The invention discloses a tool and method for replacing a main transmission shaft ring type grease pump. The tool comprises a supporting plate, a suspension arm, a gear, a first C-shaped clamping jaw and a second C-shaped clamping jaw. One side of the supporting plate is rotationally connected with two handles; any handle is connected with a gear through a rotating shaft penetrating through the supporting plate. Openings of the first C-shaped clamping jaw and the second C-shaped clamping jaw are opposite, a row of groove teeth are arranged on the outer side of a wing plate on one side of the first C-shaped clamping jaw and the second C-shaped clamping jaw, and the groove teeth are meshed with the gear. The gear rotates to drive the first C-shaped clamping jaw or the second C-shaped clamping jaw to move up and down; web plates of the first C-shaped clamping jaw and the second C-shaped clamping jaw are provided with telescopic adjusting mechanisms, and bolt holes matched with the outer sleeve or the inner sleeve splicing bolts are formed in the inner buckling pieces of the wing plates on the two sides. The semicircular flange of the outer sleeve or the inner sleeve of the ring type grease pump is integrally hoisted through the tool, and the installation efficiency and precision are improved.
