Q: What gear oil viscosity is recommended for breaking in a newly installed swing reduction box?
A: Use high-quality 80W-90 or 85W-140 industrial gear oil matching GL-5 standards. Change the initial oil fill after the first 50 operating hours to flush out break-in wear particles.

Q: How do you check for correct gear backlash between the swing pinion and the large slewing ring?
A: Mount a dial indicator on the excavator frame against a pinion tooth. Move the upper frame gently to measure free play, ensuring it stays within original factory limits.
Q: Are the planetary gear carriers made from forged steel or standard cast iron?
A: We use high-tensile forged nodular iron and alloy steel carriers. This construction provides much better impact resistance than standard cast alternatives.
Q: Can this reduction gearbox be delivered quickly to remote mining sites to prevent long project delays?
A: We maintain constant stock of our popular gearboxes and partner with fast international air freight carriers to ensure quick delivery to your site.
