if hard chrome is damaged. Inspect inlet valve seat (10) and
replace if cracked or worn. Inspect outlet valve seat (13) and
replace if damaged.
16.
Repair the fluid pump by using all of the parts contained in the
kit. For any other parts not included in the kit, replace those as
needed.
REASSEMBLY PROCEDURE
The pump adapter (19) should still be secured upside-
i
down in a vise.
1.
Soak the leather packings (21b) in hydraulic oil for 15-20 minutes.
Lubricate all of the other parts of the upper packing set (20, 21,
22) with hydraulic oil. Insert the female gland (20), the upper
packings (21) and the male gland (22) into the bottom of the fluid
section adapter (19).
Since the pump adapter (19) is upside-down, the
upper packing set will be installed accordingly, with
the peak of the "V" packings (21) pointing down.
Attention
After reinstallation, once the pump adapter is turned
right-side up again, the peak of the "V" packings will
point upwards. See fig. 27 for the final orientation of
all parts of the upper packing set (20-22).

2.
Insert upper spring (23); small end of spring must go toward the
packing set.
3.
Insert spring retainer (24).
4.
Install new O-rings (25a/25b) on the cylinder (12).
Lubricate all O-rings before assembly (Piston Lube,
i
Part # 314-480).
5.
Thread the cylinder (12) into the pump adapter (19). Tighten by
using a wrench on the flats of the cylinder.
6.
Soak the leather packings (17b) in hydraulic oil for 15-20 minutes.
Lubricate all other parts of the lower packing set (15-16, 17, 18)
with hydraulic oil. Install them onto the outlet valve housing (13)
in the following order: gland (18), lower packing set (17), gland
(16) and retainer (15).
The peak of the "V" packings (17) should be facing
downward upon reassembly.

7.
Reinstall the ball (14) onto the outlet valve housing (13).
8.
Coat the female threads of the displacement rod with adhesive
activator included with repair kit 240713.
9.
Coat the male threads of the outlet valve housing (13) with 4
drops of yellow Loctite 330 (included with repair kit 240713) and
4 drops of blue Loctite 243 (426-051).
10.
Thread outlet valve housing (13) back into displacement rod (27).
Torque to 120 ft.-lbs.
The outlet valve housing (13) and displacement rod
i
(27) should cure together for a minimum of 24 hours
before the fluid section is allowed to have any fluid
pumped through it.
11.
Insert displacement rod (27) assembly through upper packing
set (20-22) in fluid section adapter (19). Be careful not to scratch
the inner walls of the cylinder or pump adapter. Push the
displacement rod through until the end is protruding from the
20
top of the pump adapter (19).
12.
Remove cylinder (12) and fluid section adapter (19) from the vise.
13.
Reinstall the ball pin (6) into the ball cage (8). The ball pin has
two possible positions. The upper ball pin location allows for
more ball travel which is better for more viscous materials. The
22 lower ball pin location is for less ball travel and is better for less
viscous materials.
14.
Install the O-rings (11 x 2), ball seat (10), ball (9) ball cage (8) and
the O-ring (7) into the foot valve (5).
15.
Thread the foot valve (5) into the cylinder (12). Torque to 250
in.-lbs (+/- 75 in.-lbs).
It is not necessary to overtighten foot valve and cylinder
i
into fluid section adapter. O-ring seals perform sealing
function without excessive tightening. Full thread
engagement is sufficient.
16.
Reinstall the fluid pump. Line up the fluid pump to the bottom of
the pump block. Thread the locking nut (26) onto the hydraulic
motor and tighten.
17.
Reinstall the two coupling halves (fig. 26, item 4).
18.
Slide the O-ring (3) over the two coupling halves to secure them.
Slide the coupler sleeve (2) over the O-ring (3).
19.
Reinstall the front cover (1).
