00:00:01
power tool repair channel, and today we’ll
00:00:03
talk about why you have to look very hard for a
00:00:06
clear one, why pull the arc on the commutator, what
00:00:09
needs to be done, in what cases you need to bleed the
00:00:11
commutator, which ones you don’t need to
00:00:15
bleed the whole thing, we’ll now sort it out,
00:00:19
look, there’s such a situation, why
00:00:23
can this happen to everyone? so
00:00:25
we changed the new brushes and sincerely and then it
00:00:28
continues now we’ll see
00:00:40
even a little I can already hear from the sound
00:00:43
that it’s working for a few minutes somehow the
00:00:45
sound is wrong and you can see when it’s sparking and
00:00:48
so dragging it out a little risk
00:00:49
first of all, of course, I
00:00:52
disassemble the tool; I disassemble the tool; I
00:00:55
look at the bearings and you see, just like
00:00:59
in this rotor, you can see that the metal rotor is the
00:01:03
actors, the stator, and this can also
00:01:05
be normal; we see it sincerely;
00:01:07
maybe in this case it was so
00:01:10
sincere, and most likely because of this from the
00:01:13
shadows and this is how the collector has worn out on
00:01:17
this collector, let’s say nothing,
00:01:20
sandpaper is not there or there’s no way to help him with alcohol,
00:01:23
he needs to be sharpened on a machine
00:01:26
such a development he has here also I already
00:01:32
disassembled and installed new brushes
00:01:35
replaced the bearings are also flying the situation has
00:01:38
already been taken into account let’s replace a good one sending the
00:01:40
bearings further, it sparks, well, we
00:01:43
look and now I’ll show you how to
00:01:46
check and that this problem with
00:01:47
the collector is with the rotor at the top and
00:01:59
still there, look from this side
00:02:07
so it speeds up I admit it’s not on
00:02:17
I disassembled the tool with a boiler, look, there is
00:02:22
a little bit of output on the manifold
00:02:27
like this if you look, but it
00:02:31
doesn’t really catch the eye either, but it’s
00:02:33
a little different from what it is in this rotor, that yes, there’s
00:02:36
such a big output
00:02:39
that it’s already one hundred percent that needs to be
00:02:42
here, you can try and as
00:02:44
many masters recommend, wipe with
00:02:48
alcohol about cherishing each
00:02:51
each of these cupra lamellas is more expensive, but in this
00:02:55
case I already did it all, tried it,
00:02:57
in short, this is what came out: a spark
00:03:00
further sparks, we also see what
00:03:04
could have broken out of the collector faster due to the fact
00:03:07
that the rotor is a box the stator and there were bad
00:03:12
bearings, I replaced them and from this it
00:03:15
goes in any way, sincerely, sincerely goes
00:03:17
or the temperature and is generated from
00:03:20
this metal becomes soft and the
00:03:21
collector is developed from this sooner
00:03:23
so we give 100 cows for grooving,
00:03:28
we will collect it then and check after
00:03:31
grooving how the collector works, it was machined by a
00:03:37
what it looks like: are the lamellas more expensive? Are we
00:03:39
going to install this rotor more expensive now? the
00:03:46
collector is very worn out; this is from an old fiolent;
00:03:58
without 6 they will now check for sincerity and
00:04:01
see how after the grooving they work,
00:04:12
works well, on the other hand
00:04:21
does not spark the arc does not pull everything everything we
00:04:25
wanted now food fiolent
00:04:35
also works well, it doesn’t draw an arc, it doesn’t
00:04:38
spark, this is the result after
00:04:42
the collectors, well, of course, and replacing
00:04:44
the bearings, this is unambiguous, and our
00:04:48
tool works under the volume of current, if you have
00:04:51
already changed the brushes with new ones, and if, in
00:04:55
short, the first thing you need to do is
00:04:58
replace the bearings, look, then
00:04:59
press and if this is the whole thing, then the
00:05:02
collector sparks, then the script
00:05:06
needs to be sharpened a little if there is an
00:05:08
adequate turner, it won’t assemble the new collector
00:05:11
a little, the annet grinder will align it as it should be according to the
00:05:14
factory ones and will
00:05:18
without a spark, like these two, let’s say,
00:05:20
old devices, and so like this make
00:05:24
sure that your tool is not skrill
00:05:26
bearings so that they spin well
