Genuine Hydraulic Gear Pump 6E3524 (6E-3524) For Cat 980C 980F Wheel Loader

This pure original high-precision heavy-duty hydraulic gear pump assembly has a core original part number of 6E3524 (6E-3524). As the core component of high-pressure fluid power transmission, this assembly is specially designed for Caterpillar's classic heavy-duty wheel loader, accurately matching the core star loader models of CAT 980C and 980F series, seamlessly serving the main hydraulic or steering assist circuit. The product is based on first principles optimization of high-strength gear meshing curve and wear-resistant side plate structure, with excellent volumetric efficiency, perfectly bearing extreme alternating impacts under shovel loading and heavy-duty lifting conditions, ensuring absolute certainty of fluid output. The physical dimensions of the product packaging are approximately 320mm × 240mm × 220mm, with an overall net weight of approximately 16kg. The original factory standard hole positions are precisely aligned.

"Extreme cleaning and torque tightening: Before lifting and docking, the installation flange and spline shaft must be kept absolutely clean and flat. The flange fastening bolts must be tightened using a torque wrench, strictly following the original factory torque standard for multi-stage, symmetrical cross tightening, to prevent local stress concentration from causing slight stress deformation of the aluminum side plate or shell.

Forced oil filling (core pit avoidance): After the pipeline is connected in place, clean hydraulic oil must be filled into the pump body from the inlet or top vent hole before the engine is ignited for the first time, and manually turned several times. It is strictly prohibited to start without oil dry grinding, otherwise the internal side plate and gear end face will experience instantaneous erosion within 3 seconds of ignition.

Low pressure transition and exhaust: After the first ignition, keep the engine idling for 10-15 minutes for full system automatic exhaust. Observe that there are no bubbles or abnormal noises in the fuel tank, and confirm that the thermodynamic state is stable before gradually applying normal working load."
