1972 CT2 175 Yamaha Clutch #1
I need some help i cant for the life of me remember how the clutch goes back together. I looked at the diagrams on parts break down and looks like im doing something wrong. I have 2 washers and a bearing washer but on the diagram it only shows a washer and bearing washer. It looks like it goes this way

But not positive

If you order the parts, the bearing comes with one washer and then there is a second washer so two washers, one bearing.

Make sure the gears are pretty well aligned (basket gear doesn't look like it's in or out too far with respect to crank gear.)

After tightening hub and before installing plates, inner hub and outer basket should rotate freely and independently... trans in neutral... if crank gear is in place obviously you won't be able to spin the outer basket but should be able to twist outer basket a little and feel the gear backlash as well as have some up and down freeplay in the basket.

I'm stuck on the rear thrust washer (behind the basket collar but in front of the bearing). The service manual cross section diagram shows two thrust washers there and the parts diagram shows only one. I've bought a couple of these washers on ebay (no longer available from yamaha) and both are different in ID, OD and thickness. The clutch on the barn find I'm working on is rigged so I cannot trust what was done there. Can anyone confirm how many rear thrust washers should be there and can you give me the ID, OD and thickness?

One thick washer goes on first, sleeve fits inside it. Then install basket over sleeve making sure that washer doesn't slip down.

If you order a new bearing, it comes with one washer (parts diagram doesn't show that). That washer goes on first... from memory, it's the thinnest, then bearing... It's been a while, but I think the last washer to go on (right after the bearing) has the same OD as the bearing but the ID is too small to fit over the sleeve.

Hope I got that right and it makes sense!

Example of how bearing comes with one washer can be found on ebay.

Yes ,a bit of a skew ball that one. Had me fooled as well for a few minutes but that was because i had three new bits in hand and two came off. That's why i'm waiting for a second new clutch assembly coming from the states. The Previous owner has destroyed the clutch basket on my CT3. There's a large trench embedded into the outer basket inner face.

It's as you have it in the pics up the page. Bearing comes with a reasonably thin washer for the bearing to run against otherwise the needles are running on a cast center of the basket which is no good. Sits on the step of the center sleeve, call it spacer, & thick washer sits up to the spacer giving running clearance for the bearing--in theory!!. Unless things have been overtightened or something over te years & it'll then lock the center from free wheeling. So when the center nut is fully tightened, make sure you can spin the center by hand easily.

Sorry for causing the washer confusion (and hi-jacking osageorange's thread). I was asking about the large washer that goes on first (not the washers next to the bearing). The consensus among ebay sellers is that the large (1st on) washer is 31mm (OD), 20mm (ID) and 3mm (thickness). I going to guess that the Yamaha service manual cross section diagram is indicating that you can put more than one washer first as an adjustment but only one is required. Thank you to all who offered their advice and help.
