Cone Crusher General Maintenance Information

When performing any maintenance work on the cone crusher, the following general precautions should be observed:

1. When removing parts with machined or bearing surfaces that may rust, they should be well oiled or covered with a rust preventive, if they are to be kept out of the cone crusher for any length of time.
2. Use additional caution when handling any parts which have bearing surfaces or a machined surface that has close tolerances.
3. When disassembling any parts with bearing or machined surfaces, protect these surfaces from coming in contact with the ground by using wooden blocking.
4. Bronze liners or bushings should be handled with extreme care. Excessive ramming or pounding on this soft material may cause warping or springing of such parts.
5. Clean thoroughly and oil all machined parts before installing them in the cone crusher. Do not replace a bearing surface without coating it with oil.
6. When assembling two mating parts that require either a press or sliding fit, coat the contacting surfaces with a light coating of oil. This will act as a lubricant and prevent rusting in place.
7. Head and eccentric bushings are to be stored vertically, stored in any other position could cause the bushings to become out-of-round or elliptical. Great difficulty could consequently be encountered when installing them in the cone crusher. In some instances installation would be impossible.
8. All bowl, adjustment ring, clamping ring, head and locking nut thread surfaces are to be rubbed with a cloth impregnated with powdered molybdenum disulfide and then coated with grease or oil. Again, should this powder be unobtainable, grease applied liberally is a good substitute.
