FAQ


Q: How to know if the carrier assembly itself is damaged versus the bearings?
A: Uneven rotation with metal flakes on drain plug but no bearing rumble suggests carrier pocket wear. If pin holes become oval, the carrier must be replaced; bearings alone won't fix it.
 
Q:What pre-assembly check is critical before installing XKAQ-00400?
A: Always measure planet gear axial play inside each pocket. Acceptable range is 0.10–0.25mm. Tighter clearance causes binding; looser clearance leads to rapid pocket hammering.
 
Q: Will XKAQ-00400 fit my machine if the serial number is different from R330-9?
A: Not all Hyundai 30-ton models share the same carrier. Please confirm your swing drive housing casting number and original part number. We cross-match to avoid wrong shipments.
 
Q: Does this carrier assembly perform reliably in sandy or high-dust mines?
A: Yes – the phosphate coating prevents micro-welding from sand ingress. The closed pocket design also reduces abrasive particle entrapment, proven in Middle East desert operations.
 
Q: What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
