I welcome everyone! For a long time I was looking for information on the repair of the checkpoint, I did not find anything worthwhile. I decided to repair it on my own. The essence of the problem was that the third, and then the fourth gears began to turn on with a grinding noise. Tips and tricks are appreciated.
Photos will complement as the repair progresses.

Drained the oil. Here's what I found on the cork magnet.
Added after 38 minutes 6 seconds: Further disassembly, just like in the instruction manual:
I knocked out a finger of the gearshift ball mechanism with a punch, the sound of hammering a nail in a two-hundredth wheel. [img] https://my.housecope.com/wp-content/uploads/ext/2692/i523/1209/7. .jpg [/ img]
Hands somehow not very much, what came under the hands - a vice. I used the box body itself as a lever. [img] https://my.housecope.com/wp-content/uploads/ext/2725/i103/1209/f7. .jpg [/ img]
Added after 14 minutes 12 seconds:
He unscrewed, but not completely, two bolts from below (key for 13), unscrewed two bolts with an internal hexagon, removed the plate. [img] https://my.housecope.com/wp-content/uploads/ext/1886/1209/52/8c0. .jpg [/ img]
The bolt was unscrewed with an electric wrench, the shank was easily removed by hand. [img] https://my.housecope.com/wp-content/uploads/ext/1882/1209/3e/42c. .jpg [/ img]
Through a piece of wood I knocked on the front of the case with a hammer and the box fell into two parts. The primary shaft remained in the front, and the secondary, intermediate and shift forks in the rear. It was not difficult.

Mercedes Sprinter belongs to commercial vehicles that have proven themselves in Russian operating conditions. Reliability, convenience, ease of maintenance. But even the most reliable ones need service.The main treatment of Mercedes Sprinters, unlike other European commercial vehicles, is damage to the bearing shafts. Most often, the intermediate shaft of the gearbox suffers. In the photos below, the foreman indicates damage to the bearing seat on the shaft. Such damage is caused if you try not to pay attention to the resulting hum from the box. And attempts to solve this problem with various gear oil additives.

The Mercedes Sprinter model appeared in 1995, in 2013 the car underwent a serious restyling with an update of its appearance and technical characteristics. The updated version of the minibus is equipped with gasoline and diesel engines with various transmission options. A 6-speed manual transmission is provided for diesel engines, and a 6-speed automatic transmission for gasoline engines. The Mercedes Sprinter gearbox is highly reliable, the machine is designed for long-term use. In Russia, both cargo and passenger versions of a commercial vehicle are in demand.
A small video from the channel to allow you to get distracted from the problem of car repair:
Technical features of the gearbox
The Mercedes Sprinter model is equipped with a 6-speed manual gearbox G 16-5 / 4.898, it provides an optimal balance of dynamics and fuel consumption. The model is in demand due to its economy and reliability, "mechanics" guarantees the driver freedom of control and full control over the car.
The duration of operation directly depends on the quality of the lubricant used. For this model, the original oil from the manufacturer MB 235.10 is optimal; if necessary, it can be replaced with analogues 75W-80 or 75W-90, which were approved by the manufacturer. The recommended amount of oil is 2.2 liters, it should be changed every 100,000 km. With intensive use, the replacement interval is reduced to 60,000 km. When selecting the oil, it is necessary to take into account the recommendations of the manufacturer and the year of manufacture of the vehicle.
Minibuses of this brand are designed for 300,000 km or more, but their performance directly depends on the quality of service. Transmission malfunctions can occur due to aggressive driving style with incorrect mode switching, untimely oil change, as well as natural wear of components. It is important to identify the first signs of problems in time and contact the service to fix them.
Signs of malfunction of the manual transmission
Repair of a Mercedes Sprinter manual transmission is usually required no earlier than 100,000 km, but you need to be especially careful when buying a used car. If it has been used for a long time in conditions of constant city traffic jams, or if the previous owner was inattentive to maintenance, the risk of breakdowns increases significantly.
The following symptoms indicate faults in the manual transmission:
The appearance of extraneous sounds from the box during vehicle operation. Howling, crackling, crunching when shifting gears - all this indicates the wear of bearings and gears, they will soon need to be replaced.
Difficulty shifting gears. If it requires effort, or if the gear does not engage, this indicates worn out gears and gearshift mechanism. Defective parts need to be replaced urgently.
Inability to change gear while driving. For commercial passenger transport, this is especially dangerous, as the vehicle's controllability decreases.
Oil drips on the body, transmission fluid spots on the asphalt under the car. Oil leakage occurs due to a malfunction of the oil seals and must be repaired as soon as possible.
If the gear oil is not changed in time, metal shavings begin to accumulate in it, due to which the lubricant ceases to perform its functions.The increased friction accelerates the wear of the components, as a result, soon the box is completely out of order. To prevent this from happening, you need to contact the service center as soon as possible for a professional repair.
