Yeah, each shaft and what was on it was stored in separate containers. The order in the haynes manual just threw me.

The counter shaft in my haynes manual and the parts list https://www.dropbox.com/scl/fi/geanqsh7vy2m8ewyqncnl/400-4%20Part%20List%201975%20searcheable.pdf?rlkey=hqb1np807bko695nym500d9zo&e=7&dl=0 seem to be slightly different. The haynes manual shows part 250 being a circlip and not the washer.
It was the wrong gear, the haynes manual had a wider gear, putting the one listed in the parts list was a little thinner and allowed the washer to rotate into the grove and then washer with the bent splines slots in. Weird. The haynes manual I'm using is CB400 and Cb550 fours. 3

Got it! The haynes manual parts diagram is wrong. It must be the 350f. Its showing the wrong gears. Looking at the parts list its 33t then 30t, the haynes manual shows 30t first that's why it wouldn't fit. Sorted!

This is the only way they sit flush as far as a I can tell.

Hmm, so the washer washer with the bent splines then the flash washer?
In the parts list it shows as the flat washer in between the gear and washer with the bent splines. There is no way the bent splines fit under the flash washer even trying to fit them together not on the shaft doesn't work. Edit, reading through my haynes manual again, it does mention that the splines go inwards into the washer but I don't see how it fits. I think the diagram is also wrong. Its not showing the correct washers or gears. https://www.dropbox.com/scl/fi/geanqsh7vy2m8ewyqncnl/400-4%20Part%20List%201975%20searcheable.pdf?rlkey=hqb1np807bko695nym500d9zo&e=7&dl=0 7

Unless it is meant to fit with the bent splines facing away. Like this:

Im rebuilding the transmission and cant quite figure out who the 25mm lock washer goes on. Its part 90462-323-000 and seen here on yamiya https://www.yamiya750.com/index.php?main_page=product_info&cPath=179_273_206_210&products_id=2860.
Is it meant to sit flush with the thrust washer? The outward splines wont fit underneath the splines on the thrust washer. I just want to double check that it seems correct before I put it all together. I didn't do the rule of you never have enough pictures... 9

The gearbox on Ratty had over 45k on it (probably over 50k as the PO had fitted a mini Speedo on the bike at some point). When I checked the roller bearings they were fine, no play, no nasty rumbling and no tight spots. The rest of the engine was in a terrible condition as a result of the PO blasting it with a sand gun. The roller bearing was good to go again but unfortunately the shaft was worn beyond repair and I purchased the two gear shafts from Ted. I have no idea how many miles were on that gearbox but again the roller bearings were absolutely fine. The bearing doesn't feel great, quite gritty when spinning it. 10

I've tried heating the collar, clamping the bearing and giving the shaft a wack. Not budging at all.
There does seem to be a seal between the bearing and collar. There is no way to remove the gear, the groves are too big for it to slide off the other way, the bearing and collar are holding it on. 11

The shop manual doesnt show a seal between the collar and bearing/bearing and sprocket.

Ill have to dig my vice out from the garage. I didn't think of clamping the bearing. I didn't want to damage it too much but I think that's the only way. 13
CB350/400 / Re: Transmission output shaft bearing removal« on: May 26, 2024, 06:34:50 PM »How to remove the output bearing. I've added the picture, it didn't work at first. I don't think the bearing first over the collar? The collar seems to be bigger than the bearing. Its the collar that I cant seem to remove. I've not tried heating it up yet, I'm going to try later. 14

More bearing headache. I managed to get one of the 5205hs bearings off easily but the other one has a spacer type thing that closes of the hole where the output sprocket it. because its been exposed and dirty and wont budge. I cant get my bearing puller behind the bearing and I don't want to risk trying to pull the bearing and spacer off by the gear sprocket. Has any had any luck removing it?
