3rd/4th gear shaft disassembly

I was about to re-assemble my transmission now that I've finished cleaning everything up and I've rec'd all my parts. Although the 3rd/4th gear train looks fine, I want to flip the syncros and check the slider. I've been putting this off and considered just putting it back together without disassembling the 3rd/4th gear assy. I wasn't sure how to get the nut off the assy anyway, but I finally found an easy way to get the nut off - I held the nut in my bench vise and found that a 22mm socket fit snugly around the spline shaft at the other end. Turned off easily (see pic below).

Now that I have the nut off, the same technique I used to remove the 1st/2nd gear assy from the shaft does not seem to work with the 3rd/4th gears. With the 1st/2nd gear assy, I protected the shaft end of the gear train with a rag then wacked the shaft end onto my concrete floor - the gears slid off quite easily. This technique is not working with the 3rd/4th gear assy. I'm trying to remove them off the end the nut was removed. Before I try more force, is there a better way?

Thanks.

Geoff

Casings nice and clean:

Disregard - I protected the shaft end a little better and gave it a major drop everything loosened up. A couple more drops and everything came off.

That is a brilliant idea for removing and installing that nut. Do you think you have any problem with marring the splines?

I think the splines are pretty hard. I didn't see any marring, and the mating parts slipped on fine. It just happens that the 22mm socket fits on pretty nicely.

O.K, I play:

Special tool made from a clutch disk and parts of MikeZ's old bed frame

My way is to hold the entire shaft by its large nut in the vice and use the tool to apply torque for loosening/tightening. It's not possible to measure torque but it you use the old mark on the nut flange as reference and go past it a little bit when tightenign so it's in the ballpark.
