diesel service

[roscoFJ73]

I had my HZJ75 injectors rebuilt and flow matched ,pump tuned and adjusted on the dyno thursday.
The shop says they havent been done for about 100000klms which ties in with what the PO told me.
They said they were not too bad but the springs in the injectors were weak and the pump was turned up a little on the high side.

I told them I wanted it clean and economical so they turned it down.
They tuned it on the dyno to the max power without smoke at 1800 rpms.
It was getting about 61 hp at the rear wheels.
He said he always looks for 58-62 hp from a 1HZ under these conditions.

I cant honestly say I notice any difference,maybe it pulls better on the hills if anything.
I think my best economy in the HZJ75 is about 13.9litres/100klms (that big canvass canopy is worth a litre )
So Im hoping for an improvement this week

Sounds good rosco. I really like this idea of tuning on the dyno.,

Le's hope you get an improvement, either EGTS or fuel econo.

I hope so too,Im getting ready for a 7000klm trip to Alice Spring/Ayers Rock and back via the Central Hwy.

Highway is a bit of an exaggeration as its a really a 2500klms dirt road with 3 fuel stops and nothing in between.
My HZJ75 should do 1300klms between refills.

ILL probably have my brother coming along in his 96 Prado and he wants to do the Gunbarrel Highway as well. Its a series of dead straight roads built in the early 50 for chasing and retrieving British rockets launched from Woomera a few thousand klms away.
No maintenance has been done since on the 700 klmsIn fact much of it is detours around the original road as most of it has been washed away in floods.
Len Beadell engineer and surveyor who built the roads reported cabin temps in his 1953 landrover of 55 celcius

It wasnt all that bad to start with ,hardly any smoke and average economy.

Im trying to do things before they obviously need to be done and it just ticked over 201,000.
Injectors should be done every 100,000

My PO kept decent records since new. I had not seen injectors on them. So I think my injectors were original. At 230k when I did them I sure noticed an improvement. In fact the sound was so sharp(detonation) I thought something was wrong. But it wasn't. It was normal...

Looks like a fun trip.

Strange how your highways are soo rough. Is there not a lot of transport in the region?

Our trans Canada is super long through a lot of nothing, but since it is our blood line of goods it isn't bad at all. No dirt at all. All paved.

There is nothing out there to sustain a population.The centre only gets good rains on average of once every 4 years and it all comes in 1 or 2 days and floods the place.
Most of that area was not fully explored until the 50s. The central roads are there mainly to supply remote aboriginal communities. We'll be in the area where those 2 men died after there troopy broke down.
Of the 3 fuel stops I mentioned ,one is a mining town,one an Aboriginal community and the other is a meteorlogical station
The highways around the coastal areas are ok

Oh boy, hope y'll report back on this trip because my hope is to get to Ozi the next year or so and do CSR and Gunbarrel (and lots more).
It's all very premature and nothing is sure yet. But info is allways welcome...

Exploroz is where you meet all the long distance inland travellers. The site is also wealth of info for traveling all parts of oz.

Im still in the planning stages(I have 3 weeks) but each day it looks more likely.

Lots of links on google to CSR and Gunbarrel

Rosco,

You have to post a Thread when you get back from your trip. I think there would be a lot of people interested in the experence. My brother lives in Adelaide and I would love to see Ayers Rock on my next visit to Australia.

I thought most people made that adventure in the middle of winter? Isn't still pretty hot down under?

Back to Toyotas: What gear set do you have in your truck? Did the 75 series only come with the 4.10 gearset? Do you have any experience with the 1HZ and a 3.70 gearset?

Thanks

Frank

Its Autumn here since the 1st of March and the monsoonal rains should cease soon and the roads will dry out.
By mid April things will be cooling down in the outback. Ill take lots of pics

All aussie heavy duty 70 series had 4.11(pre 98 I think) I have 33 BFG and sometimes on the highway AT 110 -120 KPH I wish I had another gear but thats unloaded on flat ground.
I never use 1st gear except on very steep hills or in 4wd.

