Nissan Micra Manual Transmission Clutch Housing Oil Seal & Bearing Repair MT-9
Service manual page MT-9 detailing clutch housing and transmission case oil seal and bearing repair with illustrations.
This is a single page from a factory service manual section titled 'Repair for Component Parts – Clutch Housing and Transmission Case' (page MT-9 of the Manual Transaxle/Transmission section). It illustrates seal and bearing service procedures for the clutch housing and transmission case. Covered procedures include: removal and installation of the input shaft oil seal (removed by hand/tool, installed using a drift and hammer – figures SMT939 and SMT940); removal and installation of the clutch control shaft oil seal (pried out, then driven in with a drift – figures SMT941 and SMT942); and replacement of the input shaft rear bearing, which requires removing the welch plug from the transmission case with a pin punch and hammer (figure SMT899). The text instructs the mechanic to apply sealant to the welch plug, install it on the transmission case, and then press-fit the new bearing using a special tool (figure SMT900). One photograph shows the location of the bearing inside the transmission case. The page contains no torque values, part numbers, or year/model designations; instructions are conveyed mostly through labeled line drawings.
