Track shaft bearings - chain case side

[jonlafon1]

Amount of power doesn't contribute a thing to the bearing spinning on the shaft. Does not matter if its a 100 HP or 1000 HP, the bearing needs locked to the shaft plain and simple. It's clearly a case or poor engineering, lack of testing and a blatant disregard to improve the poor design over 8 years of production. This whole Cat driveline is a disaster!

Imagine what it has cost them for warranty! No wonder Cat and now Textron/Yamaha is teetering on the edge and dead last in sales. If they can't be build them better than this in 2020 they deserve to go under.

Okay why is this spinning on the shaft not nearly as common on lower hp sleds?

It is common. Happens with the low HP stock Vipers as well. Same as the Sidewinders.

I do maintenance on a couples sled and it’s definitely worst on hight HP sled....

I have that bad feeling too. Especially since Yamaha is a self funded warranty unlike Cat. This year the demons are going to haunt them. LE center shocks,Driveshafts and chain cases along with tunnels from pos slide action shaft. It’s got to be a lot of $.

Really? Because the Viper forum is loaded with just as many shaft failures. They had failures just like we're finding on the Winders now, long before the Winder even came to market! Same exact wear on the shaft.

IMO, there is a reason the brake caliper bearing is not locked to the shaft. it would take pretty much nothing for Cat to have a bearing made with a locking collar. There must be flex in the chassis that would cause premature bearing failure. Its like how the vipers and cat 1100s have those wobble bearings on the jackshaft to allow for movement.

Im sure Cat/yamaha know that most of these shafts will fail outside of the warranty period, so not really their problem. All sleds are built poorly for what they cost, the Japanese built sleds were no better, despite what people think.

Jon all of the Cat sleds have the driveshaft wear issue unless they luckily got a Unicorn Shaft that happened to be correct size and it rusted onto the shaft. I have seen one good one out of at least 20 I have done or seen. Many dont even know they have a issue since it almost looks machined that way. People have in there heads bearing failure on the driveshaft. If bearing is good they assume everything else is and ride on. Very few bearings fail on this design. But almost all the shafts do.

what is the story about the center skid shock ? warrantable ?

Yea stupid $hit like that. Really? Someone putting together shocks in their garage and smoking weed would have more common sense that to put a spring on a shock that was that close to rubbing uncompressed.

Yep it actually has been an issue since the F1100’s.

I still maintain it’s like everything else. These companies are making everything from washing machines to refrigerators, cheap and unreliable. Even if the fix costs pennies, they don’t do it because they want failure around warranty expiration.
Even worse is the fact that as soon as the machine warranty is up for that model year, they increase the replacement parts pricing.
I noticed this with identical parts that have different part numbers from one year to the next. The older part number is sometimes 3 times the cost of the new part.

Nice work you useless Bean counting fu€kers

Now way that bearing/shaft is failing as fast as these winders. 2012 is first year of procross and I assure you the 160 hp machines and LESS are not wearing like this. Not this fast. No way. NOT SAYING they are not wearing out shafts but not at 1500 miles.

Just to be clear there was no weed involved!

Why does it matter how fast it happens? It should never happen if designed and made properly. My 800 was toast bad at 3000mi. Viper at 3500mi had spun but was save able with dimpling. I believe Shagman found it first on his Viper which was still na at time and all off trail use. So very low miles. Probably is some correlation between miles and power but it really should not be something a guy even has to think about.

It doesn’t matter how long I agree. I’m just trying to point out that it’s not nearly as common in lesser powered sleds. It happens on ALL OF THEM in time but the wicked up ones are happening way faster.
