Looks horrible at first glance but this is very typical for a old Soviet tractor that has no oil changes in many decades. I think the reason why one of the gears looks so worn is the slack in the spider gears. That is a very common T-25A problem and the reason is the bearings are just too weak from the factory. Also not made to pull very hard loads so that is also one way how to ruin your transmission for good. Some of the hydraulic filter disks look collapsed so you should get new ones when you do the next oil change. Also the oil is like a milkshake cause of moisture contamination from many decades. These hydraulic tanks do have a vent but it's usually not working at all. What I found with premade gaskets is sometimes you have to punch the holes larger cause some of them don't exactly fit. Hydraulic leak from the leaver pivots is super common but the cheapest fix. I think in the future you have to return and fix the differential. I know it's easy to say for me but before you take it apart. Make sure you have the parts already from a donor tractor and do the research. Other wise it's like you take it apart and find out there are no replacements anywhere. That is very typical for Harkov T-25 tractors. Thanks for the update video.

Steve my friend, you always have the best tips and advice thank you. didn't even know the tank has a vent actually. the spider gears have some weird washers pushing them in right? I should check that out sometime, also I think the transmission is so loud because some gears are more worn than others (some are from donor tractor already) is that possible?

@@nobodyha8760 One of your vents is on the transmission cover that small knob like thing. The hydraulic vent is on the filler cap, its a very small hole drilled on the side or in the center. They are most of the time plugged up with dirt. From what I can see from the video is one of the differential gears for the left side is toast. That can happen when there has been excessive bearing slack. So one side is moving closed to the spider gears and rubbing against them. If there are slack adjusting shims they might be just gone or incorrectly installed. That can cause misalignment. As for the crawling of the gears it might be to do uneven wear but also to do other factors. I would first invest into getting a good used differential with good spider gears and than replace the bearings also. Other wise all the hard work is for nothing.

O shit man, the gearbox looks like my mtz gearbox before it got rebulit. Very nice work!

Hell yeah, a new video! I discovered your channel about 2 years ago, and I’ve been hooked ever since. I've watched all your videos multiple times, and your content is so fun to watch. Keep up the good work!

@@Theredtractor hey thank you! Always great to hear supportive comments like that, really gives me motivation to make more videos.

On western tractors, gears have H pattern. On soviet tractor, gears have Ж pattern.

@@stevangucu522 I've watched some videos about old John Deere tractors, and they have some really confusing gear shifters to say the last... I'm sure it's not that but once you learn about it but to me they look very confusing, the russian tractors have pretty easy pattern. Just have to remember it because they're not in order at all.
