Well, I got this beast with 2700 miles on it to see if if ATVing is for me before going nuts on a newer unit.

The trans feels like it slips somewhat at low RPM, when starting out, but once I have it rolling and stand on it, it does not slip. Is this the nature of the beast? I'm 350 pounds, so I belive I'm on the edge of what this machine wants to handle.

ANd what can I do to stiffen up the springs in it? I feel like I'm going to either dump it or go over backwards half the time!

Otherwise, I love my old cat, very simple machine to work on,.

 

If the machine is a manual trans then adjust the clutch to fix the slipping issue. If it is an auto trans then you can put a clutch kit in makes the clutch engage better. But it can take the auto trans a second to come to full RPM on take off.

Now if its a 1999 and given the weight of the machine I would guess the shocks are bad or possible leaking and the springs are weak. This happens due to the weight of the machine. You can also check to see that they are adjusted all the way up as stiff as they go. Your machine has the same size shocks as the 400 from 1999 to at least 2004. You can ususally find them on ebay fo rlike $50each (shock and spring).

Hope this helps

Okay, I'm going to try to adjust the clutch. I don't have a service manual for the thing, is it a simple job?

It's a five speed manual with the automatic clutch.

 

Try searching the site here for clutch adjustment. I thought I remember seeing a post with pictures.

If you still can not find what you need PM me an email address and I will email you the pages for the clutch adjustment.

You should not be getting any kind of slipping sensation with the manual. Sounds like the clutch plates are glazed/worn and are slipping to me.

Do yourself a HUGE favor....if you are going to do the clutch repairs yourself, get a factory service manual (not a clymers, etc) They are much better to work with, as they have clear illustrations and torque specifications, etc. The professional mechanics use them, that's reason enough to spend the $30-45 bucks for one

 

Lastchance,

Ok, if I did this right attached to this should be the steps to adjustingthe clutch on an AC 400/500.

I would have emailed it to you but somehow I deleted your PM.
