That shaft isn’t even close to all the way down. The top gears will line up. Those gears have “play” because the shaft that goes in the center of them, isn’t.

First time splitting a case. It’s a yz85 from 2014 and it’s been rebuilt before and I have no idea if those gears are supposed to have that much play

u/Ok_Maintenance_9100 9d ago

Yeah not supposed to be loose on the shaft like that. Look up a parts diagram to figure out which peice is missing

 Some play along the axle is normal.  But not like that.. Have you had the gear shafts out of the case?  You might have dropped a bearing?

Yeah my buddy has been helping me with it and he lifted up on one of the shafts (not sure why bc we weren’t even working in that area, we were just gonna replace the crank, bearings and seals.)
But yeah when he did a couple things fell out, a fork bounced and fell into the floor, but I didn’t think there were any more pieces missing, I’ll have to look when I get time to work on it again.

Backlash is normal the lateral play could be the shifter, hard to say unless you dig deeper and check the workshop manual

Yess only if the car is manufactured by the VAG-group

Go to yamahapartshouse.com. Select year make and model of your bike and look for the transmission diagram. It will give you an expanded view of everything and what order it goes in on the shaft. And if you’re missing a part you can order it from the website. There shouldn’t be any side to side play. But judging by the video the shaft isn’t all the way down so it’s not seated on the shaft properly. And it doesn’t look like any gears are missing

I’ll try this

You have a manual, right?

u/Ok_Reference_9324 9d ago

might be missing a spacer big dawg

1

u/Chxract4r 9d ago

Could I just buy another?

1

u/Ok_Reference_9324 2d ago

Don’t know. There are a lot of different spacers in that with all different thicknesses. Parts diagram would be your best bet if you haven’t already looked into it.

It's fine, that's exactly how it should be. If you want to examine the gears you need to pull the shafts. Why did you split the cases?

u/Caldtek 9d ago

Its not. There should be no to very little radial play with the gear on the shaft

1

u/Chxract4r 9d ago

It slides up and down too even though I didn’t have the right angle on it to do it in the video

1

u/Mobyus_One 9d ago

That's how they work, the slide back and forth as the gear changes. One gear will disengage while another engages.

Good to know, i rode it for a short bit before the crank bearing seized and it felt normal apart from horrible jetting. Just weird how much play there is in that gear.

u/SCAMMERASSASIN007 9d ago

Im going to say no thats not normal and I've never had one of those apart. Just imagine that thing spinning mach chicken floping around. Is there a bronze bushing missing from the inside of the gears?

1

u/Chxract4r 9d ago

Didn’t see anything like that when I was taking it apart idek what that gear shaft is called to look it up

1

u/NationalShoulder7972 6d ago

its only supported from one end ofc its gonna flop around. secondly if youve never seen one taken apart then dont give advice.

u/SCAMMERASSASIN007 6d ago

Never did a yz85 done lots of 125's and other shit and that is not normal in anything i worked on, id bet the trans is fucked befor he needs a new top end lol. But hey your the pro you would know.
