Seat Time-Belt feedback after alignment with Hurricane Tool

[fatchance]

Ran a 41/37 last year with Dalton B/B in front and B/O out back. Snapped a belt clean at about 700 miles. Going to a steeper helix this year if we ever get snow!

My problem is Im on tight trails, need snap corner to corner, and the steeper helix just become too sluggish down low as they shift too fast. on 270 map it can pull it though, but anything over 39/35 which is good on 270 or more, will not snap corner to corner for me. Sure its fine on bigger trails where speeds are much higher.

Cats run a compression spring, lots more backpressure/ steeper helix, and alot less gear(24/50) which end up with hotter belt temps, but the TEAM does not blow belts like Winders do.

140 miles. Was at a dead stop and punched it. In all fairness it had about 800 miles total. 140 since using the tool. New belt now, let’s see what happens.......sigh. 1mm float.

I'm running Dave's bundle of tunes as well Dan. No big trails near me, all real tight twisty stuff. I felt i had good corner to corner. No evidence of belt slippage as there was never any marking on the sheaves. It did run what i would call a bit warm, but never hot. Used Dave's tool, but too be honest my offset didn't change much at all with it. Haven't had it out yet due to no snow since the season opened up.

Hate to say i told ya so lol. Starting to rear its ugly head. Maybe knapp is on to something!

Team clutches run cool.

I’m speaking about the older cats with a torsional secondary. They were rollers since the mid 90’s. Thundercats, ZRT’s, ect.
Those torsional springs will work in a Winder clutch. More side pressure and less twist, these are the springs I use the most.

Throw a mo flow vent in the panel . Helps a lot.

Found this on YouTube. His clutches are filthy and his deflection is too loose but it's the same issue I am having

I will add.....

My blows seem to be snaps, which means tearing belts in two.

This IMO means incredible force to snap belt, where as alignment issues usually make heat and tear/pull cords then shred belts, not so much snap.

So, could this "too low" angle helix be the culprit all along? YAM using a low angle to help add backpressure, could this be just too low and causing far too much pressure which snaps belt? Also making the big tune HP snap them just that much easier/faster.

So will a steeper helix allow it to upshift faster, with less stress on belt(pulling it apart) but more spring to still stop slippage, is this different in some way then lower angle with less spring?

So question is:

What is difference between a Shallow helix and less spring VS a steep helix and more spring?

In theory they should both have good backpressure, but will steeper helix setup have less stress on pulling belts apart?

Dan I have a 45/37 helix I haven’t tried cause I am stock. I have a Hindle and cold air intake coming with my Power comander. Wonder if that helix would work with that setup with my stm ya 60s?

Yeah thats a very obvious reason for snapping that most of us know of. I have never whacked throttle when belt is loose like that though, But that will surely snap belts.

This season I sure hope is the season we all get this squared away, and have a clear consensus of what works.

Just not sure the alignment alone is the fix.

None of that helped my 13 turbo cat,it still blew belts every 400 miles no matter how many vents or even a fan on it,pitiful cat,pitiful POS.

Agreed. I'm brutal with my Apex and it just runs smooth as silk.

I think what people are missing, or forgetting, is that your weight profile dictates a lot of what your helix should be. The shift rate of your clutches should match. Your secondary should NOT dictate what your primary is doing.
I ran a 45-41 with stock tune and Heel clicker weights, aggressive shift profile weight. Stock springs. Stock rollers. The sled ran great, was a beast. BUT the soft material of the heelclicker weight flattened in 600 miles. No help from Randy at heelclicker. I wish these weights were harder as I have ran them for years in many different sleds with very good results. I have never had a weight grab the belt harder down low in any application.
I then ran stock tune, stock springs, 16mm roller with G Force weights, straight 45 helix. Sled went great, very smooth shift and gained MPG. Never blew belts at all. I also ran this set up with a 225 tune with more primary weight with good results.
If your primary weight and helix shift rates are matched I don't think you need big springs to control the shift.
Again, I could be wrong, I only stayed at a Holiday inn express last night!!
Keep the conversation going. We all learn from others experience.

I put on 250 today.
Spent the day adjusting suspension & trying to keep the skis on the ground.
Then a man named Glenn walked into the diner & asked if anyone had OCD.
It was FLEECER from TY.
Chased his 300 hp 'Winder though the Allagash on surprisingly good trails. We are actually running same clutch set-up except helix & he has more weight.

I should have some comparison's tomorrow to stock sled clutching temp wise.

Bud's stock 'Winder blew a belt today with 500 miles on it. He not happy! We need to fix this.
I'd say in 3 more weeks we should start to see some good answers.
