Frame tubing split


Recommended Posts

Posted

I was under my Trooper today doing some work and I notices a split in the frame tube. This split was 7" long. When you look at the picture, imagine lying on your back with your head just in front of the right rear tire. Your feet are in front of the left rear tire. As you look up, you see the pivot point of the swing arm. The split tube runs from the right side of the picture which is the front of the Trooper to the left which is the rear. I expect a lot from my machine and have tested the fox suspension setup by running It off a steep slope at some speed that is about 3 1/2 feet high. My rear tires leave the ground at the top, fronts too and hit at the bottom. It's a pretty hard hit but the suspension takes it. Anyway, I don't drive it like that generally, only for suspension setup reasons. So maybe (for sure) I have abused mine more then the average owner and this is the result. However the split is right at the seam in the tubing. My seam just happened to be on the bottom side. It shouldn't have failed this way so the seam must have been defective. Generally you would expect a crack at a weld or joint where max stress gets consentrated. When your under your machine or otherwise, you might want to keep an eye open. With this crack being filled dirt, I almost missed it. To fix it, I welded it shut and then went back over the weld to make it extra wide and thick.

Hey Lenny,

When I rebuilt the water lines to the house I used galvanized pipe expecting it not to fail in the balance of my lifetime. WRONG, seam split of about 7 inches in my Home Depot Chinese pipe that was only 2 years old. So now two seam splits of Chinese tubing/pipe. I won't even get into my Chinese Trailer tires.

Thanks for the heads up as this is something those of us running over-sized tires & shock need to watch for.

      Looking for a output shaft for a Joyner trooper t2. Went to move the buggy after sitting all winter and it appears the out put shaft that drives the rear wheels broke off inside the transmission so looking for the shaft or a complete transmission if someone has one

      I have a 2020 800 sx with about 16 hours on it.  From day one I have heard a clunking noise from the front end going over bumps.  Has anyone else experienced this?  Also this past weekend while out riding I heard a noise that sounded like the dump bed bounced three or four different times, again has anyone experienced anything like that.  Thanks, gary

      Hey Guys, I have been chasing a stalling condition for about two weeks now. The bike will crank up and idle fine, then after about 20 seconds it will fall on its face and stall. It happens at both idle and while running at various rpms. You can turn the key off, turn it back on and it will fire right back up without trouble. I have verified spark on both cylinders with a spark tester. I have also added an inline fuel filter, and pulled the injectors to verify proper pulse on each. Things I have replaced - (relearn procedure performed after each component replaced): spark plugs, ECU, relay/fuse box, fuel pump, & throttle position sensor - all with no improvement of the condition. The only warning light I get when the condition occurs is the oil lamp. The bike only has 14 miles. I am at a loss and appreciate any help and suggestions! Thanks

      Hey everyone – my name is Adam and I’m doing some market research to better understand the ATV / UTV community. I'm especially interested in hearing about:
      What you use your vehicle for (work, play, etc.)
      What you love about it
      What frustrates you
      What the overall experience of riding has been like
      If you're open to hopping on a casual 30-minute Zoom or phone call sometime this week or next, I’ll send you a $100 gift card as a thank-you.
      No sales, no pitches—just listening and learning. I'd also just ask that you send over a photo of you and your side-by-side in action (nothing formal—trail pics or selfies are totally fine!).
      If you're down to chat, drop a comment or DM me and we’ll find a time that works. Would really appreciate the chance to learn from you 🙏
      Thanks!
      – Adam

      I want to ditch my Kubota RTV-XG850 and its moronic twitchy throttle design flaw, get rid of the problematic engine and the 40 mph purposely throttled speed.
      So far, I'm looking at the Honda Pioneer 1000 and the Polaris Ranger 1000, both of which have 1000-1500 lb payload bed capacity.
      What other makes and models should I be looking at?
       
      Thanks for the help!
