FAQ


Q: How to tell if the second-stage carrier is failing versus the first-stage?
A: Second-stage failure shows intermittent track slippage under heavy load but normal movement unloaded. First-stage failure typically causes complete loss of motion. Drain metal flakes (larger chunks) point to second-stage.
 
Q: What is the most critical measurement before installing XKAQ-00974?
A: Measure planet gear axial float against carrier pocket bottom. Correct range is 0.15–0.30mm. Too little causes overheating; too much allows gear tilt and edge loading.
 
Q: Will XKAQ-00974 fit if my Hyundai R330-9 has an aftermarket final drive housing?
A: Not always – some aftermarket housings use non-standard carrier dimensions. Please provide your current carrier outer diameter and pin hole center circle measurement. We verify before shipping.
 
Q: Does this carrier perform reliably in freezing Arctic or hot desert mines?
A: Yes – 42CrMo maintains impact toughness down to -40°C. At high temperatures (+100°C), the through-hardened core prevents softening. Proven in Canadian oil sands and Australian iron ore sites.
 
Q: What quality options are available?

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