One of the main reasons a new push rod seal will fail is if you didn't install a new clutch pushrod bushing at the same time you installed the new seal. If you can get your hands on a Mikes xs catalog, it explains in detail with photos exactly what you have to do to install it correctly. If you have installed the new bushing and seal at the same time, then you need to go back over it again. Hamamatsu

I've replaced the clutch pushrod seal in my XS650B three or four times now. I finally realized that it is leaking between the seal & the engine case, not around the pushrod. I have deburred the edge of the case to help prevent shaving the rubber off the outside of the seal, but that didn't help. I've been thinking about using some kind of gasket sealer when I put a new seal in. Any suggestions?

Yep. Three Bond 1104 (same as Yamabond #4). Mike's XS has it. Sometimes a little treachery helps with this job; popping a frozen seal into a hot case helps.

I must have been lucky on mine. I followed Dwayne's, from 650 Central, on using my pocket knife to trim the edge of the hole it goes in. I don't remember any "Bushing" where the seal went, You said there was a link on MikesXS?

Yeah, they differ. I've done that seal on a bunch of XS650 engines; some popped right in without trouble, others were difficult. The bushing is back in the case behind the seal, and has to be pulled by drilling. It's not a real common problem. If the bushing gets so worn that the rod rocks and wears the seal prematurely, it's time to replace it (and the rod too if it shows wear at that contact or is deformed). Mike' XS has procedures and visuals on the site.
