There are a couple threads running on this topic or the seal at the moment, but I didn't want this info to get lost. It might be worth putting in the tech notes.
5Twins posted a link to a bushing from Mcmaster-Carr that is about 1/2 the price of the one from Mikes, and for those of us on the east coast, they ship fast. I get my orders next day if I order before noon. Here is the link to the M-C bushing-

Both the M-C bushing and the Mikes bushing are 10mm long. I noted that I had 12-13mm of counterbore in my shaft where the bushing lives. So I ordered 2@10mm and 2@12mm, plus I had one on order from Mikes before the link to M-C showed up. The thinking here is perhaps the 12mm long bushing might provide a larger wear area and reduce loads on the seal.
Edit by gggGary 1-8-18 Don't use a 12mm long bushing! read here. [URL="http://www.xs650.com/threads/clutch-pushrod-bushing-interchange-thread.30549/#post-535244"]Clutch pushrod bushing interchange thread[/URL]

So, my bushings and seals from both sources arrived today. The first pic is Mikes bushing on the left, and the M-C bushing on the right, both 10mm. The only visible difference is the numbering. The second pic is the 10mm Mikes bushing and the 12mm M-C bushing. The 12mm bushing went right in and fits perfectly. 3rd pic.
SEAL INSTALLATION NOTE-IMPORTANT!!!
I suggested on one of the other threads that Permatex 2B might be a reasonable sealant to apply to the outside lip of the seal. I WAS WRONG!! The stuff gets too sticky, and the seal will not go in happily at all. I ruined the first one. I'm thinking now that simple motor oil or maybe dish soap(a trick for putting in 2 piece rear main seals on car engines) is the ideal-it wants to be slippery to allow the somewhat tacky rubber to slide home and into place.
So there ya have it. I now have 3 10mm bushings and 1 12mm bushing extra if anyone is in need, otherwise they'll become inventory.
