If I appeared to assert that there was one point of seizure, I apologize because there is no basis for that from what I read. That was what I was attempting to convey. I considered suggesting which side spacer might most likely be seized but since people often install the axle from the opposite side, that couldn't be concluded either. Something is clamping the axle to the swing arm or it would turn, that's all we know. I think it is reasonable to conclude that the most likely culprit is the spacer and or bearing holding tension onto the axle to the swing arm on the axle bolt head side/   I don't disagree with anything you have said, other than to conclude that the reason for the axle not turning is one spacer or the other as mentioned. IME, it is seldom that only one are is seized. The barn find comment really nailed the whole issue, Martin. ;-)   I don't recall having to cut a KLR axle but have had to do quite a few others. An old friend loves to garage sale and poke around back roads. He used to buy old stuff, including Honda ATC/trikes and then bring them by to get them going. He was always "going to keep this one for us at the cabin" so I would go through it and then it would be gone when he found one he liked better. ;-)   I can't estimate how many of those I battled the front axle out of. They are fun because the forks offer no reaction/ inertia. I'm not doing that stuff any more as think I've done enough of that for the novelty to wear off. ;-)   ------ Original Message ------ From: "Martin Earl" To: "DSN KLR650" DSN_KLR650@yahoogroups.com>; "Norm Keller" Sent: 2015-03-16 4:22:52 PM Subject: Re: [DSN_KLR650] Re: Frozen rear axle -How to remove?  
Hi Norm, As always, there is a good takeaway from anything that Norm suggest. grin. You and I disagree (I think) on where the axle might be seized...and I would defer to your experience. smile. I keep my 'junk' well lubed and the tires changed often enough that this is not a problem...however, a barn find will exacerbate seizures...I suppose. However, after reading your missive 3x, I see that if the axle won't turn, it is (most likely) the 'A' and 'B' parts. extrapolation from your post would suggest, if the axle will turn, it is in the 92143. My own suggestion only considered the 92143-1060 inner collar.

frozen rear axle -how to remove?

Post by John Biccum » Mon Mar 16, 2015 8:49 pm

Just remembered something relevant: When I serviced the swing arm on my first new-to-me KLR (April 2003) I had a real hard time getting the swing arm bolt out. I used many of the methods we covered in this thread and finally got it out. What I found on the swing arm bolt was corrosion in the center third of the bolt as if the factory installed the bolt with zero grease. My bike was one year old at this time and the PO had run just 2000 miles since new. Then a few years later at a Tech Day I hosted we found a couple more such swing arm bolts rusted into place and they too had the identical pattern of corrosion in the center third of the bolt. One of the tech day bikes was brand new and had gone just a few hundred miles. That made me wonder if the Kawasaki assembly workers were installing bolts that were already corroded. We were servicing the swing arm just 5 months after the bike was produced and yet the bolt was already so corroded it was very difficult to remove. Here is a pic of that bolt: http://johnbiccum.smugmug.com/Motorcycles/Bellevue-Tech-Day/i-rjL9XsQ/A> http://johnbiccum.smugmug.com/Motorcycles/Bellevue-Tech-Day/i-rjL9XsQ/A I realize that the issue today is an axle bolt not the swing arm bolt. But I wonder if the root cause might be the same: lack of lubrication at time of original assembly. Moral of the story: if you have not serviced your swing arm, do it now when the corrosion only makes the bolt difficult to remove rather than waiting until the corrosion makes the bolt impossible to remove.

frozen rear axle -how to remove?

Post by Norm Keller » Mon Mar 16, 2015 9:10 pm

John, that mirrors virtually all the bikes I see. I don't think that we should expect greasing of bolts on an assembly line although spraying with wax or a petroleum film would be ideal, IMO. We're dealing with an inexpensive machine in a market in which even the high end stuff goes together dry. I've also seen almost new bikes with corrosion or the beginnings of that to suspension bolts. There is are several FB threads, as always, on this problem with the suggestion to install grease nipples although this is far beyond most people to accomplish. IMO, any dual sport should have the rear suspension services once per year and more if into deep water. Perhaps others have formed a more accurate assessment of the needed frequency? Haven't had to drill one completely out in some time though to things are looking up. ;-) ------ Original Message ------ From: "John Biccum" To: "Norm Keller" ; DSN_KLR650@yahoogroups.com; "Martin Earl" Sent: 2015-03-16 6:50:51 PM Subject: RE: [DSN_KLR650] Re: Frozen rear axle -How to remove?

frozen rear axle -how to remove?

