I would suggest everyone check the hydraustatic drive circuit on your CR90*0 filter to ensure the the filter housing is installed correctly. Our filter housing was installed backwards, forcing oil through the filter inside out, and preventing the bypass from opening in the event of a surge or filter restriction. Our filter was installed backwards, the filter failed, and filled the entire hydrostat with filter material. The arrow on the filter housing should face the front of the combine. Took an entire day to clean the control head and orfices in the charge pump.
