I guess this is an introduction of sorts. I just picked up my first sled, a 99 Indy 500 xc... for free. Its in decent shape, but the motor is blown. as far as i can tell, the connecting rod snapped, and spit the crank case. seems like a lot of work, but i couldn't beat the price nor the challenge. If anyone has any advice or resources for me i would be very grateful! Any diagrams or specific information on the engine would be very helpful!

Specifics:
Polaris
Indy 500 XC
Model # 099SB5AS

Thanks in advance!

Welcome to the forum. Advise is to go buy a new engine. You should be out the door right at anywhere from $500 to $1000. Depending if you do it yourself and how frugal you are in your parts scrounging. Best of luck. That can be a great machine.

No such thing as a free sled

Welcome to the forum! You sometimes can find engines on ebay for pretty cheap. Al's Snowmobile Parts Warehouse - Snowmobile Parts, Snowmobile Parts, and More Snowmobile Parts is another place to buy used parts. Al's is a used part warehouse and is good to work with.

Good luck on your project!

Skid

Don't hear of a lot of snapped connecting rods. Usually see cooked pistons or crankshaft bearing damage. Replacing the engine is probably your easiest and cheapest route. Ebay, CraigsList, or salvage yards are your best resources depending on where your located. Regardless, I suggest you also rebuild the carbs and make sure the jets and primary clutch weights and springs are stock if you expect it to last. Many people exchange longevity for performance and end up with engine damage.
Welcome to the forum...and the snowmobiling addiction.

If this sled has the Fuji 488 liquid cooled engine in it, Polaris put these in a million different sleds, so look for one that was wrecked on Craiglist or ebay. The 440 liquid cooled motor will most likely work too, just not as much power (obviously). The cranks are the same on the 440 LC & 488 fan motors. I have 3 of these sleds and they're great, as long as they get oil. I rebuilt 2 of these. One was an oil pump went bad and the other the crank bearings rusted when a guy stored the sled outside.

Good luck!

Its wierd that the connecting shaft is broke. Usually a piston arm goes or a baked cylinder. Thats what happened to my sled in my profile pic. But if your not familiar with snowmobile engines or engines in general buy the liquid cooled 500 non-fuji engine. More reliable
