The Flying Nun

[Summitstef]

A week ago while rebuilding the sled's ticker, I looked down and noticed that one ski was further ahead than the other (about 1.5").I know exactly what this means. A bent NUN. Sooo how big of a pain in the arse is it to rectify this problem. I don't want to start tearing down the sled due to the fact that winter is sort of here and I REALLY don't have the spare time to do it. Will it be okay to ride it as is. I looked under the entire undercariage and found no cracks etc. Any feed back/ instructions/ comments would be appreciated. Thanks

Im in the exact same boat. Im going to give it the 2x4 treatment wednesday.

Don't be afraid to tackle the job. I did my first one a couple of years ago. It was pretty straight forward.
If you got a warm place to work and maybe a buddy to help, you can do it in a day.

For only 1 1/2" I think I would tie it to a telephone pole and put it in reverse and bump it a few times and ride it until next season or trade it next season.

Try to find a buddy of a buddy (or somethin like that) who works at an autobody shop. I paint cars for a living and have worked with bodymen who have pulled sleds after wrecks. i think a 10,000 pound hydrulic ram for car frames would straight'n it

One problem. I don't know which side is out. I bought the sled used.The shocks are not touching the A- Arms, and I don't want to sell it. The top end has just been re done with 148 pounds PTO & Mag along with a inner rear wheel kit, 10" riser, 6.9 pilots, Dynoport stinger, '07 summit XRS seat and the 07 tail light kit. With the third kid on the way, this is as good as I'm gonna get!

I am in the middle of replacing the flying nun as we speak. Not really a big deal so far, but I have not started assembly yet... waiting for the part. It took myself and one other person 1.5 hrs to get it to the point that we are ready for the part to put back on. The only thing I can see that may be a problem is that I will not have enough of the correct rivets when I go to put it back together.

We rode it a whole season with the nun being split in 2. (didnt know it was split until I went to do a top end.) Didn't seem to hurt it much but on one side there was a lot more flex then the other!!

If you are looking to see where it is bent, take the can off and check there. if that side is normal then its the otherside so take off the primary and take a peek behind it. thats where mine is bent. If you bend it back you will need to fabricate a brace. Mine is back about the same as yours but am leaving it till i really do it in or next summer.

I have replaced quite a few of them. First though, most people would never be able to tell that it is bent by riding it. If it is not bent bad enough to affect steering you may want to just run it. If you do decide to break it down and replace it, make sure you buy a pan weld as well. Nearly every one that I have replaced needed a new pan weld(the aluminum plate between the nunn and the frame). Overall the job usually takes me 6-8 hours. Not real challenging, but a little time consuming. I would just recommend having the parts on hand that you may need. It is usually my luck that if I get into it and need a part, the part is usually on back-order.

I am doing my third one for friends(I ride polaris)...go to your dealer..they make a brace that goes on the wall the can sits on..you should pull the t-case to install but this brace really helps reinforce it....(sorry I dont have the part # but the brace is for the race sled..its an aluminum extrusion that is precut and drilled to fit)if it bent the nun bad you may also have to replace the flat plate that goes across side to side right where the nun bolts up...

Great recommendation. Here is the part #518324096 it is a RH tunnel stiffner. It bolts on rather than riveting on like the stock part.

A buddy of mine hit a railroad rail end with the right ski of his REV, it tweaked the nun, you could hardly see it, except for the ski and the a-arms were not the same positioning. The side that is tweaked would be the ski that is set back more.

He took a chain, and a come along, went between 2 trees that were about 15 feet apart, attached the come along to the lower a-arm, then to the front tree, then attached the chain on the upper arm to the rear tree,,,, He cranked it a bit, and it pulled back fine

I would take your pipe out, and your can and look inside. Check for stress cracks, they usually crack on the brace above behind the upper shock tower. Make sure your bulkhead sides are not tweaked, if so, get some 1/2" x 1/2" square aluminum tubing and bolt it across, from front to back.

air riveters rule!

Take a look up at the steering assy where all the parts meet (steering stem). Most likely it is cracked there too....
