It can operate on flat ground decent enough but even simple black blading is dragging it down until it will stop. If we take steering out of the occasion it can't even back up inclines it could before. If I go from neutral to reverse with a steering break locked in the engine will rev down a small amount and nothing will happen. At full throttle I can backup and if I let it get up to speed first it will spin almost 180 degrees before it stops moving, I can release the steering break, let it start moving again and can usually pedal it 2 or 3 times to complete a turn. On flat ground it will move in reverse at just about anything over 1/4 throttle. I will definitely try to reseal those areas, seems straight forward enough. In looking over the valve body area it looks like it has several of these leaks that I need to fix, I'm hoping it's just a combined thing where I've finally just lost too much pressure with all these leaks. It will back up an incline and now it will almost turn 180 degrees before it bogs the motor down and stops, I can feather the break and get it to turn but it's still not right. The dozer seems like it improved about 75 % in reverse. I thought I would give it a try and see if it was the problem. This bolt was finger tight, I tightened it up and the leak stopped. I started the dozer and found quite a bit of oil coming out around one of the allen bolts on the left side directly in front of the shift linkage. I pulled the floor boards and found quite a bit of dried up oil on top of the valve body for the transmission. I pulled off the belly pan looking for a "Suction screen" that I've read is suppose to be by the drain bolt for the transmission. So no responses yet but I will update this as I go, hopefully someone with some knowledge on these things pops in. Any ideas? I have a manual and it looks like it's time to start checking pressure on the valve bodies? I'm hoping that one of you tell me it's something simple but I'm guessing it's not. I'm more of a "parts changer" than a mechanic but try to do most things on my own. Just seems like the clutch isn't grabbing good in reverse if I had to guess. Also it seems like the transmission oil is a little foamy / air bubbles when I check it. It SEEMS like it's a little better but still not right. I pulled the metal filter out, some minor crud and a small amount of metal flakes could be found. I can bury the blade and it will spin the tracks going forward. The dozer seems to be working fine in all forward gears. Hit a steering break and it stops dead in its tracks. ![]() Reverse will work on flat ground until the engines under a load. When checking it over today it was a little low on transmission oil but not bad, I topped it off with 30wt motor oil. I decided to let it cool down and wait until today to mess with it because it is about 20 degrees warmer out today. I put it in 1st and back to neutral a few times and then it would creep in reverse until the engine was under a load. This happened suddenlyl, I had been using the machine for about an hour then all the sudden no reverse. Yesterday while using the machine to clear some mud and yank out a stuck tractor it all the sudden wouldn't move in reverse. I had plans to work on it this winter when we're done with it for the season but here we are. I have always put about a gallon in it every 20 hours. ![]() I bought it knew it was using transmission fluid, I knowing the guy I purchased it from well and he told me it used it the entire time he owned it. ![]() I'm having a problem with my little d3b that's been a great little machine.
