hifax issues

[SPRTNWD]

im about 400 miles on my stock hifax and they are non existant. im used to going much much longer of course on a lighter sled, but still ive got scratchers, i use the trails (very little) only to get to the good stuff and i feel my track tension is about right.

is this common, this is my first year with an apex mt, any ideas?

 

[SRXSRULE]

I dont know what to tell ya. I put on 1500 miles last year and left them for this year. I run ski mount scratchers and run them all the time on the trail. My suspension is all stock, limiter straps pulled up one hole.

One thing to keep inmind is they wear wuick at first and then slow down and almost stop wearing. Are they wore down to the line now? Eric

Does tightening limitor strap one hole make a dirrerence in wheeling, and holding front end down on climbs. I love the wheeling but on climbs it's a little scarey.

 

[pro116]

yes it will reduce the wheeling

replace the stock 5.125 wheels with 5.38 wheels

get them from richierich

Went on a long ride in munising in spots with horrible trails. Alot of people hyfax were smoked.. Mine were still brand new after 600 miles..

Also the track can sag a little in the middle when you adjust thack tension. Im going to set mine at 1.5 inches of sag in the middle and go from there when I put the 5.38 wheels on. need 6 of them for the MTN Apex

I loaned my sled out and when it returned it had burned through both hyfax, 140 miles, 64 miles of ice road towing a sled loaded with 110 gallons of gas(for the 2 strokers) and had also shed all the rubber on all the wheels except for the idlers? Now this year I have run it in marginal snow quite often with the presence of mind to jump off the trail quite often to cool everything down and with 600 miles of trails, they seem to be holding up well. So, I guess lessoned learned.....don't loan your crap to a kid that rides a clapped out MXZ! :ORC

thanks for the info,

i'ii look again but i think they are down maybe too far i hope i havent damaged anything. i'll check into replacing the wheels and adjusting the limiter strap. i might loosen the track alittle too ijust dont want to ratchet my drivers.

even with scratchers i am always diving off the trail or kicking snow on my hifax. ive put forth the effort but ive got a bad result

I just lost my hifax too. Only took 8 miles down a trail without much powder to burn them up. My front bogies that mount inside the slides with the front shock are also delaminated. Rubber is gone on the outside, local Yammie dealer is replacing those for free as it must have been an issue. That is also where the hifax is worn through (coincidence?). So ice scratchers are in order now. Any other options to keep the hifax cool on the Apex Mountain?

 

[Shivesy]

Do the Apex mountain sleds have any closed windows on the track?

Here's my new idlers:

I don't believe so, since they come with the extrovert drivers.

 

[Srxspec]

I burned off a set of hyfax on a Vector Mountain over the weekend in 190 miles. Low snow conditions will do that to you! The only place they were wore out was right ahead of the rear set of idler wheels on the outside of the rails (not the rear axle wheels). Going EZ Ryde this weekend so the hyfax being gone wasn't a big deal.

Is there a brand of scratchers people are having good luck with? My MPI scratchers only lasted 500 miles.

Anyone try the ski style scratchers?

 

[Snowsquatch]

I am debating on getting both, since they are about the cost of a set of hifax from the dealer. Might as well have as much protection as you can afford, no fun fixing your sled while everyone else is riding. I called Hartman and he told me that his ski mounted scratchers will work with 06-07 Apex Mountain.

Same here, had the front straps pulled up two holes, and my track adjustment was dead on Yamaha specs. The very first time I rode the sled, MPI rail scratchers down all day, 30-miles, and the Yamaha hyfax were toast. Got the clips so hot they melted indentations into my extrovert driver teeth and left hyfax chunks permanently melted into them. They look all thrashed now but they still work ok because it hasn't been ratcheting. After the first ride I put on a set of Hiperfax. The narrow ones because they didn't have the wide Yamaha style at the time, which actually turned out to be to be a good thing. The wide Yamaha hyfax don't let as much "snowdust" into the track windows to help lube and cool things off. My Hiperfax still look spankin new. At the rate they're wearing I'll get 3000-miles out of them easy. The two spots that wear the most are right in front of the idlers mounted to the front shock axel and right in front of the rear idlers where Yamaha "bent" the rails up in the rear.

HIPERFAX SLIDES

Regular snowmobile slides have a "melt" point of 300-325ºF. This is close to sled operating temperature. That's why slides sometimes stick and experience a short life. Hiperfax's PTFE slides begin to "melt" at a temperature above 702ºF. This is far higher than the actual sled use. Hiperfax slides have an extremely long life and will not melt away or wear out track clips.

 

[Snowsquatch]

So with the hiperfax you could melt you extroverts/drivers before you melt your hifax? Hammer, that doesn't sound too good, I just bought a set of MPI rail scratchers too.... Sounds like I shall be giving Hartman a call back and double my ice scratching efforts.
