2002 scrambler 400 4x4. I am having problems with my rear swing arm PIVOT Bolts coming loose on me. I have no problem tightening up the side with pull starter, but the other pivot bolt is tucked behind the PVT inner cover. My question is how do I get the Drive clutch off so I can remove the inner cover, and tighten my swingarm bolts. Do I need the special tools that the manual calls for or os there another way. I have removed the center bolt from the drive clutch but the drive clutch did not want to pull off easily. Also will the drive clutch stay in-tact when I puill it off. Any tips or suggestions would be great.

 

to get the primary clutch off you need to get a primary clutch puller. The secondary should come off without needing any special tools.

 

Where do I get the puller i am not sure i have access to one, is it absolutely necessary?

 

i got mine from my dealer, HPD sells one for $19.95 HPD you will need it to take off the primary clutch.

 

Any of your buds have a Polaris snowmobile? One of them should have one.

 

The threads are 3/4 inch fine thread pitch. You can use a bolt with a nut welded on it, OR use a trailer ball with that thread, and a 3/8 extension, if you dont want to buy the puller. Also, the swing arm pivot bolts are suppose to have loctite on them so they wont come loose

 

are they loose or are the bushings toast?

 

I think they are just loose, the pivot bolt keeps coming completly undone on the chain drive side of the quad, I want to take the PVT apart just so I can check if the other side is loose. The pivot bolt will literally fall out, I used a ton of red loctite and torqued it to 150 ft lbs this time so i hope it should not fall out again. Last time I used a hand ratchet to tighten it, so I don't think I got it near tight enough.

 

How do i tell if the bushings are shot?

 

there will be play

squeeze the chain against the swingarm with your strong hand,,,you should see the play if there is any

mine need to be replaced
