A pivot assembly for securing a pair of mounting lugs and stabilizing a machine member has an axis member having a first end member and a second end member. An opening is formed in both the first and second end members. A pair of expansion sleeves is provided wherein one of the pair of expansion sleeves is positioned over each of the first end and second end members. A pair of locking devices is provided wherein one locking device is inserted into the opening formed in each of the first and second end members of the axis member. The locking devices engage the pair of expansion sleeves causing the expansion sleeves to expand to secure the axis member in a pair of mounting lugs. A chamber member is formed around a central area of the axis member. At least one lubricant chamber member is formed between the central area of the axis member and the chamber member. A pair of friction seal members is provided wherein one friction seal member is attached on each end of the axis member and to the chamber member to form an annular sealing around the axis member and the chamber member to prevent a lubricant in the lubricant chamber member from leaking.
