Hisun ut400 primary clutch issue.

[4x4friend]

I have a 2012 Hisun ut400 that I just bought. I was told it just needed a belt, but nope, all three clutches were shot. So I went online and found a couple videos on replacing the clutches. They stated that the wet clutch and primary clutch should turn easily counterclockwise and harder clockwise because it's turning the engine over. So that is what I'm getting when the wet clutch housing bolts are loose, when I tighten them the shaft now turns very hard counterclockwise. Anyone have any ideas as to the problem?

Make sure the one-way bearing is installed correctly.

Like Greg said it could be the one way bearing. You can try removint it entirely and see if it still acts the same.

It's also possible its the wrong wet clutch. I've seen quite a few for sale from various manufacturers and I've read reports of ones that didn't fit correctly or dont work properly because the size is slightly off. Unfortunately that's an issue with Hisun making slight changes between a bunch of models that use essentially the same parts.
