This lil lock washer is the reason why i had to split the cases like 3 times.. I gave up and saved it for another day.. Well today i figured it out.. Got some pics to show.. First pic is of the two washers that interlock.. Second pic is the first washer that goes on. Fits nicely on the grooves.. Third pic is the washer with the teeth that lock into the first washer. You can see the gap in between the two.. After a lil while of tryna figure why it wont lock in there.. I spin the spline in my hand and the washer spins and aligns to where the second washer will let the teeth lock in.. Just that little gap would not allow the gears to shift correctly... Wheeeew!!

I feel your pain! Glad you got it solved now though!

I have to take note for when I rebuild my bottoms
-
Yea man this lock washer is a tricky one. I sure know these R bottom ends alot better after this past weeknd. Having to assemble then dis assemble over and over i found some ways to do stuff easier. The tech manual is so outdated and all over the place with steps.. Any questions just let me know.

That is a simple mistake, any one of us could make, so dont go beating your self up over it.
One thing I can tell you, you just graduated from the University of hard knocks in transmissions, because you are one that has learned from a hands on mistake & nobody can discredit or take that away from you, you'll never forget that.
Now just think, I'm 62 & just about 99% of what I know about engines, I got from that same University of hard knocks & no one can discredit or take it away from me.

If I completely disassemble my transmission I always make sure I get the 250R microfiche out and separate the main shaft components from the countershaft. Then use the microfiche to re-assemble.
Can't tell you how many times i've assembled a bottom end and it won't shift. Happens to the best of us

thanks neil thats pretty cool of you to say. somebody that has as much respect in the 250r world as you do giving compliments. i sure did learn alot. but now im stuck with the issue of i put it all together assembled into the left crankcase and then put in the crank which went on pretty nice. then i put the right case halve on and i have to beat it in with a hammer and a wooden block. thats the only way i can get it in. the tranny moves when i do that so it wont shift once i get the halves together finally. rsss396 told me i need to sand down the inside of one of the bearings just enough to make it a slip fit. i was thinking can i do this with also a combo of crank in the freezer and a lil heat on the inside race of the bearings?? what do you guys do to pull the halves together and everything work like it should??

I found a 3/8 washer part blocking an intake passage on a YFZ I used to have, That washer is now a key chain!

I have a crank puller. if I was closer to you I would let you use it
-
props dude!
I dig how you guys post so many more pics these days than the last 5 R sites over the yrs, way helpful!

now im stuck with the issue of i put it all together assembled into the left crankcase and then put in the crank which went on pretty nice. then i put the right case halve on and i have to beat it in with a hammer and a wooden block
Is it a hot rod crank? The OEM crank is a slip fit, the right case half should slide on fairly easily. The hot rod crank is a press fit on both sides, on my hot rod +4 stroker I sanded the right journal down with emory cloth to OEM diameter to make it a slip fit.

If everything is right, you shouldnt have to hammer on the cases to get he bottom end back together.
That is the only thing about the Hot Rods crank, not being a slip fits in the clutch side main bearing.
Now I do different from you, I put all the transmission stuff in the right hand case half, everything, then I have the main bearing that is slip fit. Once that is complete, I heat the main bearing on the left hand case half & slip the crank in, let it all cool, then its just a mater of laying the center gasket in place with a little thin coat of three bond for insurance around the outside of the crank & then slip that left hand case half onto the right hand.
Sometimes I may have to bump the case half with my hands, to get it to seat all the way together, but never have to beat them together.

Yea it's Gona be a hot rods crank and new Oem 8ball bearings.. All this is great info. I will try your method Neil and also the Emory cloth.. Thanks guys

Ok, now when you get to the front shift fork, you'll have to play with the main shaft just a little to get the fork pin in the shift drum groove & behind the center of the case, but you'll figure it out & after it will be easy.
It is a lot easier for the shift drum, to slide into that needle pin bearing in the left case, than it is for the drum to fit into the ball bearing on the right side case.

Ok ill let ya know how it goes when i give it a try. May not be tonight but most likely tomorrow

that lock washer confused the crap out of me then I figured it out by accident!

Yeah that can happen, cause you have to look real close at the pic, to see the groove in the shaft, so that the flat washer can rotate just a bit & then the locking type washer lips slip into that flat washer.
Sometimes something that can confuse us, if your looking at a micro fisch exploded view, how the parts go together not always right & may have a part out of place to catch somebody copying the OEM fisch.
Rand Macnally road atlas is the same way, towns in the wrong place & towns missing to catch a company copying theirs.
