Welcome to the new and improved Proflex / K2 Tech Forum!
Simon thanks for the repost on the sealed bearings. can I assume this assembly works on the OzM frame? The biggest challenge would be the fabrication of the axle. I think all the other parts would be easily available. I have disco monkeys with the needle bearing assembly..wonder if there is a way for that system to work on the Oz? thanks again! Henry
Hi Gang, Thanks for the replies. The arm does drop with the pinch bolts loose and I believe the o-rings are in their proper place though I did pinch and sever one on my first attempt. I am just a little puzzled on the directions for the axle bolt..It said 250 In Lbs (approx 20Ft lbs) and when I get close to that torque the arm does start to drop slow (have resistance) even with the pinch bolts loose... I am guessing that I should snug up the axle bolt to no play and easy smooth motion of the swingarm and don't worry so much about the specs on the torque and then snug up the pinch bolts to a slow smooth drop of the arm and then just keep an eye on things. Any follow up on this is always welcome and I have some other questions but they are a new topic..Parts are coming in and the build is under way!

The "x-rings"(rubber O-rings) are available at McMaster.com.The axle bolt is the big sucker that goes thru the frame and should be tightened as hard as possible. The way I do it is to pinch the opposite bearing until the cup won't spin, and then wrench it as tight as you possibly can. Then loosen the pinch bolt and work the swingarm drop. The cups should never move or disaster will follow.The fabrication of the axle should not be as much of a chore as having the swingarm reamed out to fit the bearings.Let me know if you have a tool for reaming the swingarm.TerryHi Terry, thanks for the info.. I am going to give the bushing system a try before I convert to sealed bearing but if I do go for the conversion I will get in touch with you. Since I did pinch a seal/O-ring on the first rebuild attempt would you happen to know the McMaster part or Catalog number..always good to have spares! Have completed assembly and taken her on a few good rides and swingarm is working great. There is some creaking but not real sure if its the swingarm but when I got caught in the rain on sunday and I noticed the whole bike was very quiet...hmmm.. my cable cover ends are metal so I think I am going to convert to the plastic ends and do the quick 5 minute lube/check of the swingarm..as mentioned elsewhere in the forum I am considering the deep cup Pig DH pro headset so that maybe should narrow down the creak and squeak... really startin to like the bike..hope I can quiet her down..
