Thanks I would really appreciate any help I can get. The problem I'm troubleshooting is a drive problem. It seems to work ok until it warms up. Eventually it completely loses almost all drive power. I took some temp readings and the parker drive motor was about 10 degrees warmer than the main pump. I was able to get the drive motor out yesterday, no clips I just used some penetrating oil over night. I do sstill have the feeling that the main pump is the problem. I would rrally like to know what you did to fix it. The more info the better. You mentioned testing by capping the outputs to see if it stalls. If it stalls then the pump is working correctly right? Thanks again, anybody with a boboat bl or an earth force will appreciate this thread. I also a have mover problems in forward and reverse.
I am happy to help. What problem are you trying to solve?
If it is forward movement, then I suspect it is the hydrostatic pump as this was my issue and since my post I have been contacted by a few people with the same issue. Seems these B200 the pumps are too small and wear out in less than 1000 hours. I can expound on this if you think this may be the issue. I fixed mine and did some retro-fitting to help prevent this in the future. Simple check if the pump is working is to cap the output ports and the tractor should stall out if you actuate the forward/reverse direction.
If you are trying to get the parker drive motor out, I cannot help, as I was never able to get mine out. It turned out this was not the problem anyway, so I left it alone. It would seem there is a nut or clip or similar on the shaft keeping it in there, but short of breaking down the transfer case, I am not sure how one would get to such a clip. All the diagrams and advice I have gotten says there is no clip and it should just come out, but I could not get it out, ever! I was able to get the drive motor to move in the housing by removing all the bolts, but could never get it out or even loose. My point is that it is not bound or rusted in on the housing, there is something else holding it in there.
"Hi Greg, I was reading your thread an wondering if you were able to straighten it out. I'm battling the same thing right now. I'm at the point where I'm trying to pull the Parker drive motor and can't seem to get it all the way you. It seems there might be a nut on the end of the shaft. So just scouring the internet for information. Thanks"
