5. FAQ
Q1: Can this arm cylinder fit Komatsu PC60-5 or PC60-7 excavators?
A: No. Each Komatsu mini excavator model adopts exclusive part numbers and unique structural dimensions without interchangeability. Please confirm your full machine model before placing orders.
Q2: Does the standard package include the matching seal repair kit?
A: Seal repair kit is not included in standard delivery. You can purchase the dedicated supporting seal kit separately, and we will offer a competitive combined order quotation.
Q3: What packaging is adopted for long-distance overseas sea transportation?
A: Anti-rust oil filled into cylinder inner cavity, anti-rust grease evenly coated on piston rod surface. The whole cylinder wrapped with waterproof PE film and packed in reinforced export plywood cases to avoid collision, scratch and moisture damage during long ocean transit.
Q4: Are there tiered volume discounts when purchasing a full set of boom + arm + bucket cylinders?
A: Yes. Complete working device cylinder set orders enjoy graded volume discounts. Consolidated container shipment service is available to lower total logistics expenses.
Q5: What after-sales technical support is available if oil leakage occurs within the 12-month warranty period?
A: Please provide clear photos of leakage position plus excavator serial number. We will arrange free seal replacement and professional remote troubleshooting guidance promptly.
