With the O-ring there's no need for a gasket. Perhaps they were unable to achieve sufficient endplay without one (using three of the thinnest shims, which are .24mm (~.0095") thick - there's really no harm in using only two shims, but "three and only three" is entrenched dogma). The "right" way to deal with this situation is to have a few thousandths machined off of the flywheel's thrust surface rather than adding a gasket.
Ideal endplay would be between .004" and .006". You need to verify that the thrust bearing is not moving in the case before attempting to reduce yours. Say it was originally .005" and is now .009", that would mean the bearing is walking by .004" - if you reshimmed it to get .005" again, there would actually only be .001" between the moving parts and in all likelihood it would seize in short order. Have a helper clunk the crank back & forth HARD while you observe the thrust bearing for movement. Placing your fingertips so they touch both the case and the bearing flange may enable you to detect movement that you can't discern by eye. If the bearing IS moving, leave the endplay where it was (.008-.009"). It'll only get worse over time, of course, but an H5 case is a piece of crap that should never have been used in the first place so you aren't risking much. --- Eric Larson <[EMAIL PROTECTED]> wrote: > Now I confused.
