general
For component identication, see Figures 2, 7, 14, & 15.
1. Secure the head/handle (1) upside-down in a soft-
jaw vise. (Figure 2) Place the inverted cylinder
assembly (35) on the base of the handle. (The timing
pin maintains orientation.)
2. Assemble the gland assembly (25) with new seals.
(Note the orientation of the Polyseal (18) in Figure
7.) Apply Anti-Seize Compound (P/N 508183) to
the threads of the gland assembly. Screw the gland
assembly into the head/handle and torque it to 50 ft.-
lbs. using a 1-3/8” socket wrench.
3. Push bumper (34) rmly over gland.
NOTE: The side of the bumper with two slots must
face the bottom of the tool.
4. Install the Quad-ring (47) onto the air piston (37).
5. Lubricate the piston rod. Press the assembled air
piston/rod into the cylinder just enough to allow
installation of the cylinder head (45).
6. Assemble O-Ring (46) onto the cylinder head (45)
and then push the cylinder head squarely into the
cylinder, taking care not to damage O-ring (46).
Install the retaining ring (38); align the screw holes
with the mufer end cap.
7. Position the mufer (42) in center of cylinder head.
Position the gasket (39) on cylinder. (Figure 2) Note
the direction of the lip in Figure 7.
8. Carefully position the bottom plate (41) on cylinder.
Make sure that the mufer is properly positioned in
the recess of the bottom plate (41). (Figures 2 & 14)
9. Secure the bottom plate with the three button head
screws (40) using a 1/8” hex key. (Figure 2)
10. Assemble O-rings (50) on throttle valve (52). (Figure
14 Section CC)
11. Place the tool upright on a level surface. Drop the
spring (49) into the throttle valve bore in the cylinder
(35), and push the throttle valve into the cylinder.
12. Place the ball end of the throttle cable (2) into the
end of the throttle arm (53), then slide the throttle
arm into the slot on the cylinder. (Figure 14)
13. Snap the lever guard (73) in place, and install the
pivot screw (48) in the cylinder to retain the throttle
arm (53).
14. Models 2025 & 2025L: Push the pintail deector (24)
onto the end cap (21).
Models 2025B & 2025LB: Position the adapter (64)
and pintail bottle (24) on the end cap. Reach in the
window of the pintail bottle and install the retaining
ring (62) and washer (63). (Figures 14 & 15)
Models 2025V & 2025LV: See PIntaIl bottle/VacuuM
systeM on page 13.
The tool is now assembled and must be lled with
hydraulic uid prior to use. Refer to fIll and bleed on
page 14.
PIntaIl bottle/VacuuM systeM
This procedure is applicable to models 2025V and
2025LV only; it should be used in conjunction with
the previous sections, general and head/handle. For
component identication, see Figures 5, 6, & 15.
1. Assemble adapter and tube/slide assembly (70) and
new O-rings (65).
2. From bottle side of end cap (21) install O-ring (69),
washer (71), wiper seal (23), wiper housing (67) and
retaining ring (66) as shown in Figure 6.
3. From spring side of end cap install O-ring (68),
spacer (22), and spring (19). (Figure 6) Screw the
entire assembly into the head; tighten.
4. Assemble the tube/slide assembly and O-rings (65);
slide the complete assembly onto the end cap (21),
and push tube into the connector (54). (Figure15)
5. Position the adapter (64) and pintail bottle (24) on
the end cap (21). (Figures 5 & 15)
6. Reach through the window of the pintail bottle (24)
and install the washer (63) and retaining ring (62) as
shown in Figure 5.
