Beverly and I absolutely adore the ever

soccer and a little heater

however we there are some several issues

which is it needs servicing on a regular

basis

it needs servicing every 1000 hours

mm apparently 2000 hours it sounds like

a lot for lot but when you use it as

much as we do and then in winter or sort

of like autumn to spring you're talking

every three months or for the summer

Siri summer period we serviced it before

we went out and by the time the end of

this the summer is done because the

weather's just not the nicest in the

evening sometimes then it needs

servicing again you can send the

servicing away and we found that send it

away it cost about 150 pounds to send it

away oh you can buy an EV us bucket

service kit and that costs 20 pounds

so what Beverly is going to do today is

show you how she does her service

because we definitely prefer to spend 20

quid rather than 150 this may look like

a standard socket like a long socket

you'd use and spark plugs but it has a

huge big slot in it and what this is

this is the upper smacker extraction

tool for removing the glue plug the glue

plug is ceramic and you've got to be

careful how you move this lets the wires

come up inside so you can put the wires

up and do the extraction so what else do

you need then the one final tool you'll

need is the good old standby cloth

kaffir tip and in case you're wondering

what that's needed for when you remove

the diesel from the ever it's a good

idea to some of this handy lift the

diesel lineup and stick it to the

bulkhead so it doesn't dribble these on

everywhere

[Music]

