excesive Hyfax wear Cont...

[mateo]

After reading ttabs modshop a few times WRT the timbersled install as well as other posts, I have a few Q's
[Running 162 powerclaw, Iceage and timbersled.]

- How much does weight affect wear? (I.e tandem riding)
- Snow conditions.
This one seems obvious that on a packed trail, without scratchers you dont have lube and you melt your sliders. BUT
I replaced the sliders on my Nytro (have scratchers) while my buddy just walked off the showroom with a new XP without scratchers.
He's ripping up groomed trails with packed snow with no issues w/o scratchers while I'm melting mine something fierce.
I've burned through a set in less than 200km (they are down to the wear mark now.)

- Limiter straps. What kind of affect does this have. I blew both limiters one day on a tail landing, and did field repair.
They are definitly not exactly the same length. (+- a 1/4 " or so)
ttabs talks about tightening them up a bit. and loosening the track tenstion. I thought that was only on the stock skid tho. How does limmiter strap setup affect it?


Thanks,

problem is yamaha has smaller idler wheels and their mounted higher up from the track then other sleds. buy excell wheels. their bigger and will hold the track further away from the slides. problem solved.

In that last picture, are you putting any pressure on the track? I have about 2" of slack from the middle of the skid. I also fully clipped my track this year in hopes that it will reduce some hyfax wear.

That pic is taken sitting on the deck. The track is loose. Maybe too loose?

Mateo:

I think its the excessive water/ice from Yamaha's rear pointing exhaust that is really the root of all our hyfax wear problems. Sounds counter intuitive, with all the water sloshing around, but once ice forms around your suspension, my guess is the ability of the snow to get to the slides is impared. Undertunnels, by adding more heat/water just make the situation worse.

It's rather strange that Yami's seem to suffer the most when it comes to slider wear.....and its on all their sleds...

That said, I see you are wheelless aside from the antistabs, but where are you wearing? If its at the radius, you can install a couple of bearings on the Timbersled front cross shaft that suports the lower end of the fox float shock. I saw someone do this on a thread somewhere on TY. BDX offers a similar wheel kit for the lower front shock shaft on the M sleds, which I use and it definitely helps.... here's the link for the idea:

Unfortunately it won't fit the TS skid because it has a bigger shaft diameter, but you get the idea.

If its where you sit (that's where mine normally wears) try a couple of those Yami marginal wheel kits. With IceAge rails, the Yami ones will work best as they only have one bolt thru the center of the I beam. You'll have to modify them a bit, as the TS/Iceage rail profile is different than Yami, but its an hour's work with a hacksaw or router to get it to fit. Worst case a small machine shop job.

The reaon I like the marginal kits IMO is you can put them exactly where the wear is the worst, and they are light weight.

Hope this helps....

For sure not the solution for a proper mountain sled. I and many others are running skids with no idler wheels at all and we have still got no hyfax wear problems. A mountain sled used the way it is supposed to be used (in powder) does not normally have hyfax wear problems, no matter if you have got a skid full of idler wheels or no idler wheels at all. If you do need to transport it down a hard packed trail, you use ice scratchers and you will still have no hyfax wear problems.

In my opinion, a mountain sled with hyfax wear problems is because of one of the following reasons:
- Transport on hard packed trails without ice scratchers.
- Not transporting but racing down hard packed trails.
- Bent suspension components causing uneven wear.

I have got no experience of two up riding, but I can imagine this puts extra load on the hyfax...?

Did not notice ice scratchers on your rails. You may want to get a set, helps tons.

Get some scrtchers!!!! Traditional wire style, or SlideKicks. The traditional style work best but may not last long unless you remember they are down and put them up off trail or reversing. I like many people run NO wheels..

I don't know if i am the only one that noticed it or not but it looks like your drivers are not spaced properly and could be causing some of the issues as well, in your 2nd and 3rd pics its clearly visible that they are driving off to one side and the left side is wearing excessively due to this.

 

[Mtnviper]

Looks like your getting exessive heat due to lack of lubrication. Notice how it looks like the track clips are melting into your drivers. The added heat is also hard on tracks.
As the guys mentioned in the previous posts, ice scratchers are the fix. Helps cool your engine too

Thanks for the replies.
I did have scratchers - the wire ones, First the left side broke off, then 2 days later the right. So I have sidekicks on order.
The wear is along the full length of the sliders.

Looks like there is no consensus on wheels vs no wheels, but I would imagine that with no wheels, one needs to be very religious about scratchers down on most trails, and can be a bit sloppy when you have wheels.
I'll install the new scratchers and new sliders and see how long these ones last - hopefully more than 5 rides

My first set of sliders last about 500 kms.I was less than impressed, so after some reading i decided to loosen my track. I run my track as loose as you can put itwithout ratcheting. I put on aabout 1100kms and dont have any sign of wear on these sliders.

 

[mateo]

I have about 1 3/4" of track sag. Less than 3 fingers.
From what I've read/heard it seems pretty standard.

CLIP YOUR TRACK! start with the simple things, A full clipped track is a must for any machine that runs in low snow, Like other people have said get an aniti-stab kit, it wont solve the problem but it should help out with slider wear close to the rail clips.
