Kirstin & Vincent

We started with breakfast in front of the Swastika forest, just south from Tash-Bashat. Today we want to reach the Tesik-Kil, a 100 km track.

After some kilometers there are great viewpoints on Naryn river. Here we cross the max 10 ton bridge to Eki-Naryn.

We follow the smaller Naryn and after crossing the small steel bridge the Kichi-Naryn Gorge begins. A sometimes narrow track leads us through the beautiful canyon. The wooden bridges sometime scare us, what is the max weight of these? We tale it that the 10 ton sign at the first bridge is also for the other bridges. At times I want to turn around, scared that the road gets even worse when we continue up.

As soon as we get to Tamdy-Suu the road gets better and the view wider.

At the intersection there is the possibility to stay on the road back west to Naryn, we take a sharp turn east to continue our trip through the beautiful Balgart canyon.

An easy drive until we are just a kilometer away from our today’s destination. A landslide destroyed the track and we have to find a way through the stones and the river crossing.

We manage but is was not easy. This night we will stay at the start of our tomorrow 4-6 hour hike to lake Tesik-Kel.

At once the right rear wheel blocks for a short time and we hear a terrible metal sound.

We stop the truck on the road side and I check the oil in both portal axle housings and the differential.

The oil in the rear portal axle housing looks terrible. It is black and is full with metal filings.

We lift the wheel and notice that it can not be turned. After removing it we see one of the little brake cilinders is jammed and pressing the brakepad against the brake disk.

Kirstin removing the brake pad

We removed the lining from the brake pad so we can release the pressure and take out the brake pad. Now we can turn the wheel.

Our Unimog friend Unimog Donald advices us to block the brake by adding a bearing ball 5 mm in the oil hose, we did so we mounted the wheel again and tried driving but the loud noice was there right away again.

No internet

To find information about the Portal axle design and to ask for advice and talk to donald we need internet. Therefore we have to hitchhike to the main road, from Bishkek to Naryn. And after this we need to find a hike to Ottyk where there is cellular coverage.

When I arrived there the first time I found out there is a network, but not with my Beeline sim card. A Russian couple saw me standing at the roadside and asked if I needed help. They where so kind to buy me a Mega SIM card and di the whole registration process with their paspoort!!

The next couple of days we have to go through this driving and walking procedure at least once a day to get internet. One day I could not get a ride back so I walked and run this 26 km track over a 3.200 meter pass. Ppfff

Ruined Portal axle

A local mechanic where I bought this one bearing ball offered to drive me back to the Unimog. When he saw we could not drive he offered to help checking out the Portal axle. So we took it apart and where shocked by the damage.

The outer housing (partnumber 437 331 0105) is damaged. The bearing has worn out the housing.

Even the small portal gearwheel has broken gears. (total is 13 with part number 425 33607 / 10)

The large gear has 38 teeth and here is damage too.

Thru axle dismantling

When the thru axle is dismantled between the rear differential and the final delay, a lot of dirt comes out of the tube.

The little brake pistons are all scratched/oxidized, this probably caused the brake to jam.

Questions

The last 60.000 km we had some major damage in the drive train of our Unimog.

Some gears in the gearbox broke, the drive shaft between gearbox and differential broke and now the portal axle damage.

  • Am I a bad driver?
  • Can the oil be the cause?
  • Is it because the unimog is 30 years old (1994)
  • Is the Unimog not build for this kind of traveling?
  • We especially bought the 2150L38 because it is build for heavy duty. Are we to heavy with our 11 tons weight? This Unimog is build for 14 tons + 30 tons trailer, so tje drive train should be strong enough to handle that.

What we need

Unimog 2150L Unimog type 437 L38
VIN: WDB4371361W179982

The gears and the housing will be repaired in Bishkek.

The parts we need are:

On the axle (part 5) to the differential:

  • Bearing (incl oilseal) 362336B inside small gear
  • Bearing for outer side small gear in the housing inside 59 mm outside 88,9 mm

On the wheel “axle”

  • Nummer 74 metal ring
  • Number 72/71 oilseal 142,5 -175- 13/15
  • Large bearing (completely damaged) number unreadable
  • NUP312ECP/C3VE171 bearing + ring plates
  • Some very thin spacers inner 60 mm to mount the bearing

For housing

(Number inside housing Portal 4373513415 ??)

