My 543a2 fired up today!!!!! I have been messing with it for a week and a half. If you don't know, it was under water in Iowa for a few days. It came with 1 gal of water in the pan and 22 gals in the fuel tank and lines. Got it all out, took the starter out and freed it up, put it back in and it almost killed me. that thing weighs a ton. 2 new batts, rolled it down hill to check the engine was free. Reinstalled 3 injecters and hooked up all the lines. shot some either and it poped. Drained all the fuel filiters and lines, finally had fuel and not h2o everywhere. 3 shots of either and it came to life!!!!!!!!!!!!!!!!!!!..Drove it around the yard a little. clutch needs adjusted, spent awhile on that and it's still not perfect. After tracing linkages and ptos for awhile i got the front winch going and i got the hoist going!!!!....All controls work great, it winch, hoist goes up and down as does the boom,...boom extends and retracts and the whole thing swivels left and right, very smoothly also,....i never found evidence of water in the hydrolic fluid..I AM PUMPED!!!! Thanks to those that answered my stupid questions in PMs, and those selling accs.. stupid question, does the boom extension have a stop, i don't want it comming out of the end. Thanks to all and this GREAT site. I also need a new rear drag winch if anybody has 1....
