Bone quite a few of troopys do overturn in the aussie outback,but its really a matter of driving,weight distrubution,tyre inflation and often alcahol

Also in remote areas LWB 75 series are well and truly over represented,distorting the stats,hell your not going to see a Honda CRV out there

The flywheel I would leave until it needs a new clutch ,giving you time to research it more.
A single piece flywheel is probably better but I too have not heard of the Patrol having trouble with their setup

Thanks RaoscoFJ73,

I previously asked about oil adsditives - have used the American product STP -but sure there are many products out there. I will simplify my question. Should one just buy good quality oil that do not rerquire additives (some brands claim to have additives pre-mixed already) or treat your engine the way you want.

I must add that I have extremely pleased with additives on gasoline engines (at 25 deg Celsius all year round) as you considerably increase the service time with minimal loss of viscosity. Quite pleased!

Much appreciation as always,

Bone.

Theres always lot of opinions on additives and this is mine
I say use a good oil/filters and change as per the recommended schedule.

I heard of plenty of owners who swear by additives and the manufacturers offer plenty of guarantees but they always seem short on independant,correctly audited scientific proof (show me some if someone has it).

Ive also never seen a car maker or oil company approve them for use with their products, but I have an open mind

The troopies flop easily because of all the glass and metal placed high up on the vehicle. Does the 75 ute have the same tendency, Ross? The 77 may also have the same liability. Wider wheels or wheels with a more negative offset/less backspacing might be the answer. There, I just gave Bone a reason to upgrade to bigger tires

Has anybody heard of a one piece flywheel for the 1PZ? There may be some design reason it is a 2 piece, or Toyota would have kept it one piece, the same as the others.

Beanz I suspect the troopy would roll over easier than the traytop but statistics are hard to come by.
I think Monash University did some research but said it was inconclusive
Maybe the SWB BJ70 would be worse than the LWB 75. The shorty's can be a handfull going round bends on corrugated dirt roads

Many of the rollovers involving 75 series happen in remote Aboriginal communities and cattle stations from a combination of stray cattle,bad roads,burst tyres ,alcohol and from competing with road trains.

Unless there is a reliable witness, its fairly difficult for the cops to work out exactly what happened.
Its always easier to say you swerved to avoid hitting a camel than admit you were going to fast with a gutfull of piss

Mining and other companies in remote areas can no longer get insurance for workers transferring from one site to another after dark.


There is also the problem of hire companies renting 75 troopys and hiluxes to tourists who have never driven on dirt roads or deserts tracks before.
A little off subject but only last week a Japanese tourist drove to Mt Augusta in a hirelux in 115F heat and was found dead a 1klm from the car as he attempted to climb the big rock alone with no water.


I dont believe any experienced owner who loads his vehicle properly and takes all the right precautions will ever have a problem.
Some city folk can only imagine doing a 5 desert trek at 60 mph non stop with every conceivable home luxury loaded into the back

Heheheh, a Hire - lux. I like that.

Wayne, Dave, roscoFJ73 and all tech-oriented members,

When someone is off-loading the the PZJ engine to change the timing belt, what else can be changed at the same time?

I am still thinking about the flywheel stuff discussed before. Could it be possible to take a look at the clutch this time? I do not have any drawings at hand but was assuming that the gear box is going to be separated before off-loading the engine?

I am also told that the AC + fan belts, as well as the power-steering belt could also be replaced at the same time. What else could be fixed at this time?

Will appreciate your input as always,

Bone

 

[crushers]

unless i am really missing something here, there should be no reason to pull the engine (as assume this is what you mean by off-loading) to change the timeing belt. the belt is on the front of the engine...
i would not worry about the flywheel till it comes time to actually change it out...
as Dad use to say, "if it ain't broken don't fix it"...
cheers

 

[beanz2]

There is a tensioner spring on the timing belt idler that Toyota recommends you to check. It is only US$6 at the dealer (90507-27003), so you might as well as replace it.

Dave and colleagues,

You guys never cease to amuse me with your attention to details! Thanks.

Dave mentioned previously that you recommend big tyres instead of the current 16". I read a warning from Toyota which discourages higher ground clearance as it increases, yes, increases the centre of gravity and hence the risk of a roll-over. Same applies to heavy load on the roof carrier.

Bone

 

[crushers]

what i have found is you can have a high COG but you need to drive accordingly. you do not drive a Land Cruiser the same way you drive a civic. you do not drive a SOA the same as a SUA. we have a gent here in Calgary with a roof top carrier and 2 of those flip up roof top tents on his lifted BJ46 and he has not laid it on the side.
driving style is more important than truck design, in my books anyway...
cheers

This is all true but if your going wider(tyres) it partly cancels it out.
I believe the wider and slightly higher 33 in make them handle better over the stock tyres

The 33 in tyres would only lift it an inch above stock anyway.

They are at their most unstable in sand dunes where speed is required to sand surf and you are following someone elses tracks.
The tracks start off straight but get chicanes in them which cause you to swerve violently from side to side(making the track worse for those behind).
Because the tyres cant slide sideways in the ruts it tends to throw the top half around.

Bone you got the wrong sort of motor if you want to play around with it each weekend.

Once the 1HZ/1PZ are serviced and running right there's nothing to do except wait for the next service.
Maybe get yourself a 1971 Norton Commando to rebuild each weekend between cruiser services

Hmmm, I did? I did it with mine just because I like the looks It killed the engine's performance, but as Wayne said, the wider tires made it up somewhat with the wider stance.

Crusher, do you still by chance happen to have the manual for this vehicle?

I've just been offered one down in Chile and since I was trying to find a diesel 70 series (looking for a troopy) someone has offered me their PZJ77 for 13k USD. Is this out to lunch? I need to get pics and actually inspect it from top to bottom, but I'm looking for a cruiser to 'go deep' in a trans-amazon expedition from Venezuela to Chile. My thought line is to buy in Chile and not get mixed up in the papers/importing to Chile once the trip is finished and the vehicle will live there on our ranch (also soon to be bought/built). The engine has 200k km on it and has reportedly just finished an 11kkm trip through patagonia. Anyone have a thought about this condition? Would this be something worthy of upgrading to a 1HD or KZ engine (if I can find one)? Having 4 doors is close runner up to getting a troopy and this one could carry the kiddos (not in the amazon though...gents only trip you must understand). Vehicle is a '92.

We got free online manuals for the 1PZ 1HZ at the top of the forum.

With 200k ,I would give it a compression test and if ok ,add a turbo.
It would be equal or better than a 1KZ-T
If you use a 1HZ or 1HD T,you probably need a gearbox swap also.
That mileage is not high if they have been serviced reguarly.
Put a roof rack on it and it would have the same storage space as troopy w/o roof rack
Its a good choice of vehicle for your trip
The 4dr wagons are not such a common model in the heavy duty 70 series,but much prized.
You will have some jealous friends

 

[crushers]

i would take a PZ over a KZ at the drop of a hat...

i have fallen in love with that little 5 cyl.

yes, i have the manuals sitting here ready to ship but as Rosco says you can down load them for free...
