this motor is offered nectar that's vacuum cleaner
looks like the bees that sees that a lot of use you can open NDP as long as the
armature is still fine now the Chinese machine the casing is sheet metal so you
can clamp it in the vise or anything it for the sport how I open it I take us mm
I'll put it against the other planes and you just get and then you get to your
blade now the blade has got a nut that holds it on but when you put a nut on is
really difficult to hold the blade and there's nothing to grip on so what I do
is I put my spanner on and I'll take the hemorrhage cap and what happens is that
loosens the blade can undo the nut and this is your suction blade with a water
the size of a is definitive gentle and there's four little screws that holds
this plate on there linkies I'm just going to get allen key to loosen it
just like each one and then they should unscrew
and
now they're not but the screws are still held on the fiction but now with this if
you put a screwdriver in your time to wait it out is a chance you might bend
the metal and then you'll never get this to line up again so what I do is I just
pick them up back on and I'll just give it a tap with a hammer and that's got a
tendency to loose if you see now everything is loose and often you can
just pull it out a little bit tight and give it a second tip then it comes out
with the beading that failed as a spell apology and then there's a second
beading again it still feels alright but once you've got a nice open luscious I'd
like to replace both and what argue is I was pitiable being put on your put it
off we stick to new bearings in and put it together but this is the little being
put on normally used but because this beading is broken and it's only offer
that live it's going to be difficult to get to be fully in there to pull it off
and this pillar will not work so what I do when we get to this point where we
can't get a grating polina's I'll just take a disc grinder and I'll grind a
slot on each side of this broken bearing and then the two bits should follow in
order to do that you have to clamp it in the vise
but just be very careful if you push on this router you can damage it so what I
normally do is I put a cloth around it and then you put it on the clamp it on
the cloth
and then that is quite speedy and I'll just cut it with a disc to make the big
noises okay now while we're cutting we must be very careful not to cut any of
the of each other but we want to cut to be
what we've done as with coxal the groove in this beading and sometimes we just
force it out the chip come off give it a try
no fuck so going to cut that groove a little bit deeper
got a little baiting off now I've cut it almost through there is the shot I made
a little more cut it but it shouldn't be a problem
and hopefully this one will be easier this one we can pull up with a puller
this is the beading from the top cannot quite in together other half of the
broken one what I'd like to do with the armature before I put the new the
airings are not put it in a roll and spin it and put a little piece of
sandpaper on this commentator where the carbon brushes are you just get it the
nice thing now these prediction of a nice new shiny take it out of the door
with our armature and the two bearings are just a bracelet and all push it in
with a person also you're a liar single day I can feel it I tell ok push the two
bearings into motor this the racket that's what they look like
this segment was nice and clean not apologize into the machine that you'll
see the two carbon brushes day is obstructing it now being and that's how
you can loosen this carbon brush holder and take it out but is why is yeah
that's that's alright what I normally do is I just push the
carbon brushes after way when I slide it in and to do that plastic a screwdriver
in to the on the inside if you want to see a and then you push the one you can
push the carbon brushes of faulty
so you can do one comb and brush static so I put the white on it and then
through these holes we push the carbon versus a force now we've got the amateur
back in its place and then we have this plate that fits
over the top we have these screws that holds it in position so we just put the
log flight on it push it in a little spiciness a lot there should not be any
pressure on the debating but if one of the bearings is not in deep enough you
can just tap it lightly on the only change will set you will slide position
now this not like that I'm partly now it's got little indentations there that
line up these little dots that lines up with indentations on the placing itself
so you can't put it in wrong and once you've got these workers in place the
OHS it's exactly in the middle are being a sheet metal casing you don't want to
over tighten this crease because it doesn't take much to slip them I don't
do it with the torque wrench but you can feel the tension on it and just don't
over tighten them okay I think the armature turns freely now we can just
assemble the whole rest of the machine with plastic key Kizer
and then there's a little spacer then your blade fits on
this diffusers for to lining pens which has to line up with these two holes
again okay bleh and yes the next to tighten this match I
use the spinner like we did when we kick it off just with a little bit of weight
on at NU we tap it with a hammer and that tools actually tightens it so we
get a time and then you put this patient back on again now this is just
compressed fit on the all the vacuum cleaners I am and tested in place but
this when you tap it it all goes out of shape so I just push it lightly in the
vise like this and you don't take this around all the way in like that virtual
motor now we can just run it I'll just put a t-score down you can run it for a
minute and see what it sounded like but they were all being it at wimpy will
turn taught me the feeling was worn out
now when you run this is an awful lot of talk so make sure you hold it quite
okay comfort and that's how our chains creating so many products vacuum cleaner
