Measuring offset

[fatchance]

Ok, i guess the simple but obvious response is if it only floats before engagement what would it matter?

We are talking about float while engaged so the belt can find alignment on its own. The problem lies when guys blindly allow the secondary to float when alignment and offset is so far out to lunch it doesn't help with alignment along with the fact that allot of times the secondary won't come back in unless completely on decel. That combined with a primary that "hangs up" creates a poor situation for belt life. If you know your stuff and have good backshift with proper alignment float can absolutely work for you.

Did you search remove float? Did you understand the concept and what it would take to remove float? Clutch theory can be hard to understand at first, but usually there's one thing that you grasp and it opens the door to understanding how it all works.

So when the belt is up as far as it can go on the secondary and the bolt with the washer is pushing against the helix, does the secondary slide back and forth on the jackshaft or not? Mine does not and any of the winders with those washers that you are talking about for deflection adjustment wont either. I do understand the "float that you and Mike are talking about but that kind of float isnt the same as what RB200 was asking about.

He titled the thread "measuring offset". Unless you lock the clutch from floating as I described then the offset has the potential to change whenever the machine is in motion.

Ok, we are getting somewhere now, when you said " if it only floats before engagement what would it matter", it matters because that was the question that I was answering from RB200. I dont think anybody read his question as everybody was talking about actual clutch float and not what the question was about. Oh well, was lots of good info regardless, thanks fatchance

17 winder.
57.5 mm
This is how I check my offset after I set it with the Hurricane bar.

Nice old caliper that has a gauge on the back side of it, awesome!!

I measured the displacement with and without a belt. 58 mm. I removed 2 mm from the rear of the secondary clutch.
Arctic cat Red White spring. XS 825 belt. In deep snow, the clutches are hot.
No tune. Stock sled.
What can be done to reduce the temperature of the clutch?

Ya I got my offset at 58.5mm and my secondary still gets hot as well. Not sure if thats just the way they are or if someone has had success in keeping them cool. Running the XS825 also

Clutches need to be mocked up to find the proper offset. Every sled will vary.

Clutches don't run "cool" when under power and in deep snow. Maybe going down the trail cruising with a lot of air going thru under the hood they do. But expecting "cool clutches", some one let me know your calibration when you get it under power in deep snow.
