Drive shaft collar comparison

[geo]

Look what we had here in Russia last weekend! The problem is in THE GLUE!!!

So the best way to fix the issue is that very new collar (IMO)!!!

S**ty thing to see happen but great pic to prove-disprove guesses as to the failure reason.

Analogy of poor quality socket and whether the tunnel is enough to hold the shaft in one piece is maybe out. Maybe poor bonding is simply the issue.

I know one thing, I ordered an extra clamp for just this pic. I`ll be using 6 Team helix bolts and tig-tacking a plate to make a lip onto the extra one for my sled.

Eventually Poo will do what needs to be done. Until then it`s a lipped clamp for me just in case my glue didn't dry.

gonna put my faith in the happy face clamp. the polaris clamp is weak imo.

Someone correct me if I'm wrong, I havn't had a Polaris clamp in my hand to look at, but in the install pics it looks like the gap between the 2 clamp halves is pinching down on the ridge of the driveshaft. It seems to me this is preventing the 2 halves from clamping "tight" around the shaft. Can it be clocked one "flat" from where it is in the picture so this ridge doesn't take the pressure that SHOULD be going around the shaft?? this would explain why some are creeping out on the shaft and allowing failures.
Aren't those machined notches supposed to go over the ridges???
Just an observation.....I'm probably wrong.

Sure looks like it....clamps right down on the ridge. Its pretty obvious that this happy face clamp blows away the polaris design. I just glued my happy face clamp on with Lord 406 adhesive, hoping i will never have to worry about it again.

it is possible that the other bolt is threaded in more in the sample pic and that the clamp is capable of being centered yet to crouch over that rib...but i would like to see a relief in the clamp body in that area for the ridge as well..

not trying to defend the Polaris clamp,just saying it may not be resting right in the picture,.

i think the best set up is the Happy Face and with any addition of glue or bonding options is just icing on the cake...!!!


Wiliikers...looking at the Polaris pic again the reliefs seen to be lined up on all the other ridges so the clamping area at the bolt sure does seem strange...
do some of the bolt threads remain exposed..??..i can understand a very small gap to be the end result there but it looks like it would be substantial...wth..??

Yada, did it damage the tunnel on the clutch side when it climbed out of the clamp? Sucks for sure, and is why I would run a lipped clamp with GLUE....

YADA.... Not sure what the dimensions are on your collar... what kind of fit does it have? if it was not tight enough... I can see where it would promote camming out of the shaft.

What does the opposite end of the shaft and the flange inside of the clutch area look like?

The Polaris collar fit IS designed to apply significant force to the shaft area.

Time will tell what happens on these sleds with all the different collars out there!!

Mountainhorse is on the money, Polaris is saying that the clamp should cover only the area where the metal end cap is and nothing more.

the only thing I could see about other clamps is if a failure starts to occur you may beable to get the sled out of the mountains under its own power.

 

[mountainhorse]

IMO... it has more to do with the fit and strength.... but if there is not enough clamping pressure and resistance to deformation that would allow the stub from exiting the shaft/collar assembly... then there would be trouble.

The H.F. collar seems to fit extremely well (I've installed 2) and contain the stub as well should it start to move.

where did ALL the pics go?
