similar to VICTA 4 STROKE lawnmowers... lol
actually... there wouldn't be any carbon tax on one of those generators if You got one now... lol
240v AC 50 Hertz or cycles per second..
GREAT....

I'm not ex-army - I just bought the generator off my boss who picked it up at a disposal auction, and it came with plenty of paperwork including the manual. I've been meaning to get it running, but I still need to get a round tuit.

most industrial engines I've seen were all single port.
Just noticed the 4thou/0.10mm clearance and the 0.4mm plug gap.
4 thou was ok for twin ports but singles should really be abit looser than that about 6 thou/0.15mm,
Also pretty small plug gap, I know they under less load than a car but still I've always run 0.6mm on a stock application.

does it have a generator??
or is it just a shaft with fan on the end...??

The logbook has the same numbers as the manual above, so single port 1600(Crank start only)

They were 1600 single port, with a magneto. As long as the oil was changed regularly and were not operated in confined spaces, they gave great service.
I got one from a surplus auction many moons ago. Put a distributor in, changed manifold and carby (I had a home made manifold with a side draught weber set-up) and put it in a '69 lowlight Kombi I had. The kombi was sold about 2 years later with the motor still going strong.

Does anyone know what oil can be used in the governor. It states that SAE 10 oil is required, so is there a product thats readily available that suits that requirement.?
Anyone have a part number etc for the replaceable air cleaner paper element?
What went in the box in the compartment below the control panel?
Has anyone got a full electrical schematic, operating specs etc for the gen-set?
Anyone got any parts or literature not needed and they want to go to a good home, I just bought one in top condition and want to keep it that way.
thanks.

http://en.wikipedia.org/wiki/Motor_oil
"The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics. SAE viscosity gradings include the following, from low to high viscosity: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. The numbers 0, 5, 10, 15 and 25 are suffixed with the letter W, designating their "winter" (not "weight") or cold-start viscosity, at lower temperature. The number 20 comes with or without a W, depending on whether it is being used to denote a cold or hot viscosity grade. The document SAE J300 defines the viscometrics related to these grades."
I thought i saw it in my tribology notes, but that was converting ISO# oils to SAE weights based on predicted operating temperatures. Google pulled through though. So from that paragraph, a 10W oil (single grade) should suffice.

to reduce an overvoltage problem on an alternator? dont think so. The governor needs to maintain nominal output volts at 50Hz. Only reduce the speed if its an over-frequency problem.subimanx wrote:Slow the engine RPM. ..
But yes, it would be great to get a copy of the manual in to the public domain. And lets not turn this into a debate about copyright ......

So does anyone know of a product readily available thats SAE10 / 10W? I suspect that pneumatic tool lubricant might fit the bill but I cant confirm the oil weight.

depends on what level its been classified as. i know the equipment i use to work on was all secret and above and that was radios, comms gear and weapon systems.
hopefully someone doesnt get in trouble for posting it if it happens.

We are trying to determin if it is actually an overvoltage problem and there is definetly nothing wrong with checking the speed at load is actually what its supposed to be,its the first thing in the diagnostic you would check. And I'm sure you actually meant to type "overvoltage from the altenator" Barls...there is no security problems for release of the manuals etc....if anyone is afraid to copy etc send them to me and I'll do it.😎Uber Kafer wrote:to reduce an overvoltage problem on an alternator? dont think so.

So if the governor is doing its job maintaining the right speed, and apparently it is, and the volts are too high, I agree that regulation is the area to concentrate on. Anyway, after 20 years commissioning, testing maintaining, operating, (and sometimes breaking), alternators with a lot more zeros in the kVA rating, thats my 2 bobs worth.
JEP1957, As for the regulator control pot, assuming its the one labelled 'RAISE VOLTS' is there a part number marked on the body of the pot or any other markings? Equipment built to mil spec was always fairly robustly identified so it should have something still legible. I know its the most likely point of failure but you should be able to test it. But regardless, we still need the schematic in the public domain. Make fault finding a lot easier.

