I have a '14 pro 800 163, I just noticed a hairline crack by the bolts where the a-arms bolt to the cast aluminum on each side. Has anyone experienced this? Is it covered under warranty?
Thanks

Yes there are hairline cracks right by the bolts, no damage to anything else.
Kinda hard to see
Good dealer will help a lot. Could be a casting weakness, either pour or mold itself.
FWIW, I've taken out lower a-arms, both sides, on multiple pro RMKs, and have never seen a crack in the upper casting. Never trashed an upper. Bulkhead is much tougher than the Rev and XP doos I've had. Good luck.

Yo man, i had basically the same thing. just in a little different location. Dealer told me they wouldn't worry to much about it and to have a weld shop throw a bead on there. Did that last fall and it held up fine all winter. I say throw a bead on it. Just me .02cents
A plate with lords and rivets would be stronger........
I've welded a bunch of cast aluminum with varying sucess....

I've had numerous cracks welded on cast aluminum parts of the Pro chassis and they never rebroke in the same spot. I'd weld it up.
Are you sure they are not just marks from casting? Just a thought.....
I've seen several cast items with the same type of mark, which were not hairline cracks.
Have you done anything to prove they are cracks? (Dye/Paint/Marker)?
The heat affected zone around the weld becomes soft.
Less prone to crack but weaker nonetheless.
Some of the Polaris castings Weld absolutely terrible. We have been welding some CFI engine cases lately and they are horrible. But the cylinder welds amazingly clean since it's cast by a different company. Haven't played with the bulkhead sides too much, if they are cast by the same company that does the case I'd just replace the bulkhead side. They are relatively inexpensive and easily replaced.

Had my dealer look at it, he thought that it might just be casting marks. Since I have warranty till Dec. of 2017 he said mark the outside edges and see if it gets bigger after next season to know for sure. So I guess I will wait and see. Thanks for all the input.
