Not the best way to start the weekend. About 50 km into our ride on friday my buddy stops and says there is a weird noise when he brakes hard. I took it for a spin and it sounded like the track was skipping, went to accelerate and heard a horrid grinding noise and the track locked up. So had to ride back to the cottage to get the truck and trailer to pick it up.

Here are some pictures of the poor thing, anyone else have this happen to them?

Yep, it sucked to tow out. I'm sure it was from installing a longer track with stock Yamaha suspension. Unless you do something to correct the front suspension arm angle the track will tighten when the suspension is compressed.

god damn, looks like that thing just straight up snapped right down the middle, doesn't even look like there's any twist/fatigue marks in the shaft itself.
 
what year sled? there was a update yamaha did on the driveshafts, will look for info. for you.

gonna need a inner chaincase too.... :whine:

that sucks. I have broken a few of them right off at the splines, but not right dead center, but metal can do weird stuff, you just found the weak spot in the metal grain.
 
Drive shaft was out of a 2000 sxr 600 which I though was an updated stronger one. It's too bad it took out the chain case because I had a drive shaft in stock from a 2002 srx but not a chain case inner. Would appreciate any info on which shafts are stronger.
 
Had the same thing happen twice on my 98 srx 7 but the 6 has the origanal still in it.I blamed it on jumping with hard landings but after installing one out of a 2001 have not had anymore problems.

Tod at total rec in brechin will have lots.

Well apparently it's the 2001 and up drive shafts that are stronger. I will see if I can identify any differences when I pull it off tonight.
 
Well there were a few good hills on one trail but the rear of the sled wouldn't really leave the ground. But it was a nice smooth landing over them, don't know if that caused it but I'm sure it didn't help it.
 
that sucks, pretty much a unforseen event that could happen to anybody. i saw that the road was right there anyway couldof been a mile out in a trail with no ease of access with a truck. so at leat not much struggle getting it to the road i would consider that the lucky break after the fact of the bad news.
 
Here is some info I found on the different drive shafts, the older shaft has a chamfer on the speedo end where as the updated stronger version has a notch machined into the end of the shaft. Also the center drivers are a bit different between the two but the shaft looks the same otherwise.
