The following is the gear pump accessories when disassembling the attention should be paid to the problem: (1) towing force should be sustained to the extent possible, gear pump, for example, when installing the bearing in the bearing just installed in the right position to stop the force to ensure that the ferrule (Washer) end face against the seat hole or axis of the shoulder surface, neither can squeeze too tight, they can not fit not place. (2) the force of force through the oil-free bearings as possible axis, gear pump which requires the force point evenly symmetrical and stable, through the spherical surface or parallel to the axis of the force. (3) Avoid through the rolling body exertion, gear pump which requires the assembly and disassembly of the inner ring (shaft ring) through the inner ring force, when the outer ring assembly and disassembly force through the outer ring. (4) The size of the force should be smooth and uniform, should not be an impact, circular gear pump which requires the use of hydraulic or energy to exert a smooth pull or pressure tools, it is forced to use hammering, but also through the copper sleeve Soft and not falling debris metal to be buffered, tapping force as light as possible. Best to use copper rods or copper hammer for hammering.
