description

104-1752 axial variable piston pump serves as main hydraulic power unit for CAT D9R bulldozer, driven by engine. It converts mechanical power into adjustable high-pressure hydraulic energy for blade, ripper and steering hydraulic systems. Built-in load sensing control valve dynamically changes pump displacement. During heavy dozing and ripping, pump increases flow to maintain blade movement 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 strong vibration and particle contamination in mine and earthmoving 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

- High peak pressure resistance for rock ripping and heavy cutting tasks
Strong pressure withstand capability supports high load ripping operation, maintaining stable pushing force when dealing with hard compacted ground and rock layers.
- Multi-circuit flow sharing for simultaneous blade adjustment and steering
Precise flow distribution enables blade lifting/tilting, ripper movement and steering to work at the same time without obvious power competition, improving earthmoving efficiency.
- Reinforced internal friction pair for continuous heavy rock breaking
Upgraded friction pair structure improves wear resistance, coping with long-hour heavy-duty ripping and repeated impact load in mining stripping projects.
- Optimized pressure stability to avoid blade sinking during static hold
Excellent pressure retention prevents blade sagging when holding position on slope, maintaining stable working posture for long-duration grading work.
- Full dozing & ripping cycle bench test simulating mine stripping condition
Each pump undergoes cyclic test simulating pushing, lifting and ripping operations, verifying reliable performance under long-time heavy-load mine stripping.

FAQ 

Q1: Which machine does 104-1752 (0R-7669) plunger pump fit?
A1: This hydraulic plunger pump is designed for CAT D9R bulldozer, supplying hydraulic power for blade and ripper system. Confirm machine serial number before purchase.

Q2: What hydraulic functions does this pump support?
A2: It provides high-pressure hydraulic oil for blade lift, blade tilt, ripper operation and vehicle steering, completing earthmoving, rock ripping and land grading work.

Q3: What are typical failure symptoms of worn pump?
A3: Typical symptoms: insufficient pushing force on hard ground, slow blade lifting and tilting, blade sinks during holding, obvious temperature rise during continuous ripping, pump abnormal noise and shaft seal oil leakage.

Q4: What inspections should be done before installing new pump?
A4: Inspect blade cylinders, ripper 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 bulldozer still lacks pushing 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.
