Hi fax wear

[Snowking]

I put new hi fax on at the start of the year and with 500 miles on them they are about shot. The back 5 inches are really wore compared to the rest. The track has about an inch and a quarter sag in it when on the stand. Could it be to tight still ? Could the rear wheels be shot? 300 of the mile where in the UP last weekend and the snow around town has been great. It's on a 99 700 with a 136. Thanks. Chad

I would lean towards a tight track and possibly inexpensive hifax from fleet farm...

Plus + 1. And you may want to look into adding another set of extra wheels on the rail where it is wearing the most to help with the pressure.

So how loose would you run the track ? The wear acures by the Back wheels. I was wondering about the wheels if they wear out. The sled had 4200 miles on it.

Assuming this is a short track (121") 1/2-3/4" of sag from the middle of the track. The only concern you should have is the bearings warring out and you'll kind of know that when it happens. If you can suspend the track via bumper and loosen up the two bolts and nuts at the far back you can free up the boogie wheels and look/listen for shot bearings too.

Good luck.

Sorry just noticed its a 700 136" track for sure 3/4-maybe 1 1/2" of sag. Don't be afraid to go to the 1 1/2" but if you here allot of slapping or clunking it might be to loose but not likely. When taking off HiFax make sure to take belt off and free up track to spin freely so you can rotate track to line up the holes in track to your Hifax. A long punch and WD40 works great pushing them out. If interested theres a ton of Youtube videos on how to remove HiFax just don't do the "reverse" version for safety reasons....

Oh one more thing don't take both out at the same time just do one at a time and make sure you're cutting with the groove facing up. You'll have to measure and cut the new Hifax to match the old one and don't assume they are both the same length and you'll want to cut the end short enough to not restrict the track when it curls up and around the boogie wheels another words cut at a small angle or degree downwards for the angle of track.

Make sure that the sled is warmed up for some period, cold tracks and hifax are tougher to remove when cold.

Lot of good info, from MR there.

What size lugs are you running and have you replaced the track with something else then what came on it? Are all your clips still there and good? How loose are you running your rear springs and shocks? A lot of rear sag can throw some of the weight on to the back. Some guys do this because it's cool to lift the skis off the ground when they hit the gas!
