Following the manual, (page 7A-18) I removed the reverse gear and it's shaft.
Notice the white plastic washer on the reverse gear shaft....
I then removed the 5th and Reverse Gear Shift Shafts as per the manual.
It took a bit of twisting and gently pulling to get them out as one unit.
So far, the only thing that won't come out easily is the sleeve on the
input shaft end in the photo above.
I removed the two shafts all together by tapping on the Input shaft inside the Bell
with a rubber mallot and they popped out.
