Hey Roman
Im still grounded, two weeks tomorrow and the belly is getting smaller cause
I have discovered that i have legs and when you move one in front of the
other and so on you can still get places but slower than in the cruiser.
They took the injector pump out this morning and thats all i know.
They were too busy to go near it before that.
So it would seem to be a problem with the injector pump which I am really
interested to find out what, as they were the guys who reconditioned it four
years ago and I do use my Millers.

Hi Guys
Been on the phone to the Diesel guys and they wont know whats wrong untill
maybe next Tuesday.
They wanted to know the symptons ,which i explained to them.
He said there is no power going to the injector pump so most likely a wiring
problem.
But because of the symptoms which I described to him , he thinks that is a
pump problem.
So maybe a double wammy to add to my cruiser luck.
They said they could get it to start but not run, the guy I talked to before
said he had the pump out , this guy says he is taking it out and needs a
puller ( i think) to take the pump apart which they dont have.
I dont know what he means.
He did say that there is now no power going to the solinoid at all and when
I told him we had power all the time even with the keys out he said that
should not happen.
He discounted the posibility of it being a problem with the solinoid at all
as he said this just does what it told to do.
I asked him would he fit the Walbro that i put in the boot on the off chance
he would.
They wont toutch it as its not in their scoop and will only keep to what
they do.
So I still have a Walbro and even the Diesel experts wont fit it for me.

Hi Guys
Just another update for all of you who have a clue what I am going to try
and explain.
I think for the mechanically minded you may know what the hell im talking
about, but for people like me its just too much gobblti gup.
Now please bear with me while I try to explain after his technical overload
of information.
The problem with the cruiser that led to the breakdown was indeed the
injector pump going ga ga.
The delay in getting to this point of actually knowing what was wrong was
that he needed a puller tool to get the pump off of the engine, something to
do with gears or cogs I think.
Anyway he neede this tool and he had to have it make specially for the
cruiser.
So I guess that he does no work on cruisers like the VX and every
aplication is different from truck to truck to car or digger etc.
He says the problem was a part inside the injector pump which
regulates the flow of fuel in very cold conditions by advancing the timing a
bit to help compensate for the cold.
I asked him a few questions just cause I do and this is what he said.
Its a small part that acts like a valve which is spring loaded and this
actually broke off and went around the injector pump and lodged.
He recomends or is going to bypass this part altogether as I dont need it at
all .
I asked about the cold starting and I heard a little chuckle and he said
that we dont need this at all and it would only be of use in the Artic
climate or places like norway etc.
He did say if I wanted he could order a new assemble for the pump which
could be expensive and would have to come from Japan.
He reasurred me several times with the same words ( you dont need this part
unless you are going to live/travel to very cold climates).
So to find out that I have a part in the pump which I dont need that broke
because of age and nothing else will cost me dearly.
He explained that when they make the vx (top of the range) back then Toyota
were fiddling with all sorts of devices to make the cruisers more able to
deal with all sorts of climates.
And its only after this pump spec that electronic pumps were and are the
bees knees.
So who says education is cheap
Maybe if I have it wrong someone on the list can set me straight, would not
be the forst time.
cheers

Hi John

I am sure Julian will tell you in more detail but to my knowledge the cold start system is outside the pump. The idea is that there is a wax filled cylinder that pushes against a lever that is part of the linkage to the throttle cable and when cold it moves and makes the pump squirt in more fuel till the heat stops it from doing this. I guess?? My diesel man explained it to me so I may have got it completely wrong. also I don't like all this talk of special pullers etc. My guy had no issues with pulling off the pump he had all the tools there, big hammer, big spanner, even bigger hammer, chisel etc. But seriously all he does is pull off pumps and fix them. The only thing that stopped him was my lack of money! Is there anyone else near you that can look at it??

I just had a look in my book and I could find nothing like you described inside the pump. Julian has a very good firm near him. Maybe pull the pump and send it to them to be rebuilt?

Good luck

Simon

Hi Simon
He has it and will finish the job, ill get the bill, try to find out what he
did or said he did and be completly happy. He did say he has at some stage
taken pumps off with the aid of hammers and such but that its not really the
thing to do, and thats why he waited for this puller thingy thing to be
made.