I'll see if i can get part numbers.

as for engine speed = alternator speed = Hz, then thats a no brainer for some of us.subimanx wrote:If you increase the engine speed the Hz will increase,as will the Volts generated.
But as for increased engine speed = increased volts, well thats a pretty basic/poor voltage regulator, and would have been a bit unstable on varying load. A decent regulator shouldnt really be affected by a couple of % rpm variation around 50Hz. I assumed it to regulate better that that, hence my earlier comment.
Anyway, thats what you have found on yours and I still havent run mine yet. Wait & see.

In my endeavours to find what is wrong with my generator i have come across a guy who has 15 of these generators for sale. He tells me 2 work fine, one overcharges like mine and the rest don't charge at all, so he is also looking for a cure for the overcharging problem. If anyone is interested in these generators I can email his contact number.

On another note, I got mine running yesterday for the first time. Runs beautiful, very quiet.
Good thing I persevered with the governor oil. I ended up buying a Nulon product, Hydraulic Fluid ISO 32. SAE10 equals ISO 32 on some charts, but I am not certain that the properties of Hydraulic fluid are ideal for the Governor. Open to suggestions from lubricant gurus. Anyway, the old oil that came out was rubbish.
Got one of the air cleaners, RYCO A256, which turns out to be stock size for an early Mini. Changed the oil, cleaned the screen filter. Set the valves. Cleaned out the fuel tank, got half a tonne of sludge n crap. that crap was right through the rest of the fuel system, but the carby still good. So its had quite a birthday.
Rolled the set out of the shed for a good solid run but then flooded it on restart... damn. By then it was beer-oclock so I left it.
Big run today hopefully.

As for an electric start, if you remove the fan belt and use the pully connected to a starter motor with the belt and a tensioner it will spin the engine over fast enough to start it, you need a far size starter motor without a nose cone, some English vehicles had these starter motors. Buy a V belt pulley mount it to the starter motor shaft, mount the starter motor to the frame, tension the belt by using a bar to lever the starter motor across and it should turn the engine over, remembering not to run it long without the fan running.
I plan toput an extra pulley out where the crank handle fits so i can start and run mine with fan still operating but don't forget you must be able to disconnect the belt from the starter motor as soon as the engine starts as the starter motors are not designed to continuously run. 🙂

I had to register to this forum so I could ask a couple of questions about that particular generator. I'm looking at buying a 10 kVa generator because I need a good powerful generator for an inverter welder. I have found one online and it is an ex army one, same as the one featured in this thread. Though someone replaced the VW engine with what looks like a Holden Barina (aka Opel Corsa)
My question relates to the alternator itself. It says it is a single phase 10kVa unit. But is it really?
I mean, it's it 1 phase where you can pull 30A or is it three separate circuits adding up to 10kVa?
The difference is crucial as I am working with a welder that requires 14A in use and spikes at 25A on start up.
I hope someone with electrical knowledge can answer that question as it could save me a thousand kilometers drive for nothing if it turns out being a 3 phases generator that only has 3 single phase plugs.
Thanks

On all the photos I can find on Internet, they always have the caps on. According to the manual that Volumex shared, the main outlet can supply the whole 10kVa but I can not work out what type of connection it is.
I was hoping that someone either has some details or photos of that main outlet (does it have 3 or more pins?)
Or that someone would know how the generator head is wound.
Thanks
Edit:
I just read this,
Chapter 1, section 1, paragraph 3:
" Four power outlets are provided for each of the two voltages available from the set. One power outlet, in each case, is capable of carrying the full output of the set, the other three outlets being standard pattern types, each capable of carrying a maximum of 3.5 kW of power. "
Doesn't sound good. That sounds like a three phase generator to me, unless the three standard pattern outputs are in phase with each other and can be connected together. A detailed photo of the control panel might be helpful.
AA003 ·
Three phase will do either if it has a neutral. (Star wound)
bendbau ·
I'm after a single phase, as in, two big wires (in a 10kVa, that amounts to about up to 41A) But I know that some generators are sold as single phase when in reality they are three phase 415V generators with the 240V outlets wired each between one line and the neutral. But then the issue is that you can only pull 3.5kVa from each phase, or about 13.8A (and even that is not good for the unit if you don't balance your phases)
