Adjustment of bearings is accomplished by using varying
thicknesses of shim gaskets. Adjustment is correct when the
capscrews have been tightened and only the slightest drag is
noticeable when the crankshaft is rotated. If necessary, two or
more shim gaskets can be used on each end of the crankshaft to
obtain this adjustment.

4-3. R.O. PUMP SUCTION/DISCHARGE ASSEMBLY. (Figure 4-2)
a. General. The suction/discharge assembly of the R.O. pump is the section through which the water is
pumped. When the valve seats or packing in this assembly become worn, the pump will no longer function
property and the damaged parts must be replaced. This paragraph describes removal, disassembly, inspection,
cleaning, reassembly, and installation of the suction/discharge assembly.
