Hubs, Gearboxes and SprocketsCan't find 'em, grind em - hubs and transmissions, problems and modifications to make your motorized bicycle run smooth and trouble free
Does anyone know how to assemble this hub SG-7R40 from the DRIVE side or is there a drawing of the DRIVE side assembly
I can only find the nondrive side info at Shimano
Because you have an unusual need, and have received no replies, I will reluctantly recommend another forum. There is an internal hub forum on the mtbr.com forums. They can help with internal hub issues. However, there are a lot of rude people on that site.
(especially if you mention that you have a motorized bike.) You may have to endure a bit of abuse before receiving useful help. Godspeed.

Thank you for the info goods info there.
I contacted Shimano a few times and spoke with a few different techs. The last tech was very good and offered me a replacement from their discontinued stock if I could pick it up. Luckily I live only 10 miles away. Thanks again
