Broke my sled.......again!

[XP123]

It looks like we all need to have a shop where we can manufacture parts for our sleds. Maybe now that I'm retired I can build a fabricating shop out back so I can develop and fix all the things Cat has yet to address. I'll bet it will be a full time job and I may have to hire a few employees.

It should be a sticky at the top of the Sidewinder forum that people need to switch out these shafts.

I know of at least 6 people with turbo vipers and 1100 cats that have broken this bar.

I have had limited riding this year because of family issues.
One of the few times i was able to ride my trip was cut short by this exact same issue. (But im on a viper.)
The next time i went to ride, it was again cut short by a blown out stock muffler. (2nd muffler to blow out on me)

I bought the tunnel reinforcment plates. I will powdercoat them and install them over the summer.
I also plan to make a new cross shaft out of a higher strength steel. Possibly chrome-alloy. Im still looking into this.
I will drill and tap it about an inch longer than the bushings and use grade 9 bolts to bolt it through the tunnel.

I will also be removing my front arm and reinforcing the living #*$&@ out of it. Mine snapped clean in half on me. I dont care if it weighs 46 lbs when im done. As long as it wont break again.
Im 51 years old, not 18 The goal here is to be able to ride this thing like a 51 year old man on a RTX and not break peices every 1000 or so miles.

Honestly i thought the apex mono skid was weak. That thing is built like a tank compared to this articcrap.

I had the RR pieces in my Cart on an online store and I thought it got pretty expensive, then clicked the shipping and I said no way are these parts worth that.

That said, it is going to be a common problem just like the brake, brake caliper, bearing and shaft. At some point it will all need to be modified and fixed. I had planed to take it all apart next fall and deal with this less than adequate engineering mess, fix and modify it on my sled.

I think I may just epoxy a piece of chromoly tubing over the top of the stock shaft. Quite obvious the stock shaft only takes so many hits before it breaks outta there.

I have a five year warranty and if it broke on me I'd want it warrantied. Cats engineering at its finest here, same with the brake caliper, bearing and shaft issue. Never have this problem on a Doo 1200! Biggest concern there was the brake rattle that had to be dealt with every couple thousand miles, and to think the guys thought that was bad.

This ProCross chassis is still a PIECE OF CRAP CAT, but at least its now its finally a good riding and handling POS Cat, something that couldn't be said for the 2012!

What’s the problem with the brake, brake caliper, bearing, and shaft? Are you talking about the drive shaft spinning in the bearing, or is there more?

Yes, that and the brake hanging up which mine is now doing along with wearing the pads out.

Doo has this figured out but not Cat apparently.

Put the aftermarket light weight rotor on .It's nice ,runs much cooler also .

I have the race brake on the LE already Ken.

On another note , I'm just in from putting a different tuneup in the clutches, going to run the longer Apex belt in a Carlisle XS 805 and see how that does as I have a few on the shelf from the Apex days. Freak April snowstorm here and hoping to get out tomorrow if it keeps snowing.

Had to change another set of rollers in the drive clutch as another set of roller bushings all broke and worn, the dang things have less than 500 miles on them! I know the XS belts runs lots less RPM therefore needs less arm weight.

This thing eats drive clutch rollers and belts for breakfast, lunch and dinner on the big tunes!

Mike,I've been using the gates with no issues ,The only belt i blew was the xs belt .

Before you put those old belts on bend them backwards and look for cracks. I threw all my old belts away. They all had cracks.

Change your rollers to the 15.6mm ones and they shouldn't push out the bushings anymore. 2019s will have bigger rollers.

No need to make a new cross shaft. Buy the RR cat parts, or the Yamaha LE viper cross shaft and bottom shock mount as well. I have broke every skid on every sled Ive ever had pretty much. Put the RR parts in my RTX skid, 6200kms of beating on it and nothing broken yet. I am actually super impressed with the durability of this skid.

Done, these two XS 805's I have here are in good shape. We only got about 8" of snow however, won't be getting out today.

The bushings are breaking and wearing out, has nothing to do with the rollers outer Dia.

The guys that are expecting some kind of magic from next years clutching are in for a big letdown. Roller size will do nothing to prevent bushing cracking and wear, and a slight helix change will do nothing to prevent belt breakage, It will however give people hope they have found a belt blowing cure and keep sales from slumping off.

Does anyone make any kind of brace for this chassis that would prevent the possible movement out of parallel under load?

Soupy was going to have Price put his sled on his chassis dyno to check what was happening under load but when he showed up Jason didn't have the right connections I guess.

I disagree. This primary clutch is the same basic design as previous Yamaha primaries, except the spider and castings are thicker. Myself and my group of riding buddies have been running high hp turbo apex, nytro and vipers for many years. Never have any of us had a problem with pushing out the bushing on primary rollers. Only difference is 15.5mm rollers vs the winders 14.5mm.

If the roller itself is getting damaged, it is because the bushings are getting pushed out of the roller, then the roller doesn't spin anymore, and the weight sliding on the roller is what is causing the actual roller to get damaged. My sidewinder had over 6000kms running 80+gram stm weights on the original 14.5mm rollers. Every 500kms or so one of the rollers would push the bushing out, and I would take it out and reinstall the bushings and be good for another 500-1000kms. I wanted higher engagement, so I decided to switch to some 15.5 mm rollers I had lying around, and after 500kms or so the bushings are still where they are supposed to be in the roller. I ran out of time this season for a longer test, but I am sure this has solved the problem.

To the guys that are snapping belts with cool clutches, its because the secondary and primary do not work well together in stock form. The belt doesn't stay tensioned properly in the clutches, and the belt going slack in the secondary and then grabbing all at once and snapping it in 2, or damaging the belt so it snaps shortly after.

The other problem with blowing belts is the offset being incorrect, measure it with straight edge or hurricanes tool. This is not a problem that is new to the sidewinder. We haven't seen much of this problem before because a Viper doesn't have enough power to fully shift the clutches and destroy a belt like the winder does. On my brothers 400hp viper, we also had to machine the back of the secondary clutch to achieve proper alignment when fully shifted out.

My buddy is just over 5,000 miles on the same clutch parts except for STM weights, springs and helix change. Original rollers etc... Been running the XTX belts or the 8JP same belt life for each around 1,000 miles to a belt.
