Good Key, not quite the right size May 24, 2016 Reviewer: William Walter from Lowell, MA United States   We used this key with the PG71 gear motor and the 16 Tooth Gear (am-2088). The key is the right width, but it really wants to be 4mm x 5mm from what I could tell. The key did not fit tight and would loosen up with use. We ended up needing to use a shaft collar to keep the key from falling out. Even then the interface would get sloppy with use. Was this review helpful to you?
