- Hey guys, welcome back.
Today, I've got a leaf blower here.
It's made by Schroder.
It's not a company that's well-known,
like STIHL or Husqvarna.
Now, the reason I'm making a video today is
because the customer dropped it off here.
He was honest and told me,
"Hey, I ran it without oil in the gas.
You can have it if you want for parts or whatever."
So, I decided I would make a tear down video
to show you what happens
when you run your two-cycle equipment with straight gas.
And here's a close look at it.
Here's the model number.
SR-6400L.
Now, I'm not sure where these are made.
Maybe in China, I'm not sure.
The only place I've seen them for sale is on Amazon
and they're well priced.
And if you look at them closely guys,
they do look like they're well built.
I would definitely buy one if I was looking for one.
And it's a natural two-cycle.
It's not a four-mix with valves like STIHL.
So, the customer, like I said, brought it in and said,
"Hey, I ran it with straight gas, you can have it."
He was very honest about it.
You can see, the gas is still in there.
It's not colored at all.
So, let's take this thing apart here.
And I think what I need here is a Phillips screwdriver,
which is odd.
Usually, they're Torx or Allen screws.
I'm just so used to using my impacts with the bits
that now I don't wanna use a screwdriver
and turn it by hand.
(driver tool roaring)
(driver tool roaring continues)
Okay, let's get this off.
All right, I think I'll take off the air intake over here
or just right here.
(driver tool roaring)
(driver tool roaring continues)
Okay, let's get this cover off here.
It's a bit loose.
(hand knobs squeaking)
Now, by the way, this looks like it's a German company
because the German flag is on it
and the name is obviously German.
(plastic cover clanks)
So, this machine, guys,
looks like it's barely, barely been used.
Look at the air filter, it's like brand new.
Now, for some reason, all the screws are loose here.
Look at that.
That's why it's all loose like that.
(driver tool roaring)
Okay.
I'm gonna take the carb off.
And this one uses Allen screws.
(driver tool roaring)
And this is your typical two-cycle carburetor
that you find on a lot of other equipment.
(driver tool roaring)
I've never taken one of these apart,
so I'm not too quick on this one today.
Okay, it looks like I might have
to take these two Allen screws to get this off.
(driver tool roaring)
And there we go.
(metal clanking)
Okay, let's get this plug off.
(spark plug squeaking)
There we go.
(metal clanks)
Okay, more Allen screws here.
(screws squeaking)
Man, this thing looks brand new, guys.
I'm hoping to find another cylinder kit for it.
If you happen to know where, please comment below.
(screws squeaking continues)
There's another screw here.
(screw squeaking)
Now, if we look through the exhaust port,
you can see that that piston is scored.
All right, I'm going to remove the cylinder.
And those are Allen screws again.
(screws squeaking)
(screws squeaking continues)
So, I like to loosen them by hand first
and then I grab my impact.
(metal clanks)
And I think these Allen screw heads are number four.
(driver tool roaring)
(driver tool roaring continues)
Okay, guys, this is always the exciting part.
Taking the cylinder off and looking at the damage.
Oh, man, it's tight on there.
There. (pry tool clanks)
(metal squeaking)
There's some plastic behind there.
Man, that's tight. (sighs)
I've never had such a hard time
getting a two-cycle cylinder off.
Look at that spider.
Look at that crazy spider in there.
Better be careful here.
I'm not sure what it is.
Okay, this is a bit odd here
to have such a hard time getting a cylinder off.
(plastic piece pops) There.
(metal squeaking)
There we go.
It was actually this plastic piece here
that was rubbing on the cylinder.
So, I think this hole here blows air
to actually cool the engine.
Wow, this is super, super bad.
And it's really bad on the intake as well as the exhaust.
Wow.
One ring is loose.
And the other, the one at the bottom is stuck.
And let's look at this cylinder here.
Look at that, it's all scored up badly, very badly.
Wow.
Yeah, that's toast.
When it's this bad guys,
you don't bother sanding or trying to fix it.
You basically have to replace the piston rings
and the cylinder.
Okay, so it's very easy to see
that the cylinder, piston and rings are shot.
They're just not repairable.
Now, I wanna show you a few things to look at
before you go and buy a cylinder kit
for your two-cycle equipment if it's in this bad of shape.
There's a few other things you wanna check first
because you could be putting a piston, cylinder
and rings in your equipment,
but there could be other issues that were caused
from running it without any oil in the gas.
And that's what I wanna show you right now.
So, on any two-cycle equipment,
that's burned up like this one,
what I check, before I put a cylinder kit,
is I grab the piston like this,
and make sure the connecting rod's right at the top here,
and then what I do is I pull up and down to check for play.
So, if there was a lot of play here in the connecting rod,
where it's on the crank shaft,
there's no point in putting in a cylinder kit.
That would mean that running it without oil in the gas
has damaged the bearing in here
and there's no point in fixing it
because you're just going to end up
with the same problem again, a damage engine.
Now, this one here is quite tight.
And I am gently,
well, actually, firmly pulling up and pushing down,
and there's not any play that is of any concern in there.
So, that's a good sign.
That means it's good in here,
where the connecting rod is on the crank shaft.
But another thing to check is to see if there's any play
in the crank bearing on this side here.
So, I'll take off the recoil.
(driver tool roaring)
And I do the same test here on the crank shaft,
is I grab it and then I push up and down
to check for play, even sideways,
and this one's nice and tight.
So, I would be confident in putting a new cylinder kit
in this leaf blower.
Now, I can see one of the crank bearings here
and it does not look totally discolored.
And the connecting rod here is not discolored as well.
It's not blue as if it got really, really hot.
Usually, the piston rings and cylinder will give out
before you damage the crank shaft
or the connecting rod here.
So, yeah, I think this would be a good candidate
if I can find a cylinder kit for it.
I'm gonna check online, but again guys,
if you know where I can get one, just let me know.
I will buy the kit and make a video of me fixing it.
And definitely I must drain the gas here
so we don't get a repeat of what just happened.
But again, look at this machine guys, it's like brand new.
There's no dirt anywhere on this machine.
So, I hope to find a kit, guys.
I really, really hope so.
Anyway, I hope you've learned something here,
in this tear down.
We all know, we shouldn't be running straight gas
in two-cycle equipment,
but hopefully, the little techniques I showed you here
in checking the play in the connecting rod
and the crank shaft will help you in your future repairs.
If you have any comments on this machine guys,
please comment below.
And if you actually own one of these machines,
make sure to comment, guys,
'cause I'd like to get your feedback on these machines.
(table squeaks)
So, when I actually grab the machine, the plastic,
it actually feels of good quality.
Everything feels like it's good.
It does not feel cheap.
Even the hose here and all that looks pretty good.
And I've seen good reviews on Amazon
on these machines actually.
So, with this machine here,
we know exactly what the cause of death is,
and that is no oil in the gas.
Easy diagnosis.
So, that'll be it for this tear down video, guys.
I'm just going to hang onto this machine
and all the parts here in case I can fix it in the future.
And thanks again for watching, guys,
and make sure you're subscribed to my channel
and I will see you next time.
Have a great day.
