1. Remove transmission case while slightly tilting it to prevent 5th
shift fork from interfering with case.
SMT188A
2. Draw out reverse idler spacer and fork shaft, then remove 5th
and 3rd & 4th shift forks.
+Be careful not to lose shifter cap.
SMT082A
3. Remove control bracket with 1st & 2nd shift fork.
+Be careful not to lose shifter cap.
SMT577
4. Remove gear components from clutch housing.
a. Remove three screws and detach bearing retainer.
+One of these three screws is torx type and should be
removed with a suitable tool, as shown.
SMT579
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.
