The rebirth of Lazarus
Oddjob:
You mean the large collar on the end of the shaft Mick? I actually removed that the other day from the countershaft I removed the gear from. Just mucking about. I removed the bearing as it's a very hard to find part, this one seemed fine, span it in a container of brake cleaner and it sounded ok so I removed it from the shaft, spotted the little O-Ring that sits behind the bearing so thought I'd remove that to. Then noticed the way the shaft was machined, which meant that the collar had to be removable, which it turned out to be. Only the very inner part contacts the seal, common to see damage on the outside of the collar. Mine has some damage.
I cleaned up the countershaft, mine also has some corrosion on it, it's marginal as to being reused. The bearing, yep that's ok, cleaned it up, filled it with silicon oil and bagged it up in a sealable plastic bag along with the O-Ring and the collar. Almost certainly got another shaft somewhere, will take a look.
When you say gears are perfect, you mean the ones I posted pics of or the ones you have, wording is confusing me.
Wonder what happened with the gearbox you've got, seems a lot of damage going on it there. I'd inspect the main shaft as well Mick, check all gears etc if a countershaft gear goes it can take the corresponding gear with it.
Make a list of everything you need and I'll trawl through my box of bits and see what I can dig up.
Good news is that I found the top hat bush, I didn't spot it hiding in the bottom of the box, there were 2 mainshafts in the and quite a few of the gears. I looks like there were 2 complete gearboxes in there at one time. Will check the other bin I keep gearbox parts in and see if there is another countershaft in there.

Hi Ken, i meant the gears look really good and will be great for me. I have investigated a bit more and the mainshaft looks good all throughout, including the needle roller when i checked it and cleaned it. The countershaft has rust pits on the end that runs in the needle roller (no 24) so might be noisy or wear quickly , and the collar where the oil seal rides is pitted also. I have checked the selector drum and forks, and the centre fork is ok as is the lh one, however the rh one nearest the clutch side does have some wear and is a little tight on the selector drum. I am wondering if that was the cause of the dogs breaking off? so parts i need are the two gears 10 and 12, a countershaft with bearings inc needle roller, a rh selector fork and the gearchange shaft.

on even closer inspection i have found some tiny chips off the mainshaft gear, 3rd/2nd so need that also if you have one. have stopped looking now!

I may have found the internal needle roller bearing new, I presume then outer casing is still fine?
It cost £5.50 and I ordered 2 so I could test them. Will let you know when it arrives, same make as the Honda one, Koyo.
Checked the other box and nothing of use. It was this box I emptied of most of the gearbox bits as they were getting on my nerves.
The other alternative is to wait for me top split my engine and we'll see what the box is like in that. I'll be fitting my NOS gearbox in it's entirety so that box will be going spare. No idea when I'll get round to breaking then engine but some time this summer I'd imagine.
The mainshaft gear 3/2nd. I presume that's the double sliding gear, if so I spotted 2 of those in the first box. Might have a decent right hand selector, 24211-323-000, will have a look. That's the only part I'm missing for a complete NOS gearbox, I keep spotting them but they are always too dear. I was thinking of going with the Italian alternative where they make new selectors which are supposed to be better than the Honda ones, should have bought them before Br-----T though.

No joy on the right hand selector fork, got 3 left ones and remember giving the last right one to Trigger a year or so ago.
