5. Pre-clean the piston and cylinder using solvent soaked wipers.
6. Prepare additional wipers as necessary for drying the piston and cylinder once they
have been washed with soap and water.
7. Scrub the bore of the cylinder using a soft bottle brush, Cashmere Bouquet soap and
warm tap water.
8. Rinse thoroughly and dry immediately using the pre-twisted wipers.
9. Set the cylinder aside and cover with a clean dry wiper.
10. Using soft paper wiper, Cashmere Bouquet soap and warm tap water, scrub the
outside of the piston.
11. Rinse thoroughly and dry immediately.
12. Set the piston aside and cover with a clean dry wiper. Allow the piston and cylinder
to set for about 15 minutes before reassembly.
13. Clean the thrust bearing, cylinder container and upper retaining ring using solvent
soaked wipers and set aside.
14. Inspect the o-rings for any sign of damage, replace as necessary.
15. Apply a slight amount of lubricant to the o-rings and wipe off any excess.
16. Place the cylinder upright (narrow neck downward) on the work area.
17. Carefully inset the piston into the top of the cylinder and allow it to sink freely into
the cylinder. Do not force the piston into the cylinder or it may be damaged.
18. If lint becomes a problem a clean dry gas source can be used to blow the lint off of
the parts prior to assembly.
19. Install the thrust bearing around the bottom o the piston with the flange of the outer
race facing the bottom of the cylinder.
20. Install the retaining clip onto the bottom of the piston using the installation tool. The
end of the piston must be supported during the retaining clip installation so as not to
risk breading the piston.
21. Install the assembly into the instrument base and test according to Chapter 6,
Functional Testing of Piston/Cylinder Assemblies.
22. Prior to using the pin vise, be sure it is clean and in good working order. Disassemble
the pin vise and clean the components with solvent soaked wipes.
