SA 200 Year?

admin

I just purchased a SA 200 Lincoln. The code is 9053, when I check it on Lincolns site the best I could come up with was 1987. The serial number is A-1069966, with this I cant find any place that has this number. Does anyone know what year this machine is for sure? By the way it runs and welds great. Purchase price 650.00 on factory lincoln trailer with 200' of lead, pretty good deal I hope.  Thanks

Reply:BobC, Do you know if this one would have the aluminum coils or copper?  Also this is a DC machine right not a AC/DC.Last edited by 63 Max; 01-01-2008 at 10:53 AM.
Reply:Not sure on aluminum or copper but, the machine is DC even the 110 side. Check your power tools before you plug them in. An AC tool will be rendered useless after using DC to power them
Reply:The stator coils on that machine would be aluminum.  They switched from copper to aluminum in the early 1970s.  Lincoln went back to all copper when the Classic I replaced the SA-200.One way to tell is from the shape of the generator.  A main generator frame that is round will have copper coils, one that is octagon shaped will have some aluminum coils.To the best of my knowledge, the armatures have always been all copper.Bob

Reply:There are a lot of aluminum wound SA-200s on pipelines and yours has apparently been working fine for more than 20 years.  The design isn't all that prone to breakdowns, but if you're concerned, you should have a good, experienced repair technician carefully check it over.  Any machine can break down, even new ones have problems sometimes.Good luck,Bob
Reply:Here's a pic from when I picked it up. I have taken all the sheet metal off and sand blasted it and primed it. I also purchased all new plugs, wires, thermastac, hoses (fuel, rad, overflow) got oil pressure & water temp gauge also. I power washed the unit after the sheet metal was off. Cleaned it all up and painted it. As soon as I get the sheet metal all painted I will post some better pic's.Can't figure out how to upload the pic, can someone help with this. ThanksLast edited by 63 Max; 01-14-2008 at 02:46 AM.
Reply:Pic when I got it home. The pic was to large to upload. Attached Images
Reply:Pic of how it looks after I took it apart, sanded and painted, and replaced all hoses & belts, clamps, added temp & oil pressure gauge, clear fuel filter, spark plugs & wires, I also added a brass ball valve with a hose nipple on it to change the oil easy when it's on my truck. I think it turned out pretty good for the first one I did. Attached ImagesLast edited by 63 Max; 01-16-2008 at 01:55 AM.
Reply:Pic of the valve to change the oil. Just under the air cleaner you can see the hole the hose goes through then just open the valve and drain the oil. Attached Images

Reply:In 73 and 74 Lincoln tried going with Aluminum SHUNT field coils. The following (I hope) are pics of 3 different generator housings. ALL are constructed the same inside, except the 73 has aluminum shunt field coils. Illustrated 64 housing:  73 housing  52 housing I hope this helps.
Reply:Hey 63 Max you sure did a nice job on your welder. I am redoing a P&H welder with the F140 continental. It would seem that a lot of engine driven were built using continental engines. Keep on it and from what I've seen and been told they will last forever.
Reply:more pic's of the 86. check out my next project on another post, it's a 57 shorthood. the pic's say shorthood but i took them the same time i took the shorthood pic's Attached Images
