(1)Force works together as much as possible through three the bearing axis, which requires a springboard for symmetrical and smooth, spherical or parallel to the axis of force.

(2) the size of the force should be steady and uniform, not impact, which requires the use of hydraulic or with tools able to exert a steady pull or pressure, really had to use hammer, but also by the relatively soft copper sleeve, of scrap metal to be buffered by percussion force gently as possible. The best use of brass or copper hammer is for hammering.

(3) to avoid through the rolling force, which requires disassembly inner ring (shaft washer) through the inner force, when disassembly outer) through the outer force.

(4) drag force to continue to the appropriate degree of, for example, when installing the bearing in the bearing fits perfectly into the correct position to stop the force, to ensure the end of the ferrule (washer), arrived to rely on the shoulder end of the housing bore or shaft of the gear, neither packed too tight, can not be installed in place.
