assembly not to mar or nick any smooth surface that comes in contact with seals. Before installing seals, always
apply a good lubricant, such as Lubriplate®, to the surfaces.
Clean parts in mineral spirits or other o'ring compatible solvent being sure to clean o'ring grooves. Inspect components for scoring,
excessive wear or damage.
