5. FAQ
Q1: Is this boom cylinder compatible with EC160C or other updated variants?
A: No. Different upgraded models are equipped with exclusive part numbers and structural dimensions, which cannot be used interchangeably. Please verify your excavator model before placing orders.
Q2: Does the standard delivery package include the seal repair kit?
A: The seal repair kit is not included in standard products. You can purchase the dedicated matching kit separately, and we will offer a competitive price for combined orders.
Q3: What kind of packaging is used for overseas sea transportation?
A: We inject anti-rust oil into the cylinder interior and coat anti-rust grease on the piston rod surface. The whole product is wrapped with waterproof PE film and packed in solid export plywood cases.
Q4: Can we get preferential rates when purchasing a full set of working device cylinders?
A: Yes. Purchasing complete cylinder sets will enjoy tiered discounts. We also provide combined shipment service to help customers reduce logistics costs.
Q5: What support can we receive if oil leakage occurs during the warranty period?
A: Please take clear photos of the leaking area and provide the excavator serial number. We will arrange free replacement of sealing parts and professional remote technical guidance in a timely manner.
