This post is related to my other post on what gearbox bearings to buy, but I figured I'd best post this as a separate question  as that post is a little older now and was assuming I had a 4 synchro gearbox.

 

I have an A+ engine and (i think) a 4 synchro gearbox, but Im a little confused as I have this gear here that looks like the 2A3709 (1st motion roller for 3 synchro) and also I only count 3 synchros on my partially disassembled main gear set. Basically now Im confused if my gearbox is 3 synchro or 4. I definitely have the 3 step layshaft so it should be the 4 synchro type but this gear here is just confusing me. The 3 synchro roller is extremely expensive and I want to be absolutely sure before i buy it.

 

here are the pics. maybe someone can recognise what bearing this is.

 

Note the big nut on the first pic.

hmm i think you're right. that would be the single roller bearing. phew.

 

one last question. in the minispares gearbox rebuild kit there are a set of 7 bearings. don't recognise one of them do you happen to know which one it is?

looks like an A+ 4 syncro first motion shaft with the first motion shaft transfer gear still attached.

 

good luck getting the nut off to - normally it would be undone with the main gear shaft locked in place

i know, thats how i would have done it too, but while i stepped away for a break, my mini guy's assistants decided to continue stripping the gearbox without me and when i came back they had taken most of it apart and that nut was still in place...

 

im thinking towels and a bench vice to hold the gear in place, and a really long breaker bar...
