Usually Lude bevel gearboxes are filled with gear oil for normal operation before leaving the factory and are ready for use.The standard gear oil is HD320~680.
Notes:Delivered gearboxes by air/express without gear oil.To prevent the gearbox leak,we do inject gear oil to inspect them,after that, exhaust the gear oil before shipment.
Normal working conditions, after 300 work hours, first time to inject grease. After that,each time per 1500 work hours.
