Anyone know about Hol-Gar generators?

I have just acquired and old military? portable generator made by Hol-Gar, Zeus Electric Power supply. It is a 1.25KV 120 volt unit, model number Z-1250, which sits underneath a 3.5 horsepower Tecumseh vertical shaft engine. It has a carry handle over the top of the engine. I have had the unit apart and cleaned, replaced a broken govenor gear and am about ready to give it a test run. I cannot find any information about this unit anywhere. Came with engine painted army green. Any ideas or info would be greatly appreciated. I have never before even seen a unit where the engine sat on top of the alternator. Thanks, DaveBos

We have one where I work that is just about like that. It is branded "antenna specialists", but was obviously not made by them. It also has the Zeus name on it IIRC.

Re: Anyone know about hol-gar generators?

I am trying to find out a couple of things about it. The outlet on this one has been changed and the winding are directly wired to a duplex recepticle. There is nothing else between the windings and the outlet. When I had it apart I could see that each output lead is connected to three wires, as in three sets of windings. Should there be anything else there that is missing, such as a circuit breaker or etc? I can get a couple of pictures and post if need be. Thanks. Dave

Our unit is a good distance away, and it has been at least a year since I saw it. I don't recall seeing any type of overcurrent device, other than the engine's limited power capability. Given the performance of ours, I think the engine would die before it produced enough fault current to hurt the generator end.

Thank you Wayne for the info. It pretty much tells me what I needed to know. I will not worry about a breaker and just buckle the unit up. Will be giving it a trial run in a day or so. I got this little unit for nothing and only have a small amount in it with the carb parts, a govenor gear and a few gaskets and seals. Will report how it goes after I get it running. Dave

Well folks, I got the little fellow back together today, and it starts on the second pull, runs very nice and with the governor set as it is puts out 117.6 volts. I ran my grinder on it and it works perfectly. I must say I am totally pleased with this unit for what it is. I will have to get an air cleaner for it now that I know it runs. Also, probably a valve cover reed valve assy as it did drip a drop or two of oil from it, bit first I will give it a bit of run time. Great little power supply unit. Dave

I had to make linkage for the carb for now, but will be looking for the proper linkage. Dave

I do not think this unit is military because it DOES NOT have the Sheilded Ignition system. Secondly I do not think itis that old, a relative term, because when did Tecumseh appear, late 50's or early 60's.

Both statements are quiet possibly right and I cannot dispute them. I based my thoughts on the following. First, any info I could find on the Hol-Gars said most were built for military contracts. Secondly, the engine was definitely army green. As for the age I considered a tecumseh engine of probably early sixties vintage to fall in the old catagory. Certainly not antique, but old. By no means am I trying to say I am right and I posted this with hopes of being able to find out any info I could on the unit. Any guess as to the actual age? Thanks to all for any leads as to this little fellows origins. Dave

I would say that our unit is from the late 60's- early 70's. It is very similar to your own except for a metal tubing basket to provide stability and easy handling. I have an old catalog around here someplace that lists these units, but cannot put hands on it at the moment.

Hol-Gar is earlier than that, although that unit surely looks later.

I have a Hol-Gar generator that was made for the Navy, to power a microwave link. It also does NOT have shielded ignition, but is so plastered with MIL nameplates and olive-green paint that there is no doubt of its origin, nor that all the original pieces are present.

I am not sure what Hol-Gar had to do with it, actually. It is a B&S motor, but has Raytheon data plates and Hol-Gar is mentioned as well.

I think maybe Hol-Gar made the generator unit, and either Raytheon or Hol-Gar integrated the engine and generator into its portable case. Raytheon was the contractor for the microwave part, no doubt, accounting for their name.

That one doesn't look MIL, but the nameplates will tell the story, unless some pieces have been replaced since. Presumably Hol-Gar made the generator head.

Mine produces 400Hz power, so it isn't good for much aside from lighting or maybe battery charging. Does that one make 60 Hz power?

Forgot to mention, mine is from 1958.

Here is everything I know about this unit. First the plate info:
Zeus Manufacturing
Hol-Gar Division
Model Z-1250?
Serial BP2 54
1.25 kw
Ph1
Freq 60
Volt 115
Amp 12
3600 rpm
Pat # 3012161
I looked up the patent # and it is for an alternator, applied for in 1957, Dated Dec 5, 1961

I am sure that the gas tank, possibly the carb and definitely the outlet box have all been changed. The linkage for the carb is makeshift, temporarily done by me, simply to test unit. It originally had rubber feet about 2 inch diameter it sat on, but they had been burn't off from a fire at the house it came from. The paint on the entire engine, except the carburetor and air cleaner was Olive drab green. Intake manifold was also green. I have no other identifying features, as the tag on the fan guard was burned off as well.
I rescued it from a jumk pile, where it was soon to become scrap. I looked up the patent number this morning, and that dates it at no older than 1957, probably after 1961 since it says patent no on the tag and not patent number applied for. I know this doesn't help much, but it is all I have to go on. Dave

Thank you for the page ad. That is very much like what I have, only briggs powered. I much appreciate your posting this. Dave
