The video walks through loader removal (and why he bothers), panel-off inspection of belts, air filter, and a noted hydraulic seepage, then the actual drain-and-fill using John Deere Plus-52 15W40 bought by the five-gallon bucket. Best for 4066R owners wanting a practical maintenance reference with honest commentary.
An owner-operator sharing a hands-on maintenance session from what appears to be their own property and shop.
The owner found he actually had closer to 200 hours between changes, which is the recommended change interval, not too long.
The owner removes the loader each time because the fittings and hoses are tight, making it easier to access everything for the oil change.
He uses John Deere Plus-52 15W40, which he buys by the five gallon bucket since it is more cost effective than gallon or quart containers.
The owner says there has been buildup near the hydraulic pump assembly since day one, and the dealer said that is pretty normal, nothing actively leaking.
