4625sx Eaton 70344 Hydrostatic pump Trunnion/Control Shaft seal leaking. In a post on the Bobcat Forum - post number 20417 , they refer to o-rings on the shaft. I have replaced the Trunnion Seal, located at the top of the shaft, but still have a leak. Does the shaft on my pump have those o-rings that I can not see until I remove the shaft? How do I remove the shaft? ps. I've updated my profile to free html per the FAQ, but can not get the HTML to work. Have tried Explorer, Chrome and Firefox - all no joy on the html.
