Went into my ASA Mitsubishi program and found the bushing that the manual doesn't show. I have seen this part in the box of stuff I got back from shop but 1st time I tried it seemed too small to slide onto shaft end. This will also be the same part that makes the seal also.
This is the bushing circled in red and the gear is shown too. Glad I have this ASA software, it shows what many manuals just don't.
