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.

2. Technical Specifications
Pump Type: Variable Displacement Tandem Swash Plate Axial Piston Pump
Flow & Pressure Control: Features dual hydraulic regulators to automatically manage engine power distribution and main relief pressures (up to 34.3 MPa / 343 bar).
Drive Setup: Heavy-duty input spline shaft designed to couple directly with the excavator engine flywheel dampener.
Auxiliary Pilot Gear Pump: Includes integrated pilot gear pump to deliver pilot control circuit pressure.
3. Critical Installation Requirements
Hydraulic Case Priming (Mandatory)
Before starting the engine, manually fill the main pump casing with clean, fresh hydraulic fluid through the highest case drain port. Running an axial piston pump dry for even a few seconds will destroy the valve plates, swash plate, and piston slippers.
Complete Hydraulic System Flushing
If replacing a pump that suffered internal mechanical failure, you must drain and clean the hydraulic tank, flush the main lines and control valve, and replace all suction and return filters. Metallic debris remaining in the system will destroy the new pump.
Verify Pilot Line & Regulator Settings
Ensure pilot control pressure lines and regulator sense lines are connected correctly. Double-check that pilot pressure matches factory specs (typically 3.9–4.4 MPa) before attempting full-load operation.
Initial Startup Air Bleeding
After installing and pre-filling the pump, crack open the air bleed plugs on top of the pump housing while cranking the engine with fuel cut off until clear, bubble-free fluid emerges. Bleed trapped air to prevent cavitation.
4. Frequently Asked Questions (FAQ)
Q: Are part numbers 9150726, 9152668, 9151945, and 9155142 fully interchangeable?
A: Yes. These numbers represent standard Hitachi factory revisions, regulator tweaks, and production updates for the Dash-5 series excavators using the HPV102 platform.
Q: My EX200-5 stalls the engine when under heavy digging load. Is the main pump at fault?
A: Engine stalling under load usually indicates a sticking pump regulator or faulty proportional valve failing to destroke the pump when hydraulic demand exceeds engine output power.
Q: Is this pump supplied complete with the regulators and pilot pump attached?
A: Yes. The unit comes fully assembled with dual hydraulic regulators, input drive shaft, and the auxiliary pilot gear pump attached and pre-tested.
