FAQ


Q: What type of gear oil is recommended for this compact final drive, and what is the optimal oil change interval?
A: We highly recommend using premium SAE 90 or 80W-90 heavy-duty gear oil. To maximize planetary gear life, perform the initial break-in oil change after 100 operating hours, and follow up with regular drain intervals every 500 hours.
 
Q: Does this travel assembly line up with the original standard or short-tail offset track shoes without frame trimming?
A: Yes, it is fully precision-machined to direct OEM dimensions. The hub mounting flange pattern matches both standard and short-tail crawler configurations flawlessly, requiring absolutely zero frame modifications or welding during replacement.
 
Q: How does your factory protect wholesale clients against shipping damages for heavy undercarriage assemblies?
A: Each assembly is thoroughly drained, treated with rust inhibitors, wrapped in vapor-barrier plastic bags, and secured tightly within robust export-grade wooden crates that withstand forklift handling and prolonged maritime freight cycles.
 
Q: Can this travel motor maintain full travel speed synchronization when operating on steep, frozen clay inclines?
A: It features high-capacity bimetal cylinder blocks that keep internal bypass slippage near zero. This ensures stable volumetric efficiency, allowing both tracks to draw matching power and maintain true straight tracking even on slick, icy grades.
 
Q: What quality options are available?

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