CAT 988G Hydraulic Pump Technical Know-How

The main hydraulic pump is an axial piston type, adjusting swash plate angle for variable displacement, supplying 20-32 MPa pressure oil for steering, lift and bucket circuits. During installation, ensure pump housing and flywheel housing concentricity ≤0.08 mm. Before first start, fill clean ISO 46 anti-wear hydraulic oil and rotate at 800 rpm for 3 minutes to bleed air, preventing dry-run wear.
