Cleaning and Inspecting
Clean Parts
1. Determine which parts are going to be reused and discard the rest.
Note All parts can be cleaned in most solvents, but it is inadvisable to let the parts
soak in acetone for any length of time.
2. Using a wire brush, thoroughly clan all threads and remove residue from all components.
Note When cleaning the foot valve and piston body on stainless-steel fluid sections
use caution not to damage the Kalrez O-ring on the ball seat.
3. If you have the stainless-steel version of the fluid section, inspect the Kalrez O-ring in the
foot valve and piston body closely without removing, and if they are in good condition, wipe
off with solvent and leave in place.
Inspect Parts
Note After all the parts have been thoroughly cleaned it is important to inspect them
for damage. If a faulty part is not replaced it could give poor performance and
damage the entire assembly.
4. Ensure that the bearing in the ball joint rod end swivels and rotates freely.
5. Make sure the threads on the packing nut are clean and not marred.
6. Check for wear on the inside diameter of the male and female compression
rings.
7. Make sure the threads on the outlet body are clean and not marred.
8. Clear any buildup from the area where the piston rod packing assembly is
placed.
9. Ensure the piston ball spring is not bent.
10. Make sure the chrome ball that goes in the piston body is not dented, pitted, or scratched.
11. Make sure the piston rod threads are clean and not marred.
12. Check the piston rod spring guide to make sure it is straight.
13. Ensure there is no buildup inside the piston rod chamber.
14. Check the polished part of the piston rod for wear.
15. Make sure the threads on the piston body are clean and not marred.
16. Check the piston body ball seat for wear or damage.
Note The ball seat on the stainless steel version is behind the Kalrez O-ring, which
must also be inspected and replaced if damaged.
