Clutch SPRING chart - Doh!!!

 

[OutCast]

Are you looking for a chart with all the springs listed with their rates? If so here it is!

VERY Helpfull - thanks!

Thanks for the chart with all the start/finish forces!!! Just to be clear, I'm under the impression that you use a distance of 1.34" (start force at 2.5" minus finish force at 1.19"...) for Polaris/Team springs and a distance of 1.25" (start force at 2.5" minus finish force at 1.25"...) for SLP/EPI springs to calculate the overall spring rate?

I was also wondering if anyone know the distance for Team LWT secondary clutch to calculate secondary spring rates? A chart of secondary spring forces would also be super sweet in this thread if anyone has one???

The polaris spring travel stays the same no matter whose springs you use. I think that you may be confusing Cats finish posted by SLP/EPI

I know the actual travel is the same for all Polaris clutches but i was under the impression that EPI/SLP specified the finish force at a different (1.25") distance (height) for their springs...

you are right as I just went and looked at both SLP and EPI sites and they doo show 2.5 and 1.25. I always thought they said it would be more for polaris travel. Can't find that. Same for Goodwins. Sorry about that.

No worries Dave, it's all kinda vague inside my head but sometimes it comes out right. LOL

Also, it only changes the rate calculation which a lot of people don't even think about...

Polaris clutches are all a little different in the 1.19" load they specify. Some are a little less, some are a little more. Now when you index to get belt to sheave, that changes it too. Machining does too. I personally like to get my Polaris primary finish load at 1.25".
