All the internals show very little wear and the bearings are nice and tight. I relapped the valves and gave the cylinder a really light honing and carefully cleaned the injector and pump. Should have it running in the next couple days. Still debating repainting it but it has a lot of original paint so I will probably leave it for now. Enginenut2, do you have any scans of the articles you have on this engine?
Ryan

Ryan, Be glad to share scans/copies.From my past performance on scans, I think I can get you better reproductions with copies from the local shop which I will do if I can get a mailing address and an idea of how many pages of the entire Atlas-Superior article you would need.The info on the little engine would be only about 5 pages.
regards
Bob

As an add on to the info Enginenut offered from the Diesel Engine Catalogue, my 1942 shows it as an Atlas Lanova and in 1947 it is called the Atlas Junior. No mention in 1939, I only have the 3 catalogues.
I posted pictures a while ago of the two I restored, they were pretty rough.
Ryan, I sure wish I could've come across the one you found, that's the condition I like to see.
As for the fuel filter, both of mine had the same Bosch filter, one I judged "clean" as it still had the fuel lines in tact, I took a chance and reused it and it is fine. The other was rusted thru and I replaced it with another setup, didn't think there was any chance of finding a replacement, shoulda asked
Ryan, I just went back and looked at your pics again, mine don't have the rope starter attachment, the battery charging gen is mounted on the same side as the starter (on the two bolts just above the starter) and Alas Imperial is embossed in the radiator tank. My pair only came with one radiator. I later found that the radiator for a 4 hp Witte upright diesel is a very close match, and I ended up using it because the one radiator I had was not usable.

Gus, thanks for the added info. I saw your posting a while back and thought that your engines were really neat. It really surprised when I saw this one on craigslist and that even when it was down to only $200 it still just sat there. I had to go for it even if it was a little bit of a drive. I noticed today that the charging generator is not original. The mounting brackets look home made. There is a bracket right above the starter. My radiator does not have any embossing. I also don't see any mention of lanova or junior on the brass tag, just "Atlas Imperial Diesel, model 1LA3, serial number 102-017, 1800rpm, 5hp. It looks like the top tank on the radiator is brass. I don't know if this would make mine newer or older than yours, but my guess would be that its newer than yours. Is your serial number way different than mine? I tried to charge up the fuel system today but it looks like my injector pump is going to need a little work. When I was bleeding the system and got to the injector end of the high pressure line fuel kept running out of the tube even with the engine stopped. I also could not get the injector to pop off. My guess is something in the pump is not closing like it should. Hopefully I will be able to get it working.

Ryan, the SNs on mine are 102-201 mod 1LN29 and 113-215 mod 1MD2, One was AC the other DC. Still haven't done anything with the generators, I'll save that for winter. The engines are identical. The price you got is VG in my book, the Atlases seem to be more prevalant on the west coast. Not even gonna say what I paid for mine, let alone what it cost to get them up and running. I will say that I bought a total of 6 engines from one guy and the average price is OK.
As to the fuel problem, the port on the injector pump piston should close before tdc on the flywheel. Look at the flywheel, you should see a mark with PC about 4 or 5 inches before TDC mark. Possibly someone was adusting yours and has it timed too late, I hope it's not broken. Also there is a spring loaded delivery valve inside the top fitting, fuel should not "flow" with the delivery valve in place. That may need clarification. Under normal injection, a small amount of fuel will push past the delivery valve, but when timing the engine the delivery valve is removed and timing is accomplished by adjusting the plunger under the pump, until you reach a point where the fuel will stop flowing at the PC mark, PC meaning Port Closed. Also I believe that these engines may have also been supplied with DEMCO injection equipment, my later SN has two marks, one marked PC and the other unmarked, but about an inch later on the flywheel,, This mark would probably be for the Demco pump. One of my diesels, I think the 4 hp Witte has is arrangement and is explained in the instruction manual. I'm kind of assuming your's has American Bosch equipment as both of mine do.
If you want to get inside the pump or injector, give me a shout, I can copy the pages from the AB book that cover your pump and injector, or give me a call, I'll send you a message with my phone #. The equipment is pretty simple inside, but you it helps if you have a map the first time thru.

Got the little Atlas up and running today. Seemed to run pretty good. Generator was putting out some power but will need a little more work. It sure is nice to have the electric starter. I was surprised how quiet the engine ran. Almost no noticable diesel knock.
