Shaft adaptation issues
This is a very strong motor gearbox combination, but is difficult to connect to the non metric world. The PG Shaft to 1/2" with 1/8" Machine Key Adapter (am-0996) is a very poor way to do this. I tried the suggested assembly technique and had no success. I needed to file the metric side key of the brass part to make it fit at all. Both adapters eventially slid off the shafts when in use in a vertical application on our airship rotors.

"Specs error"
"I may be wrong, but I think the rpm's and gear ratio are mixed up, It should be 188 rpm's and 28:1 gear ratio. Great motor otherwise."
