NOTE: Since it is necessary to hold the piston rod stationary to remove the threaded adapter (10), use a
screwdriver in the slot (some models may have a hex wrench hole) in the back end of the piston to
keep the piston rod from turning. DO NOT scratch the piston shaft during disassembly.
8. Remove the piston rod assembly (3, Figure 6.4-1) by pushing on the threaded end (nosecap end) of the
piston rod until threads engage the sleeve (5, Figure 6.4-1). Thread the piston rod threads through the
sleeve (5, Figure 6.4-1) and remove the piston rod assembly from the unit.
9. Using the pin wrench supplied, remove the sleeve retainer (6, Figure 6.4-1).
10. Remove the brass sleeve (5, Figure 6.4-1).
11. Remove the handle assembly (11, Figure 6.4-1) by removing the four hex-head bolts.
Normal replacement of seals requires the use of Little Brute Seal Kit (LB-SK). Refer to Section 6.2.
12. Remove and replace the O-ring on the top face of the handle (4, Figure 6.2-1).
13. Remove the hydraulic adapter (6, Figure 6.1-1); replace the O-rings (3, Figure 6.2-1) and backup rings (2,
Figure 6.2-1).
14. Replace the hydraulic adapter (6, Figure 6.1-1) in the handle (11, Figure 6.4-1).
15. Remove and replace the O-ring (6, Figure 6.2-1) and backup ring (7, Figure 6.2-1) on the outside diameter
of the sleeve (5, Figure 6.4-1).
16. Remove and replace the O-ring (8, Figure 6.2-1) and backup ring (9, Figure 6.2-1) on the inside diameter of
the sleeve.
17. Replace the omni seal (10, Figure 6.2-1) on the air seal adapter (1, Figure 6.1-1).
18. Remove and replace the O-ring (6, Figure 6.2-1) and backup ring (7, Figure 6.2-1) on the piston rod
assembly.
