I removed the lower unit along with the top unit, removed the gear, replaced the gear, then put back together. I removed the grease, saved most of it, then discarded what looked like the dirty grease. I cleaned inside thoroughly in case broken parts were inside. The three schematics were very helpful in re-installed. Mixer was 40 years old but works like new!
