I looked at a 1991 75 troopy this weekend and it brings up some questions as I know little about them beyond the cool factor.

Details on the truck are:
1HZ with a leaking injector pump, 326,000km (200k miles), 5 speed, no lockers, heat and AC that work, ARB with M12000, RHD, dual tanks.

The body and undercarriage are pristine for a 27 year old truck. There is a small section of surface rust on the rain gutter on one side, right at the calked seam, but there is no scale and it looks like it could be cleaned up with some sanding, phosphate, primer and touch up paint. No bubbles at all. There is no scale on the drivetrain/suspension/diffs at all. There is one very small dent at the ps tail light. It's a leaf spring truck with high pinion 8" up front. OME lift of about 2", 255 85/16 coopers on 5 factory steelies. The interior is spotless with a brand new looking vinyl floor mat, 60/40 bench up front, and a camp/drawer set up in the back with a bed, fridge slide, pull out stove drawer with utensil drawer. It has power to the back in the way of a 24v fridge connection and a USB charger. I saw no rust on the bottoms of the rear doors or anywhere for that matter.

The truck was cold when I arrived and the owner started it and it cranked instantly from a cold start- first turn of the key. Idle was good, revs sounded good.

Transmission held in gears, but there was some shake to the shifter when releasing the clutch, so I expect that'll need to be addressed soon.

So questions are:

the leak at the injector pump. It drips after running from somewhere near the top of the pump/ fuel lines. I could see exactly where. I've read and rear about rebuilds, resealing, etc. It needs to be fixed ASAP.

There are a couple Toyota shops around that I'll call today for an estimate, but with the similarity of the Denso pump to the Bosch VE, should any diesel shop be able to handle this work, or should I rely only on Toyota shops?

second, regarding the 200K, if the condition of the truck otherwise is any indication, the engine has been well cared for, however I don't know of service records. The truck was imported in 2016 from Tasmania.

What is the realistic risk of getting into this truck with those kind of miles? Driveline issues I can handle, but know nothing about diesels and I'm concerned about parts accessability. I've seen rebuild costs in the $6K range, and while a 1HDT swap would be ideal, it's not like they're at the local wrecking yard waiting for me to grab one for $500.

For the IP, Turbo Diesel and Electric Power Systems in Forest Park, GA. Talk to John in the diesel shop. He’ll take care of you for the IP.
 
Beno- thanks so much for the quick reply!

Man, you are truly nomadic! It seems that you're in a new location every time I see you post!! Weren't you just in Colorado?!
 
Odd Iron Off Road in Thomasville, GA is also an option for rebuilding your pump.
 
Most of the diesel shops will be more qualified to work on that ip then the Toyota specialists,as far as the mileage goes I have seen may 1HZ powered 7x and 80's driving around with double that mileage and they probably never had a rebuild before .One million KM's is not unrealistic as long as the drivetrain has had regular maintenance.With that mileage the output shaft on that H55 might have some wear but a gear with longer splines is available to fix that for not that much money.

At those klms its best to get a complete new gasket and seal kit installed, its about $500 in Australia. I would have thought any denso shop could do it ,but that often isn't the case. I would give it to someone recommended by Beno or Gun Runner.
Ask them if they have specific experience with this pump.


320000klms probably puts it about halfway or 2/3 of its lifespan. Most of them will show loss of power by 450kklms, but depending on how its been treated and how you treat it, it could go on for a lot longer. Its probably had a few owners in 27 years and you only need one to have abused it. There are a few in Australia with over a million klms.
They are top quality vehicles and you probably wont get too many unhappy surprises. You can get used to the 1HZ power, when you actually time how long it takes from point A to point B , its not much behind a car if you maintain legal speed limits.
Just don't expect it to go more than 2700rpm for long periods if you want the engine to last.

Funny thing is, I've been back and forth between a 911 and a 70 series. Two polar opposites in many ways, but they have a few things in common (door, wheels...), but it's really about enjoying the drive and while both are different, both are enjoyable to get behind the wheel and lay miles down.

There are only a few stretches of highway that I frequent and this wouldn't be my primary ride. My first truck was an 82 hilux 4x4 with a 4 speed. It didn't go anywhere fast, it just got there.
 
The 75 series show their best side on dirt roads at 80-90 klms an hour. I drove mine from Perth to Uluru (Ayres Rock) 2050klms each ,half of it dirt. The long range tanks, suspension etc just make sense. And another battery and you have a truly unique long distance vehicle that doesn't let you down.
The smashed up ones were from british tourists trying to go to fast. They have to have some kind of indoctrination now before they can rent them

@roscoFJ73 awesome pictures
 
I hear there are a few troopies in south GA/North FL that you might be able to go see. Im biased however. The above sounds good depending on price. Even one with a blown motor could be a steal for the right price. There is no such thing as a rust less 25 + year old vehicle. I would take a close look inside the body panels and inside the interior gutter. Another place it likes to rust is the windshield frame, but that cant be checked until you take the windscreen out.

I bought mine to drive. and i can do most of the work on it except gears and internals, its a very simple vehicle to maintain, unlike a 911 :-D Feel free to join the troopcarriers of america facebook page, we have a decent following, and its big brother troopcarriers of australia

Most importantly, lets see some pics!
 
serendipitous! @AndrewHadji - as I read your post about the facebook page, I'm watching a YT video of a couple that were applying their "Troopcarriers of Australia" decal on their 79 troopy.
 
If you’d like to take a look at mine, I’m in Decatur. It’s a 2H, but I can take you through the rest of it and try to convince you how great it is going slow. Just let me know.
