Thanks for the tip on the bearing at BioMetrics. I did check it out and may go that way, but my main concern right now is getting the bike ready to depart for Sedalia on the 17th. Unfortunately the supplier is in Cali, and overnight shipping is as much as the bearing ($75).
I pulled, disassembled and cleaned the final drive this evening. It wasn't that bad--started about 9:40 PM and finished about 1:00 AM. Took my time, cleaned everything thoroughly. The hardest part was removing the bearing. My puller didn't quite fit in the gap, so I had to do some grinding, and even heated to 200 degrees, I really needed to torque down to get it to budge.
It's off though, and good thing. Both races and heavily pitted. Everything else looks fine--even the seal I plan to replace anyway.
I'm at the mercy of parts availability, so my game tomorrow is to call around and see who has what. I can't get there until evening, so I'm working around store schedules. Battley's till 7 PM T-F which is nice, Bob's is open late on Wednesday, Morton's late on Thursday. I may need to make two runs for parts, since i won't know what size shim I will need until after I have the new bearing installed.
And my K has 40,000 miles on it--not a lot given the heart ache it's given me. Admittedly, I ride hard commuting and it's been to the track a couple times. But it gets regular maintenance, and honestly, these problems with main seals and the final drives shouldn't be happening and they surely aren't "maintenance." Reliable engine seals have been around for decades, and you don't hear FJR, ST or GoldWing owners having driveline problems.
It's love-hate with the K. When it's running well I love it, but at these time it is trying my patience.
