Got back from town a little while ago. I found the bearings. I bought two different brands. A Timken for $10.80 and a NSK for $8.40 The bearing number is 30203. Timken and NSK had their own personal numbers and letters but both included the 30203. Im gonna put the Timken on the right side and if I ever have to do this again I will see which one is better. I also bought the rubber cups but they were not thick enough. I was going by memory so I will have to return with the stock ones to match them up perfect. Those were $2.20 each.

I saved about $5 over allballs. Not a big savings but I didnt have to wait either. I hope to have pictures of everything up tonight if all goes well.

 

SO Kiss did mud get in the arm or were they just dry?? I mean was there evidence dirt got past the boot? Also...if this is done as PM do you need to buy seals of any kind???

I got the rubber cups changed out for some bigger ones. I still had to modify the inside of it for it to fit. You will see what Im talking about when the pictures go up.

I really wanted to get that bearing out and replace the seal behind the disk brakes. I had some fluid in the swingarm and Im not sure thats normal or not. The service manual doesnt say anthing at all about that. Anyway, that bearing requires a special puller so I just didnt mess with it. I been taking my time with it and am ready to put the swingarm back into the frame now.

Another thing I dont understand and that is one of my smaller bolts that hold the skid plate on goes all the way through the swingarm. The other doesnt but one does. Cant find any reference to this in the manual either, is anyone elses like that?

I dont think anything had got past the swingarm boot. I honestly believe the seal behind the rear disk brakes is allowing the Mobil 424 to seep past it. Time will tell and I can always take that section back off rather easily.

 

KOD
Anyplace on Swingarm to drill and tap a hole for a zerk fitting? That would us to grease the bearings with a greasegun, force water out, & prolong bearing life?[img]i/expressions/face-icon-small-smile.gif[/img]

Actually what I was asking was did it appear the swingarm boot was leaking?? I have seen it on here before that the boot does not seal well and mud/water gets past it and washes the grease from the bearings or was this just a case of them being not greased enough from the get go???

Im pretty sure my boot wasnt leaking. Someone did drill holes seems like all the way through the swingarm bolts and installed grease fittings. That would be the best but I dont have a drill press to do that. At first I didnt understand about the grease fittings being any good until I got the bolts out and seen how they are made. Im gonna stay out of water as much as possible and the rubber cups I put in are better than the stock ones. You will see in my pictures what I mean when I get them up. Hopefully this set will be good for 2000+ miles.

therock, I seen what you were talking about but didnt get a measurement yet. I have some space in there even after the install was done. Thats weird, when I put the swingarm in, it was tight and after tightening down the swingarm bolts a gap developed on both sides. Do you all think thats normal? Can anyone check their swingarm gap for me?

 

KOD<that gap is there on mine as well,,it thru us off on the first attempt to put the arm back on so we took it back off..when we got it on a second time we saw the gap again and decided to look at 5ths 650 closely..turns out that that gap is present on the stock configuration as well just wasnt noticed..it is perfectly alright tho..we checked it very carefully to make sure...if you look at an untouched arm it is the same...I was also able to use the stock rubber gaskets as they were in fairly good shape..the oil in the swing arm leaked out of the gap created by removing the drive shaft..that is normal as well...if any one wants to see what 1000 miles on iungreased bearings looks like check out my pics lol...I think Kawi purposly under greases them...

 

Thanks a lot for that reply. I knew I had put it back right but the gap puzzled me. I left it alone, hooked everything else back up and decided to ask you guys about it. Your bearings are a lot worse than mine was.

 

I have both monday and tuesday off if you wanna go somewhere to see if those new bearings will make it go faster.

 

Tuesday may be a possibility. I wouldnt mind going up Dustins and riding again. We can figure out the trail for ourselves if he doesnt want to ride. That would be a good time to use my GPS for its intended purpose.
