mine has sort of the same problem. when it is in gear, it will just roll as if it was in neutral. let me know what happens with your machine and how much it costs!!

 

That same part has been known to fail on Ranchers, and Foremans, too.

If you got into the machine for next to nothing and this is the only fix it needs, I think you've got a heck of a nice quad for very little investment.

 

I had rubcon 500 like yours,the rats eat up my wiring harness and caused shifting problems for me,of course my problem does not sound like yours,I fixed my wires with but connectors this is a very good atv I liked the transmission better than any other but be warned its a gas hog I traded mine in on a trx420 because of the gas consumpsion the trx is no where as good as the 500 was just better mileage.

 

Progress has been slow but I thort I better post somthing incase anyone was interested.
Got a shop manual ordered, $26.00 of the net. Pulled the plastics off the front of the bike, Pulled the front diff forward just enough to drop the drive sharft, Removed the gear linkages and motor assy control.
Drain the oil, Remove the filter & remove the clutch cover. Made a big oily mess. As it turns out, there is a suprisingly large amount of oil still left behind the clutch cover.
Looks like the clutch has deffinatly seen some heat. I looked into having a puller made for clutch removel, $147.00. I looked at just having a 40 x 1.5mm thread cut on the end of some round stock & finshing the rest myself, $65.00. Genuin honda puller, $150.00.
So I think I will bite the bullet & take it to the local honda dealership, Hopfully they dont scruw me for a 5 min job!

Will post more when I have more to report.

 

I've heard a person can remove that with a regular 3 jaw puller by wrapping a ratchet strap around it, but I've never tried it.

You might be able to find the right puller here, cheap.

Honda I believe has a purpose built holder for the clutch while you take the nut off, but it looks to me it would be easy to fabricate something. Others just use an impact gun, but I'm not too keen on that idea.
