Rear Axle

[racer11]

So I bought a 96 750 a little while back. when riding i had a high speed weaving problem. I found out that the rear wheel was not aligned with the bike. I did some adjustments and got the bike to ride better. I noticed then that the axel would keep sliding on its own to the wrong position if I had the axel bolt torqued correctly. Only way to correct this was to tighten the sh** out of that bolt. well now the cotterpin dosent even pass through the nut. there is like a 1/4 gap between the cotterpin hole and the the nut. i took the wheel apart and all bearings and spacers are in place. it seems that 1/4 of an inch is missing between the swingarm sides. i don't understand. anyone have any ideas or have this problem as well? also the sproket side seems to be real close to the swingarm.

Best bet is to check out the parts fiche and make sure you have everything that it lists. If the cotter pin won't pass through the castle nut... it sounds like there is something there that doesn't belong... or is in backward.

I agree -- odds are you're missing a bushing (spacer) or have it seated incorrectly.

Check out the parts fiche here:

I think that you could have reversed #9

theres a torque spec without the cotter, you don't "need" that.

Oh, one other thought -- are the chain adjusters flush to the rear of the swingarm AND undamaged? Normally when a wheel pulls off-axis, it's because the adjusters are loose, and in the process one of the adjusters gets damaged as well.

Also, I carry the bandit upgrade adjusters.

One thought also, JDumont can attest to this. He was experiencing the rear tire movement. Felt like the tire slide. When I went to cut the chain off we removed the tire and removed the sprocket from the cush drive. Anyhow, the spacer inside fell right out. Its possible it might have been in backwards. One side is longer than the other. If its in backwards, it will allow the tire to float side to side. Since his fell out. We never were able to tell if this was the problem. But we both agree that it had to have been, Since the problem hasnt reoccured since we reinstalled it correctly.

Something to check.

Yea I had posted a while back that after my new tires were mounted and I reinstalled the wheels that it felt "squirrelly" in the back end. Being a newbie I wasnt sure if this was due to the brand new tires not being worn in or something else. I knew everything was tight and then surmised that I put the long spacer in there backwards. There is a flange on the spacer but it isnt centered. I imagine that installing that backwards would allow some slop.

Like Newbie says, since we did the new chain and sprockets the other day I havent noticed anything odd at all...

[racer11]

hey thanks for all the help, the chain adjusters look good, steves had a good idea with that #9 in the parts layout. I will check that out soon and see if that is reversed. That could make sense. I will make sure all spacers are in correctly too. What is the number for that spacer Newbie2it mentioned in the parts layout? Also, the swingarm has marks from where the sproket bolts have contacted it so thats how close it is.

[Court93kat]

If the wheel has been shifting from side to side those bolts will make contact with the swing arm. Once you fix that, they shouldn't hit anymore.

[Newbie2it]

I dont honestly beleive there is enough movement on that spacer to allow the bolts to come into contact with the swing arm.

It is Part # 9 on this fiche. Its called a retainer but its just a bushing. Well, it retains the tire on true track LOL So I guess the names right. The fiche shows the correct orientation.. long side vs short side.

[Court93kat]

From the original post......

......I noticed that the axel would keep sliding on its own to the wrong position......

If his tire is moving in the adjustment slots then he WILL have contact with the swingarm from the sprocket bolts. When the wheel is straight and tight, there is not a whole lot of room between the sprocket bolts and the side of the swingarm. Now, add in the fact that one end is moving in the adjustment slot.... there will be contact.

My '90 750 had the same problem with the castle nut being too far in for the cotter pin, so did Gytr's pre 750. I'd found a split washer the appropriate size and put it behind the castle nut and that cured the problem. Did the same to Gytr's Kat a few weeks back when he was here. Hope it worked for him too. the way Black_Peter eyeballed up both bikes i'd have to believe everything is in there, and correctly. I know i studied the pics in my Clymer putting it all back together.
