Pin #30 is for alignment only and it does not wear.

Will the transmission shift using a socket on a T-handle to turn the shift drum? And I presume you know it will not shift without one of the transmission shafts turning? When the engine is running, the input shaft is turning with the crankshaft. If the engine is not running, the countershaft must be turned to facilitate gear change. Sounds to me like there is nothing wrong and you just don't understand the physics of the transmission.

It should not turn freely all the way around - it should turn a bit then the rear wheels need to be turned so the engagement dogs align and it will then click into gear and the lock (arm with roller on it) will hold the drum in that position, you can then turn again, sometimes just clicks in and sometimes kind of hangs, rotate the wheels back or forward and while turning the drum, it should align and click into the next gear. It's easy to show and hard to describe.

Can I add videos on here
So it locks up the bearing when you tighten the center bolt?

No you can't post vids directly - you have to upload a vid to VIMEO or YOUTUBE and then post a link to the video

If it's locking the bearing, then I have no clue as to what's happening - did you have the parts off the other end off the shift drum?

That might the problem, but not because it's worn out - it just takes a nub to position the star to the drum - if you could line them up and tighten the center bolt without the parts getting out of line, you wouldn't need the pin - work on getting the two parts together with the pin in the notch, remove the shift lock, rotate the drum as far clockwise as it will go (I am not sure if that will be high or low gear) and you can tighten the bolt using a torque wrench - if things are lined up right, you will be able to rotate the drum counterclockwise with a pair of snap ring pliers inside the star - when it is turning freely, then assemble the shifter flapper and install the shift shaft.

Manual says tighten securely but did not know if it has a torque spec
Sorry - I had to quit early last night and just got back on line - I don't and won't have a smart phone.

Yes, the shift lock is the arm with the roller #21

Torque on the star retainer bolt is #17 is 17 ft lbs (I torque them to 18 ft lbs as + or - 2 ft lbs is the margin of error of most torque wrenches)and the thread locking agent is specified as medium (Loctite blue) - note don't Loctite the bolt until you know it's working and are ready for the final assembly.
