PC240‑6 PC240‑6K PC240NLC‑6K Hydraulic Pump for Komatsu Excavator spare parts 708‑2L‑00422 Aftermarket

Product Brief

This aftermarket variable axial piston main pump, part number 708‑2L‑00422, serves as the core hydraulic power heart for Komatsu PC240‑6, PC240‑6K, PC240NLC‑6K excavators. It converts engine mechanical output into adjustable high‑pressure hydraulic flow to fulfill heavy‑duty tasks including digging, material loading, site grading and multi‑joint compound actions. Widely used in earth‑moving, quarry operation and land re‑conditioning projects, this aftermarket pump is highly sought‑after by overseas repair garages, equipment rental operators and cross‑border spare‑part dealers for field‑direct replacement and periodic hydraulic system overhaul of Komatsu 240‑6 series machine fleets.

Under continuous heavy load cycles, contaminated hydraulic oil and frequent pressure surges on tough construction sites, the original pump will gradually develop cylinder barrel scratches, piston shoe wear, valve plate erosion and increased internal leakage. Typical fault manifestations include weakened digging output, sluggish boom‑arm response, insufficient travel power, persistent high hydraulic oil temperature, plus obvious pump vibration and knocking sound under digging load. Once the main pump suffers total failure, the whole excavator stops operation, bringing unexpected project downtime and extra maintenance costs for end‑users.

Our aftermarket replacement pump strictly references original sample specifications for mounting hole layout, input shaft spline profile, oil port placement and regulator pressure preset values. Field technicians can achieve direct fitment without cutting, drilling or extra adapter modification, effectively minimizing machine downtime. Compared with high‑cost genuine original pumps with long procurement lead‑times, this hydraulic pump delivers reliable practical performance and meets recurring bulk‑order demands for global Komatsu excavator spare‑part distributors.

Product Highlights

1. Full dimensional interchangeability for fast on‑site overhaul
All critical mounting sizes, spline tooth parameters and oil port positions match the original assembly. Service crews can complete pump dismounting and installation without secondary machining work, raising overhaul efficiency for repair shops and used‑equipment refurbishment projects.

2. Optimized friction‑pair craftsmanship for harsh working scenarios
Many low‑cost alternative pumps suffer rapid performance decay when paired with aged hydraulic systems carrying fine impurity particles. Our key internal friction components adopt upgraded heat‑treatment together with multi‑step precision lapping process, improving anti‑wear and anti‑pressure‑shock performance, and extending service life for PC240‑6 series machines working on earth‑moving and quarry sites.

3. Strict bench validation before product dispatch
Each finished hydraulic pump undergoes pressure endurance testing, flow parameter calibration and sealing leakage inspection on dedicated hydraulic test benches prior to packing. Potential defective units are screened inside the factory, lowering re‑work risks for service teams and preventing unplanned construction‑site shutdown caused by pump breakdown.

4. Cost‑saving aftermarket choice for medium‑large excavator fleet maintenance
Genuine main pumps for Komatsu PC240‑6 series carry high purchase cost and unstable stock availability. Our factory‑direct aftermarket replacement pump balances dependable operating stability and competitive pricing, helping equipment owners and service merchants control overall maintenance expenditure for Komatsu excavator fleets.

5. Diverse logistics options for bulk‑order traders
In‑stock items support prompt shipment upon payment confirmation. Air freight is available for urgent emergency breakdown orders. Sea consolidation and full‑container transport solutions help overseas bulk buyers cut comprehensive logistics expenses.

Factory Production Strength

Our manufacturing base specializes in R&D and volume manufacturing of aftermarket hydraulic replacement components for Japanese‑brand excavators, covering main hydraulic pumps, travel gearboxes and swing motors. We maintain complete production workflows: alloy‑steel forging, precision grinding, professional heat‑treatment and finished‑product hydraulic bench verification. Simulated heavy‑duty cyclic load tests are performed to validate component durability under real‑world earth‑moving and infrastructure‑building conditions. Our spare parts are exported to multiple overseas regions and maintain long‑run stable partnerships with global construction‑machinery spare‑part wholesalers.

Frequently Asked Customer Questions

Q1: Can this 708‑2L‑00422 hydraulic pump fit other Komatsu excavator models?
A1: Cross‑model installation is not recommended. Different pump assemblies vary in shaft spline, regulator setup and pressure calibration parameters. Please double‑check your machine model and original part number before submitting orders.

Q2: What hydraulic malfunctions can this main pump remedy?
A2: It resolves faults induced by internal‑component abrasion: insufficient digging force, slow compound movements, excessive hydraulic oil temperature, internal leakage and abnormal pump vibration or knocking noise.

Q3: Is volume‑based tiered discount available for large‑quantity orders?
A3: Yes, preferential pricing applies according to order volume. Full‑container sea freight arrangement can be supported to cut total logistics cost.

Q4: What export‑grade packaging is used for long‑distance overseas shipment?
A4: Anti‑rust grease is evenly applied to all metal functional surfaces. The hydraulic pump is wrapped with waterproof shock‑absorbing PE film, then secured inside reinforced export plywood case, protecting components against collision deformation and rust accumulation during long‑haul ocean transit.
