Če se odločite za nakup opreme po nizki ceni, se prepričajte, da ste komunicirati z resničnim prodajalcem. Izvedite čim več informacij o lastniku opreme. Eden od načinov goljufanja se je predstavljati za resnično podjetje. V primeru suma o tem obvestite nas za dodatno kontrolo preko obrazca za povratne informacije.
Preden se odločite za nakup natančno preglejte več prodajnih ponudb, da boste razumeli povprečno ceno izbrane opreme. Če je cena ponudbe, ki vam je všeč, veliko nižja od podobnih ponudb, pomislite na to. Pomembna razlika v ceni lahko kaže na skrite napake ali pa na poskus prodajalca na goljufivo ravnanje.
Ne kupujte izdelkov, katerih cena je preveč drugačna od povprečne cene za podobno opremo.
Ne dajajte soglasja za dvomljive obljube in predplačane izdelke. V primeru dvoma se nikar ne bojte pojasniti podrobnosti, zahtevajte dodatne fotografije in dokumente za opremo, preverite pristnost dokumentov in postavite vprašanja.
Gre za najpogostejšo vrsto goljufije. Nepošteni prodajalci lahko zahtevajo določen znesek - predplačilo - torej "rezervacijo" vaše pravice do nakupa opreme. Tako goljufi lahko zberejo veliko količino denarja in izginejo, mi pa ne moremo več stopiti z njimi v stik.
- Prenos predplačila na kartico
- Ne opravite predplačila brez dokumentov, ki potrjujejo postopek prenosa denarja, če prodajalec v sporočilu izraža dvom.
- Prenos na račun "skrbnika" (agenta)
- Takšna zahteva bi morala biti zaskrbljujoča, verjetno komunicirate z goljufi.
- Prenos na račun podjetja s podobnim imenom
- Bodite previdni. Goljufi se lahko prikrijejo kot znane družbe, saj opravijo manjše spremembe imena. Ne prenesite sredstev, če je ime podjetja sumljivo.
- Zamenjava lastnih podatkov na računu resničnega podjetja
- Pred prenosom poskrbite, da so navedeni podatki pravilni in da se nanašajo točno na določeno podjetje.

Component: Main Hydraulic Pump Assembly
OEM Part Number: RC348-61110 (also handles engineering revisions RC348-61112 and RC348-61113)
Machine Compatibility:
Kubota KX61-3
Kubota KX71-3
Kubota KX71-3S
Condition: Original Brand New / OEM Specification
2. Technical Specifications
Pump Type: Triple Section Pump (Dual Variable Displacement Axial Piston Pump + Integrated Gear Pump)
System Output: Split-flow piston engineering that provides dedicated independent oil supply to the travel tracks, boom, and arm circuits for simultaneous multi-functioning without speed drops.
Operating Pressure: Factory-set to Kubota's exact system relief specifications (typically 21-23 MPa) to maintain breakout force.
Structure: Low-profile, compact cast iron and aluminum housing designed to bolt directly into the narrow Dash-3 engine bay.
3. Critical Installation Requirements
Case Priming (Mandatory)
You must manually fill the main pump housing with clean hydraulic oil through the highest case drain port BEFORE starting the engine for the first time. Operating a variable piston pump dry for even a few seconds will instantly score the cylinder block face and destroy the piston slippers.
Complete Hydraulic Decontamination
If the previous pump failed mechanically (sending steel or bronze debris into the system), you must drain and clean the hydraulic oil reservoir, flush the main control valve block, and clear out the hydraulic oil cooler lines. Trapped debris will quickly scratch the internal wear parts of the new pump.
Filtration and Fluid Change
Always replace the suction strainer, pilot filter, and high-pressure return filter with brand-new elements during installation. Fill the system using only fresh, clean ISO VG46 or Kubota-recommended anti-wear hydraulic oil.
Air Bleeding Protocol
After installation, run the engine at a low idle for 10 minutes. Slowly cycle each cylinder function (boom, arm, bucket, track travel) to its full limit without a workload to safely bleed any trapped air pockets back into the reservoir.
4. Frequently Asked Questions (FAQ)
Q: Are the pumps for the KX61-3, KX71-3, and KX71-3S completely identical?
A: Yes, these specific Dash-3 mini excavator models share the same engine configuration, chassis platform, and hydraulic layout, making part number RC348-61110 a direct interchangeable fit across all of them.
Q: My excavator slows down dramatically or stalls the engine when I use the boom and track at the same time. Is the pump broken?
A: This is a classic symptom of worn internal piston regulators or excessive internal oil bypass inside the pump. When the pump cannot properly adjust its swash-plate angle to match the workload, it overloads the engine. Replacing the pump assembly restores original speed and power.
Q: Does this pump include the regulators pre-installed?
A: Yes, our OEM Brand New pumps come as complete assemblies, featuring the pressure compensation regulators and internal control valves pre-calibrated and tested straight from the factory floor.
5. Shipping & Logistics
Packaging: Thoroughly drained of test fluids, coated in anti-corrosion protective oil, capped with heavy-duty port plugs, and packed inside a reinforced export shipping box.
Transit Time: Global express air freight via DHL/FedEx/UPS typically delivers within 3 to 7 business days directly to your shop or job site.
