I blown my motor this winter, I just found I have 2 different cylinder on my sled, One has 3021866 on the side, this one is ok, the other one has 3021767 This one piss me off the skirt is broken.
Witch one is the right one for my sled. 2008 RMK 700 155.
Send your cylinder to Millennium Technologies or US Chrome and it will come back good as new for about half the cost of a new one. Send them a new piston and they will fit the piston to the reconditioned cylinder, as well. I broke the skirt off my 700 last season and Millennium fixed it up, no problem. It's amazing what they can do. My broke cylinder was also the 3021767, it's likely they went to a slightly different design for better longevity. That's a guess, mind you.
I'm not sure who you would send to north of the border... you might call one of the dealers to see where reputable repair facilities are located if you don't want to send your stuff south.
If you look up the number on the Polaris website, the 3021767 part was used in the 2007 and early 2008 sleds. The other part number is used on the 2008 700 sleds and the 2009 and 2010 RMK 700. It's likely that your sled was built when they were making the transition to the new part and they used what cylinders they had on hand.
It's similar to the Indy and GenII 700 with the 220 and 824 cylinders. You can't get the 220 cylinder now, if you order one, they ship you an 824.
I have never seen a cylinder skirt to break like the one in the pic but I do have seen many pistons skirt to break. Thats a weird thing to see it happened - WL
The big thing in this case is , I don't just need a cylinder and piston but a new crankase and a new crankshaft. all of this will cost me 1400 .. yeah!!!!!!!!!!
Here's what mine looked like... and the cylinder back from MT at the end...
Broke piston
Broke crankcase
Broke Cylinder
Same cylinder after repair by Millennium Technologies
How many miles (km?) were on the sled? I've been reading that replacement of the pistons at around 3000 miles (4800 km) may keep the piston from breaking. I know if I keep my 700 that it gets new pistons if I ever find enough snow to ride that many miles.
The guys From MT wont repair it, I have to replace them. My motor look like your.
I thing I have 3900 miles, and I run maybe only 400 mile on this and just 80 Miles this winter. I blown my motor just after I pay for my plate and my trail pass. plate are almost 90$ and the trail pass is 360$ YEAH!!!!!!
