After a gearbox rebullid wont select 1,2,3,4 gears.

So i just closed a jc5 130 gearbox to it i fitted new syncros, new bearings, New springs and balls, everything was in fine and was shifting properly now i cant engage nothing but reverse and fifth.

Anyone has been in the same boat?

I Had a similar problem with e rebuilt box where it was stuck in two gears. I Was told this was due to the reverse idler dropping during shipping when i received it so i'm doubtful this is your issue but maybe something to consider

Time to open it back up.

I've had one do this to me before. Take the end cover off and upload a pic. I need to be able to see the selector shafts.

Cant upload right now but i’ll tell you, fifth in “neutral” (up) reverse in neutral (up) both 1&2 and 3&4 in the middle and will move a bit either up and down but wont engage The ball in The notch

Well the one I had mate, had to be opened back up again. I found nothing wrong with it internally, put the lid back on and it selected all gears perfectly fine.

So it might be a case of a little misadjustment and just needs a “reset”?

More a case of it's a Jc5 and one of its many 'quirks'. f**king things.

Took it to a shop to get it “giagnosed” after i rebuilt it, shop man called telling “The second gear syncro must have been pressed wrong and it is broken so the whole secondary shaft is frozen solid, seized”

Is this even possible? The gears rotated so smooth and the rings moved up and down like butter when i got it pressed


Edit: previously i could select ALL gears but box would crash reverse and seize selector, missed the little pin first time, rebuilt it and then the start of this thread

Well you can press the synchro rings on too much yes, but I strongly doubt that's your problem mate.
