If you did not remove the intermediate gear and main-shaft, then simply push the lock-plate down into position, reinstall the drum support (after greasing the bushing) and you’re done with the lower end.
If you DID remove your intermediate gear and main-shaft I can post pics of how to reinstall it along with the bronze bushing and seal.
I have pics of the the upper housing, motor and clutch reassembly ready, but I’m too tired to post it all tonight. So be patient…and I’ll get them done soon.
