Default 2002 polaris 550 motor problems

Bought 2 new back in 2002. 1st one we gone thew 3 top end rebuilds, 2nd one i was riding saturday and blew the motor. only 1300 miles on the sled.i just found this site and read others had same problem. did anybody get any help from the dealer? how do i go about getting this fixxed right the 1st time. does any also know if a 600 motor will fit in and all other motor parts will adapt? i would rather put money into a better reliable motor.

It's doubtful that a dealer will handle your problem at this point. The problem was not uncommon with the early 550s in places where 1300 miles was a small part of the first season's use - as it was in rural Alaska. A liquid cooled motor does not easily drop into a fan sled without extensive additions. You could upgrade your engine, I think, simply by having the newer nicasil cylinders and corresponding pistons put on it. That's a rather spendy investment, but one which would probably serve you well. I have the same engine in an '01 machine. I have been into it for rebuild purposes three times. I think it may be good finally. I have just been rebuilding as original and have gotten about 3000 miles out of the last work. It presently has just over 8500 miles on it.

I'm not hearing horrible things about the new Polaris 550s. However, that does little to take the sting from those who have been bitten by failures in older versions.

I have written Polaris numerous times about their void in the smaller horsepower fan segment enumerating the virtues of the old reliable engines they once powered with. Apparently it must be embarrassing to them that they replaced what was good with something as faulty as the 550. (I suspect that their embarrassment may be grounded in their failure to do the proper R&D, leaving that, instead, to be done by their customers.)

In any case, though I've managed to squeeze over 8000 miles from my 2001 Supersport - because of three top ends that I have been competent to do, I still do not regard these 550s as trustworthy (or cost-effective) machines. And when I go into caribou country in a couple of weeks, I believe it will be the very old, worn 488 fan which goes, rather than the well-running 550 which has 1/3 as many miles.

There is lots of good stuff there. The Snowest site is a long thread but very thorough and insightful (perhaps inciteful too.)

Default ANOTHER 550 bites the dust

Up riding in Old Forge area Sat. with my 05 2 place touring deluxe with my rebuilt engine from last Winter at 1200 miles.Now at 1400 miles,did 50 miles,going fairly slow 25-30 mph. and that terrible same weird noise and feeling came back.The engine shut down the first time,but I did restart it and went as fast as I dared to get closer to civilization.I only made it about 1/2 a mile and she seized up.I got a tow from a crotch rocket type sled with matching driver{18 or so,no fear type--fun ride]for about a mile.This is absolute BS,last year Polaris picked up all the parts{app. $1,500} and I had to pay $175 or so for my dealer's labor.Now,just 200 miles on their rebuild,we'll see what they say when I roll in there this morning.I definitely want that Nicasil upgrade kit at minimum, and on them.

I feel badly for those who purchased these sleds in the past. Ironically I was trying to talk my son into buying one for his wife but after reading through the forums on here and Snowest I am glad we never did buy one. Thanks to all of you who have shared your troubles with the rest of us. I think Arctic Cat or Skidoo is the way to go for her. Polaris has clearly dropped the ball on this and as a consequence they deserve to lose any market share they had in this segment.

Yep. I don't know why they changed a formula that was so proven. In my view, Polaris had some of the most reliable yet simple fan engines going. Why change the formula so radically? I do like the new stout case design that the 550 has with the whole stator end casting that goes on and off in one piece. But why change so many things at once. What would the engine have looked and performed like if they had just built the new case, updated the shrouding with injection molded plastics as they did, and added reeds to their 440 and 488 engines. I'm thinking that might have been an answer to "more" that they wanted to create. Or what about building the higher displacement motor but without the herky-jerky "performance enhancements" of the reeds? I wonder if anyone has played with these 550s without the reeds or with altered reeds?

I know I still don't heartily recommend machines with the 550s to people without some prejudice. It is just difficult to find confidence in an engine that has need so much ongoing R&D in it first ten years on the market.

Look on the bright side we could have been worse off if we bought a fusion 900 or one of the new 800's.They're all junk.Why can't polaris build a reliable engine anymore??Who wants to buy the first new RUSH raise your hand
