description

369-6595 axial variable piston pump acts as the core hydraulic power source of CAT 986H and 986K large wheel loaders. Driven by the C15 engine, it converts mechanical power into high-pressure hydraulic energy, supplying variable flow and pressure for boom lifting, bucket operation and steering actuators. The built-in load-sensing control automatically adjusts pump displacement according to real-time load demand. It only outputs required flow and pressure, reducing unnecessary power consumption and hydraulic heat buildup under heavy loading cycles. The core internal components are forged from high-strength alloy steel. Plungers, cylinder block, valve plate and sliding shoes go through precision grinding and nitriding hardening treatment, delivering outstanding wear resistance and fatigue resistance for repeated heavy material loading and stacking work. Thick cast iron pump housing adopts stress relief annealing to eliminate residual stress, resisting heavy impact and strong vibration in harsh mining environments, preventing pump deformation and cracking under peak load.

advantage

- 1:1 OEM full interchange, bolt-on fitment without modification
Manufactured strictly according to CAT 986H/986K loader OEM drawings. Mounting holes, oil ports and spline shaft fully match original 369-6595. Direct replacement shortens machine downtime and cuts service labor cost.
- Nitrided alloy steel friction pairs, stable volumetric efficiency under heavy cyclic load
Plunger, cylinder block and valve plate adopt deep nitrided alloy steel. It maintains stable volumetric efficiency under continuous heavy loading cycles, reduces internal oil leakage and extends service life.
- Load sensing control design, optimized power matching for large loader
High-precision swash plate automatically adjusts displacement following load demand. It saves engine power during light-load travel and delivers full flow for heavy digging, lowering fuel consumption and system heat generation.
- Reinforced thick cast iron housing for high-load mining application
Heavy cast iron housing with stress relief treatment. It withstands heavy impact and frequent pressure spikes in large quarry and mine sites, preventing pump housing deformation and cracking.
- Premium FKM sealing assembly for high-pressure and high-temperature working condition
High-quality FKM seals resist high temperature and hydraulic oil aging. Stable sealing reduces external oil seepage and internal leakage, keeping hydraulic circuit pressure consistent.

FAQ 

Q1: What machines does 369-6595 plunger pump fit?
A1: This main hydraulic pump is designed for CAT986H and CAT986K large wheel loaders equipped with C15 engine. It cannot be used for 980 series or other loader models. Confirm machine serial number and part number before purchase.

Q2: Is 369-6595 compatible for both steering and working hydraulic circuit?
A2: Yes. This main pump supplies pressurized hydraulic oil for both working circuit (boom & bucket) and steering circuit, it is the main power source of the whole hydraulic system.

Q3: What symptoms will occur when this main pump wears out?
A3: Typical failures: slow boom lifting under full load, weak bucket breakout force, steering becomes heavy, system pressure fluctuates, abnormal noise and vibration, hydraulic oil temperature rises rapidly during continuous loading.

Q4: Can this pump be installed directly on site?
A4: Yes. All installation dimensions, oil ports and spline shaft comply with OEM standard. Bolt-on installation without cutting or welding, simplifying field repair work.

Q5: What inspection items should be done before installing the new pump?
A5: Inspect relief valve, hydraulic cylinders and filter assembly. Flush oil tank and pipelines thoroughly to remove metal particles. Check oil cleanliness and replace hydraulic oil before assembly.

Q6: What hydraulic oil is recommended for this fan motor?
A6: Use ISO VG46 anti-wear hydraulic oil. Operating temperature range -25℃~110℃. Do not mix different oil brands, and avoid long time over-temperature operation.
