Pololu 120:1 Plastic Gearmotor Diagram?

I am trying to find the exact size specifications for the Pololu 120:1 Plastic Gearmotor 90-Degree Output (https://www.pololu.com/catalog/product/1121).

The application I need it for does not have a very big clearance, so I want to make sure it will work for me. Specifically I really need to know the dimensions not including the output shaft and the length of the shaft itself. This other gear motor I was looking (https://www.pololu.com/catalog/product/1124) at has a great diagram in the product description. That is all I would need… and I think they are both Popolu gear motors. I would think there would be one for the one I’m looking at floating around somewhere.


We are working on dimension diagrams for our other plastic gearmotors and should have something in the next few days. I’ll post here when they’re ready.

A dimension diagram for plastic gearmotors #1120 and #1121 (pololu.com/catalog/product/1121) is now available under the resources tab of the product page. We’re still working on a diagram for the offset-shaft versions (#1122 and #1123).