so with all things boat related the

first thing you have to do when you do

anything is get yourself into where

awkward positions and somewhere up there

is Beverly getting the a bus back around

job number one is unplug this so the

unit can't operate and for that you will

need your flat bladed screwdriver which

you basically took into that little slot

tuck into that little slot just there

and it will pop up sorry you didn't get

to watch that but I'm not safer

Beeblebrox and I don't have three hands

so that pops up and when it does the

whole unit just comes apart and I think

I really do need to be safe on people

blocks so it just comes out like that

next use a screwdriver to remove the

diesel light which I will then gaffer

tape to the bulkhead to keep it out of

the way we undo that screw that bolt and

these support screws and the whole unit

will just lift tight ah so um this is

the air bus back and as you can see here

this you had to stick your finger and

there didn't you

it's opened by these clips at the back

this falls off so as you can see this

blower blows air over all this and out

here the combustion chamber is on the

inside of this metal piece so the two

never mix no this is the electronic

control this is the brianne's no no no

and it's held in by that little tiny

clip and this screw right so let's get

stuck in

nutkum site push the clip in now this

will just lift right like so it's not

easy to remove and these wires I say

them they gently pull them off like that

this unit here is the temperature sensor

okay I see it

and so we'll be removing that in just a

minute I can't remove this it's got a

little slot oh I see it

just there so I can just push that in

and that will just remove that was the

end piece yeah once that's removed that

will be easier now yeah give me just a

bit more leeway yeah look at that much

easier so just coming back to us to do

this is the diesel pipe which comes up

and through into there right okay

this is the glue plug this is the

temperature sensor which is held in by

this clip so I'm gonna remove Sony just

a little you see that oh yeah you're not

just sight and that's the temperature

sensor yep right oh and that makes that

much easier to just have it to the side

doesn't I've now got this which is the

globe book so what I'm gonna do now is

I'm going to carefully and this is where

you need the extractor tool is that

right now this is the boot first ya

gotta remove this rubber boot carefully

and slide it back everybody everything

I've ever seen about this unit says just

be careful with this bit this is the one

bit your novel that Brit things so grab

the wires yeah because the wires a very

very fragile they're very very stiff as

well they are incredibly stiff and

that's why you need a particular episome

strapped a tool in there yes so we're

good so

remove the globe look of course we can

service if we don't okay so we get this

that's the ever Spock soul however as

Beverly says we have made one ourselves

out of a so you put that in and then all

you do is you don't you hold it so that

it doesn't twist sideways you don't put

any sideways force on this plug yeah you

just want to break the seal that's it

once you get the seal broken you're good

yeah and then then unwind it but all the

wires as well it comes right so let's

have a look at that glow plug as you can

see it's very suited

however the ends are square that means

that the glow plug does not need to be

removed or replaced as need to be

realized the ends become rounded when it

comes to replacement time but as you can

see it is incredibly dirty and salty so

we have got to remove all that sort and

the best way to do it finally is a

little bit of wet and dry very gently

okay so what I'm gonna do yes I'm going

to remove the motor

Kwasi drive screwdriver yep and off

comes the motor that's it and this is

the internal chamber this is the

combustion chamber where the air goes in

this is the diesel and air mixing tube

okay let's have a look at that cuz um

didn't see that's where's that was why

is it this yeah that's the diesel and

air mixing tube right okay an arrogance

sucked in through these little slots and

spins around inside and it does things

but these are where you need the Torx

Tula take these out and then notice that

somebody is serviced at at one point and

use the known Torx one here so we've got

an old one in here seems to work but you

know okay

the gaskets in the kit will be for this

area here it will be stuck to the back

of this okay yeah the service kit comes

with all the new gaskets it does um

so we always just replace them we do all

right and there is a very very tiny hole

which you want of trouble seeing very

tiny hole just there so I say okay well

I can see where you've got your putting

your thing that's the air intake for the

hole burner okay that little bit there

mixes the diesel right with the air a

little and that blocks up the suit right

and inside here is the copper goes the

copper screen that the glue plug fits

inside and that is a sod to get out and

you will destroy it as you remove it

right there's a new way to get it out

without wrecking it it's just not gonna

happen

okay so I don't have the special handle

for Torx bits but I've got this and I

can use it just a brick with thread yeah

there we go

Beverly had what it said on the talks

bitterness I just said t27 Beverly's

resorting to power tools because this

particular one does not want to go out

it always happens when your video in

things but this particular knot or bolt

or whatever

it's definitely not playing ball and for

whatever reason it's incredibly stiff

yeah oh right so I'm gonna remove the

burner chamber I've got a tick this all

right because it's got the diesel fuel

line this is the burner chamber and you

can see way down at the bottom you met

you turn your light on and see way down

at the bottom oh yes there's some soot

up here at the top yes I can see that

that's where the diesel feeds in from

this combustion tube so need to get

something down there to clean that that

is the air hole the Christian Chamber

really tiny yeah that's it you know

that's what those are the burn in there

and I still got to get the little

Gosling out from in there and this is

the heat exchanger

which is really just a big chunk of

aluminium that's all it is hmm yeah so

once you break it down into its

component bits there's certainly nothing

to get worried about the old gasket come

oh this is the old gasket so and you can

really see the salt on the edge of that

you can see the soot in there and you

can see the slot in there so that will

all get scrubbed out with the wire brush

we're gonna put the wire brush it's just

this one well that's the big wire brush

she uses yep and when I remove the gauze

I will be able to clean don't that one

once I take the girls out right now with

yes I'm gonna take this and I'm gonna

shove it down inside between the gauze

on the wall and I'm gonna leave it of

the Gaza right until I can get a pair of

pointy nose pliers down in behind this

little gap but of me

yes hey let's have a look and you can

see all the soot buildup look it's solid

this is blocking the air hole right okay

when you put it in there's a seam you

see three spot welds all right okay

and that seam faces away from the air

hole all right so the air hole won't be

on this side the air who will be on the

exact opposite side which is here all

right and you can see this is clearly

