b. Remove input shaft together with mainshaft by tapping lightly.
+Always withdraw mainshaft straight out. Failure to do so
can damage resin oil channel on clutch housing side.
+Do not draw out reverse idler shaft from clutch housing
because these fittings will be loose.
+When removing input shaft, be careful not to scratch oil
seal lip with shaft spline.