I think you want to tow a camper trailer and you were wondering what gear ratios. I think either would be ok but if you going into hilly country the 4.11 may be better.
I would go with whatever you have now and see what its like. Even if the 3.70 is a little high for 5th you will still have 4th. It cetainly wont be a disaster
One day I might try the 3.70 to satisfy my curiousity

On the news here this morning that a typhoon is moving into Oz approaching from the North-west.
Won't that spell disaster and undrivable roads?

Depends how far south the winds carry the rain. The cyclones turn into rain bearing depressions not long after they touch land.
Where the cyclones are crossing the coast is still a 1000+ klm from the Gunbarrel a If it does get flooded and doesnt dry up in time I will stick to the Central Hwy which is supposed to be an "all weather road"
But sometimes the rain travels all the way to coast of South Australia.
The main east/west highway was closed for a few days last month from flooding

That cyclone is the 2nd one this week,cyclone George killed 3 construction workers sheltering in portable accommodation at a minesite last Thursday.

Anyway we are taking Landcruisers not Landrovers

 

[Mickldo]

Sounds like a good trip Rosco

Definitely start a thread about your trip to show off the pics etc.

At the end of April I am doing a big trip like that myself. I plan on starting a thread on my trip too.

I am heading out to Birdsville, through the Simpson Desert, south to Lake Eyre (hopefully it will be full by then), down into the Flinder's Ranges, visit reles in Adelaide, over to Broken Hill, spectate at the ARB Warn Outback Challenge, Then head for home via White Cliffs and Hungerford.

I'll be travelling with some friends in their GQ Patrol Shorty rolleyes. I went to FNQ with them last year. We did the Bloomfield Track and the CREB Track together.

 

[roscoFJ73]

Well that sounds like a great trip too. I wish I had the time to keep going into QLD or Darwin

I'll be taking a month off work. The 28th of April will be my first day of holidays and I don't go back to work till the 28th of May.

When are you going on your trip?

 

[Ron R]

Do you (being 'locals' )think this time of the year to be the best for travelling routes like CSR - grunbarrel etc.
How about NT?

About our highways...

brownbear, where are you from?! Paved everywhere? Speak for yourself! Maybe in the civilized south and rich BC they are... Go north a bit from Montreal and west a bit from Ottawa and off the tourist trails and our 'paved' roads quickly turn into gravel!

As for roads not having been paved for many years... I wouln't say since the 50s, but we certainly have our share of potholed roads that weren't paved since the 60s and early 70s, as I am a witness to that! The last 3km or road to my house is worse than many trails in the carribbean islands... And people ask me where I 'wheel'... How many people have broken their suspensions, their exhausts and even lost complete wheels on that road!!! Then we get a little red flag byb the side of the road for a few months, until it turns into compost... then they come agin put a new flag in... That's their idea of 'road maintenance'!!!

A few years ago I had visitors from Europe that I brought to a nearby stream with a nice swimming hole, just a few km away... Of course, the road was gravelled like many around where I live (BTW those roads are in better shape than the asphalted ones for the simple reason that they get graded once a year), I never even thought anything about it, they told me how astonished they were by the 'third world conditions'...

Canada, apart from the belt near the US border, is pretty much like Rosco's Australia, except for the temperature, and sands (we have bogs and black flies in the bush)...

I live 80km north west from Montreal and to this day, just a few km away from where I live you can get seriously lost in the bush with (what do you expect) NO cell phone service to help you out (I need a Yagi antenna on my roof and an amplifier to get a cell phone signal in where I live).

Early April for 2 weeks ,WA school holidays

April onwards but July to October is best .Most of the northern half of oz will be mid 30s C or under without high humidity.This is their tourist season
Southern half will be in winter in June July August

Great, thanks Rosco

You'll have to keep an eye on the road conditions on ExplorOz. ATM all of the Simpson is still closed after the rains. I hope it opens in time for my trip at the end of April. Hopefully Lake Eyre will be full by the time we get there.
