let's pick up where we left off let's repair the printhead Howard my press tag
left a list of things that needs to be done to the press so let's go ahead and
tackle that okay so my next move is to this is printhead number one this is
what is considered the stroke stop it generally has a lever with a little
swivel nut on it that hold this in place the previous shop as you can see it's a
little marred up here they just had a bear bolt and a piece of rubber in there
so the idea is this goes forward the cylinder kicks this forward so the
squeegee is one of the V squeegee styles it floods kicks it forward and into
that's a print and it comes back and then here this is what stopped it this
whole make it stop if you're only doing a little chest print so this is stuff
this has to be replaced we're going to replace four of them out
of the six just to be safe head number one in particular this whole rail this
is just a huge new piece of aluminum we're going to replace this and a
handful of other things I'm going to go head to head and show you what needs to
be replaced with each one of these so it's using the blowout gun to clean up
some of these threads and just some of the ink that's all over the place and I
noticed that it did start eating up some of the paint on the press I'm not going
to go too crazy with cleaning everything up
however I did take the blow out gun to clean up some of these areas here I
think I'll do that for the rest of the press but for the most part I'm not
gonna do teaching much cleaning up but I am just gonna clean some of these
threads and in parts just to make sure that they're not all gummed up with ink
here is the part of the press if a power will get off of me
where the little standoffs go and they're missing I have no idea why
that's interesting isn't it there we go I'll put that standoff on there and then
put our lever on now we're good to go we have four other spots wrong but it go
ahead and install these pretty simple hey we got our standoffs installed
okay so ear tech number one this needs the most repair it needs to cylinder
replace the well replace I'm going to show you guys how to go about taking
these heads apart it's fairly simple so the first thing I'm going to do is I'm
gonna flip this thing upside down okay you guys saw I flipped it over I'm using
a couple two by fours there are flip switches and control
knobs at front of the head that you do not want to turn this thing over on and
destroy those so the first thing we're going to do is we're just going to
disconnect this hose here all you do is you push it in you pull the hose out
then we're going to loosen up these little ratchet levers this other side
here it doesn't have the lever so I'm gonna have to get some vice grips for
that come here Apollo
and before slide this off you can tell that the spring here will either need
some adjustment or replace it altogether because it should just stay towards the
front when you put your screens in here push it back and then it moves forward
but we'll look into that here in a moment so we're just gonna go
ahead and slide this back we have our main hose that's feeding these cylinders
that hold there are the stream clamp cylinders so we're going this thing back
and we're gonna set this guys right now the next thing I'm going to do is I'm
going to take this stop block which this is one of them that needs to be replaced
so there's old one there next thing I'm going to do is disconnect these hoses
and unscrew this bolt here and this hose clamp here that hold the stroke cylinder
in place and this thing is supposed to it's supposed to move back and forth
like this so that way it will be able to recenter itself and I'll show you guys
what I'm talking about okay have my crescent mentioned going to
loosen this nut which holds down the cylinder next I'm going to undo this
hose clamp all the way there we go just go ahead and set that aside next thing
we have to do is remove these hoses here again you just push in the fitting here
and then you pull on the hose sometimes these hoses will be a little stubborn so
you might need to take a wrench without clamping your hose depress the
shoulder of this quick fit this pushing style and then just pull your hose down
now it looks like they had zip tied this to it there's
go ahead and cut that I'm looking at the other heads they don't have that on
there but maybe that's a good idea so now the stroke cylinder is free next
thing we're going to do is go to the front this symbol it and pull the
carriage out here we are at the front of the head there are four bolts that hold
this entire assembly on it's a half inch so I'm just going to break those loose
and pull them out
what I'm doing is making sure that there is enough of the frame rail up the heads
that way when I take this off the whole thing is not going to drop down on those
control knobs and switches okay all of our bolts are out so I'm just gonna
slide this out of the way you have to be careful because there are the hoses that
activate the the clamp down nobs or excuse me the the screen's clamp
cylinders so I'm gonna set this somewhere where I'm not stretching these
lines too much that should be fine we got enough slack now the next thing I'm
