what's up everyone hope you guys had a great Christmas and were able to spend
some time with your families I know I definitely had a good time so what I've
got here behind me is an O three cr250 engine and it is not wanting to shift so
I'm gonna bust it all the way apart and figure out what's going on with it I
know I look like Red Nosed Reindeer right now it is freaking cold in here
but nonetheless I'm excited to bust this motor apart let's get going all right
I'm gonna show you what's going on with this thing I'm gonna pop the shifter
onto the shaft so going up is completely locked solid doesn't really matter if I
turn over the engine or the counter shaft it's still locked solid and then
going down is not really do much either so hoping it's something simple but
we'll figure that out soon so this cylinder is just chilling on here it's
not bolted down at all I'm gonna pull that off and then move on to pulling off
the flywheel and stator
now I'm gonna transition over to the clutch side and as you can see there's a
lot of missing bolts on these covers so I'd venture to say it there's probably
some missing parts inside too
bummer deal I've got a broken outer clutch cover so this is another part I'm
gonna have to replace so the first thing you notice the plates are gone that
pressure plates missing and on this inner hub one of the studs for the
pressure plate this one right here is busted off so this inner hub is junked
too
well here lies the problem guys on the shift shaft this is the one that goes
through the cases and the shifter bolts on on the other side so this hole right
here is supposed to go over that pin so
that's an easy fix I could probably just do it right now just like that so it
should be working fine now let's test it all right I've got the shifter mounted
up and I'm gonna test the shifting assembly so I'm gonna pull up see what
it does
so that's clicking it into gear and then going down and it always helps if you're
spinning the transmission when you're shifting this helps it pop into the
gears a little easier so I'm gonna find neutral go all the way down and halfway
up should be right there and how to test if it's in neutral
I'm gonna spin this main shaft and then the counter shaft won't stand they'll
spin independent of each other and so I can turn them against each other and
they're not locked but then if I go down into first gear so now I'm in first gear
they're locked against each other one will not spin without the other spinning
and then it's the same through all the other gears so it's in first gear now
I'm gonna pop it in a second
we got third fourth and fifth so it looks like everything's good to go with
shifting and transmission all right I'm gonna finish tearing this thing all the
way down since I'll be replacing the crank crank bearings and seals and all
the gaskets
but there's something inside that I need you to release which way is right which
way is home
so this is how I'm organizing all the bolts and smaller parts on the engine so
far I've got ziplock bags labeled clutch and shift so all the shift components
all the little bolts and springs are in here and then I've got all the clutch
parts in this bag now it is on to split in the cases I've got some bolts on this
side of the engine to pull out and then I can split this thing into
you know what I'm gonna try splitting the cases from the left side I've always
preferred going from the right but I've seen a few people split from the left
and I'm gonna give it a shot see how I like it
you give on the mall and I can return
brothers are so much
I'm actually really surprised with the condition of this bottom end didn't
really come across much it was messed up transmissions in really good shape along
with the shifting components cases are actually super nice although a bit dirty
so that's a huge plus and the only things I'll really need replacement or
the cylinder I got to do something with it either a replay tree sleeve or just
buy a new cylinder gotta buy a new hub it's got a broken stud and while I have
the engine apart I'm gonna toss in a new crank - I tell you what guys I am really
stoked for the next video I'll be cleaning up the subframe the swing arm
and the frame gonna be getting these things as close to new as I possibly can
and I gotta clean the frame outside in 20 degree weather that's gonna be fun
but this is gonna be a mind-blowing video so keep your eyes peeled thanks
for watching everyone if you enjoyed the video give it a big thumbs up and write
me a comment down below I'll check in with you soon see ya
Oh
