Shimano Nexus 3 Gang Nabenschaltung Wartung & reparieren - zerlegen reinigen schmieren zusammenbauen

Detailed instructions on how to open, remove, disassemble, clean, relubricate (oil and grease), and then reassemble, reinstall, and adjust a Shimano Nexus 3-speed internal gear hub with a coaster brake. This guide shows the entire process of overhauling and repairing this hub, including all important details. Such a complete overhaul is necessary if the hub is noisy, stiff, slipping, or no longer functioning properly. It can be performed for maintenance and servicing, or to repair a defect and replace parts. These instructions apply to the SG-3C40 and SG-3C41 models of the Nexus 3-speed hub with a coaster brake—but not to the early Nexus 3CC 3-speed hubs with the shift pin on the left side. Models with a roller brake or disc brake are constructed differently and are described in a separate guide. Spare parts for model SG-3C40 (older) https://si.shimano.com/de/pdfs/ev/SG-...
