Check the rubber bushings at the front of the crankshaft where the aluminum coupling connects to the hydraulic pump. Make sure the bolts are also tight as you dont want it flying off into your radiator!

Make sure to check the pump drive. If the coupler is loose or the bushings in the aluminum coupler are worn, it will be noisy untill a hydraulic function is activated, such as steering, 3pt, remotes. Also check the bolts that clamp the drive shaft to the pump shaft. If they are loose, you should also check the splines. Good luck!
