Disassembling TR3 Tranny-questions

Hi all,
Since I have a little time on my hands I decided to take the transmission 
course at our local Tech school and use this as an opportunity to learn how 
to rebuild my TR trannies. I have 2 TR3 trannies that I intend to make 1 
good one out of.  Each has its own set of problems.

I'm following the Bentley manual and even before I really get to the 
interior of them, 2 problems have come up.  Can this be a foreteller of 
things to come?  Ah, the learning experience.  Anyway, back to these 2 
problems.

First is with the through out shaft.  The instructions on removing this are 
simple enough..remove the wire securing the bolt that holds the clutch 
operating fork arm to the shaft and remove the bolt. Done...no problem. 
Remove the grease fitting and bolt on the side opposite the clutch slave 
cylinder side and then slide the shaft out.  Well, it does not slide out 
and my original thought was the build up on the shaft from years of 
accumulation.  The  fork itself is not sliding of the shaft, even with some 
coaxing with a hammer.  Nor will it rotate around the shaft.  I've tried 
this on both trannies and they both  have the same problem. So I think I 
may be missing something.  Anyone share some ideas on this problem?

Second is with the removal of the speedo gear.  Again I've followed the 
instruction in the Bentley and removed the retaining bolt but the gear does 
not want to come out.  Is the gear itself screwed in?  There are flats on 
the side of the shaft protruding from the gear  box below the threads for 
the speedo cable.

Any help greatly appreciated.

Doug
