I changed the oil in my fourtrax with automotive motor oil (before I purchased the manual and learned how the wet clutch and friction modifiers work). I drained the oil and filled it with Honda GN4 and the clutch still slips if under load. Is there a way to "flush" the oil out? I didn't change the filter as it was only in there for about a day.

You will have to change it about three times and I would change the filter also.

If that don't work, you will have to replace the fiber clutch discs. If you've rode it much after it started slipping, it's probably too late.

Okay, seems to be only be slipping when under load. I'll see if I can wait until winter to replace them. Anything else I should check or replace when I have her all ripped apart?

 

[Helmut]

Make sure you soak the new clutch discs in new oil before installing them. It probably wouldn't hurt to go ahead and replace the clutch springs, since you will have them off anyway.

Its also hard to shift, would replacing the clutch springs make it easier to shift?

When you replace all that was mentioned above it should shift ok.

After you replace the parts, you will need to adjust the clutch free play.

The manual shows the centrifugal clutch needs to be removed first (since its in the way), and that requires a clutch holder. To remove the other clutch the manual shows that a clutch center holder, lock nut wrench, and extension bar are required. Are these tools really required? If so, where do you recommend buying them? I'm guessing the dealer would charge alot for the tools (since they would rather charge you to change the clutch).

Thanks

If you use an impact wrench to loosen them, you can usually hold them with your hand. Sometimes you can't hold the centrifugal clutch with your hand, but you can clamp a pair of vise grips on it in a certain place without damaging it. I usually just tighten them back up with the impact wrench, too, but you're not supposed to do that. Personally, I've never had any problems from doing it that way. Those tools would make it a lot easier, though, especially the tool to get the fiber disc clutch off with. It's hard to hold, once you remove the coil springs. If you try to hold it with a pry bar or screwdriver, the soft aluminum parts will break easily.

Remember, the centrifugal clutch nut has left hand threads.
