Hello, John Talley here with partzilla.com.
Today we have another really easy project to do on our 1967 Honda
CT90. Today we're going to replace the kickstarter
shaft seal, which is right here. I've already got it purchased, so it's ready
to go and it's really easy to do. I just need
to grab a couple of basic tools and then I'll walk you through how to
get this done. Heck, I don't even need my regular table to do this, it's so simple.
So I'll be right back and we'll get this thing knocked out.
Now if you're a regular viewer of our videos, then you know that I already did
the shift shaft seal, which is basically the same procedure. So it's really simple,
you don't need that many tools, and by taking care of this you're going to
eliminate the possibility of it peeing on the floor so to speak and
making a oily mess under it. Especially on these older machines, just
over time the rubber starts to get brittle, then of course
it's going to start leaking. Now the shift shaft, it was actually leaking.
This side, it was still sealed up but it's only a matter of time
before it starts leaking from this seal as well. So we're going to take a
preemptive strike and go ahead and get it replaced, that way I won't have to
worry about it. Now before we move the kickstarter
itself, let's mark that split there so it'll make
it easy to get the kickstarter back in the same
place as we take it off. Now on a lot of machines they actually
have a little dimple or a dot that's punched into the end of the shaft,
and that's your locator for the split mark for your kickstarter arm
itself. This one doesn't have that dimple, so permanent marker, piece of cake.
That'll get it back exactly where it came off. Now in this
particular model, there is just one 10 millimeter bolt
and we'll need to remove it all the way because it does more than just
squeeze that point together. There's also going to be a channel
on the end of the shaft which the threads are actually riding against.
So it has to be removed all the way before you can actually get the entire
kickstarter assembly to come off. Now if it does not immediately want to come off
the end of the shaft, what you can do is take a screwdriver-- in
this case I'm going to use a little
chisel.
Now I will guarantee you that one had never been off before. There's that
groove I'm talking about that the bolt was actually going through
or against. Now there are a couple of different ways
we can extract the seal. We can try putting a hook
in there and pulling it out. I've had the best luck usually
with pushing this next to the shaft and then prying it out. But I warn you, if
you do that technique, that metal right there is very thin and
you run the risk of possibly snapping that outer case. Especially on a unit
this old? That's going to be kind of tough to come
by. So be careful if you do it that way. A third option is to take a wood screw
and actually screw it straight in to the seal itself,
grab it with a pair of pliers, and pop it out. But we're going to go
for the way I know how to do best, and that's just using a punch,
going in next to the shaft, and then popping it out.
Now when you're doing this technique, don't drive it too far
in, otherwise you'll scar the inside of the case.
And when you do that, it's not going to seal up properly.
So it's partially broken through up top. We're going to head down
see if we get it to pop that way. There she goes.
Close, and she is out. What we're going to do next is get
some brake cleaner-contact cleaner and use this paper towel just to clean
that edge so we don't drive any of that debris
further inside. Then we're going to go get a socket that's as close as we can
get to the outside of this without going past it,
and then use that to drive it back into place.
What we're going to do before we put it on is put a little bit of grease
around the inside of the seal and then around the shaft here.
It will not take a lot of force to get this in place,
and what we're going to use in this particular instance
is just a 19 millimeter. We want it to fit to the outside but not
past the edge of the seal. And then we're just going to
lightly tap it in place.
Next, just because that kickstarter arm was fairly difficult to
get off, I don't want it to seize on there should
we ever have to do this again in another, I don't know, 40 something years. Probably
not going to happen. We still have our mark as to where the
arm was. Just line that back up
and we should be able to just tap it back in place. And if it gives us too
much of a fit, we'll put the chisel back in there to open it back up.
Not too bad. Now here is where you want to make sure you've got it at the right
depth. It should go in easy. Yeah, it does, so
that was it. Just re-tighten what i would call a
pinch bolt.
Well alright guys, that is it pretty simple little project,
especially if yours is marking its territory
in your garage. This is an easy way to stop that from happening
and keep your floors clean. Listen, if you need
