About Xinfeng Machinery (XF) parts:
Maintenance method
1. The lubriing oil maintenance cycle of the rotary motor is 1000 hours. In daily operation, we need to observe the amount of rotary lubriing oil from the dipstick. In some cases, abnormal loss of lubriing oil will be found, so we need to open the large ring gear window. Check whether lubriing oil leaks into the large ring gear cavity through the sealing ring.
2. The general rotation gear inspection and lubriing oil replacement cycle is every 2000 hours or one year. The butter filling amount for a 20-ton machine is about 36 liters (two barrels). Periodically open the boom base and the square cover on the front of the frame. , to check the ring gear and lubriion conditions. For maintenance or if water is found, go to the X overhead cavity at the bottom of the excavator and open the cover to release the water.
3.There is a common misunderstanding among customers about the maintenance of slewing bearings. They believe that the lubriing oil of the slewing bearing is the same as the lubriion cycle of the big and small arms, and they need to be lubried every day. In fact, such actions have the opposite effect. If the lubriion cycle is too short, there will be too much lubriing oil in the bearing, which will burst the dust ring and leak out.
