hello all,

How do I remove the pivot bolts for the swingarm on a 99 scrambler 4x4. they look pretty big like around 46mm. I would like to know what socket / wrench to use. Also, does the cvt stuff need to come off before I can take the left bolt off?

Thanks,

Bobby

I just changed the swing arm bushings on my 2006 scrambler. It is a fairly big job. Both clutches have to be removed in order to access the left hand bolt. The drive clutch requires a puller from polaris which cost $70 canadian. Having done the whole job I discovered that most of the play was caused by the right hand bolt being loose. The shank of the bolt had become worn against the frame so I replaced it, $18. The bushings where really not in bad shape. To make a long story short, before you start tearing into the bike check the torque on the easily accessable right hand bolt. It should be 150 ft lbs. The right hand side being the thrust side will likely wear or come loose first. Remember Loctite is your friend.

Cheers,

Dave

yes your primary and secondary clutches will have to be removed and the backing cover (behind clutches) to get to the swing arm bolt what i did was go to lowes and bought a 1 3/4 socket (6 point cheapy) then cut off the end where the ratchet gos on and welded a 12 inch piece of 1 7/8 pipe on it then welded the end that you cut off on to the other end so what you have is a very deep socket this way you can use it for the swingarm and that nasty rear axel nut and be able to use a impacket to do either job,i think the socket was like 6 bucks very well worth it!

I no this is a older thread, but I went to Change my rear swing arm bushings while the shock was out getting serviced. And this thread was some what helpful but I am a handy person. For those that might not have messes with this kinda stuff il break it down.
First thing I did was removed the clutch cover. I removed the bolts that holds on the clutches. Not haven a primary clutch puller I took a sledge hammer and beat it tell it fell off....just kidding. I loaded up the atv and went to my local Polaris shop and he pulled the clutch off for free. I did see the pullers going around 30 on eBay.
So now I have both clutched off. Remember how it all came off! There is a little washer behind the secondary clutch.
Next remove 7 screws that hold that back plate on, pull it off. On the right side remove 4 screws that hold on the Guard.
My rear shock was already off, you should get away with just removing the bottom bolt. I had to cut mine off and buy new bolt and bushing. Also remove your rear brake.
Ok now I grabbed the 1 3/4 socket, ratchet and Extension. I didn't have to rig up any special tool to fit in there but not every one has this kind of tools.
Both sides broke loose very smoothly, Proper tools for the job!

Ok so now I pulled the swing arm out, the left side is a easy change of bushings.
The right side I grabbed a 24" pipe wrench and a 1 11/16 socket I believe. And broke that assembly apart. Replaced the bushings on both sides and tightened it back up.
I cleaned the area and greased it very well.
Installing it all back up is pretty much a reverse process. Please use lock tight on every bolt and grease the fittings.
I don't know Torque settings as I just roughed it.

Notes: while swing arm off clean it up really good

I'm replacing chain and sprockets
Changing the front is very easy while swinger is off.
This is my first write up, so about lack of details ...

My rear wheel alignment seems to be off. What's the best way to check for this and what would the causes be? Worn out bushing?
Thanks

Grab it by the rear rack and yank it back and forth, if it's worn, easy to see the movement. I had a machine shop make bronze bushings for my 97 Sportsman. It's a bitch of a job, but you won't believe how much better it handles. Those plastic bushings are junk, imho. Good time to replace chain and sprocket if they are worn. Check tightness of all engine mount bolts and transmission mounting bolts. Yes, locktite everything. 2 strokes loosen everything if not locktited. Machine shop charged me $55 for 2 bronze bushings.
