on three one two one that's changed over the years and this end down here is where the fluid goes in
and out and there's actually a uh a valve in there so when the tank is almost empty that valve closes
and it keeps the air bladder from expanding out all the way because that could rupture the bladder
so a lot of things have to work here and you can replace the bladders you can unthread this and
pull the whole bladder out of this end of the tank but you have to detach it from this end of the
tank in order to get it out so this part right here is actually part of the bladder it's just
sticking through this housing so bladder on the inside with nitrogen gas and oil around it and the
bladder gets compressed by the oil and then when you turn something on these little hydraulic fluid
that bladder expands back out and pushes oil out so it's a 10 gallon tank but you can only get two
gallons of oil off of it depending on the pressure difference so we'll put about 2000 psi of pressure
into it and it will work down to about 1 300 psi so we get you know about 700 psi delta but we get
at least two gallons of oil now it comes like an inch and a half thread on there but we're going to
reduce this way down to something more appropriate for us that's just a protective cap schrader valve
there just like your bicycle this is the adapter for the schrader valve to the rest of the fill kit
see it's got a pin in there that's going to push that schrader out and the gas is going to come
around that hex bolt and up into the the gauge set the end of this fits into the
hex bolt in there you can depress the straight above with the knob back here
anything no so that should have the shredder valve open so if we open the valve then we should get
gas back out of the tank well there's no gas in the tank then that's not a terribly good sign
i'd like to be some gas in there but if that's the case then we should be able to press that schrader
down by hand oh yeah see i can depress it easily okay so we've got no pressure in the bladder okay
which is not the way they're delivered so it must have bled out over the years i bought this as a
bargain on ebay oh really yeah years ago hopefully it's just leaked out slowly over the years because
these things do have to be maintained that's why i purchased the kit to refill and charge them again
and you can use air you don't have to use nitrogen but nitrogen's of course better because it doesn't
deteriorate the rubber bladder that's inside there because this is so fragile we're going to
remove this and put the cap screw back on which protects all that stuff our nitrogen bottle here
is not just for charging up the accumulators for testing the lines too so we plumbed it into the
high pressure side of our system and it's just a matter of closing the ball valve so we'll test the
front and the back and andrew has added a gauge over here so we can see what we're going up to
and close it up you shut it off yep all right we're leaking somewhere i can hear it
no that's tight watch this
that doesn't seem right making more noise as we close it off oh see that was loose as a goose
and then this is the regulator portion of it oh it's getting quieter it's good
so with the pressure regulator and what i'm doing is i'm loosening the nut on the top of the spring
that lets the pressure push the ball off the joint leave the pressure down
well so far we've got one leak but it's in a nice spot i mean
it's easy to reach it's not one of these this would be a bad one uh
andrew had a great idea we took the handle off and tightened the nut that's down here against
the base that seems to have done the trick much easier than replacing the whole stinking valve
no leaks that's fantastic because that would not be a fun place to change one no
you don't know what the end cap yeah we don't care about end caps
ah end caps are okay to leak so we're over 2000 psi still there's one right there
there you go that sounds like it's leaking somewhere hang on that can't be plugged up man i
hope it's not this one i think it is though okay so to get to the leaky fitting we went and cut
a hole in the boat that's actually the cedar from down below and there were two unions in here so we
removed those drilled and tapped holes fashioned a hatch plate that'll go on top of there this was
actually plan a we banded plan a for b because b was easier so now we're back to plan a i like
this better is it leaking oh wonderful fantastic nice job there's one small league right here like
i missed yesterday yeah then i know that didn't test on top of the deck yes oh i did that that's
just one fitting up there that's no big deal but this one has a leak no just this ice this pipe and
it's coming away oh perfect yeah it angled that a little bit yeah that looks fun yeah yeah excellent
well andrew and i have finished finding and fixing all the leaks actually andrew did most of that
thank you very much sir of course so our nitrogen bottle there now gets to charge the bladder inside
the accumulator and there's a chart you can use to look up how much volume you're gonna get out
of this tank we're gonna get about two gallons because we're gonna charge it up to about 2000 psi
and let it come all the way down to 1350 and then it's going to close the poppet valve so that range
of pressure gives us about 2 gallons you have a higher range of pressure as you get more fluid
but then you get too low on the pressure and things don't start working very well so
we're going to try it off like that to start with and then we can change it if need be and it is one
serious ass tank i mean this one weighs a lot more than that one and my accumulator here is a parker
they're made by hydak and probably other companies as well and this indicates that it's a bladder
type there are three types and we have this one here this is a diaphragm and this is a piston see
that thing just moves up and compresses the gas when the hydraulic fluid comes in the cool thing
about this is you can use a full stroke because you can connect this over to a gas cylinder like
that and what it would do is it would use the oil coming in to press this gas over into another tank
in fact probably a whole rack of them the downside to this one is it's subject to contamination
little dirt comes in with the oil and it gets in here and it's just like a you know it's
like sand inside your carve your piston that's doesn't handle it well these two type take uh
contaminants better but this thing's eventually going to break you can imagine if you had a gas
cylinder out here and you're pressing this out into a cylinder when it breaks oil is going to
go into that cylinder too so you're going to have you know that's going to be a mess
so standalone ones are often bladders because they handle the contaminations better this was
