Sorry it is to bad about your sled, Did you get in on the class action law suit?
Look into the lemon laws in your state, Get your money back.
Another option call the BBB, They will lodge a complaint at the office in Minn. At least that way you get the ball rolling and get a paper trail started.
Make sure you contact your dealer for all the paper work he has on your sled, Updates as well as engine replacements.
I want in on the class action lawsuit my sled brok again today the starter clip pin broke causing my choke to move over and when i opened up my throttle it stuck wide open and almost hit a tree. Im pissed the only thing that saved me was the kill switch. Let me get some info on this Suit
Did you get a look at the whole piston, or just through the exhaust port?
Four corner seizure:
This piston has vertical seizure marks at four equally spaced points around the circumference. A four-corner seizure is caused when the piston expands faster than the cylinder and the clearance between the piston and cylinder is reduced. Another common problem of this type is a single point seizure on the center of the exhaust side of the piston. However this occurs only on cylinders with bridged exhaust ports. The main causes for this problem are too quick warm-up, too lean carb jetting (main jet), or too hot of a spark plug range.
This piston has many vertical seizure marks around the circumference. This cylinder was bored to a diameter that was too small for the piston. As soon as the engine started and the piston started its thermal expansion, the piston pressed up against the cylinder walls and seized. The optimum piston to cylinder wall clearances for different types of cylinders vary greatly. For example a 50cc composite plated cylinder can use a piston to cylinder wall clearance of .0015 inches, whereas a 1200cc steel-sleeved cylinder snowmobile set-up for grass drags will need between .0055 to .0075 inches. For the best recommendation on the optimum piston to cylinder clearance for your engine, look to the specs that come packaged with the piston or consult your factory service manual.
I think that Cat will have a little bit smaller pistons for the 04 season!!!
Rob, why would you be concerned about something like that at this point? You were never concerned before!?
By telling you not to call them at AC they ARE NOT SAYING THEY WILL NOT HELP YOU, but are instead telling you to deal through your dealer. AC has recently downsized their customer service dept but at the same time added more people to work with dealers to remidy your problems. Its up to the dealer to contact AC not yours.
