Team Primary on Winder secondary mocked up

[stone88]

I would be careful with that dayco xtx belt I tried one 2 weeks ago it lasted 9 miles and a big chunk came out, not sure if its a fluke but another belt in the junk pile.

Yes, I was a little reluctant to buy the XTX, they were great many years ago when they first came out for quite some time, and they went through a period where you couldn’t keep them together. I was hoping they have that solved by now. I had issues with that chunking for a period of time with my ski doos.

The guys on the cat site seem to like them again and are actually claiming they hold up extremely well, so we will see. If the XTX doesn’t work out, I will have to look at the Carlisle XS or the cat 112 belts.

Hope someone hear can shed some light.
Installing my dalton weights and Yamaha spec it says to torque the cap screw that secures the weight to 4.3lb-pds and set screws to 2.5 lb-pds and 17 ft-lbs for the primary clutch cover.
Question for everyone: If these 3 areas are over torqued, could it cause addition tension on parts that when running at higher hp, it is causing the sheaves to break where the weights are anchored.??

Sheaves are breaking like that when the weight swings past the roller.

Mike, I think my NEW WARRANTY Ultimax is a tad diff/tougher....The box and address came from Timken, So Carlisle is no longer in their name. Not sure if there is a diff, but so far so good.

I have seen far more positive Ultimax reviews around and Ron seems to like them.

Put another 300kms on mine today, for a total of 900kms so far.

Time will tell.

Dan,
I have a Dayco XTX to start with, not a Carlisle Ultimax XS.

Hope you found some snow to test!

I believe 3 years ago Dayco had a bad batch of xtx belts. If you bent them backwards they would split like cardboard so easy to check. The free replacements are fine. Probably some old stuff out there so check by bending backwards before you buy.

Awesome Mike!!
We have 2 2017 Cats and now my 19 141 Winder, all running 290-300 hp tunes, all studded, and all of us have lots of tuning years.
On our 2017 Cats we completely punished the new version 112 Cat, chopping throttle, WOT 125mph runs all the belt blowing ways...and the 112 will take a beating.
Dayco if I can remember grenaded on us, and no matter what belt we tried on our Cats if you looked in our side panels you will see us running the 112 Cat belt.
This was all done with stock clutches, mostly Dalton components, studded aggresively. (However all clearnced and indexed, and my 17 has Ronnies torsional conversion, but the others are running fully stock drivens with just a spring change.
One thing I can tell you about the Cat 998s is mine did not like tall gearing at 21/38...possibly if you drove rock hard groomed everyday its ok, but I had belt issues with the tall ratio in my 2017 Cat.

Now on my new 19 141 Winder this thing is a myth....We didnt have success using Daves bar, I need to revisit that...however when we used parralel bar method from SJ, we measured right close to 60mm, and mine does not have any shims behind the driven from factory.
So....I wanted to go sledding...took it out with a combination of FPP and homemade clutch recipe for 290 tune....I tortutred this thing trying to blow a belt off it, held it wide open at 125 plus, busted trail for 20 miles, and off hard on the throttle for 350 miles....no rubber transfer on primary, 8JP looks new....One thing I have found is that this sled likes LOTS of driven side pressure, it took two of us to preload my driven...and the sled is hauling the mail.
Stock gearing, 1.6 Cobra, heavy rollers in the driven, Dalton helix etc. I have a brand new 825 to try as well....and a Pro4 Primary.

I have a Team Primary on my bench loaded with my 17 set up using Dalton products, however I am waiting for you to test your set up.

Awesome thread Mike and thanks for all you do.

I didnt think a jp would take that much rear spring without crushing it but sounds like you have a great recipe.
