Jhawkins 43 #8 Posted February 8, 2022 It’s making a whining sound. The fluid is a clear golden color, the filter is correct. 1 Share this post Link to post Share on other sites

Pullstart 64,678 #11 Posted February 8, 2022 Is the hydro motor on the transmission clean? Does any noise change after the transmission is warmed up? Fluid level is where it should be? 2 Share this post Link to post Share on other sites
Jhawkins 43 #12 Posted February 8, 2022 Fluid is good and I don’t notice any noise from the rear end just from the lift 1 Share this post Link to post Share on other sites
Handy Don 13,355 #13 Posted February 8, 2022 (edited) The whine in Eaton-based hydro lifts that I've seen often comes from the relief valve. Once the lift cylinder has reached "end of travel" in either direction, the fluid pressure rises very quickly so to protect the pump that valve opens to allow the fluid to circulate around the lift cylinder. The very rapid flow of fluid can vibrate the valve and make quite a whine. The other source of whine is during a lift or drop and it comes from the control valve being opened only a small amount. Again--fast fluid vibrates the valve and ... whine! The valve on the 520-H's is part of the control valve. I don't know where it is on the 520xi. So the question is, is your lift whining during the lift/drop or at the end before you release the lever? Are you trying to feather the control?

Jhawkins 43 #14 Posted February 9, 2022 So it is when it reaches the top of lift and before I release the handle to stop lifting 2 Share this post Link to post Share on other sites

kpinnc 13,828 #22 Posted February 9, 2022 The manual for the 1100 say to allow up to 10 minutes run time in below freezing weather before actuating or damage may result. Not sure if that's meant to include hydraulics or not. My 520-H won't lift anything for 2-3 minutes after cranking, and that's in warm weather. It's the strongest Eaton tranny I've ever owned and it still does it. I'm guessing cold weather takes several minutes to prime and pressurize. 1 Share this post Link to post Share on other sites
