5. FAQ
Q1: Can this arm cylinder be used on Hyundai R920 or R940 excavator models?
A: No. Different Hyundai excavator models utilize exclusive part numbers and structural dimensions, so they are not interchangeable. Please verify your equipment model before placing orders.
Q2: Does the standard package include the matching seal repair kit?
A: The seal repair kit is not included in standard products. You can order the dedicated repair kit separately, and we will offer a competitive rate 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 entire unit is wrapped with waterproof PE film and packed in heavy-duty export plywood cases to ensure safe transit.
Q4: Are there preferential prices for purchasing a full set of working device cylinders?
A: Yes. Customers who purchase complete cylinder sets (boom, arm, and bucket) will enjoy tiered discounts. We also provide consolidated shipment service to help reduce logistics costs.
Q5: What support is available if oil leakage occurs within the warranty period?
A: Please take clear photos of the leaking area and provide the excavator serial number. We will arrange free seal replacement and professional remote technical guidance promptly to resolve the issue.
