One thing I want to reiterate with more doing sheave work is the primary bearing support bracket or spider cage... this piece:

If you re-grease/repack the bearing, install it a couple times fully seated over the primary shaft and remove it and make sure the hydraulic pressure doesn't push the rubber seal up, bending the seal retainer bracket.

There are two thin-walled positioning sleeves installed on the longer bolt locations. Those sleeves are a tight fit and it's possible to install the bearing support cage skewed because the go in cockeyed. I now grease them so they go in a little easier into the holes. When I'm installing the bearing support cage I'll put it into place and gently tap it into place with a rubber mallet on the center to make sure it's fully seated before installing the bolts. I then install the bolts by hand and they should bottom out all the way with little resistance and it then only takes a couple turns of my ratchet to tighten them.

If you don't bottom out that bearing support cage first and use the bolts to seat it, that's when you have the possibility of installing the bearing support cage cockeyed. The results of either the rubber seal\retainer being cockeyed or the bearing support cage being cockeyed can mean an early wet clutch death. On my X4 one dowel was stuck in the cage and one was stuck in the CVT metal boss so it made it harder to install correctly. The sleeves are so thin, handling them with a set of pliers mars them up.

Thanks Massive. This good info before I install my new sheave. I was planning on using my cordless driver and after reading this, I won’t be.

Just finished my install of the Hunterworks sheave and 18gr weights tonight as well. It just turned midnight here so I won’t be running it until tomorrow sometime. Great service and fast shipping. Got it Monday but didn’t have time to install until tonight. Total time was about 2.5 hours. Not bad.

I just took it for a burn down the road. I did three runs. Two into the wind (about 5-10mph) and one with the wind. I’ve got the full glass OEM windshield and the rear OEM glass. I used the gps app on my phone.
1st run 63
2nd run 63
3rd run 64
All seem consistent with others. Cruising at 30-40 is definitely quieter and cruising at 50 is no problem at all. Almost feels like half throttle although it’s not.
Throttle response is greatly improved. Stomping on it at 20-25 breaks the +28” tires very easily. With the little bit of running I’ve done, I’d say I’m very happy with the results and it’s a pretty easy mod. Cheaper then the pipe as well but I’m glad I’ve got both [emoji4]
