I have an early 1965 Case 450D that will not move. A little background for context of what was going on when this happened.
I was using the dozer when I threw a track. A couple of days later I had a mechanic from Pape come onsite to help me put the track back on. During the process of running the track on and trying to wedge the track back on, it seemed to bind up and the track would not rotate. The mechanic suggested that we check the transmission fluid level, and we found that it was low. My Case manual states to use TCH oil in tyranny, but mechanic said that we could use 30w regular oil and that they do it all the time. So we put 2 gallons of 30w in. After putting in the oil the track rotated enough that we were able to get the track on, but then the dozer would not move. That was September 2020.
I had in my mind that the ring gear had broken, because in the last 27 years it has broken twice before. So today April 29, I decided to take a look at it. After pulling off the floor boards, I saw that the driveline was spinning, and when put into gear, the shaft stopped spinning. When throttle was increased, the shaft still did not move, but it felt I was pushing against a big stump, rpm's down, and not going anywhere and tracks not turning. Changing from forward to reverse, I can see a little movement in both directions. And then it moved a couple of feet forward and backward. So, I thought that if the ring was broken, the driveline should be spinning all the time, so maybe it was OK and there was another problem. The dozer has moved only a couple of feet and has probably idled 30 minutes to an hour since the wrong oil was put in.
So now I am wondering if the 30w oil could be the problem, or just by coincidence the transmission filter is plugged or some other problem. Should I drain the transmission? Does the fluid in the converter also have to be changed? Change the filter? Does every ounce of 30w have to be removed? Is there just one Trans filter? Where are the drain plugs? Any ideas of other problems given my symptoms? Did the 30w destroy something?
Thanks!
