Hyfax Rail Fastener

[MDEVO]

New 24 9R rail. Other rail is good.
Polaris saying it’s acceptable and likely will not replace as it will
Not affect structural strength.
30k CAD for this quality is disturbing…..
Thoughts?

Why isn’t there a bolt on the opposite side? Post a couple more pics

This looks exactly how both my rails are on my 24 155 Boost. People just need to make sure these self tapping bolts are torqued correctly. This is the bolt that is backing out and people are losing their hyfax while riding. I checked mine and they were super tight. Perhaps people who are losing hyfax don't even have the bolts because someone missed them in production? Not sure if some sleds were more affected than others as being mine is a Boost and later in production. And as for how janky it looks, you are either blind or new to owning a Polaris because that is probably about 20 spots down the list when it comes to janky construction on a Polaris...

That's BS your dealer should be replacing that.

 

[JH@CM]

That's a factory defect.

Post pics y’all. Polaris reads these forums. Chadly more pics, less gum flappin

 

[shattuck]

No no no guys according to factory riders that’s pre ride or pre season inspection protocol
Not some dip **** at the factory didn’t get it tight and/or screwed the bolt in crooked. Probably the same guy that torqued the P-22 clutches last year.

I got news for you, if they do, it's only to make fun of the people who buy their sleds that they wish didn't.

OP - I've seen some discussion on FB about this. Seems to be normal and has been happening for some time.; like on the axys too and previous models to that. You let Polaris know; you have record of it. I wouldn't worry about it. Takes only seconds to look at it once in blue moon to see if it gets worse.

Actually check the length of the hyfax when checking the bolt torque. More than one sled is coming with hyfax that are too long.

Without the rail caps on the 24’s the hyfax needs to be trimmed properly. The hyfax is contacting the clips and in some cases pulling the clips off as well.

This is not my photo but you will see what I am referring to

what does a properly trimmed hyfax look like? Because my ‘24 looks just like your picture. Haven’t ridden it yet though.

i have read reports of the track clips hitting the hyfax and ripping them off.
does anybody know if the rail tips/caps from last years sled will bolt onto this years rail?
I know the new rail tip profile is different.

I read about 24’ hyfax problems on FB yesterday. Thought it was BS social media whiners. Checked my 24’ last night. The 24’s don’t have the rail caps like previous sleds. The front of the hyfaxx is cut at a pretty sharp angle and the as the track comes off the drivers the clips bang into the sharp edge of the hyfax. IMO, this constant “hammering” of the clips against the hyfaxx edge elongates the hole the hyfax retaining screw goes through and loosens the screw. I pulled my skid last night and cut the leading edge of the hyfax down to smooth the transition of the clips contacting the hyfax.

When we cut our rails in the past we wound trim the hyfax at an angle back to the rail. This hyfax extends past the rail and I have seen several like this.

I am not sure it is a 100% solution as the rail tips have less of a tip up now as well but it certainly isn’t helping.

The anti-stab wheels on the 24’s are also different. I want to measure to see if they are the same diameter as the 23’s.

Caleb has a good video showing how the hyfax should look when cut properly to avoid hitting the track clips. Basically want it about an 1/8th of an inch longer than the rail.

If this is normal, no wonder there are hyfax flying off…with only 3 threads of engagement in the rail.

Dear Polaris, can you please show us the stress analysis you performed to say the OP’s sled in the picture is good to use as is?

How many cases have you heard of flying off? Were are you seeing 3 threads of engagement in the rail?

 

[diamonddave]

Don't be a poossy Rusty! Ride it until she breaks.

I am poor and can’t afford Heli rides. We take too much risk as it is riding Polaris.

For those just looking at their rails foe the first time.

Polaris has used the same drill, tooling and fastener since about 03 to install hyfax to rail. The self tapper will always protrude out the sides of the rail beam a little on one side. Not sexy but there has been no change there. Guys judt trying to scapegoat the tip less design as not thr issue. Funny how suddenly after 20+ years thr screw method is suddenly bad at thr same time they went tipless....

Running a 2 wheel anti stab with no caps is not ideal but with good hyfax shaping is doable on smaller pitch tracks. 3.5p tracks have such giant windows its really sketchy at best. Coupled with the steep chop sawed hyfax front edge there is a constant hammering that will either rattle the screw oit. Snap it, or pull the hyfax over the head.
