A bowl liner for use in a cone crusher that is comprised of a pair of bowl liner sections joined to each other to define the bowl liner. Each of the bowl liner sections includes first and second ends that engage opposite first and second vertical ends of the second bowl liner section. The first and second ends include key features that limit the axial movement of the first and second bowl liner sections relative to each other. Each of the first and second bowl liner sections further include a radial key and mating key slot to limit the radial movement between the bowl liner sections. The vertical joint between the bowl liner sections includes an inner relief that allows for manganese growth during use of the bowl liner.

A counterweight for use in a cone crusher that includes an inner oil chamber and an outer oil chamber to collect lubricating oil during operation of the cone crusher. The counterweight includes a vertical separating wall that receives a splash shield. The vertical separating wall and splash shield define an inner oil chamber while an outer oil chamber is defined by the splash shield, the vertical separating wall and an inner wall of the counterweight. Both the inner and outer oil chambers include drain holes that allow lubricating oil to pass through a generally horizontal floor of the counterweight. The combination of the inner and outer oil chambers allows oil to quickly exit the counterweight into the main oil sump and reduces the amount of oil that gets exposed to the upper seal assembly which reduces the passage of oil past seal assemblies formed in the cone crusher.

A two-piece locking nut assembly for securing a mantle to a head assembly of a cone crusher. The two-piece locking nut assembly includes an inner nut and an outer nut. The inner nut includes a set of axial bores that each receive a jackscrew. Once the locking nut assembly is in position on the head assembly, the series of jackscrews are tightened to exert a force on the mantle that is counteracted by forces through the inner nut and into the head to create a locking force between the locking nut assembly and the head assembly. The outer nut is turned along the inner nut to hold the locking nut assembly in place. Once the outer nut is moved into position, the jackscrews are removed such that the outer nut continues to apply the locking force between the mantle and the head through the locking nut assembly.
