description

AL213995 / AL161043 axial variable piston pump serves as main hydraulic power unit for John Deere loader, driven by engine. It converts mechanical power into adjustable high-pressure hydraulic energy for boom, bucket and steering hydraulic systems. Built-in load sensing control valve dynamically changes pump displacement. During bucket digging and heavy loading, pump increases flow to maintain boom speed; under light load or idle travel, it reduces displacement to save fuel and reduce heat accumulation. Internal plungers, cylinder block, valve plate and slipper assemblies are manufactured from high-strength alloy steel with precision grinding and surface hardening treatment. Cast iron housing adopts stress relief annealing to eliminate casting residual stress, resisting vibration and particle contamination in farm and aggregate sites. High-performance FKM fluorine rubber sealing assembly delivers reliable high temperature resistance and anti-aging property, reducing internal volumetric leakage and external oil seepage.

advantage

- Load sensing response optimized for mixed farm and aggregate loading tasks
The load sensing curve is tuned for versatile working scenarios. It quickly builds pressure when bucket cuts into soil, grain or gravel piles and automatically reduces flow during boom holding to cut power waste.
- Balanced compound action performance for simultaneous boom lift and bucket curl
Stable flow sharing allows boom lifting and bucket curling to run concurrently without obvious power drop, improving efficiency for multi-purpose loading on mixed job sites.
- Durable internal friction pair for variable mixed-material shovel impact
Enhanced friction pair structure can handle alternating loads from soil, grain and gravel, resisting wear under diversified cyclic loading conditions.
- Reliable static pressure retention for material stacking on uneven ground
Good pressure holding capability prevents boom sinking during static positioning on uneven farm ground, maintaining stable posture for stacking and material handling.
- Optimized internal flow channel reduces pulsation and system heat generation
Refined hydraulic passage design lowers pressure fluctuation during variable displacement adjustment, reducing system heat and extending service life of related hydraulic components.

FAQ 

Q1: Which machine does AL213995 / AL161043 plunger pump fit?
A1: This hydraulic plunger pump is designed for John Deere loaders. AL213995 and AL161043 are interchangeable. Confirm machine serial number before purchase.

Q2: What hydraulic functions does this pump support?
A2: It provides high-pressure hydraulic oil for boom lifting/lowering, bucket tilt, bucket curl and vehicle steering, completing earthmoving, grain handling and aggregate loading work.

Q3: What are typical failure symptoms of worn pump?
A3: Typical symptoms: insufficient digging force for compacted soil or gravel, slow boom lifting under heavy load, boom drifts during static holding, temperature rise during continuous loading, pump abnormal noise and shaft seal oil leakage.

Q4: What inspections should be done before installing new pump?
A4: Inspect boom cylinders, bucket cylinder, multi-way valve and filter elements. Fully flush hydraulic tank and pipelines to remove metal debris. Replace degraded hydraulic oil before assembly.

Q5: Why loader still lacks digging force after pump replacement?
A5: The fault may not come from pump. Check relief valve calibration, stuck valve spool, clogged filter, damaged cylinder seals or trapped air inside hydraulic circuit. Air bleeding must be completed after installation.