(number outside housing portal 437 3310105)

  • Seal for housing

Brakes

The little brake pistons are worn out. So we want to replace the complete pistons sets in and outside including the rubber seals.

Wakhan valley Pamir

The most impressive part of the Pamir for us was the Tajik Wakhan valley. This Wakhan valley is part of the corridor and our road follows the Pyanj river.

Instead of following the M41 east from Khorugh, the last change to get cash, do some serious shopping, get fuel and meet fellow travelers, we drove south. We found a great spot at 37.41544 71.49664 hidden in a rock formation.

We visited the famous Garm-Chashma Hot Spring. The men and women are allowed to use the outside “pool” at different times.

We passed the bridge at Ishkoshim which connects Tajikistan and Afghanistan and where every Saturday is a market where you can visit without a visa.

The interesting part of this part of the route started for us with a hike starting in Darshai, we hiked this gorge but turned around after some kilometers because the gravel and sand got in-stable due to landslides.

At the end of the afternoon we drove the steep and narrow road up to Bibi Fatime hot spring. An very nice, but as al hot spring here, inside spring. It is absolute worth the drive up. Here also men and women can use the pool separately. After this we drove down just a little to stay the night at 3.200 meters with a great view over the valley and to get adjusted to the height.

Zorkul valley

To add an extra road to our trip we planned at first on driving Zorkul. This route is joining the M41 at around 40 km south of Murghob.

Unfortunately we ate to early in the season, may/june, the roads are still impassable according guides we met in Khorugh. Khorugh is the place to buy the extra permit for Zorkul. We met a dutch couple who drove to the Zorkul lakes, which where still completely frozen, and the returned to the entrance at Khorgus checkpoint. But after watching their videos we decided it was to wet for our 11 ton campertruck so we decided to skip this part.

Bulunkul & Yashikul lake in Tajik National Park

After we passed the Khargush checkpoint, we where the 6th vehicle that passed today it was time for our real first mountain pass in Tajikistan, the Khargush pass 4.344 mtr. Because higher passes are coming we decided to camp 3.900 meter just after lake Churkurkul.

Since we did not see any shops and gasstations the last 100 km we decided the next morning to buy some bread and diesel in Bulunkul. But it turned out this coldest (-65 C) village in Tajikistan has no facilities whatsoever. Vincent baked later this day a bread in our little oven.

We continued our trip to two little geysers and had lunch here. Via a Yurt Camp with a hot spring we found our wildcamp at the eastern end of lake Yashikul. Fantastic.

The road to Alichur is impassable because of the very wet, swamplike, tracks so we decided to spend more time at lake Bulunkul and stay an extra night at lake Yashikul.

Tajik National Park

It is very large but quite expensive to be in. We pay with our truck € 40,- per day

We started Pamir (9. May 2024) in Dushanbe, Tajikistan and we take the south route via the Afghanistan, Pakistani and Chinese border. We expect to end this journey around 1.600 km and 4 weeks later in Osh, Kyrgyzstan.

Why now?

We are close 😂👍. The Pamir Highway should offer stunning views of the rugged Pamir Mountains and is considered one of the most beautiful and remote highways in the world. And the Pamir Highway is part of the ancient Silk Road, and has been used as a trade route for thousands of years, making it a fascinating journey. But, it can also be a challenging adventure, with narrow, winding roads, high altitudes, and harsh weather conditions. Traveling this route in May will give us hopefully the best chances of snow free roads and good weather.

Permits

Car, entry more then 5 days and per

It for Wakhan to be close at the Afghan border.

High altitude

Our Unimog truck on high altitude

Unimog is running okay but starting the truck at 10C and above 3.800 meters take some longer starting. After this a lot of smoke and ikt takes still at least a minute for the engine to run properly. To drive up the passes needs more effort amd we are ashamed for how bad the exhaust fumes are bluring out. But then, the diesel quality is also not guaranteed in Tajikistan, so this maybe a factor also. Our airtanks are back to 5 bar, normally they stay steady above 10 bar after one night sleeping and also filling the airtanks seem to take longer.

