Hi Tasos, awesome videos - all of them. I am trying to replace the transfer case bearings in my 722.9 4 Marco (2011 year with 160k km). I have figured out how to take everything apart and reassembling it - thanks to your videos. What I have no information on is how to shim or preload the bearing races to ensure there is no play between the output shafts... Mercedes will not offer advice and nobody knows anything on any forum. I am happy to pay for your advice....

Hello, thanks to your video I have cleaned my block + plate + solenoid valves. Thank you. On the other hand, I have a doubt. It was not so easy to put the whole thing back on the car. When I installed the set on the car I paid attention to the large electrical outlet & was able to finish but I did not pay attention to the plastic B3 tube. I inserted this tube correctly & perpendicularly to its place in the block (I did not mount this tube on the gearbox) solenoid valves. So when reassembling the assembly this tube was on the assembly that I was holding in my hands. From what I understand this tube is only used to tighten the clutch in first & seventh gear. I have been driving since Sunday I haven't noticed anything in particular. If I succeeded in assembling the whole, that is to say that the plug came out well & that I was able to correctly tighten the 9 screws of the block, is it possible that this B3 tube was not mounted correctly? If this tube would have been badly mounted can we understand it without disassembly in relation to the reactions of the car?

I'm going to do weistec upgrade eventually, only have 60K miles thus far. Also, common complaint is sticking downshift 1 solenoid, any issues/replacements from dealing with these?

very good video. I have a question, I have been working with a 722.9 gearbox for more than 1 month, I changed all the clutch discs with an international pressure master kit, everything new, the orings and rings are also new. I have a leak in the K2, the K2 clutch engages but loses pressure. Perform the test with air using the test holes indicated in the manual. Has it happened to anyone?

Probly too late on this reply but don't do it. More frictions don't do that much but will generate lots of extra heat. Line pressure is what primarily controls engagements.

Hello I am troubbleshooting my 722.9 // I found this piece of information in a forum but the image of the port layout wasn't accessible. "If you have the valve body out you can air pressure test the K1 by putting air to the hole in the trans case for K1" do you know how I could complete this test or have a picture of the port layout?

What was the point of this video? You didn't even mention opening and resealing all the servos. The clutches don't go bad unless there is an issue with the apply pressure caused by leaking servos or a fault with the valve body. The biggest issues with the 722.9 are the speed sensors and wear in the planetaries. There is rarely a need to replace clutches unless there is catastrophic damage.
