DETAILED DESCRIPTION
[0025] The utility model will be further described in combination with the drawings: Example 1
[0026] like Figure 1 As shown, a disassembly tool 100 for a gear oil pump bearing housing includes a left rod 1 and a right rod 2, with a gap between them. Their upper ends are connected, and their lower ends respectively have a left hanging leg 101 extending to the left and a right hanging leg 201 extending to the right. The lower sections of the left rod 1 and right rod 2 can move towards each other and away from each other within a set range. (See application...) Figure 6 The lower sections of the left rod 1 and right rod 2 are brought together and inserted into the holes of the left bearing seat 5 and right bearing seat 6, respectively. Then, the lower sections of the left rod 1 and right rod 2 are separated, so that the left hook 101 of the left rod 1 and the right hook 201 of the right rod 2 hook onto the bottom end face of the left bearing seat 5 and the right end face of the right bearing seat 6, respectively.
