Assembling the pump
NOTE: Use all the parts in repair kit 222–588 for the
best results. Parts included in the kit are marked with
an asterisk, (201*), in the text and drawings.
NOTE: Soak the packings in oil, and coat the rod and
inside of the cylinder with oil to prevent damage during
assembly.
NOTE: Alternate leather and plastic v–packings and
be sure their lips as face the direction shown in Fig.
14.
Incorrect installation damages the packings and
results in pump leakage.
1.
Check the piston rod (224) and the inside of the
sleeve (218) for scoring or scratches. If these parts
are damaged, new packings will not seal properly.
2.
Stack the piston packings onto the piston (222) as
shown in Fig. 14.
3.
Tighten the piston nut (211) against the piston to 10.5
in–lb (1.2 N.m.) to seat the packings, and then back
off and finger tighten.

4.
Note the alignment of the piston (222) to the piston
nut (211) and maintain this alignment through Steps
4, 5 and 6.
5.
Apply ONE drop of adhesive, supplied with the repair
kit, to the piston threads. Place the ball (225*) on the
piston. Hand tighten the piston into the rod (224) just
until the nut (211) contacts the rod. Place the flats of
the rod in a vise.
6.
Tighten the nut (211) onto the rod (224) to 19 ft–lb (25
N.m). Use two wrenches to maintain the alignment
as mentioned in Step 3.
7.
Stack the throat packings into the top of the cylinder
(219). Install the packing nut (216) loosely.
8.
Insert the piston rod assembly into the top of the
sleeve. Install the gasket (202) on the sleeve. Slide
the sleeve assembly into the bottom of the cylin-
der. Note that the tapered end of the sleeve is the
bottom. See Fig. 16.
