2013vs2012 shaft weight

[Thistledoo]

Ok I just weighed both shafts both with 3 drivers and the pto brg installed

2013. 6.4 lbs

2012. 7.0 lbs

Can u believe this? This is what my hanging scale said.

All this headache for less than one lb? Are u serious Polaris?.

Anyhow rant over I'm glad I snagged a 2012 shaft when I did.

How about for a recall fire up the plant where these steel shafts came from??

.6 lbs of rotating mass actually is quite a bit. Especially when the shaft is as large as the pro shafts. The weight is further from the center of the shaft causing an affect of it being more noticeable.

On a side note, that .6 lbs had to be reduced 26 times on that sled to get it to the weight it's at over last year. It's not like they just took off one or two parts to drop that 14 lbs. it had to come in little bits from here or there.

I know there's a lot of bummed Polaris customers and I'm sure you all will get taken care of when they find out why/how it happened (I FIRMLY believe it's a manufacturing error not a design error) and release a fix. But I'm stoked that they are spending the time, effort, and money to re-engineer, re-analyze, re-test, and re-tool for "just .6 lbs".

At least you have a sled to put the 2012 shaft on!!!

I would bet $$ that snow and ice will build up easier on the aluminum shaft and on the hill, the new aluminum shaft is heavier.
Drivetrain is the LAST area I would want to cut weight/strength....and crankshafts.....please don't try a glued aluminum crankshaft.

Cat did very well with the light weight crank shaft! But on the other hand, that is a suzuki engine....

M1k,

I agree with you... they DID go through a lot of expense and effort to drop a little weight which is super cool for raising the bar.

I also agree ... IMO... the design of the shaft is not faulty... but rather a MFG error... It will be interesting to see what/if a "new" shaft would have changed, but that would require someone to cut open a new replacement at their own expense as I'm sure that Polaris will be guarding any changes in specs.

...And on the weight diff of the shafts... the drivers are different and may account for that... I wonder what the weight is if the shafts alone.

To me, the rotating mass of the shaft is pretty close to the centerline..probably about 1.75" or so in radius... not much... There may be a calculated difference.. but how much?

I can tell you all that the day I spent with the Demo 2013's going back/forth with the 12's that that 13's felt different in the way they handled, especially how they got on edge and stayed there with less effort.

Hmm.... Good topic.

.6 lbs = 18oz = so many mg. lol WOW

I had the same thoughts about it also!!

I agree with you mountainhorse 100%, on the error of the MFG's part.
I like what polaris is doing, because every OZ. they can trim from the drive train is why this sled is what it is, in the market today. The most FLICKABLE sled out there. Thus for us that like the technical riding end of sledding, this is what we want.

What I would like to see Polaris do, is put a little more attention to the venders quality. IMO

Thanks Polaris, keep pushing the edge!!

Stirring the pot once again. And you dont even own or ride a 13 Pro.

Seems like the norm lately, Winterbrew is a positive helpful source of info in the Doo section, but now every post I read in the Pro section Brew has a negative opinion.

Would be refreshing if you would positively contribute here like you doo in the Skidoo section.

 

[winter brew]

That was positive.
I will probably get as much time on our shops 13 Pro and I did on the 12.
I promise to post pictures of whatever brand of sled gets towed out.....I admit I will post them quicker and with more enthusiasm if the Doo gets to tow out the Poo. Hopefully they get the issues handled and we ALL have a trouble free, safe season.

I know this has been covered, in another thread.

If you put the QD belt on a 12 pro, does a new drive shaft come with the kit?