Hi John,
[email protected]#dy Hell is every beggar in the service industry out to get you. You
mentioned he is the same guy who serviced your pump during the rebuild
of the engine. Why the hell did he not remove the cold start advance
ball and throw it away when he serviced it last time if it was coming
loose (they take a while to fail).
The mechanism you describe is indeed a wax pellet activated cold start
device, you can see some of what it does from the outside it lifts the
throttle arm off the normal idle stop so that the fuel injected is more
than hot idle to help lift the cold idle speed, it also has a shaft that
goes inside the injection pump with a ball rivited and welded to the end
this ball is on an ecentric. As the shaft turns it pushes on the same
component the advance piston actuates so that it advances the injection
timing as well to allow for the longer ignition lag when the car is
cold. It is common in the diesel industry here to remove the cold start
mechanism and cut the ball off.
Why did it fail? Two reasons the wax pellet (that is exposed to engine
water to make it expand and contract) may have collapsed and or the pump
maybe sucking air in through the front seal. Why would that matter? As
the engine revs the pressure inside the pump rises and this advances the
injection timing if the pump is struggling for fuel it will suck air in
the front seal or may cavitate on the internal feed pump when it does it
suddenly loses body pressure and the advance piston swing's back to idle
position and hits the cold start advance ball if it does this often
enough the cold start ball will fail via a fatigue failure and fall into
the pump usually causing catastrophic injection pump failure. If you run
a Walbro pusher pump the injection pump is alway's force fed with fuel
and this is much less likely to occur (the wax pellet could collapse
still but that is quite rare). If running a pusher pump I have no
worries about the ball coming off but in a hot climate without a pusher
I would remove the ball.
The engine will run quite happily without the ACSD (automatic cold start
device) some NZ new cruiser came with it some did not as far as I know
all Australian trucks were never fitted with it.
John get an estimate of repair cost as generally this failure destroy's
the injection pump beyond repair. You maybe better off buying a brand
new injection pump off Maarten in the Netherlands.
Regards,
Craig.

Hey Craig
Thanks for the info on me little problem.
I knew some one would be able to make out what i said.
Ok ill phone marteen and see what the cost of a pump is and then phone this
guy and see what he says.
But really he gave me no indecation of the pump being knackered at all.
He did give me the impression of it being just a case of of fixing this
leaving out this spring loaded part, putting the pump back to gether and
away I go on my merry way back home and him to his bank with my money.
Now break it to me gently, is there any thing that I could have done that
would have caused this failure or was it just my lack of luck.
He did say the pumps are strong ones, but this rings hallow when you
concider this strong pump has failed twice in four years.
Its like when I hear stuff like Landcruisers last forever, they do if you
have luck or what ever on your side and if you dont well you just need to
keep ploughing cash into it.
Ah im pissed off with the thing.
cheers

Hi John
I just want to comfort you and assure you are not alone-many guys
believe (or want to believe) in those fairtailes Cruisers last
forever-of course they don't and if you are unlucky then you go
through nightmares hardly to describe: I had LJ70 87 model and put in
it more than 100000 Norwegian kronas
but still it did not become perfect-at the end I got fed up and sold
it for 50000. But the guy who bought it vas very happy and said he
will make it perfect
-well I wished him all the best and hope he did it -that's how
Cruisers go and go....I bet every one of us here on the list has more
or less invest
in the 'legendary HDJ80' more than expected amount of money but
that's how it goes: if you buy a 'new' car you don't repair it but
you loose the value...
and the other way around is what we do-buy some old LC and then begin
to invest until you deside to quit it one day and then buy something
else and the story repeat itself......
Sorry if I was wrong....
cheers
Lubo(invest already 1/3rd in my LC and still not so happy...)

Hi John,
Other than having the ball cut off or running a walbro pusher nothing
really nothing to prevent it happening. As far as causing it goes you
didn't. You are in Ireland I thought there were meant to lots of little
green leprechauns helping out or do they just cause mischief.
Cheers,
Craig.

Hi Guys
I was on the phone to the Diesel guy about the injector pump and he told me
that the pump is fine and will be going back on the cruiser later today and
then as he says , its all testing to make sure everything is ok.
I asked for an extamate of cost and he could not give me any untill its
finished and the job card is presented to him..
So ill have to wait and see.
He did tell me (as Craig had said previously) that usually when this ball
bearing gets lose it completly destroys the pump and you then need to buy a
new one.
In my case it did not do any damage at all to the pump.
He said somtimes the ball gets lose and will do a lot of damege before the
vehicle actually stops working, but by that stage its usually too late for
the pump.
In my case it stoped the vehicle from working and so saved the pump.
One of these weird things again or is it as Craig says the little
leprechauns at it again.
cheers
