TAPP Clutch Install

Did another run today. Did a few hard roll ons with ambient temps about 80F. Never seen belt get over 195F. Ambient temps at 90F or above are really hard too cool the belt off. Only solution is a lot more air flow.

I'm just waiting for the new Tapp inner sheave fan. It's supposed to move a lot more air. Sounds like they will be available soon

Did you find out if they are doing anything for us that already bought Tapps?

Talked to Jim at Evo again yesterday. They still haven't gotten any direction from Evo on how that will be handled. Said they would also need to get the necessary tools to break them down and rebuild them. They come assembled from Tapp and then they do the setup for customers. So he mentioned they woukd just need to figure out time and costs. That last sentence didn't give me a sense that it woukd be dont for free. I was hoping it would be just the cost of shipping back to Evo.

Seen Sunday SXS YouTube channel said Tapp was sending him replacement parts and a local shop in Phoenix was gonna fo the swap for him. He bought his from Evo. Might be a one off situation for testing and promotion on his YouTube channel tho.

If you plan on keeping the Tapp stuff it might be best to get the tools needed to work on the clutches. Absent Tapp offering to reimburse Evo for time spent I do not see them offering this for free.

Ain't gonna happen. Go watch the videos of the Tapp clutch assembly. They ain't using readily available tools. These are custom tools that they built or had someone else build. Massive breaker bars that are 4 feet long. Not sure why they use them, but that's how they do it. At that point, I'll just pay to have it fixed.
 
Its not to bad.. 30 min tops. Evo sells the tool needed to hold and disassemble.. You will need a torque wrench up to 130 ft lbs. One big socket 1 9/16. And a torch. And of course loctite.

Yes, I got the sheave from Tapp. Holder and spider wrench from Evo.
 
Did you buy the clutch from Tapp? Did they charge you for the replacement sheave?

Tapp has been very responsive through email. I purchased the primary and secondary through Evolution Powersports. Yes I was charged for the sheave. I would expect Evo to get there arms around these sheave swaps for customers soon. Not everyone will be willing to change these out themselves, nor buy the parts to do so. Btw this definitely moves more air!

I was able to talk with Tapp this morning. They are shipping sheaves out to suppliers and have a few for customers who bought direct. They had discussions on cost and said they would be charging about $350 for the sheave and labor to swap it out. That's not too bad, but I was hoping it would be no charge for the sheave. So with shipping you're probably looking at $400+ dollars.

He said they have a local company in Mesa, Arizona for those in the Phoenix metro area. KBR UTV can do the swap in about 1 hour. I'll probably just bring mine to them.

$350 for the sheave is not too bad if you consider the time and cost machining that part and getting them shipped from Canada.

It looks like all the current aftermarket primaries now have big fins to move the air.

Tapp said the clutches are machined by another vendor, so I'm sure they are eating some cash too.

They more or less admitted the testing they had done was cold weather and I think Evo's was mostly dyno work with no cover. Evo even said in one of their videos the guy doing the testing in Glamis "liked to run with the cover off".......that's cause the only way it stays cool is cover off.

La Rue figured out the same, even though most people claimed they were not have heat issues.

They just didn't do the testing right. Too quick to assume everything was the same as a previous clutch.
 
Another thing to consider, is the sheave diameter is much larger. I first thought I had the wrong sheave, but realized the bigger sheave has bigger fan blades.. its as big as you can get without hitting the inner housing. The belt just doesn't ride to the top. I can say it moves alot of air now. Seems more than the RPM fan at idle. Definitely more at higher rpm. I think the fins will act as a heat sink also.

Yeah, the larger fins are critical. Even the stock primary had some pretty good sized fins. The stock secondary should have had some as well, then you'd get a push pull effect to get more cfm through the CVT. Well see if Kawasaki addresses that. If not, I'll add the secondary before dune season.

This is why I am in no rush to jump to an aftermarket clutch and will wait to see what Kawi comes up with for the fix. Belt life in the dunes did not seem to improve much with a Tapp primary. It seemed to me the Tapp secondary was making improvements, but hard to tell as everyone had to run with no cover.

I am curious to see what type of secondary Larue comes up with for the H2.
