Hello

i'm new to the forum, so hello everyone. I'm from Lisbon, Portugal
Im the proud owner of a 2020 cforce 600 EPS and i noticed something the shifting is kind of hard, when the transmission is on load, also i hear some whine on deceleration. All of this inclines me to the clutch bearing.
Had anyone deleted the one way bearing and swapped with a regular one? Scooters and other CVT vehicles i know don't have them

No one I know but I assume you can get the bearing for any that are over 600cc as they are just bearings and see. I am thinking that the bearing or oneway doesn't even come into play until the belt sets down on it..something below 9mph and the primary releases the belt. If it were mine I would check the oneway for a problem like seizing..lack of lube.. and that the primary and belt are not touching when at idle or stationary. It may just be shimmed or aligned wrong. As for the whining...may not be the clutch system. May just be the rest of the drivetrain. But check the other things first.

Yes, just saw a video from a cforce 800 and it's just a regular bearing.
I own a 300cc honda scooter and i have engine brake almost until it stops, around 5mph the clutch disengages and lets the belt rest against the axle bearing, on the cforce it should work the same. I will try it out

That's been the oddest thing for me to figure out, the CVT belt drive set up.
I'm used to driving full on manual shift or older type auto transmissions.
My Harley is old school 4 speed, My 74 RC is old school four speed.
My car is a five speed, my previous parts runner was a five speed.
I learned to drive in a five speed.
Little bit of a learning curve on that one, but I'm getting it figured out and it's seems to be a pretty solid setup.

Here is a video of a guy doing just what your talking about on the same machine.

It's nice to know you could take the spragg assembly out of these units and keep going. The reason they don't put them in heavier units..like above the 600 ATVs is as you see, it's just too light-duty. And I think I would lube the bearings it with something more then just silicone spray though. But that's just me. I'll almost bet if you took it down to a bearing supply house they could match it up with just a solid bearing like a National or a Timken. Even one slightly narrower could be shimmed. Just thinking out loud.

I'll put this video in the How-To videos. Thanks mpgo4th for posting this. It will help lots of people.

took the transmission apart and there is no one way bearing, just a regular bearing.
I still have engine braking until around 4-5mph. On steep descents i have to keep giving it some throttle so the clutch don't freewheel the belt

The 600s are supposed to have them..ie Overriding clutches and they are not in the transmission, they are in the Primary or drive clutch. If yours spins both directions it is either broken or the wrong one for the machine. Personally, from what I have been hearing, I would want just the bearing.

i will order a new one way bearing and see how it hold ups with periodic greasing.
on slow more technical descents is annoying when the clutch disengages and i have to get to the brakes
