How do I determine the ROTATION of my Hydrostat? 1 All EATON hydrostats are stamped with either “CW” or “CCW” on the aluminum casting just below the Input Shaft. For example, if the unit you are sending is stamped with a “CW”, then you will need to order a “CW”. 2 Another way to tell is when facing the hydrostat from the side with the input shaft, look at the fan to determine what direction it must turn to blow air over the unit. If the fan must spin CCW to do this, then your unit is a CCW. We are here to help! The item “Complete Rebuild Service EATON MODEL 771 Hydrostatic Drive” is in sale since Tuesday, November 5, 2019.
