i tried to put on my hyfax on my07 attak and noticed that they are a little wider on the part that slides on to the rails by about .040" and that caused them to not seat correctly on the rail at the top near the screw.
they went on very easy but the old ones were very difficult to remove anyone else have a similar problem?

Buy only Yamaha OEM!!!!!
The first time I removed my hyfax it took me 3 hours. I bought some aftermarket cheapos and there was no slit or cut in the front to compensate for the extreme curve it needs. The OEM's have a cut in the front. Make sure you douse the rails with silicone or something similar for the next time you need to remove them. It will make it much easier!!!!

If you learn how to do it a hifax change can be done in under 15 minutes.
1. Lay the sled on its side
2. remove the set screws at the front of the hi-fax
3. with a hammer and a long screw driver driven into the hi-fax beat the
hi-fax back about 1 inch.
4. Insert the screw driver through a track window and in under the
front lip of the hi-fax between it and the flat of the skid rail.
5. start the sled and gently engage the the clutch. The hi-fax will come
right out the track window and peel off the rail. Complete both
removals.
6. loosen the rear axle and take tension off the track.
7. spray the new hi-fax with windex and slide in rear track window and
onto rail ( large rubber mallet). drive in as far as possible. I use a 12"
piece of an old hi-fax through the track window to get it in the last 2 to
3 inches.
8. adjust track tension and tighten rear axle.
I used to go through 2 to 3 sets a weekend and could change them in the snow during rides.

Yamadog: Can picture this reverse techique. When the track turns the window in the track that the slider is being ejected out is also turning!
I have done it both from the front in forward and from the rear in reverse. When doing it in revers make sure your on the seat side of the sled cause I have been whacked with the hi-fax as it gets thrown forward. Also watch out for the screw driver it can become a deadly weapon.

I would love to see a video of this! I can picture it in my head, but seeing it in motion sure would help.
I have always owned Ski-Doo and recently purchased a new Apex GT. For the Doo, I would always remove the rear skid. Not necessarily because it was necessary, but I liked deicing it and doing a once over. Once in a while, it is nice to change the slides out quick.

so has anyone had the problem with the width and how they seat on the rail?
just hoping that mine will not fly off the first time i use them
one other ? the plastic guides on the front of the rail, should they have a little movement in them as far as back to front or should they be tight?
thanks for the help

Should be tight and it does spread the the part that goes over the T in the rail a bit and they always look like they are coming off on the front. thats why you have that set screw is there.

Charger did you purchase Yamaha hyfax? If they are aftermarket they could be made wrong. I just put the Yamaha graphite hyfax on my sled this weekend and they slid right on with no problems. However I had the skid out for maintenance so that made the job real easy.
I have yet to try the reverse gear removal procedure but I can visualize how it should work real slick. I am not so sure however about doing it from the front in forward gear since you do not have anything to stop the hyfax from sliding (rather than "peeling") like you do with the rail caps when you start "peeling" off from the rear in reverse gear.

i did use the yamaha hyfax, they just went on a little loose and started to spread apart at the front and i am worried about them staying on as these are known to be a problem. i am also worried about the front guides as they are a little loose too.
Just for fun, here's a previous thread regarding hyfax replacement: http://www.ty4stroke.com/viewtopic.php? ... highlight=

Charger, I wouldn't worry about them coming off, that is what the two philips screws are for.
My rail end caps were also loose. I have my rear suspension at the dealer getting the grease zerks welded and a delaminated wheel replaced under warranty so I will have him look at the end caps.

I just talked to the service manager at my local dealer where I dropped off my rear suspension on Saturday. He said that the loose rail end caps are normal and nothing to worry about.
Yamaha is covering the bad grease zerk welds and the delaminated wheel. Looks like I will have my rear suspension back by the end of the week.
Now if it would just start snowing!!!!!

I would definitely be worried about the loose rail caps. If you do a search, you'll find that they are the cause of missing track clips. You need to drill out the rivets and install bolts to hold them tight. The gap that is created between the caps and hyfax is what rips the clips off.