going to do or make sure that these hoses are out of the way at this point
I'm quiet the whole periods out the Frog
before I can carry this carriage away okay one of the things I have to do is
disconnect these two hoses here they activate the flip cylinder so I'm going
to pull this fitting back pull the hose out there's one of them and I'm just
going to replace this whole line because it's nasty and the hose needs replacing
anyways and here we are we got these hoses taken care of we're gonna set
those aside for now and let's remove our carriage and then look at the wheels on
the workbench
what's that
yeah I remember that
okay now that we have the carriage all taken care of cylinder replace we're
going to replace this grille first thing you have to do is remove these hoses
here they go to the screen clamp cylinders set this guy out of the way
the next thing we have to do is remove this rear stroke filling there clamps
you can see there's a little water in it that's why that cylinder stroke cylinder
number one is going out however this is a 7/16 bolt keep in mind that the back
of this is a supposed to wiggle that's so the cylinder can flex and it's kind
of recenter itself and does that at the rear and the front so what's going to be
sure to put this back just the way it is let's go ahead and remove this it looks
like they have a little bit of Loctite or something on there to keep it from
backing out we'll use a little bit of blue loctite
here's the other one looks like it's a locking nut and has a little nylon in
the front so we'll be sure to put that upside down in the front we'll go ahead
and set these aside here's our little clamp or hold down see they have a
little bit of grease here at the back of it you probably toss some on the new
railing the next thing we have to do is remove this row the entire rail itself
looks like it's four bolts here two here two at the front plus button do
don't let me drown don't let me try
all right so the next thing I'm going to do see what is up with this spring might
just need replacing or it might just be bent up a little bit I'm gonna press
this forward take my life hopefully I can grab the back of it yeah all right
it looks like at some point this spring was over bent a little bit and hopefully
I can straighten this out okay I was able to take my vice grips and a pair of
pliers looks like I straightened it out pretty good coiled up a little bit
hopefully this will do the trick let's install it and see
now that I've gotten this far last thing I'm going to do to this printhead is I'm
going to replace these two rear clamp levers so I'm going to go ahead and flip
this thing over
Mazz will go ahead and reconnect this clamp here or this hose Apolo shut that
off just make sure we got a good connection
push it right in there yeah and we're gonna get the dog off the leg all this
here we're replacing so I'm just going to pull that out toss it aside that is
not for you to chew on deed
and I'm gonna throw the lights and the dog doesn't eat so the next thing I'm
going to do is replace these rear screen clamps this part the the rear screen
plant you can move it forward or backwards to you can use different frame
sizes so here are my clamps here my two little knobs I'm going to use let's go
ahead and try and remove these things so I think for this first one where I'll do
is I'll take the vice grips clamp it down real good and then I'm going to use
the knob itself to undo this let me disconnect this and get it out of the
way
robear dad the other sides are gonna be a doozy because the lever broke off
okay there that goes here's old one we'll get rid of that take one of these
new ones once I get through the aluminum I'm gonna put just a touch of thread
Locker on the tip here I'm go ahead and put one of these little knobs on it when
I got a chance to read this through a little go ahead clean that up
get in there thankfully out on this now at this point I'm gonna have to be
pretty quick before that it's red locker dries okay you got my 9/16
let's lock this bad boy down thread it in there steep as we can that should be
pretty good now once that thread Locker dries other thing we'll be just as tough
to remove as the other was it's not practically impossible now let's take
our 9/16 wrench and we'll grab our channel and we're basically going to
repeat the process except this will be a little bit more of a pain in the ass
well that's not good okay so I'm gonna have to do is I'm gonna back this thing
out and then reverse this thing out because obviously we just broke it
hanging up this back out a little bit it's gonna grab my wrench here hopefully
I can back it out so let's go ahead and move this guy back forward drop up our
threadlocker here put it down on the inside I'm gonna tighten it until it's
my snug then we'll let the threadlocker do its thing so I'm gonna go ahead and
tighten this up make sure we're plenty far away from this aluminum because we
don't want that to lock in there and that should about do it I'm gonna go
ahead and take this hose I'm gonna cut off this little end piece here it's got
a little bit of an indention may or may not have to do this I just like doing
that because to me it seems like that's gonna make a better connection again