Post by Martin Earl » Tue Mar 17, 2015 12:33 am

List, One thing for sure, when the center of the swing arm bolt corrodes AND you remove it, it has to be hard on the needle bearings. This is the singular fact is what made me suspicious of the center spacer being the problem on the axle, not the outer spacers. Still could be either, yet I readily defer to Norm's experience. (I would still like to see the sawzall-episode that cuts that axle.) heh. I believe Jeff Saline. removed one such corroded swing arm bolt and it then required bearings; that said, the bearings could have been toast prior to the difficult removal.... m.

frozen rear axle -how to remove?

Post by John Biccum » Tue Mar 17, 2015 2:03 pm

I was concerned about the needle bearings on my swing arm. So I removed them, cleaned them in solvent, inspected them, greased them (Mobil 1 synthetic grease) and reinstalled them. My bearings were still fine but I wonder if I had waited longer what the abrasiveness of the corrosion on the swing arm bolt would have done to the bearings.

List, One thing for sure, when the center of the swing arm bolt corrodes AND you remove it, it has to be hard on the needle bearings. This is the singular fact is what made me suspicious of the center spacer being the problem on the axle, not the outer spacers. Still could be either, yet I readily defer to Norm's experience. (I would still like to see the sawzall-episode that cuts that axle.) heh. I believe Jeff Saline. removed one such corroded swing arm bolt and it then required bearings; that said, the bearings could have been toast prior to the difficult removal.... m.

Just remembered something relevant: When I serviced the swing arm on my first new-to-me KLR (April 2003) I had a real hard time getting the swing arm bolt out. I used many of the methods we covered in this thread and finally got it out. What I found on the swing arm bolt was corrosion in the center third of the bolt as if the factory installed the bolt with zero grease. My bike was one year old at this time and the PO had run just 2000 miles since new. Then a few years later at a Tech Day I hosted we found a couple more such swing arm bolts rusted into place and they too had the identical pattern of corrosion in the center third of the bolt. One of the tech day bikes was brand new and had gone just a few hundred miles. That made me wonder if the Kawasaki assembly workers were installing bolts that were already corroded. We were servicing the swing arm just 5 months after the bike was produced and yet the bolt was already so corroded it was very difficult to remove.

But I wonder if the root cause might be the same: lack of lubrication at time of original assembly. Moral of the story: if you have not serviced your swing arm, do it now when the corrosion only makes the bolt difficult to remove rather than waiting until the corrosion makes the bolt impossible to remove.

frozen rear axle -how to remove?

Post by Norm Keller » Tue Mar 17, 2015 2:54 pm

The needle bearing rollers run against the "tin" outside race, but there is no inner bearing race which is why these are often referenced as "Bremen Bearings" by older technicians. They resemble older back alternator bearings in that way. This type of bearing accepts radial (loads at 90 degree to the needles) loads but have no ability to accept axial loads (loads parallel to the needles). These bearings use an inner sleeve which has a hardened surface as the inner race in the bike's application. The inner sleeve is supported by the swing arm bolt or linkage bolt which accepts the load + the end of the sleeve is clamped against the side structures by the tension of the bolt. I have no way to know what percentage of the load is supported by the bolt and what percentage is supported by the resistance to shear provided by the clamping of the ends. I guess it would be more correct to state that I'm too lazy to calculate as know how to do so and the factors are readily available for reference. ;-) If the through bolt is seized, it will be seized to the inner bearing sleeve and not to the bearing. This is why people start to remove and quickly find that they are able to turn the through bolt. They feel that the turning of the through bolt indicates victory and that continuing to turn will help facilitate removal but a moment's reflection will show that this is not the case. Similarly, if force needs be applied to remove the bolt, the force can only be useful and only applied axially since the bearing cannot provide resistance to movement in a useful (axial) direction. The thickness of the inner sleeve would seem to be far more than sufficient to prevent any effect of ballooning of the sleeve to affect the bearing which leads to the conclusion that efforts to remove the seized bolt from the inner sleeve will have no effect on the bearings. The only way in which the bearing can be affected is if there is some mechanical connection resisting axial movement. Any such mechanical connection must be due to corrosion or similar effects which will, in them selves, be the reason to replace the bearing, rather than the effects of removal. That's my assessment. I've had to replace many rear suspension bearings but always because of damage due to corrosion and such. If someone can present a case for damage otherwise, such as due to removal, I would be most grateful to hear. ------ Original Message ------ From: "Martin Earl" To: "Norm Keller" Cc: "John Biccum" ; "DSN KLR650" DSN_KLR650@yahoogroups.com> Sent: 2015-03-16 10:33:38 PM Subject: Re: [DSN_KLR650] Re: Frozen rear axle -How to remove?
