After putting our new machined sheave on this forum and not getting much response, I was thinking well maybe I can't assume all Viking owners are past rhino owners and know what a machined sheave is or what clutching this Viking does.
Who needs any of it?
Clutch kit only., actually I think no one because the benefits you get from the machined sheave and the kit far outweigh the kit alone but I will address it.
Anytime you put heavy or larger tires or lots of heavy accessories on a Viking you drop engine rpm and put heavier loads on the clutch, which mean less performance and higher belt temps.
So you need lighter roller weights in the clutch to bring what is called shift speed up, or another words the engine RPM back up that you lost with the heavy tires or weights. Then the stiffer secondary spring is to give more belt grip, faster backshifting for hill climbing and to slow the shift out down so you stay in "lower gear" longer for better acceleration.
So what does the sheave do? Basically it just manipulates the belt to run lower in the primary on take off for better low end, gives you the power you need to get the bigger tires going and better low end overall. Then it is machined to get more belt travel up on top end and that is why the Viking we were testing was running 58 mph and only 7300 rpm which means with the right mods you could run in the 60's with the machined sheave.
So just like a rhino, the machined sheave and clutch weights and spring are a great addition to the vehicle. I would dare to say we have sold more machined sheaves than anyone now we over 2000 sold. Been at this a long time.
If you have any questions, call me at the office. In the mean time make sure you read the tech article on the sheave on our site.
