常见问题
•Is it cheaper overall to import complete axles or rebuild locally with parts?
It depends on your labor cost and workshop skill. Complete assemblies cost more in freight and purchase price but eliminate rebuild labor, special tools and the risk of bad adjustment — decisive for fleets where vehicle downtime is expensive. Parts-level repair wins where labor is cheap and skilled. Many distributors stock both and let workshops choose.
•Are transfer cases and gearboxes tested before export shipment?
Factory-assembled units are bench-tested as part of production and ship with a passport recording serial number and acceptance. They arrive oil-drained or with preservation fluid — check the documentation and fill to specification before installation. Keep the passport: warranty claims on assemblies are processed against the serial number and proof of correct commissioning.
•Can I match a clutch kit if I only know the engine, not the part numbers?
Usually yes. Engine model plus vehicle modification identifies the clutch in the factory application tables — for example the diameter and spline count differ between engine families but are fixed within them. Send engine designation, year and gearbox type; the supplier returns the kit number. A photo of the old disc hub resolves ambiguous cases.
•Do driveshafts arrive balanced, and what about custom lengths?
Catalogue driveshafts are dynamically balanced at the factory and marked accordingly. Several plants also produce shafts to custom length for bus bodies, drilling rigs and special machinery — send the flange types, length between centers and operating speed. Balancing matters more at highway speeds, so do not economize on it for road vehicles.
•What warranty and claims process applies to complete drivetrain assemblies?
Typical export contracts warrant assemblies for a stated period or mileage against manufacturing defects, conditional on documented correct installation and lubrication. Claims run on the unit's serial number with photos and a description of failure circumstances; factories may request the failed unit or parts returned for analysis. Read the warranty clause before signing — terms vary between plants.
