Gotta love that rivet job. Hope he gets warranty. Hope Polaris steps up to the plate for him. It is modified now.

saw that in person years back, just cruizin down the trail and boom!
Anyway, was by the local dealer today. Had a demo there from last spring and it had the older extruded shaft. FYI.
Although I really want to believe that this is caused by a batch of faulty assembled driveshafts, I'm getting worried.. Seems like the "bad ones" break real fast, but I'm with winterbrew and others here on the design of this shaft.
I don't believe glue, as a method of assembly in motorized vehicles, is suspect, but the overall size/strength/dimension thing here... Guess I'll just have to admit that these pictures have an effect on me?
I think Kelsey's kit and others will help a lot, but not enough. That short steel stub just seems more and more like a demonstration of leverage physics.
Remember slip-sprockets from sno-X? To save steel chains from breaking.
Sorry for my low-fate reply. Only upside I have to counter with is that if my thoughts are correct, Polaris will have to replace the shafts.
lol...I was waiting for someone to bring this up...Just read it in the paper over the weekend. Nice call.

that was the funniest fricken thing i have watched in a long time
Aluminum Drive shaft
Another possibility is that the aluminum used in the drive shaft, is not up to specifications. Does anyone know if the drive shafts are made from an outside vendor. It just maybe a bad batch of metal or the extrusions caused the metal to fatigue. Weakening the end of the drive shaft.

Any 2013 pro owners needed helicoptered out??
If so will Polaris be helping you recover the cost?

What a great video, alot of anger there, especially loved his sound effects. Funny as hell, except for the stranded part, thats not funny at all. When these machines fail they can leave you in SERIOUS trouble. Thats what I have an issue with, a brand new sled leaving you stranded.
Just got this on my phone....not even sure who's it is. I think one of our customers.
THANKYOU !!!!! AND SO THE REAL TRUTH FINALLY COMES OUT! THE DEMO SLEDS DID NOT HAVE THE 3 PIECE BONDED DRIVESHAFT !!!!!!!!!!!!!!!!!
Poloris sent out those 3- piece driveshafts essentially UNTESTED. Pro RMK owners unknowingly volunteered themselves to be guinea pigs and proof test those driveshafts on their sleds and on their dime, or dimes as the case may be ! I'm shocked! Absolutely shocked!
As a further thought on bonded driveshafts being used in automobiles, my auto driveshaft is under no stress whatsoever, when the vehicle is not running. A snowmobile driveshaft on the other hand, is constanting working because they maintain the considerable track tension. The Pro RMK belt drive driveshafts, are under an additional load that chaincase models are not, because the belt drive has to be continuously in tension in order to stay on the gears. The combination of those two perpetual forces on the bonded joint, allows it no chance to rest. The glue is always working and stretching. And then the cantilever moment from the engine torque lifting up on the belt drive gear fastened to the end of the driveshaft. It just keeps getting worse and worse. The triple storm of internal forces that are unique to the Pro RMK, all come together at the same time. And then POW!!!
It looks like the rider thought that he was trenching at the time, and kept the gas on in order to get him out of the ditch.

hopefully those in denial about this are beginning to realize that this is a huge engineering fu*k up by polaris. this is ridiculous, it doesent take an engineer to look at this driveshaft and laugh at the design failure. It poses a huge safety hazard. Apparently polaris needs to be forced into taking action. THOSE WHO HAVE HAD DRIVESHAFT FAILURES SHOULD FILL OUT THIS REPORT ASAP!! here is the link to file the Consumer Product Safety Commission report:

--Isolated to the Pro RMK only(all of them)
--If you have a 13 Pro, you have a problem(till fixed)
I am going out on a limb.....no. Especially after they test your fuel and find ethanol....warranty void!

awful knawful

don't the sleds have ethanol plug?........

my gramma serves up a killer free hotdog lunch with every pre paid pootow.
My buddy 450kid and I put about 80 hard miles in two feet of powder on ours this weekend. Sure glad we did not wait for Polaris to fix the problem. All we had to worry about was getting the clutching done on ours. You guys waiting for Polaris, plan on spring riding (if your lucky). Ours are hauling ***.
I GOT IT I GOT IT !! You want to hear it ?! It's what I was ranting about a couple of years ago ............ READY ?! ............... It's that center extrovert climbing in between the track windows putting extreme pressure on the already to tight of a track TADAHH ............... NO ?
