1. Isolate the oil on the left side of the exhaust valve of the planetary reducer from other oils, and the oil level is only slightly higher than the horizontal partition wall.
2. Move the fuel tank and exhaust valve to the side to lower the oil level and reduce the oil volume.
3. The plane of the reducer base should be flat, and the valve body should be more flexible.
4. Bearings and seals must be reliable and replaced in time.
5. Add a pipe to the oil hole so that the oil level is only slightly higher than the oil inlet.
6. The check valve system organization of the reducer is installed, and the oil inlet hole can be actively closed when the reducer is stopped.
