Here's a track alignment/tension tool been using for a while.

Interesting.  What is your assessment?

I like it.  Use to hang a weight off the track to adjust them.  Start the sled to spin the track and make a final adjustment. 

With this I've haven't had to adjust the track after setting it with the tool.  I normally run my tracks a little loose and it's easy to gauge how tight or loose with the index lines on the tool.

I think I'll give one a try.  I run loose as well, and sometimes a bit to loose.  

Is it just too simplistic  to do it by eye????  that's what I've seen  my local  Arctic Cat do for ever....

For me I run my track loose almost to the point of ratcheting.  I've had to adjust my track on rides on occasion.  Using this tool with a more precise way of measuring I have not had to adjust my track during a ride.  I also work on sled on the side and don't have the luxury to test ride them so it works out well for that.  If you look at an Arctic Cat service manual Arctic Cat also has a tool to check track tension.

Same here.  Been doing it by feel for years but sometimes you miss.  Plus I maintain 4 machines so this could be a nice time saver.

most manus give you a force and location to pull, and a distance it should be from the rail.  New guys get a fish scale, and tape measure.

After a couple hundred a year, you can eyeball it lol

I always run it on the stand for left right alignment, and make sure the center rear idlers are running centered in the rows of internal lugs.

It's internet lore that running a super loose track is fast.

It's a balance.

A track that is to tight will loose top end.  A track that is to loose to where you loose top end will also ratchet on acceleration and braking.  Find the point where the track ratchets and tighten it up alittle from there.

I might try this too. For some reason it's hard to get it running right in the middle and it sounds like this will make it easy.

Even if it's not ratcheting, if it's close to ratcheting and the track nubs are moving half way up the driver nubs, that's a lot of friction which is wasted energy.  If the track is flopping from excess play, that's wasted energy also.

Different ways of looking at it.  It's also shifting to a higher gear technically.

I'll go with what has worked for me over the years and with testing.

They also balloon causing a ton of drag if too loose. Erik woog has a good presentation about track tension on you tube. I do have the woody’s tool but have never used it

Explain what you mean about shifting to a higher gear.

Engaging the drives at lower smaller dia compared to mid or higher larger dia.  Same as the primary clutch and belt on a smaller scale.

In testing with a tight track always had a slower top speed.  Loosen the track until you start seeing the speed fall off which was normally when you had ratcheting under braking and sometimes during your hole shot. You'll normally get ratcheting during braking before your hole shot.  Tighten the track at that point 1/2 to a full turn when you feel the track ratcheting.

No idea what you're talking about with the gearing thing. But a tight or loose track doesn't change that at all.

And like I said earlier I don't subscribe to the loose track thing.

Thinking you guys need to buy a draggy and do some testing.. Tight track is faster in every way. Ballooning the track is the biggest speed robber up on top end.

Sold my timers and radar gun years ago.  There's a sweet spot between the track ballooning and being to tight.  This is just an easy way to be able to measure it to stay in the sweet spot.

No I agree you CAN go to tight. BUT. Just go watch the outlaw sleds and or big power sleds. The track is tight as a banjo string when the sled is lifted of the ground. Like no sag what's so ever.  Many think loose and or just tight enough that it does not ratchet is fast.. Its just not and a draggy and testing will prove it. Trail riding probably not a major issue. It is a cool tool to save time.. And trail riding I run mine with a little more sag.. But running down the track its banjo string

For ice racing we run the tracks as tight as you think you can possibly run them, then give the adjusters a few more cranks for good luck.

  for sure..  When the slides start to dust/wear slightly you gotter just right

Just run the Vespel ones and high clip every 3rd clip.

I used to love the "super slippery" from wahl brothers.. They have not carried them for a few years now but I did like those and felt they cut friction alot.. Maybe drill them out a little. Good idea on the vespel

Use to put the slides on a table saw and cut a slot down the center.  Before you line up for radar or speed runs run the sled in snow to pack center slot with snow.  During the run when the slides heated up this would melt the snow and lube the slides.  This is old school.

You guys have better tech/products you can run now.  Neat to watch and read about.
