I have an MXM 155 with about 7000 hours for the last thousand or more hours we have had some serious steering issues. It is mainly obvious on the road but it came to a head on Saturday. I was driving down the highway and slowly veering into oncoming traffic, I knew it probably wouldn't steer so I started counting steering wheel revolutions, it took me 6 full revolutions before I started getting a response on the front wheels. This is mainly an issue on the road in the field there is enough steering going on that it seems like it keeps pressure better. It seems as if when you are not steering one side or the other loses pressure and then you need to make an aggressive jerk on the the steering wheel to get it to pressure up again and let you steer. It is just a whale to try to drive on the road, and I am afraid that someone could have a real bad accident since this is just happening all the time.
On Saturday I was baling and I even had issues staying on the windrow because I was just not getting steering response.
After I got home I checked the temperature on the transmission and the pump was at 200 degrees, and most of the transmission housing was 150-175 degrees.
This does not seem normal to me. We have had the dealer pressure test the steering and they seem to think it is fine as far as specs go, we have changed the steering motor in the steering column.
Any Ideas would be much appreciated.
My service lady at the dealer thinks maybe the pump is going and causing high temperature. Would high temperature be enough to make it stop steering normally? I know that the transmission has run HOT for quite awhile.
