10. Turn the fluid section counterclockwise to remove it from
the gear box housing.
11. Place the fluid section cylinder upright in a vise by
clamping on the wrench flats (Fig. 12, Item 1).
Do not over-tighten the vise. Damage to the
cylinder may occur.
12. Loosen and remove the inlet valve housing (2) from the
cylinder.
13. Remove bearing ring (3), O-ring (4), O-ring (5), inlet valve
seat (6), inlet valve ball (7) and upper ball guide (8).
14. Clean all the parts with the corresponding cleaning agent.
Check the inlet valve housing (2), inlet valve seat (6)
and inlet valve ball (7) for wear and replace the parts if
necessary. If the worn inlet valve seat (6) is unused on
one side, install it the other way around.

15. Using a wrench, remove the upper seal retainer (Fig. 13,
Item 1).
16. Slide the piston rod (2) out through the bottom of the
cylinder.
17. Inspect the piston rod (2) for wear and replace if
necessary.
20. Remove the cylinder from the vise.
21. Insert the connecting pin (3) through the hole at the top of
the piston rod (2) and clamp each end of the connecting
pin in the vise. This will hold the piston rod in position for
disassembly.
Do not clamp the piston rod directly in the vise.
Damage to the piston rod will occur.
19. Using a 3/8" hex wrench, loosen and remove the outlet
valve housing (4) from the piston rod (2).
20. Remove the upper seal (5), upper ball guide (6), outlet
valve ball (7), washer (8) and outlet valve seat (9).
21. Clean out any debris and examine the retainer (1) and
outlet valve seat (9). If the seat is damaged, reverse or
replace.

1. Remove inlet valve housing and piston in accordance with
steps 1-17 in Chapter 11.2, Page 14.
2. It is not necessary to remove the outlet valve.
3. Remove the upper support ring (Fig. 14, Item 6) and upper
packing assembly (1) from the top of the cylinder (2).
4. Remove the adapter (3) and lower packing assembly (4)
from the bottom of the cylinder.
Be careful not to scratch, score, or otherwise
damage the cylinder during removal of the
packings.
5. Clean the cylinder (2). Inspect the cylinder for damage
and replace if necessary.
6. Place the cylinder (2) upright in a vise by clamping on the
wrench flats (5).
7. Locate the new upper and lower packings and remove the
pre-form tools. Save the upper packing pre-form tool for
use as the piston insertion tool later in this procedure.
i
Do not remove the pre-form tools from the upper
