Professional Service Insight
When overhauling New Holland Bale Wagon hydraulics, absolute cleanliness is paramount; the use of rags or lint-producing cloths is prohibited as particles can cause valve spool seizure. For Ross Hydrapower steering gears, remember that the worm shaft and rack piston are factory-matched components and must be replaced as a pair if damaged. When rebuilding Cessna gear pumps, ensure the moulded V-seals are seated correctly to prevent internal pressure loss. Adherence to the Piston Nut Torque Chart (Section 5) is critical during cylinder reassembly—specifically, 3/4" ID nuts must be torqued to 155 Lb. Ft. to maintain the integrity of the hydraulic seal.
