Hello.....Got a Honda BF15A from early 2000's (i think).....anyway, Its a junk engine, but Im rebuilding it as a school project just to see if it can be done.....Got it completely disassembled except for the 2 bearings that the counterweights attach to. Looks like they are just press fit into the cover, and have no access to the back of them to drive them out. is there a special tool or something. I dont care if I damage them (as long as I dont damage the cover they seat in), they will be replaced upon rebuild anyway....Any ideas? Thanks.
