If you are going to have it worked on, consider upgrading it somehow. Bore it to a larger bearing, one more easily available or available in better qualities than the junker you are stuck with from kawi.
Maybe a bearing replacement material..teflon or somesuch would be good to consider.
This bearing is pretty much failed all the time. I have serviced my link as often as four times a year...and ALWAYS had to replace that bearing until I started using a special (read: expensive!) grease (Hydrosyn-70). Now I get a couple of regreasing efforts out of the puny thing.
Look at a brand new one from Kawi.....you will see that the rollers are crooked in the shell from the start. Too much space!! A new bearing doesn't 'roll' for diddle, let alone a bearing that has been pounded, dragged thru mud and water for hundreds of miles.
imo and all that.......
