Viper Cross-Shaft shears...

[yamamarc]

Those with the RTX LE sleds already have the beefier parts just FYI.

The RR skid has the adjustable reservoir shocks and is easily identified by 2 pr of wheels outboard the rails in the front of the skid.

I remove my post it wasn't accurate after double checking both my rtx se and wife's zr 7000limited shafts mesure .637"

What are the actual diameters of the 2 shafts?

Looking at the pics the "tell" us that the shaft OD matches the bushing OD. If the shaft is smaller OD than the bushings then it is not the HD one.

No. I think that is how much it flex's then comes back. That amount of wear took a long time. Never took a straightedge under there but would have seen the bolts cocked in tunnel if shaft was actually bent before. I think it flex's then fails. Have seen bent ones but I believe those were bent just by hitting the rod putting suspension in. It is exactly like a tierod in every dimension. Doesnt take much of a hit to bend a tierod.

Sounds logical. So when inspecting our suspensions (I remove mine at least once seasonally) if that rubber isolator looks to be "tapered", it'd be a good idea to upgrade that shaft to the HD version?

Yes. Not a bad idea to do it either way. You never know. You know. Still undecided if I should just not run the isolator.

LE,RR=.765
Stock=.625

Just looked at the support plates on the tunnel and they are starting to bow out? Hardly much yet but should I be concerned? On the right side paint is chipped off of the tunnel around one of the support rivets.

If its those self piercing rivets then yes for sure get the bigger shaft in there.

14 ltx just over 4000 miles broke front arm shaft last weekend
After some very rough trails

Tunnel damaged?

Well pounded the crap out of my sled in Michigan the last weekend and appears to be no more damage.... hasn't bent more than it already has. strange. I am hoping I will not have this problem get any worse.

Did you put the bigger shaft in?

Tunnel damaged?

Tunnels a little bent at the bolt holes but not major. Going to machine up a new steel shaft at work.

Before you do anything please bring it to dealer or at least take pics and ensure they file a warranty claim. Yamaha needs to be made aware in the very least. This will help others for sure.

i had a 1998 zl-500 cat that the long bolt runing from side to side on the bottom of the front arm broke inside and was hanging out clicking on the inside the tunnel so i pushed it it back in and the ice held it in till i got back to camp dealer was surprised but installed a new one and really greesed it well if that slid out lower front arm would have jammed up the track
