Note the absence of oil-bearing disassembly

When the oil-bearing disassembly pay attention to the problem:
(1) to continue to the extent of the drag force due to the biasing stop just installed in the correct position when the sliding bearings to ensure retaining shoulder end rings (gaskets) against the end surface of the housing bore or shaft, neither packed too tight, it can not be installed in place.
(2) as far as possible by the urging force of the oil-bearing axis, the gear pump which requires a springboard for symmetrical and smooth, parallel to the axis through the spherical or biased.
(3) avoid the rolling elements by urging the inner ring by urging the gear pump which requires disassembly inner ring (shaft washer), the urging by the outer ring when the outer ring assembly and disassembly.
When stationary (4) urging the size should be uniform, not an impact, arc gear pump which requires the use of hydraulic or able to exert steady pressure or tension tool, it had to use a hammer, but also through the copper sleeve and other softer and not of scrap metal to be buffered, percussion force gently as possible. Best to use copper or copper hammer hammering.
