Hydraulic Gear Pump JHP3160 (W-01-00147) for Changlin Loaders Expertise: A high-pressure hydraulic gear pump designed specifically for Changlin heavy machinery. The JHP series is known for its high volumetric efficiency and durability under extreme mechanical loads. This pump features a reinforced cast-iron body and precision-ground gears to ensure stable oil flow and pressure in the hydraulic system. Service Station Experience: We recommend this JHP3160 pump because it maintains consistent performance even when the hydraulic oil reaches high operating temperatures. In our experience, low-quality hydraulic pumps often lose pressure as the oil thins out, leading to "heavy" steering or slow bucket response. This genuine-spec pump ensures your loader remains responsive and productive. Mechanic's Tip: When replacing the hydraulic pump, it is mandatory to change the hydraulic filters and inspect the oil for metal shavings. If the previous pump failed due to contamination, the new one will fail rapidly without a system flush. Always prime the pump with clean hydraulic oil before the first start to prevent "dry" friction.
