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.
