Awesome build & some spectacular driving locations too, keep it coming & welcome to ih8mud. I also have a 70 series with that PTO winch & 36" Simexs, they certainly get you places but portal axles is definitely taking it to the next level.

Looking through your first pics of the portal axle install I was thinking 'I wonder if you need some sort of traction bar to stop excess torque on the springs' ... looks like it does

Cheers
Clint

May be you are right! But this time the problem was solved by return from parabolic leafsprings to original multi-leaf springs

BTW, rear leafsprings at PZJ77 are the sama as new HZJ76 (2008-....) Friends sent to me a small box with suspension kit :rofl:

So, after Mongolia we started to plow mud at home, Western Siberia.

Do you know the main portals problem? It's ground clearance depth

Front winch is not enough. And we decide to install rear winch. Instead of rear stuff box. ComeUP 9000 24V
And also rear bumper with spare wheel

That summer 2012 we took a great offroad trip to North Ural mountains. 4 trucks, 3 weeks.

Lapocruiser · Mar 27, 2020

This extreme way became a full-blown hard test for portal axles. And for whole trucks and people too

Lapocruiser · Mar 27, 2020

We moved along the slope of Ural mountain range. The average speed 20-30 km a day
Rocks, mud, swamp, deep tracks and angry wild trees!

Lapocruiser · Mar 27, 2020

Certainly we got a damages, but my TLC was OK all the trip

Living the life some of us dream to live.

Love it!!

Lapocruiser · Mar 28, 2020

Thanks, guys!

So, we moved throw Dyatlov pass to the famous place - mountain plateau Manpupuner. We climbed to Chistop mountain with destroyed radar station.
All these places are not available for common trucks. Only for 35' and higher

And of course portals are better way to drive there

My TLC77 made me absolutely happy at this trip. Only one thing bothered me.

We drowe about 5000 km on highways.
Siberian highways are not the same as US

It's narrow, only 2 lanes.
Overtaking became a problem, when maingear is 6:1 and the engine is 1PZ
This 5-cyl diesel 3.5 litres without charge is good in swamp. But when you decide to overtake someone on the road.... :bang:

Yes. The next point - engine swap!

Lapocruiser · Mar 28, 2020

The engine must be also oldschool. It should be diesel without any electronic control. 6 сyls with turbo.
I choose 1HD-T. 165 Hp and 365 N*m at 1800 rpm

GTSSportCoupe · Mar 28, 2020

Really enjoying the photos and story! Keep it coming!

Lapocruiser · Mar 28, 2020

Keeping coming, yep!

The original gearbox was R151F. It's OK for 1PZ, but too weak for 1HDT
There are 2 suitable gearboxes - H150F and H151F I choose first one because it has lower 1st and 2nd gears, better for offroad
Clutch also were removed. I had fo buy a new 300 mm flywheel instead of 250 mm old one. And 300 mm ISUZU cluth disc, suitable for H150F with 21 slots

Volvo portals has no hub locks. So there are no reasons to keep patr-time transmission.

I believe transfer case with differential is better than none-differential

So we use the same transmission as Lamd Cruiser 80. Full-time with electric difflock.
It also has better lower gear - 2.38:1

Only one thing was hard - to find transfer case with PTO. But we found it. Some of Generel Area 80s also has PTO winches.
BTW, 80s PTO looks a little better than 70s

10 mount bolts and better lever lock
