If you decide to buy equipment at a low price, make sure that you communicate with the real seller. Find out as much information about the owner of the equipment as possible. One way of cheating is to represent yourself as a real company. In case of suspicion, inform us about this for additional control, through the feedback form.
Before you decide to make a purchase, carefully review several sales offers to understand the average cost of your chosen equipment. If the price of the offer you like is much lower than similar offers, think about it. A significant price difference may indicate hidden defects or an attempt by the seller to commit fraudulent acts.
Do not buy products which price is too different from the average price for similar equipment.
Do not give consent to dubious pledges and prepaid goods. In case of doubt, do not be afraid to clarify details, ask for additional photographs and documents for equipment, check the authenticity of documents, ask questions.
The most common type of fraud. Unfair sellers may request a certain amount of advance payment to “book” your right to purchase equipment. Thus, fraudsters can collect a large amount and disappear, no longer get in touch.
- Transfer of prepayment to the card
- Do not make an advance payment without paperwork confirming the process of transferring money, if during the communication the seller is in doubt.
- Transfer to the “Trustee” account
- Such a request should be alarming, most likely you are communicating with a fraudster.
- Transfer to a company account with a similar name
- Be careful, fraudsters may disguise themselves as well-known companies, making minor changes to the name. Do not transfer funds if the company name is in doubt.
- Substitution of own details in the invoice of a real company
- Before making a transfer, make sure that the specified details are correct, and whether they relate to the specified company.

KYB PSVL-54CG-13 Hydraulic Main Pump for CAT 304C CR 305D CR | Part No. 266-6942 2666942
1. Product Overview
The KYB PSVL-54CG-13 is a high-performance, variable displacement axial piston pump engineered for the heavy-duty cycles of the 4 to 5-ton mini excavator class. As the primary hydraulic power unit for the CAT 304C and 305D series, it provides the precise flow and high-pressure output required for smooth, synchronized movements of the boom, bucket, and travel motors. Its robust design is specifically optimized for "Compact Radius" (CR) machines, ensuring peak power delivery within a confined engine compartment.

4. Critical Installation & Maintenance Protocol
Case Priming (Mandatory): You must fill the pump housing with clean, fresh hydraulic oil through the highest drain port before starting the engine. Running the pump "dry" will cause immediate and irreversible internal damage to the pistons and bearings.
System Decontamination: If the previous pump suffered a mechanical failure (metal-to-metal contact), you must flush the entire hydraulic tank, lines, and oil cooler. Residual metallic debris is the primary cause of premature failure in replacement pumps.
Filter Mandate: Always install a new high-efficiency hydraulic return filter and suction strainer during the pump replacement to maintain oil cleanliness and protect the precision internal components.
5. Ordering & Professional Support
Fitment Verification: To ensure 100% accuracy, please provide your machine Serial Number (e.g., Prefix FPK or HWZ) or a photo of your existing pump nameplate.
