Nissan Micra Mainshaft & Diff Side Bearing Preload Adjustment - MT-21

This is page MT-21 from a Nissan manual transmission service manual section covering mainshaft and differential side bearing preload adjustment. The page presents steps 7 through 9 of the procedure. Step 7 instructs the technician to position the transmission case above the dowel pins and collars and to set the collars in the positions shown in the accompanying figure, which includes a torque specification of 20 N·m (2 kg-m, 14 ft-lb). Step 8 explains that a feeler gauge is used to measure clearances between mainshaft adjusters (A) and (B) and between differential side bearing adjusters (A) and (B); two photographs illustrate this measurement, labeled 'Mainshaft side' and 'Final drive side'. Step 9 directs the reader to determine the total thickness of shims to be used at the adjusters, using the S.D.S. (Service Data and Specifications) table as a guide. From this page, a reader can learn the intermediate steps of setting bearing preload during transaxle assembly: positioning the case, taking feeler-gauge clearance measurements at both the mainshaft and final drive/differential adjusters, and using those measurements with the S.D.S. table to select shim thickness. The page carries no explicit year or model identification.
