If you are going to change the Clutch too, just drop it down. Your Bell Housing can stay and is designed to change the Clutch and Pressure Plate with it in place. There is a Cover that is supposed to be on there as you have mentioned.

Yep When I changed the TO bearing on my 65 C-50, I cut a short piece out of a huge log to support the transmission when I slid it back. You only need to get the input shaft far enough back to slip the bearing off the end (still inside the bell housing IIRC). Nice thing on the big trucks is that you can sit up underneath the cab between the frame rails

Be aware though - if the TO bearing is squealing then you might have some damage to the fork already

Mine had a grease zerk on the TO bearing - which of course I didn't discover until I had to replace it
