HWade Posted October 17, 2009 Share Posted October 17, 2009 (edited) I picked up this little onan generator the other day its an onan W3M its a 3 kva 230 volts. After a bit of messing about i got it going and it produces electric. Its built in a small cabbinet.The side covers are missing but these wont be to hard to biuld. I have started to strip it down now ready for the grit blaster. Will post a few more pics as and when i get it done.I will add pics as soon as I get them uploaded.

listerdiesel Posted October 26, 2009 Share Posted October 26, 2009 (edited) Here's one of ours. The pictures were taken before we took off the angle irom framing and did the exhaust. The nameplate gives the engine year of manufacture. 75.235182 is July 1945, the first digits before the period. The basic manual is on our websites in the Onan section. The thread on what we did with it is here: http://www.stationary-engine.net/forum/showthread.php?t=4425 Peter Edited October 26, 2009 by listerdiesel Quote Link to comment Share on other sites More sharing options...
HWade Posted October 26, 2009 Author Share Posted October 26, 2009 Hello Listerdiesel, Thats a nice looking little genny you have there, the thing I like about these gennys is how quiet running they are. Thanks Howard Quote Link to comment Share on other sites More sharing options...
listerdiesel Posted October 27, 2009 Share Posted October 27, 2009 (edited) The new exhaust is an Onan one that is now vertical. We had some flanges laser cut to suit the mounting on the cylinder block, and welded some 1" BSP swept bends in to make the 'manifold', We also fitted a stainless steel band around the top half of the silencer with a stay going down to the carb/aircleaner bracket. So it finished up like the pictures below. Magneto points and capacitors can be got from Rudy Adrian in the USA, KLG plugs or NGK A6 work OK.

HWade Posted October 29, 2009 Author Share Posted October 29, 2009 Hello Listerdiesel They made a nice job of the exhaust flanges, I dont suppose you had any spares cut and want to sell one.The silencer you used looks like the ones that are used with the CCK 3.5 kva ex British Army.You have made a nice job of that.Because mine is in a small cabinet I think i will put on a quick realease type fitting, as used on the cck gennys.it is suppose to have an pancake exhaust muffler but this i would have to make dont think i would get an original part now.

Regards Howard Yes, we had some spares done, and it is indeed the CCK silencer, we had a load of that stuff around when we bought our crated/overhauled 3.5 from Rosyth. The CCK silencers "don't", they are very noisy! Drop me a PM with your address and I'll sort a flange out, I can't remember what we paid, but I can check back.

Thanks Howard Whats the difference ? the CCK 3.5Kw has the same output but is completely a different shape, what years do they date from. My CCK is pretty quiet considering it can chuck out 13 Amps all day at 1500 RPM, bit on the heavy side though do like it lots better than the "modern gennys" Quote Link to comment Share on other sites More sharing options...
listerdiesel Posted October 30, 2009 Share Posted October 30, 2009 The W3S was a water-cooled wartime unit, made before Onan went into air-cooled engines full time. earliest I have seen is 1942, all of ours are early to mid 1940's. They were sold as Fairbanks-Morse units and also as Montgomery-Ward. There was a single-cylinder variant that is fairly rare. The CCK and the variants it spawned was the basis of Onan's post-war sales, but the W3S is a nice unit and easy to work on, and nowhere near as mechanically 'chattery' as the CCK. Being cast-iron everywhere, including the radiator casing, it is also a fair bit heavier! Peter Quote Link to comment Share on other sites More sharing options...
listerdiesel Posted October 30, 2009 Share Posted October 30, 2009 That is the earlier one with the float oil level indicator and the rear-mounted magneto. One of mine is identical. Nice to see the primered block etc., never had any of mine stripped that far down yet. One of ours was donated by a family where the husband was incapacitated, so we promised to look after it and not sell it on. The red one we bought on ebay, another one (the early one) was down to a chance spotting of a W3S at an engine show, and the owner said he had the 'remains' of another one at home, and the last one we bought off a guy on our engine forum.

HWade Posted November 5, 2009 Author Share Posted November 5, 2009 I had some spare time today, I managed to collect the radiator and get it fitted back to the generator,they made a nice job of putting in the new core,After a bit of time fitting, the water was added and she was fired up.Great stuff no leaks anywhere.Now got to get the cabinet rebuilt as and when I find time.Heres a couple of pics with the radiator back on.

R Cubed Posted November 5, 2009 Share Posted November 5, 2009 Hi Howard, the generator looks neat, is the colour of the genny the same as your GMC ? if so would you be willing to divulge the type of colour !!!!!! Quote Link to comment Share on other sites More sharing options...
HWade Posted November 5, 2009 Author Share Posted November 5, 2009 hi, yes i have used the same colour from the same batch of paint,and the last tin I am putting an order togeather for some more paint.The colour is an olive drab that some friends of mine use on there US vehicles that the British used during the 40s.The funny thing is the last batch i got was called landrover green, I dont know why because its nothing like it.I know it takes them a while to batch it because they have to taken out the gloss. The paint I use is not a matt finish but more of a sheen finish. you can also use a standard thinner with it. If you are interested I can let you know the price as soon as i give them a ring for a price.The last lot was £35 for 5 litres.

listerdiesel Posted November 6, 2009 Share Posted November 6, 2009 Nice one, looking very good now. Is that a Rapidor hacksaw I see in the background? Peter Quote Link to comment Share on other sites More sharing options...
HWade Posted November 6, 2009 Author Share Posted November 6, 2009 Hello Peter, thanks for that, in reply to the hacksaw I think that is the make, i picked it up from an army surplus store there was 3 2 of them were 3 phase and the one i have was single phase. Heres a couple more pics of the genny i got a bit more done today.Please dont take to much notice of the exhaust it just temporary untill i get the correct one made up.

I like the slow dependable generators bit on the juicy side though, but when you want it to start you know it will and probably will for ever. Long live cast iron bits.......bits always come undone. Poo poo to ally.... here to day gone tomorrow. Quote Link to comment Share on other sites More sharing options...
listerdiesel Posted November 7, 2009 Share Posted November 7, 2009 1500rpm for 50hz and 1800rpm for 60hz. CCK's can be those speeds or 3000/3600 for higher (5kVA) output. Peter Quote Link to comment Share on other sites More sharing options...
JEEP 44 Posted November 9, 2009 Share Posted November 9, 2009 (edited) Hello Howard, you have made a nice job of the genny.
