Thanks. It was correct… but the old one appears to be wrong, but it worked which is odd. Doesn’t matter as that’s going in the bin.

So, I’m in the box. As I’ve mentioned, the Layshaft was new… however your question here is ringing in my ears.. I have managed to remove the bearing from the end of the Layshaft as I was hoping to use it on another and switch it out. I then dug out the original layshaft and the bearing it still on it… but it’s on the other way around…. So, how do I know which way is correct? ( obviously hoping it was the wrong way around as it might help fix it) any reference anywhere?

Also, I’m thinking I should use a new bearing.. but this one was about £60 from synchrogearboxes. The britpart one is about £11. Anyone used it without issues?

Ive used all britpart bearings on the last build. (used the syncro ones at first but they got trashed with bits of broken gears )Never noticed any noise difference and have been running for at least a year with several reasonably long journeys, time will tell!

I generally choose anything Swedish or Japanese.

Evening! Thought I’d report back to close this off. It’s done, and works! No crunches up or down the gears, hi and low all good, 4x4 good, overdrive works great… no odd noises… so pleased..

I ended up changing a few things at once, which isn’t normally the way as you never know what change solved it, but I wasn’t going to keep removing the box to each change.

I replaced the 3/4 synchro hub for a genuine new one.. (remortgaged for that), replaced the alleged genuine layshaft with a proper genuine new one, the difference visually was interesting, with the reverse teeth rounded to receive the idler… and whilst in there, popped the original synchro rings back in as they were in fact still in good condition and well within tolerance. I replaced the Layshaft bearing & race and ensured correct clearance, using a smaller spacer.

I have ended up with a very expensive rebuilt gearbox. Everything, I mean everything is nos genuine parts, other than the baulk rings… ironically. But, it’s perfect now!

Hope it’s useful to someone. If anyone needs any suffix A gearbox parts, I might have a good serviceable one of what you need in the box of what’s left, just ask!

Well done so pleased for you getting it sorted, perseverance paid off, that should last a long long time
A lesson for all to use genuine parts particularly in gearbox
