Went riding for first time this season on hard packed snow. Both our 2000 Powder Specials had tracks seize up on us. The 600 seized after only 2-3 miles of riding the 500 was after about 20 miles. Dealer told us it was the conditions - not enough snow to cool them. Didn't have problems last year and rode on similar conditions part of the time. Any advice?
Take a look at the sliders, do they look melted? Is there plastic stuck to the track clips? If so, they weren't being lubricated sufficiently. If you ride in marginal snow alot maybe they offer additional wheel kits for your sleds.
If you hit those conditions often you should consider putting some ice scratchers on your sleds. They will throw ice chips back into the suspension to allow the sliders to get the lubrication needed so they won't melt and stick to the wear clips on the track. I cheaped out and installed a 3/8 x 1.75" bolt into the back inside corner of each ski to spray ice chips onto the skidframe. Just drill a hole in the ski and put the bolt in. They don't have to contact the ground when it is sitting on a solid surface but will hit the snow on the trail every once in a while. It works good. If you want to buy the real ice scratchers you can get them from SLP or Holz Racing Products. Theirs are spring loaded so you can move them up and off the snow if not required. At the very least try to get into some soft snow beside the trail or stop and kick some snow into skidframe every so often.
