Cleaned up real nice for you...... Looks good :thumbsup: .......
About the crack...... its not all the way through?????? I would say your okay.... Is that at the top or the bottom??????? If it was me, i wouldn't be afraid to run it with that crack, but i would call up a snowmobile junk yard, and see if that have a cover, or a replaced part for cheap....
As for the scoring from the chain... Have you noticed riding the sled any banging at all??? If you have the chain tension maybe loose????? Just tighten it up??????? Then again I would rate my mechanic skills at about a C-..... :tongue:
the chain tension cant be adjusted on mine, its all by the springs. The crack is at the bottom and no it doesnt go all the way through. Also its not the cover. No i havent noticed any banging
I agree w/ snofrog, just get it welded.
As clean as everything is, it won't take much.
Good insurance, especially as the crack is on the bottom.
My best guess it that a chain failed at one time on that sled. That would explain the scoring on the inside, and the chain probably wadded up between the lower gear and inside of the case and stressed the lower part of the case - causing it to stress crack.
Casting flaw? That would be my guess too, based on the pics. Aluminum tends to cast that way quite often. Unless you know it took a recent hit, I suspect it may have been that way for awhile - if not since new. If it hasn't leaked, I wouldn't worry even if it is a crack. All that part of the case needs to do is contain the oil. It really provides little in the way of necessary structural strength.
Thats a crack caused by a broken chain wrapping around the lower sprocket some time. As said before a good weld (done by a good welder) will give you peace of mind. Check your current chain for stretch. That roller chain was a weak spot on those sleds.
Yup, I don't know why not. I am pretty sure it is just cast aluminum. I have welded stress cracks in transmission cases and output shaft housings. It can't be much different.
ok thanks for the replies. The picture doesnt do it justice. It IS a crack. My dad is a professional welder, been welding for more than 25 years, ill take it to him and get it done for free. :thumbsup:
before you weld it i would take a small drill bit and drill through the case at each end of the crack. this will almost ensure the crack won't grow after you weld it.

Never drill anything that holds oil or water on a sled ever, there is nothing wrong with that chain case cover . but now that you have took it apart put a new gastet on it . I have been watching your posts and it seems to me , that you are taken things apart just for something to do . Stop it , you will spend a ton to put it back together.
Hello everyone, I recently bought a 2015 polaris indy 550. I want your guys opinions on these sleds. I’ve heard the ones with the edge chassis were unreliable but I think the newer ones are more reliable correct?
We tried the group meeting last year and nobody showed but the breakfast was a hit. Anyone up for meeting again this year before the chaos begins? I will probably be coming up with Mark and Dave and going to Big Boy before we get there so if anyone wants to join us here is your invite.

I have a 2002 MXZ 700 RER Sport with Boysen reeds and MBRP can. I ride in temps from the teens to low 30”s too me it seems like it runs rich. What is my stock jetting and should the jetting be changed for the kids? If so to what?
I am sure the Thundercat is one....but what else is a fast sled.
I have a v-max 4, and now want something faster.
Please tell me what years to keep an eye out for also.
Thanks.
It wasn’t long ago that we were at the Wawa Motor Inn, just north of Sault Ste. Marie, sitting in front of a warm fire after a day of boondocking in Northern Ontario backcountry. Read More >>
