5. FAQ
Q1: Can this arm cylinder fit Hitachi ZX400 or ZX470 excavator models?
A: No. Different Hitachi excavator models are equipped with exclusive part numbers and structural sizes, which are not interchangeable. Please confirm your equipment model before placing orders.
Q2: Does the standard package include the dedied seal repair kit?
A: The seal repair kit is not included in standard products. You can purchase the matching repair kit separately, and we will offer a favorable price for combined orders.
Q3: What packaging is used for long-distance overseas sea transportation?
A: Anti-rust oil is injected into the cylinder interior, and anti-rust grease is applied on the piston rod surface. The whole product is wrapped with waterproof PE film and packed in solid export plywood cases.
Q4: Are there preferential policies for purchasing a full set of working device cylinders?
A: Yes. Orders for complete cylinder sets enjoy tiered discounts. We also provide consolidated shipment service to help customers cut down logistics expenses.
Q5: What after-sales support will be provided if oil leakage occurs within the warranty period?
A: Please take clear photos of the leakage position and provide the excavator serial number. We will arrange free seal replacement and professional remote troubleshooting guidance in a timely manner.
