to adjust to the point of eliminating the longitudinal play of the sample chamber.
26. Tighten the sleeve in 24 1/4-turn increments (6 turns total) to preload the seals.
27. Lightly lubricate the inside bore of the cylinder.
28. Align the fittings on the cylinder with the sample chamber tubes, or with air lines if servicing.
