- Hey, guys, welcome back.
In today's video,
I'm going to show you how to remove a seized
and stubborn lawnmower blade adaptor.
So I've got this lawnmower here.
It actually runs good
but look at the body.
It's all rotted.
Check this out, man.
It's rotted right through.
So I went to take the engine off
but the blade adaptor's stuck on
and I cannot pull the engine.
So I'll flip it over.
It's got a huge blade adaptor here.
It's not gonna go through the hole here,
so I will show you how to remove that.
It is definitely seized.
Now, you're gonna have to flip your mower over like this
to do that.
So try to flip it with the air filter up,
the carburetor up and the air filter up if you can
because if you don't,
you may get some gas in the air filter
and sometimes, you'll even get some oil
in some rare cases.
Now, what you could also do
is drain your machine of all the fluids
before removing the adaptor.
So the first thing I do
when I'm about to remove a seized blade adaptor
is I spray some penetrating oil right inside here.
And also at the back right back here.
Now, if you do spray it at the back here
and you flip the mower back upright,
it will allow it to go down the cracks
between the shaft and the adaptor better.
Now, the first thing I do is put a bolt inside here
and I always put a bolt that was smaller
than the actual hole where the blade bolt went.
So it'll go right to the bottom.
And most times, I'll use a two-jaw puller like this
where I would actually grab the adaptor like that.
So the two jaws would be locking in on each side.
However, in this adaptor here,
I've got two holes.
So I will be taking advantage of that.
Sometimes the two-jaw puller slips off the adaptor,
so today I'm gonna show you how to do it this way
and then I'll show you how to remove another seized adaptor
using the two-jaw puller.
So today I'll be using a harmonic balancer puller.
So you want it on like that.
Then I'm going to get these bolts into the holes.
And then what I'll be doing is putting the nuts
on the other side.
So make sure you have them
in the full length of the nut here.
And now what I'll do is tighten up the puller slowly.
Now, make sure you've got the bolt here right in the center
of your puller.
Sometimes the bolt can tend to fall off the puller,
so keep an eye on that.
Everything is secure back there.
You can wear safety glasses if you want.
And now what you wanna do
is tighten up your puller slowly.
Hopefully the adaptor will come loose.
And I've decided to actually wear a glove here
and some safety glasses.
So now you have to hold the engine
so that it doesn't turn
when you're trying to tighten up the puller.
So if you're hitting a snag like I am right now,
or even the puller won't do it,
you're going to need to heat up the blade adaptor.
So as you can see here, the adaptor's not budging at all.
It's actually bending the bolt.
So what I'm going to do is get the acetylene torch out
and I will heat the exterior of the blade adaptor
and it should come off quite easily after that.
Okay, so at this point,
I will use the oxy acetylene
and I will heat this up.
I have put a shorter bolt here
and also, a good tip here, guys
if you don't have an impact to tighten this up,
and you end up having to hold this
as you can lock it in like this with another wrench.
(flame whooshing)
And if you're going to do this,
make sure you have removed all the fuel
from your machine, guys.
(flame whooshing)
So I'm turning it slowly to heat up everything.
And try not to heat the shaft
because you don't want...
The seal could get too hot.
(flame whooshing)
And now we'll just tighten up the puller again.
(puller turning)
And now it is coming off.
(puller turning)
Maybe my bolt is too short.
Okay, so I will put back the longer bolt in there.
And I've got my leather gloves here
because this is extremely hot.
(bolt clanging)
And it is coming off easily.
(puller turning)
Et voila.
So this adaptor's still good.
I will save that.
And now I can save the engine
and get it out of the old body.
If you're concerned about the oil seal getting hot
during the process,
you can throw some cold water there.
(sizzling sound)
So it wasn't too bad.
(sizzling sound)
And now I'm just going to remove this adaptor here
using the two-jaw puller.
Again, I'm putting a bolt in there.
Now you want to get the jaws at the bottom here.
And now just try to hold the jaws with your hand if you can
and just tighten up the puller.
If it gets a bit hard to hold it with your hands,
just put a wrench in there.
Now this adaptor's seized
so I will need to heat it.
If you don't have oxy acetylene,
sometimes MAPP gas will do.
(flame whooshing)
(popping sound)
That pop you heard is because I've got pressure
with the puller.
And the adaptor's getting loose on the shaft.
It was that quick.
(flame whooshing)
(water pouring)
(clanging sounds)
And it's coming out.
And I'll put a bit more water here
to make sure the seal is not overheated.
Now, I don't always need the torches
but today I needed it for both of them.
And believe me, if you do have oxy acetylene,
it will save your bacon all the time,
and you're not going to destroy stuff taking it apart.
So hopefully my video has helped you.
If it has, please like it and share it with your friends,
and I do wanna recommend, guys
that if you do a lot of small engine repairs
that you get yourself a good set of oxy acetylene torches.
It will save the day all the time.
Thanks again for watching
and make sure you're subscribed and have a great day.
