Partially Restored 74 CB550
Laverdaroo:
Get it done it’ll be sorted then. Just make sure you’re fastidious with the clean afterwards. The bottom case is the easier if the two to clean anyway. Both my engines have been vapour blasted and cerecote’d and zero dramas.
Can’t spell cerecote

The clutch side bearing stays on the primary drive shaft Dave, it will just slide into place as you knock the primary drive shaft into place. Just don't forget the spacer that goes onto the primary shaft when you're fitting it. Also don't forget the bearing plate to stop it coming back out.
Embedded???? How hard to you think the media is? it's a lot softer than the alloy and they'd be out of business soon if that was to happen as engines would be failing all over the place, you may be confusing that with being trapped, if you leave a pocket of grease somewhere by not cleaning the case properly then the media will just stick into that and heat would release it later, so long as the cases are very clean (and by that I mean check every oil gallery) you'll be fine. A good clean after, just to make sure, using bottle brushes etc and a visual check down oil galleries and that should do.

Got to decide whether to get bottom cases vapour blasted today. Only reason is to prepare the small proportion of visible outer surfaces for paint/ ceramic prep. Have heard that media gets embedded then releases when engine hot. Doesn’t seem like a worthwhile risk , though others have had it done without problems. 2 months I’ve been vacillating !

If you don't want the hassle of cleaning the cases yourself, you could always have them soda blasted. That process will allow the cases to be washed and thus dissolve the soda. Can't remember but I have a feeling that Roo had that done. I am about to have a pair of cases done that way and then Cerakote'd
Matt_Harrington:
Ignore that! Spoke with Nathan (who Roo and I use) and cases are dipped in paint stripper, washed, vapour blasted, air/water cleared passages and then washed again. Dried and then cerakote'd.