The aircilinder which switches from high to low gear has a hard time.

Tyre pressure …

Eberspacher diesel heater at high altitude

We do not use our diesel heater so much. We only used it above 3.800 meters to keep it cosy amd warm in the evening. I have the feeling it had some problems starting up, but it is running and keeping us comfortable. Also with the diesel heater the diesel quality might be an issue.

Preparing ourselves for high altitude

We are careful in picking our spots for the night.

Sleeping, sport, hikes. breathing while sleeping is more difficult then hiking.

What else happend at high altitude?

First our chips bags exploded around 2700 meter so we ste all of it 👍😂. The higher we came the more stuff “exploded” or made a mess when we opened them. The shampoo and sunblockers made a mess yoghurt put open while friving so our fridge was all over either it. At 3700 meter we woke up st night from an explosion. I did not want to go out to check out the damage but then we smelted something very strong. After some researching I found a little can with paint where the little blew off jjaacckkes.

We are stuck at the remains of the Aral Sea in Uzbekistan. We followed a much driven track in the sand but at once we break through this thin layer of sand/clay to land in the meters thick soft clay.

After a first try to get out the situation gets worse very quickly. I am afraid we might topple to the side or even worse the whole truck might just sink down in this clay.

Our travel friends Arnau, Ruben en Mathilde help us but after some days we decide we need help.

Because this seems to happen often here, to locals and tourist, there is a special rescue team.

They work hard to get us out and finally this works.

We wanted to drive from Iran to Kazachstan, Mangystau and Turkmenistan is then the country to pass. At this time, april 2024, you need a guide to accompany you and therefore we choose to travel together. Via Social we found Ruben and Mathilde, Traveling Scouts, who are willing to travel together.

The border crossing and how we got in is described here.

Although our guide was very nice he and we made a big mistake at planing this route. We drove 3578 km in only 6 days, which with our truck is impossible. We only had to hurry and drive till late at night and we hate doing that. The only good road in Turkmenistan is between Ashgabad and Turkmenbashy, the rest is pothole tarmac or just gravel or plain earth with lots of washboards.

And to be honest, the only things really worth visiting are the crazy city of Ashgabat and the Darvaza Gas Crater. The Kow Ata Cave and the Gochmyrat-Ahun Cemetery are nice to see, but if this was worth all the money and hectic…

We got stuck in the mud with our 11.000 kilo Unimog. Close to the beach we taught we had found the perfect spot to stay over night. But then we got stuck we had to enjoy this place for 2 days 😂

The government, the city of Emam Hasan at the Persian Gulf helped us we heavy machinery to get out. We are grateful for that.

Adding the bird-view to our journey’s and adventures was one of the reasons we started with Paragliding two years ago.
How special is it to fly over this World Heritage side: the White Terraces (natural travertine formations and hot pools) in Pamukkale and the ancient city Hierapolis.
We were really lucky with the weather: 20 degrees and wind from the good direction. Even when there are no thermal activities we are enjoying these short flights a lot, and starting several times from early in the morning until late in the afternoon.
Tandem flights are (next to ballooning) very popular here, so with the local pilots it’s easy to get a lift back up to the launch.

It’s also special to visit the site by foot, first the ancient city, the theater and old bath house, than barefoot the terraces and pools. There are groeps of tourist from all over the world but mainly Chinese. It is one of Turkey’s favorite destinations because of this natural beauty. .

Pamukkale, is a natural site in Denizli Province in southwestern Turkey. The area is famous for a carbonate mineral left by the flowing of thermal spring water.
The surface of the shimmering, snow-white limestone, shaped over millennia by calcite-rich springs, dripping slowly down the mountainside, mineral-rich waters collect in and cascade down the mineral terraces, into pools below. Splendid.

On the top of the travertine formation the ancient Greek city of Hierapolis was built. The first buildings on the site of Hierapolis appeared in the 2nd millennium BC. One of the most important sights is an ancient theater that is located on the hillside, the overall height of its steps is about one hundred meters.


Hierapolis was famous for its thermal springs and became a healing centre where doctors used the thermal springs as a treatment for their patients.
You still can visit the thermal springs, so we took our swimwear and enjoying the 37 degrees warm water.
