Default Dayton 1w533 Gen Set??

I HAVE A DAYTON GEN SET (LATE 1950's EARLY 1960's) IT HAS ONE 120V AND ONE 240V DUPLEX OUTLET AND A PUSH TO START BOTTON ON THE OUTPUT BOX. THE GENERATOR HAS THREE WIRES THE HEAVY ONE I WOULD ASSUME IS NEUTRAL AND THE TWO SMALLER WIRES ARE 120 ON EACH LEG. I AM NOT SURE IF THE 240V DUPLEX IS ORIGNIAL AS MY FATHER WHO BOUGHT THE SET WAS AN ELECTRIAN AND MAY HAVE REWIRED IT. THE BRIGGS ENGINE IS MODEL 23AFB TYPE 703585 SERIAL 61456 I KNOW THE ENGINE WAS REBUILT IN THE LATE 60's AS WATER GOT INTO THE EXHAUST. THE GEN WAS LAST USED EXTENSIVELY IN THE EARLY 70's AND RAN WELL. i REBUILT THE CARB A FEW YEARS AGO. THE ENGINE STARTS ON THE SECOND PULL. IT RUNS ROUGH AND THEN DIES. I WILL BLOW OUT THE FUEL LINE PUT A NEW PLUG IN. DOES ANYBODY HAVE ANY INFO ON THIS SET?? FROM OTHER POST I ASSUME THIS IS A PRIVATE LABLE MACHINE SOLD BY GRAINGER. GREAT FORUM

What you're describing sounds like a bastard set Kohler put out with a Briggs engine on it.
If at all possible, post a picture to make identification possible.

Grainger has amazingly good support for their stuff. Although this beast is pretty old, it'd be worth a call to them. They may have a manual, parts list, etc.

I believe Winco built generators for Grainger under the Dayton name also.

Bernie,
You mention that there are 3 wires coming from the gen - with one being a heavy one. I am currently working on a similar, smaller unit Model 1W531. I have one heavy wire and one lighter one. Mine is 115V only. The heavy wire on mine is for the 12V starter, and the lighter one is the hot lead of 115V. The frame is the neutral / ground. I would imagine yours is probably very similarly wired , but has a second 115V lead to give you 230V.

EUREKA I FOUND IT !!!!! i just found the original paper work. the order was for a dayton model 1W517 dec 10 1958 for $319.50 plus tax from grainger. what (watt) I have is a 1W533. so what is the difference?? it is 115/230 volt 3500 watt ac generator standard is one 115 v duplex and one 230 v duplex outlet.



I will see if I can post all of this info for others. i have the original dayton parts list, schematic, dayton operating manual, and briggs operating instructions for the 1W517. I will post after talking to computer tech guys as to best way for readablility.

I believe Steve is correct. The Dayton I have (same era) looks alot like several Winco's I have in many ways. I will post pictures and ask questions about them in the future. The 3rd. edition of the Intertec "Small AC Generator Service Manual" does not cover th 1W 533, but does cover 1W 761A and others.

here are the pics. to refresh, what was ordered in 1958 was a dayton 1w517. all paperwork shows 1w517 (schematic) the machine name plate is listed as 1w533. the rehestat is added by my father to regulate the charge rate. all is original except the rehestat (replacing the reisistor) and the paint. orignial color was a green that you can see in some views. any thughts out there. what is the difference if any between a 1w517 and a 1w533??? thanks bernie

Bernie. your model is not covered, however if you you find a wiring diagram, I would be interested in it. I am very much interested in the charging circuit. The abovementioned book (my previous post) does have some diagrams but I am not sure if they are similiar. ie., slow charge, fast charge posts. My Dayton is a 30WOO7, engine is a B&S 233431, it also has the " automatic idler" feature that appears to be common on some of these old gensets. Good Luck!

That generator looks very much like a Winco.
To find out the difference between 1w517 and 1w533 you could try grainger
at 1-800-323-0620. Those numbers look like grainger part numbers.

