S Series Geroler Motor, 22.70 cu in/rev, 4 Bolt Mounting Flange, 1 in. Straight Keyed Shaft, Manifold Ports, Compact yet powerful|Extended bearing life|Increased shaft seal

Manifold ports are what this motor is set up for, and the port style is called out as manifold ports with .3125-18 UNC-2B mounting holes. It is meant to bolt up to a manifold, not plumbed with typical hose ports.

Premium quality anti-wear hydraulic fluid is exactly what this motor calls for. Fluid viscosity should be around 70 SUS at operating temperature, so as long as your hydraulic fluid meets that and carries good anti-wear properties, you're in good shape. Also worth keeping your system filtration clean, the recommended cleanliness level is ISO 18/13, which keeps internal wear down over time.
