I have a Powerline 12/1 with counter balance weights on the crank. I bought this new last winter. I disassembled it, cleaned it, had the crank polished and put new rod bearing in it. I even painted it with Gyptal. I put everything back together and cranked it up. A little jumpy on the wood 6x6's ,not at full rpm's, but I just wanted to see if it would run. It did. I finally got the framing done and the generator mount finished. Bolted everything together and it looked good. Got around to pouring a 3x5x2 foot block of concrete to mount it on the beginning of this winter. After everything was bolted and welded down i ran it and set the rpm with a laser tach. Rpm not quite 980 on the engine and 1800 on the 7.5kw generator. I have got to run it about 5 to 6 times for about 2 to 3 hours at a time. The problem that I have noticed is vibration, a lot of vibration. It is so bad that I can see the 4500 pound block of concrete move a little. Everything is shaking on this thing, although not violently. It has even shaken the rubber of the fuel tank straps and broken welds on the frame mounts.
I had hoped to use this unit to power our off grid home this winter when the solar panels could not keep up. But I have decided not to run it until I can get the vibration under control. I'm afraid that some major will brake on the engine besides some of the welds on the frame.
Can anyone help me get the vibration under control ?
I have tried to post picts but they dont seem to come up. I have them in the listerenginegallery under mike.