To get info on the engine contact briggs and stratton at
www.briggsandstratton.com

To get info on the generator end contact winco at
www.wincogen.com

Good Luck.

With the running problem you describe, it sounds like bad gas or traces of bad gas in the tank, and or fuel line, or old gas residue. you could replace the fuel line and remove the tank, spray in some gumout carb choke cleaner Stock number 7459. Spray some of the cleaner in the tank, put the lid on the tank and slosh the liquid around in the tank and then dump it out, if it is not clear liquid, repeat until the tank is clean. Also give the carb a shot of cleaner. Take out the high speed jet and give a spray in there also. Set the high speed jet to 1 1/2 turns open and the idle adjustment to 1 1/2 turns. If it starts and still runs rough you could open the high speed jet a little to see if that helps. Usually the way you set the fuel mixture is to preset the jets as described and once the engine is running and not stalling, at high speed turn in the high speed jet until the engine rpm starts to drop off, back the jet out to where the engine smooths out and then give it 1/4 turn more open, that way you have a little extra fuel when a heavy load is suddenly applied the engine will pull it and not stall. Do the same for the idle jet, you may have to manually override the govenored speed to get an idle speed, once you get the idle jet set then when you let the engine go back to govenored speed. If it sputters the fuel is close but not quite right. The engine should dig in and rev up like it is going to the races.

If the rough running is accompanyed by popping or missing, it could be an ignition issue. Something that old has points somewhere. If they are under the flywheel I prefer to change them rather than clean them because of the covers you have to remove along with the flywheel to get to the points. For me it is cheaper in the long run to spring for a new set of points.

It wouldn't hurt to check valve clearance also, since it starts the valves are probably OK,but if the gen is going to be used for emergency back up you don't want you gen quitting because the valves are too tight (when the engine heats up to operating temp).

Hey ! In looking at your pictures again, the points should be in the box that is below where the muffler attaches to the block.

Being the engine is a 23A Briggs and Stratton it will have the Magnematic type maneto. The coils on this mag will go bad just sitting. They also will run at low RPM but as you throttle up will start running poorly. Part number is 290880 for the coil. Price from B&S over $100.00. Check out the November 2005 issue of Gas Engine Magazine for a way to modify a later B&S coil, which can be found for nothing on over the hill push mower engine. If you use this modification the only cost you will have is your labor doing the modification.

got the article from a buddie. looks good talked to Grainger today. tech support went into the archives. looks like the 1w533, 1w517, and the 1w704 are all the same unit ??? there must be a difference.. 517 is the older and the 704 is newer. grainger said the gen head was made by " dynatech". I emailed them at dynagen.com and the reply was that it was not made by them. different company. the dayton generator name is definately made for and sold by grainger.

Since they are like Sears in the fact that Grainger just sells stuff they get from various manufacturers, wouldn't it be better to go directly to the source - in this case Dayton Mfg. of Chicago? Yes, maybe this particular model is unique to Grainger, but it was still made by Dayton.
Just my 2 cents worth.....

Another step closer to running. Rewired outlet box, new outlets, moved charge rate rehostat to allow heavy duty spec grade outlets, and made new feed through bushings for battery connections for electric start. She cranks effortlessly. Plenty of hot spark. Now cleaning out fuel system. Screen in fuel bowl was 3/4 clogged with rust. Fuel line is clean. hopefully she will start and run like a champ. After seeing the winco posts, this unit does look similar it. the beat goes on. thanks to all bernie

Smile Re: Dayton 1w533 Gen Set??

The Dayton 1w533 and the 1w517 are two different units. The 533 is a 2500 watt 120 volt only generator and the 517 is a 3500 watt 120/240 volt generator. Both of the have Winco generator ends on them but they were actually put together by Dayton MFG which is a division of WW Grainger. The DYNATECH that you came across was the parent company of WINCO. Now know as WINCO Inc. Hope you got the unit up and running.