where it comes in and it builds up all

this suit right and because the

measurements are same fine that soft is

just gonna cause all sorts of trouble

and havoc so I can I take my my brush

and I can start cleaning out this little

entryway well I'm also getting my hands

dirty because Beverly's handed me this

chunk of metal to clean let's have a

look now I haven't finished the idea

that's just some of the sort on the good

news front this is a standard m5 bolts

and it seems to fit seems to fit quite

nicely into those threads so I think

raaaah

I'll just get a couple of m5 bolts from

the Chandler's but it's quite clear that

this one here has had some sort of

thread insert kit put into it you can

see there's something in the thread hole

there and I suspect that's what that

self topicals into yeah but the main

thing from my point of view is bearing

up yeah so the main thing from our point

of view is that's gonna go and source

the nuts and I'm going to busily carry

on cleaning this so that when it's all

be nice and shiny for under the bolts

are too long I'll get some spacers good

good okay so this piece which I was

cleaning is done and this bit the verb

was cleaning is done Boston Timbers no

dough so each one of those we took half

an hour over better I took one half hour

and Bev took the off hours we've done

nothing with the control unit and the

motor right okay the motor well need

replacing at some

because it does but as you can see it's

a complete unit when you come to replace

that you unplug that throw it away get

the new one suck it in it's expensive

but it's easy to fix and that's the key

so thing to do you know is to put these

back together to open the kit and put

the gasket in yep

I also managed to acquire some bolts

okay so we've got some bolts tin steel

pan heads we are going to put those in

here

except for one of them which has been

reboard and fit it with a self tupper

now I've marked that one with a bit of

white paint so when I come to put it all

together I know which one to put the

self topper in to yeah so I don't mess

any of your threads up so can you open

this yes so I can see what's actually in

it this is the new glass screen okay

let's have a look at that

oh yes and there's that the goal

insertion tool that puts it in at the

right depth

so it's an exactly the right place by

the air hole right okay okay and these

are the two gaskets now this is the one

that completely got shredded yeah that's

because it gets very warm and it just

dissolved a newly other thing you need

to buy and you buy it separately is the

filter Hey look at that the two points

each okay so it's the green gasket first

yep you can't get the gaskets wrong

because they don't they're totally

different shapes and sizes so you can't

put them in the wrong you can say yeah I

can see that they're completely

different things

yeah right okay so that is where it goes

through two ways about it right so I've

got that I'm not gonna take my burner

unit make sure this little slide is

ready and I just drop that in on the

slide just goes it just goes here it

just fits

yeah like so so the deeds will troop

comes down between the screws right and

so you know that we're lined up and I

can see the white mark for the self

topper right okay so the machine screws

go at least three holes well okay so

let's go but these were the Torx bolts

but they're not just slots gross so next

time I will not need lead user talks to

yeah

but that's all done and now it's on to

the next bit next bit is to put the next

gasket on and put the motor back on top

that's it professor perfect so again it

only fits one way and you can see that

the shape here covers that little slide

yeah

so that will keep that in as well yes

but only fits one way so now it's just a

case putting the motor on that's the air

intake port icy air intake right here

it's a space for it to fit in right okay

so there's only one way around that can

go yep that must fit like so so got my

bolts I'm just gonna just before I put

him in it was gonna fit a little better

WD on yeah well she said tighten them up

by hand initially and now she's just

using the palsy drive to sort them out

again don't tighten them straight off

just get them loose in and then tighten

them up afterwards you get it when you

feel it simply not just give it about a

half or a quarter turn you don't need

any more than that otherwise you will

never ever get Amanda and don't use a

power drive because you will never ever

get a bun done you'll never get the

Montaigne's oh just a half turn extra is

all you need okay so now we've done that

it's time to back in okay keep

before we put the plug on we have to put

the guard screen in first okay so let's

look at the new Gore's

so as you can see it's all nice and

shiny and here you can see the joint I

don't know what's happening outside but

here you can see the joint and you see

three spot whales or three breezes they

have to go in facing away from the error

hall of the air hole is on this side

right so they will go fishing that way

right so answer tab under the little two

little tool then I just put it in there

I'll just push the tilt all the way down

as far as it goes and if you look down

inside you and I see that it's dying in

there and I be take the glow plug and

put the Google plug back in so we just

put this in very carefully and that

needs to screw in and like I say the

wires are very very stiff so you have to

that was it the three other felton yeah

so I put it in backwards and so I felt

the thread click and then as soon as I

got that I just rotate it by hand and

that soon as it feels like it's

tightening up I will use the tool on it

yeah but you have to keep those wires

with it because it is very stiff those

wires and of course

and hey it's got the point the wires are

coming back to where the control unit is

so I'm probably pretty close to be in

the right place this is feeling stiff

and now it's a little tool and the slot

is it's just perfect so that the wires

went there in all this so you don't

apply sideways force to that make sure

you keep this upright yep and then just

one little just tighten it slightly and

again don't over tighten no no Zee is

nice it's firm and now we're going to

put the boot over yes that's true

because good thinking about man thanks

so we're just going to cover that with

little boot once again the front screwed

overcomes and useful things in

yeah so as I say this is where we use

the flat screwdriver

although in future services will be

using that the check part of the machine

a partner

yeah but using it as a leaver more than

anything else that's not yen and that

means that this the brains this is not

coming back this will go back and just

slot it only fits one where you can put

it in the wrong way we took everything

back in wires will come up to there for

that a few seconds that's you just slot

and that's the little screw three it's

the little holding spray it doesn't have

any force whatsoever it just goes and

calls that at least now just putting the

temperature sensor back yeah and it just

goes in to place with this little it's

like a little hinge thing isn't it that

maybe I can never remember which way

round it goes

I suspect it has to go that way cuz it's

asymmetric again see alright okay

I know so that's going to go away and

Buzzy's going to have to put that in the

engine so where it goes in the transom

and then later on she'll put this filter

but we've got as you can see two spares
