08 Crank Bearings

[PEB]

Getting the bearings has turned into a mail order adventure. We will pry the seals out and clean the grease out. The cases have oil passages that go to the outside of the bearing answering the question earlier about how the seals keep lubed. I guess we should get confirmation the holes are the same for sealed non-sealed bearings. Can anyone chime in on this?

They should be. You can also check the part #s of the cases. I've never seen an '08 with the jug off.

I can think of one reason to leave the seals in.
Drownding the bike....that's probably why I haven't experienced any lower-end issues at 189 hours.
My bike went for a dip during a flash flood down pour (60 hrs)...hydro locked right up.
You wouldn't believe the crud that got into the motor, I did several heavy flushes with diesel fuel until it flowed clean.

We ended up leaving them in. The bike drowning would be a reason to leave them. OF course the water would still get at the lower crank bearing. I will post up some pic e of the bearing i took out. Looks like ball bearings on both sides. One has what looks to be a composite cage.

paul,

Next time contact Worldwide Bearing in NJ. They are an MC engine bearing specialty shop, and used to supply GGNA years ago. High end parts at less than OEM price. You could go with the unsealed two piece roller, or the "M" series radial ball bearing with extra ball and machined brass cage.

Crank seals should be the same, only the bearing types changed over the years. Get the countershaft sleeve and orings as well.
