[QUOTE="Tom Cox, post: 902333, member: 42215"] [b]KX Lower Shock Mount Bearing[/b] For those of us talking about the short life span of a Kawasaki lower shock mount bearing, the problem stems from Kawasaki's design. The original seal is designed to rub against the aluminum opening in the linkage knuckle as the linkage goes through its travel. This wears a groove in the aluminum so the seal, even a new one, is not effective anymore. It doesn't seal against anything. I recognized the problem on my 92 KX 250. What I changed and have used since, is using a correct diameter wrist pin, I machine the length to span the width of the lower shock mount yoke opening. Also the ID of the wrist pin has to be of the correct diameter to accept the mounting bolt. I then purchase seals that are the correct OD to be a tight fit in the linkage knuckle opening and then the effective seal is around the wrist pin bushing. The seal is now on a hardened machined surface and not a rubber seal lip wearing on aluminum. The wrist pin I get from Weisco. The seal from a local bearing / seal supply house. I've done this to all my KX or KDX machines since 1992. This fix doesn't make the bearing last for ever, its a pretty harsh environment it lives and works in, but I'm not changing the bearing multiple times a year. I grease it a couple times a year and change the seals when I grease it and probably on the average change everything out every other year. I know people that don't perform maintenance on this bearing until its gone because they know its going to fail fairly regularly. [/QUOTE]
