I unbolted the rollcage on a new UTV and when I pulled the bolts out of the front attachments the cage pull a apart. The cage had a lot of preload in it. I trying to figure out the best way to remove this preload. The only thing I can think of is to bolt every back together and go up about 1.5 to 2 foot way from this and heating the cage red hot and let it cool. I know this a less that idea way to do it. I am in a wheelchair so building a new cage is something more than what I can handle .

I have a MIG and oxy acetyl torch and metal cutting saws.

I do not like the idea of stressing the main frame with this misalignment of the rollcage

Do I spy a new YXZ?

I wouldn't touch it. There isn't nearly as much structure on the roll bar as there is in the main frame. There is a pretty good triangle just below that mount on the chassis.

Looks like a YXZ, I would loosen all bolts.
Then tighten bolts after main roll bar is tighten.
Rose red will not help in a roll over.

Definitely the Yami.

Why unbolt it in the first place?

Congrats!

If it really bothers you, just add a spacer to each side.

Just like me, I have to take everything apart just to see too! LOL

I'd just use a clamp or ratchet strap to align holes and bolt it back. Wouldn't heat it. Now if your thinking aftermarket cage now that I'm sure we can help with.

Wrap duck tape around the tubes about a good ft up so ya dont mess the paint up on the tubes that are tweeked a bit and find a pipe to slide over and tweek it back

I figured Yamaha would have better QA than that. interesting. I'd probably just build a new cage if it's in your budget.

Polaris' QA is similar to what the pix show too.

I'd leave the preload and just use better quality hardware until you can rebuild a new cage.
If you use too much heat it may make the part you heated brittle.

Use ratchet tie downs wrapped around each pillar to compress it back to bolt alignment. Put a Thin shim or thin flat washer between one side of the mounting point and reassemble to torque specs.

Then add a cross bar above the dash connecting the pillars on each side. Welded or Clamped.
The cross bar will keep the pillars closer together.
Remove the thin washers on the one side and then retorque all the mounting hardware.

We pulled the cage off of an rzr to replace it with a race cage and it sprung 6 inches in one corner. I think all of the manufacturers are the same. The roll cage isnt very strong by itself.

Its a Yamaha . I am converting it to hand controls. I am working of trying to make a bar for the 5 point harness for the shoulders. The bar in the Yamaha roll cage is about 8 inches above my shoulders. I needed to get the plastic cargo bed panel out of the Yamaha to find a location for a shoulder belt bar to be around 3 inches below my shoulder. The only way I could the plastic cargo panel out of the Yamaha was to remove the roll cage.

I am posting a step by step tear down of the Yamaha at the link below

If you want to see a Yamaha with no plastic there are many pictures. I trying to come up with a place to locate a shoulder belt bar. If have any comment about my bar location feel free to make comments in this post on minibuggy.net

I had a feeling it was something to do with hand controls.

Keep us posted Stress, and again, congrats on your new ride.

FYI - the Yamaha and the AC UTVs are not tied at all. They each design and manufacture their own machines.
