Hi all, I'm at the end of my rod change box rebuild, ready to torque down the pinion gear and am beginning to worry as the gears are not spinning at all. They spin maybe 1cm in either direction without resistance before stopping as if they're up against something. They're the same with or without the layshaft installed. I don't want to torque up the box for fear that I'll crunch something / whatever is stopping them from moving - is this illogical? As I know this can help to seat the gears... Should I just pull the main shaft out again? It's in neutral, no gears engaged. Any advice welcomed, this is the first time I've done anything like this!

can you spin 1-3 on their own individually?

It'll most likely be binding up on the Baulk Rings. Torque up the 1st Motion Shaft and Mainshaft Nuts. That pulls these shafts away from each other and lets the Baulk Rings float and not bind.

I've just tried to move them individually and they're not moving at all - also just realised that when I engage reverse it locks up entirely, and I can only get the selector over to 4th, no 3rd 2nd or 1st
I've been very slow going on this project as it's dragged out over my pregnancy and then having such little time with an 8 month old... Could it just be that it's seized slightly..?
Any ideas how to either free up the selectors (provided that isn't the cause of the issue perhaps?) or to engage the gears differently in order to be able to torque the nuts ?!

I'm not surprised.

Check the Interlock Spool is disengaged completely and with it rotated about 180⁰ from it's normal position, pull it as far out of the gearbox as it will come, that should stop it fouling on the bellcrank forks, something like this;-

 

 

Then use a soft drift and knock the Syncho Hubs over to engage 1st and 4th gears. That will lock it up so you can Torque up the Nuts.
