Yet another 08 Nytro front end question...

[thesnowgod]

I've been reading on and off for nearly a year now about solving my darting problems. I think I'm understanding some things but since I've got the skis off mine, some things are just now starting to light the lightbulb in my head so please bear with me!


When I jacked the front end up, I noticed a lot of play in the front skis. The ball joints and things seem pretty decent (not perfect but acceptable for me). By FAR the largest area of play was where I'm pointing in the picture.



Is this the "bushing" that everyone seems to speak of when they mention theirs is worn out?? Before I put everything back together, I've GOT to try and get rid of the play in this area. If I grab the ski tips, I can move them all over the place so I can't imagine an alignment will be all the effective with them this loose.

What is the recommended procedure for fixing this? This machine darts all over worse than ANY machine I've ever ridden. On groomed trails, I prefer my old 97 Formula Z to this. It's really a white knuckle ride and not something I'm simply exaggerating about. No one else I ride with will even TRY this sled more than once so I know it's not just me.

One more question: I "thought" I recalled reading where someone took the spacers that are on both sides of this bushing and placed them both on the outside of the spindle to increase the center to center ski width. Is this advisable? It seems like it might put a little extra stress on one side of the ski to spindle bolt.

Right now the skis (USI Triple Threat X2) are off because I'm adding Stud Boy dual runners with 6" of carbide to them hoping this will help too.

Thanks everyone.

Most people complain about the a-arm bushings. But you are right these get very sloppy too. I don't think you can even get new bushings for the lower sleeve.

The bushings everyone replaces are the ones in the Arms where the mounting bolts go through. they are thin plastic ones from the factory. that is obviously just your ski bushing but is possible its worn. i know mine were pretty bad on my 08. you can just buy new ones or have a machine shop make you a set if you know anyone. i would make some by checking the diameter of the spindle and make some close to that.

Is it best to buy them from a dealer? *shudders* The rest of the front end is nice and solid compared to these. Where that piece goes through the spindle, I can move it around quite a bit.
Oh, and thanks for the fast replies guys.

Where about in upstate NY are ya?

 

[thesnowgod]

Camden. How about you?

Oh cool, im from the Remsen area, not too far from ya. let me know what you decide to do. i work at a family owned machine shop and can basically make anything. so if you need anything made for that spindle i would be glad to try and help ya out. gotta figure out of the ski bushing is shot or if it is the bushing inside the spindle thats worn.

Stainless spacers and axle. I also made oillite bushings to replace those in the spindle.

The OEM bushings in the spindle bore are locked down with some serious gorilla snot. You'll want a shouldered pin and a bigger arbor press to push them out, if you go that way.

Are you selling those Arteeex?

 

[thesnowgod]

How would I get a set of bushings and pins like those that you pictured? I don't have a press. Is there a way to use a bolt and nut to get those inner bushings out?

X2, id be interested. save me from making my own lol.

I got a press at the shop that we could use

 

[thesnowgod]

That'd be awesome of ya. I keep looking at them and trying to figure out how the heck I'd get them out.

I'm REALLY hoping this helps with this darting problem. She's all over the trail like a nervous crack whore right now.

 

[2008FxNytro]

And we all know how those nervous crack whores are....i mean ummm. lol. Yea thats no problem. if cant get the bushing from arteeex we could prob make some at the shop too.

I can make the spacers (but I'm running low on time right now) and I might suggest that you use the OEM pin as its hardened and won't wear as quickly - strength of the stainless material is not an issue. I'm okay with the stainless pin on my sleds but then I live on the edge and my standards are lower.

You might get the OEM bushings out of the spindle with a bolt and nut but they have a thin wall so a shouldered piece is still a good idea. If you want to get all Neanderthal on it, you can just beat them out with a hammer and screwdriver too. My experience was that it took a lot to push them out. That may not be the case for all. Check the clearance with a fresh pin (it's 16mm as I recall). If it's close leave the bushings alone. Once you start pushing or pounding them out you will be committed to replacing them.