a diaphragm so it's just got this rubber diaphragm that goes across and it goes up and down smaller
ones often have diaphragms mine has a bag and this is nice because this is easy to change well
somewhat because you can take the bottom out you take this nut off here you can pull the whole bag
out and put a new bag in so they got to be checked every once while to make sure that you haven't
ruptured your bag if you find your pumps are cycling a lot more it's probably because you've
lost your charge or your bag has ruptured and magic is down here in the bottom so when this bag
pushes the oil out it eventually starts bumping into this poppet valve and shoves it down and
seals it off and that's why this thing's so big that big poppet valve comes down on there it has a
stem that extends in the middle [ __ ] we'll take our fitting off here so you can see inside there
okay oh that didn't look good there's supposed to be a poppet valve stem coming through there
i may not even have a bladder in this thing yeah yeah we do we got a bladder in this thing it's
got an air chuck at the other end i can see all the way to the other end and i can see the valve
stem down there really there's no bladder in this thing let me take this all apart and we'll just
make sure okay that came off easy man i don't need no stinking spanner wrench so we removed the purge
now the spanner wrench would normally take this thing off tight wrench works just like most things
now don't change the order of any seals and pay attention to them
now there's an o-ring down in there supposedly but this thing goes in
yep should have a seal around it somehow yeah it's got a big seal on it you'll see this when
i get it out of there if i can get it to get it out of there so i got the seal off
and it should oh my god how's it on there it's got a metal ring oh it's split so i have one
that folds in half so you just pull and pinch it together now to come see that wow that's nice
you know everything's so it can just barely fit through
and then it's got an o-ring and a retainer so putting it back together it looks like that and so
this piece can't come out because this seals around that but you can get this
out because you can fold it in half clever design off to buy a bladder so then it's
like what is that schrader valve attached to that was weird that we even have that
from what i've seen is most time that top part is part of the bladder now could we use this
with just gas in there yeah but that would absorb pretty quick it wouldn't last long oh that's weird
this is a bladderless tank
the hell would i buy no they cut the bladder off jeez and it looked like it was a new bladder
though it's weird so order a bladder okay there's our model number that's worse than i thought
because i don't just need the bladder i need the poppet valve that goes in the bottom too our parts
have arrived from parker including a bladder and a poppet valve this is the uh part that was in
there it is a pop-up valve just missing the poppet there's the pop-it valve with the pop-up so as the
bag expands see what it does it comes down here and it shuts off the whole tank so the bag can't
actually extrude down through here and tear itself apart because that's what it would do nothing too
fancy about that but you would not believe the cost of that i still came out a little ahead of
you know buying it this way in parts and putting it together then i did uh buying a new one but
hydraulics ain't cheap oh you came with a fancy fancy how-to instruction manual so it's all yours
a piece of wire can we attach that to it
see they hang they make a little tool that threads on there don't get it focused you can
make a little tool that threads on there and then you pull them you know put it on a wire
through here and then pull it through or a rod can we what thread is that maybe we just made
yeah this one has to go through the hole so it has to be small enough
um we can use a like a valve stem cap like that throw it on there just have something behind it
well we just jig weld a rod onto that sure you can weld yeah make a tool
that's probably pretty good click right yep turning ever so slowly
all right i hear it over here yep i can hear it is it moving just started moving
it's moving a lot yep it's slowly coming
right there okay so now we can increase the pressure flow yep increase the flow
without a regulator you don't need much we're going to what 1300
whatever says how long this takes but apparently it's
not quick to turn it off still dropping to zero just bothers me it drops off to zero
here yeah yeah that was right now it shouldn't have anything coming in
oh hey it didn't go all the way down that time it's okay it's just gonna take forever right yeah
so what we learned that they don't tell you in the videos about how to fill these things
it takes a while because it's just this tiny little hose and we're not even using a regulator
we just open this valve and it's balancing these two tanks but only now after like five
minutes of filling can i turn this one off and that needle finally doesn't drop back to zero
and i suppose that makes sense because it's a little tiny schrader valve that holds back
all that pressure so by being so small it's very strong because it doesn't have a lot of surface
area for the pressure to push on so you just gotta wait for it to get past a little booger
uh 400 then oh well that's good making progress well the cylinder is balanced
out but we're still going to need another one so we're off to get another one but we got some wasp
and they're all cool about it until we start moving the cranes they die starter fluid
that's it
oh my god
what was the pressure on the cylinder it was just under 1300 so i bumped it back up to 14 and called
it good that's fantastic yeah yeah well done okay that's it the accumulator is in i'm happy about
that more hydraulics coming hey guys regina here did you see that live video doug put up
what is this miss oklahoma's coming to the vip launch party and she's gonna chris in the boat
oh what do you mean i'm miss sv seeker that's the vote i got down in the bilge yep all the
boys like me best and look i got a tiara and i got a sash so i don't really understand i don't know
maybe we should just have a contest or something yeah yeah because i can hold my own against her
yeah uh-huh i'm not i'm not really sure what my talent is yet but i still i still got a little bit
of time to figure that out anyway you want to come see me take on miss oklahoma then well you better
get your tickets go to thechestfoundation.org forward slash katusa and get your tickets to the
vip gala launch party of sv seeker on august 21st at the port of katusa here i am miss
here i am your favorite rat
do
