5. FAQ
Q1: Can this arm cylinder fit Deere 790D or 892E LC excavator models?
A: No. Different Deere excavator models are equipped with exclusive part numbers and structural sizes, which are not interchangeable. Please confirm your equipment model and serial number 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 (PN: 4322741K), 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 with reinforced corners to ensure safe delivery.
Q4: Are there preferential policies for purchasing a full set of working device cylinders?
A: Yes. Orders for complete cylinder sets (boom + arm + bucket) enjoy tiered discounts (10-15% off). We also provide consolidated shipment service to help customers cut down logistics expenses by combining multiple items into a single container.
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 and purchase date. We will arrange free seal replacement and professional remote troubleshooting guidance within 48 hours. If necessary, we can also dispatch a technical engineer to your site (additional charges may apply for on-site service).
