Thank you! I am in serious need of some help right now. (sorry to finally make an intro and post up in this moment of crisis... I have been lurking and researching since I joined lol)
I am putting the swingarm back on right now and am having serious trouble wrapping my brain around how I can put 72 ft/lbs of torque to a bearing.
rewinding a bit... even though the swingarm exhibited no play, I pulled it to replace the bearings as a general refresh. Upon inspection, I decided to regrease and reuse the bearings because it appears the bike was well maintained. There was fresh, still green grease on the universal.
So I put the swingarm back up in place, centered it, and went to torque the right side. It felt like I was turning the same resistance, then BAM the bearing exploded.
I pulled it back out, pulled the race and replaced the bearing with new. I did the other side too so they were both new.
After hours of searching (not kidding lol) I decided to try again. Every other ATV or motorcycle swing arm job I came across that uses a similar system uses only 12-15 ft/lbs on the bearing, and both sides have a locknut. Not just one like the goldwing.
So nervously... I put the swingarm back up, make sure both sides were snug against the bearings and began torquing the right side. At around 20-30 lbs of pressure, the inner bearing pulled through the dust cover accompanied by a POP sound that was the seal spring exploding.
Now I'm stuck. I still have one good bearing that came from the left side for a third and final attempt... but what am I doing wrong??
I am not new to this kind of work... but this whole applying 72 ft/lbs of torque to a bearing is blowing my mind. And my bearings haha. What am I doing wrong? I am following the factory service manual. Am I missing something? Does the swingarm need to be all the way tight to one side of the frame or the other? I have it centered (about 1/8" gap on either side)
