I have a D-31E-17 Komatsu dozer 2600 hours original owner. We never changed the trans oil and screen. So I decided it’s time. I drained bevel gear case both final drives and steering cases. I removed the screen in the trans and cleaned it,wasn’t very dirty. I put it all back together and filled to all the dipstick marks and now the machine won’t move forward or reverse. No whining surging or anything. The one thing I don’t remember is the screen orientation. I put the open end in first, I don’t remember how it came out. I don’t know if it will go in either way. Does anyone have an exploded view of the trans or any other insight? My father is rolling in his grave because he was one of those don’t mess with an old transmission guys. The machine worked perfectly before I did this! All the linkages work going into trans. Thanks
