80 Series with factory part time 4wd (1 Viewer)

[Zach R 86]

Looking at buying a 97, 5sd, 1hz, rear ambulance doors, 10 seater (60/40 front seat for 3, bench seats for 4 in the way back rather then the normal 3rd row. Pretty unique from what I’ve read/seen. The owner doesn’t know a ton about it, but did confirm it came with manual hubs. So that means factory part time 4wd too correct? My question is with that setup. Do I have the best of both worlds? Can I leave it in 4H with hubs locked and have it drive exactly like my US full time 4wd 80? Or do these hubs need to be disengaged at higher speeds / pavement. It has a “4WD” label on the back, not the “FULL TIME 4WD”

You can lock the hubs and drive in 4wd, that is how it is meant to be used. No need to do that though on pavement, especially in CR.

The truck is not full time 4wd.

5spd should have the hf1a xfer case something like that will have 2h-4h-n-4l on shifter where the hf2a on us spec is full time trans probably h15xx

With manual hubs, you can leave them locked on the road while running in 2-wheel drive. Simply back off the throttle a litle and shift to 4-Hi as needed.

Going to 4-Low requires a full stop unless your real tricky at very low speeds in order to speed match the 2 to 1 differnce between input and outrput. Highly recommended to just stop and engage.

Thanks so much! Sorry for my ignorance on this but one more question. If I were to just leave the hubs locked and the transfer case in 4h, would it behave exactly like a us spec full time 4wd? No issues going highway speed on pavement locked and in 4wd? I’m not saying I want to do this but we have a river crossing 5 minutes from our house that we have to cross every time we go anywhere and it’s easy to forget to disengage one or both on the times we do go out on pavement and drive highway speed. This would be especially handy when a friend or my wife uses the vehicle that is not familiar with hubs and/or 4wd transfer cases. If I could just send them off in 4wd with hubs locked and not need to worry about what driving they do... I just know my 88 Hilux lurches on pavement in 4wd & locked. And am I correct that manual hubs are not designed for highway speed? Been inside mine a million times cleaning then and re-greasing and they seem simple enough, but I remember reading that. thanks guys!!!

It will act like your hilux, shouldn’t be in 4wd hubs locked on dry pavement.

Perfect, thanks!

Perfect, thanks!

It is NOT an ALL WHEEL DRIVE like the common USA models.

No, it's not the same as film time 4wd.
Full time has a differential in the transfer case so the front and rear driveshafts can rotate at different speeds as you go around corners.
Part time 4wd has a solid spool in the transfer case, no diff. Driving with hubs locked in 4H on dry pavement will cause excessive load on the drive train, and can cause wheels to break traction cornering

Pics or fail! C'mon!

Let's see this thing!

Thats perfect, thanks! Right, I figured there was something different in the transfer case allowing full time cruisers to spin at different speeds, unless in 4L i think.

Just the photos the guy had in his ad. We have locked down a deal so as soon as he returns to the country later this month I will go pick it up if the condition is what he has described. 220k on a 1hz should be fine from what ive heard.

I confirm what Mudgudgeon , is saying.
It's the same system that 1HZ African version have .
On asfalt you can run with H2
On slippery ground , or gravel engage H4,or L4.
The gearbox/transfer . Doesn't have a differential, that's the reason you can drive it 4WD on asfalt.
Especially in tight corners , you will come to block the steering or the car .

 

[mudgudgeon]

Provided it's had basic maintenance such as oil and filters changed, 200k km on a 1HZ is the run in period. With love, it should be good for triple that

 

[LandCruiserPhil]

It also has the cut out in the lower dash on the right of the steering wheel for the factory PTO winch.

 

[bicycleagent003]

That's a sweet rig! I know many on this board love the drop down, split rear doors of the US spec 80 series, but I also see the utility and coolness of the ambulance doors. I also love that you're getting an OEM rear tire carrier. The specs and pics looks great, I think that's a total score! Well done!

If you forget to shift the TC to 2H on pavement, you may feel the truick acting differently enough - especially through curves - that you'd realize it needs to come out of 4H that it will remind yoiu. That said, a few minutes on the pavement in 4H shouldn't be a big deal, althoughj you want to avoid it.

I especially like the climbing loops going up the left rear corner to access the roof rack.. I recall seeing them on some Middle East spec triucks before, but not in the Western Hemisphere. I don't need any, but others might be curious about the source. When you get the truck check to see if there's any identifying marks on those for thiose who might be interested.

Yeah, I am familiar with the feeling of 4wd on pavement from my jeeps in the past and current Hilux, thanks. Sure will check for identifying marks on those steps.

Same as about any other Land Cruiser model with lock-out (Free Wheel) hubs.
In H4 you can drive it on pavement, just different/stiffer steering feel (plows through corners), more rumble/vibration from the front axle components turning.

The owners manual should tell you to regularly (once a month?) drive
a bit with the manual hubs engaged and in H4 to keep the moving parts lubricated, but you should not drive it in H4 with the manual hubs disengaged (free wheeling). The owners manual (if the seller still has it) should mention all that.
