Toshiba 6LJ76810000 Gear 10S40-10S31 Main Drive for e-Studio Copiers

Main Drive Gear for e-Studio Mono Copiers

The Toshiba 6LJ76810000 gear is the GEAR-10S40-10S31 drive component used in the main drive unit of Toshiba e-Studio mono copiers. It meshes with the mating pinion on the drive shaft and transfers motor torque into the process assembly. Toshiba lists the part for the 2006, 2306, 2506, 2007, 2307 and 2507 chassis.

The gear carries Toshiba’s 10S40-10S31 designation, which identifies the tooth profile and shaft interface used in this drive train. It seats on the drive shaft inside the main reducer housing. Two gear faces run against the adjacent pinion, so the moulded teeth carry continuous load through every copy cycle.

Fit the part during main drive service or when the original shows chipped or polished teeth. Remove the drive unit cover, release the retaining clip and slide the gear off its shaft. Check the mating gear for matching wear before reassembly. The part also fits e-Studio 2303A, 2309A, 2809A, 2303AM, 2803AM, 2505, 2505F, 2505H and 2802A/AM/AF models.
