CAUTION: Also inspect cylinders for linear grooving by
running your thumbnail circumferentially around bore of
cylinder. If any grooving is detected also replace
cylinders. New packing will rapidly cut or wear out in
grooved cylinders.
INSTALLING PACKING
Assemble V-Rings onto stud as shown. Lubricate the
outside of the assembly with Molykote or other grease
for ease in insertion – do not use a graphite type grease.
When installing each V-Ring assembly, rotate crankshaft
until piston rod is at forward position. Place copper
gasket 5030A128 in position in stud using a small
amount of Permatex to hold in place. NOTE: Apply
Loctite RC35 to capscrew prior to piston installation.
Follow instructions on label and make certain threads in
piston rod are clean and free of any grease or oil.
Assemble capscrew, etc., into piston assembly and
push into cylinder. Torque the capscrew to 50 ft. lb. using
a hexagonlal socket attachment
3/8" across flats.
REMOVING CYLINDERS, (Fig. 5)
1. First remove packing as outlined previously.
2. Rotate crankshaft until piston rod is in rear position.
3. Insert puller (3) through inside of cylinder and pilot over
piston rod.
4. Insert disc (4) into slots on puller (3).
5. Slip plate (2) over threads on puller (3) as shown.
6. Screw nut (1) on thread on puller (3) and snug up.
7. Tighten nut (1) until liner breaks loose.
8. Loosen nut (1) and slip disc (4) out of slots.
9. Remove puller (3) and repeat to remove other
cylinders.
CYLINDER INSTALLATION
Reasonable care and judgment should be used when
installing the new cylinder. Clean out any accumulation
of loose rust or corrosion in cylinder body. Install a new
O-ring in groove on tapered portion of cylinder, lubricate
O-ring with oil or grease for ease in insertion. Position
cylinder carefully by hand to avoid cutting the O-ring.
Drive into position firmly with a wooden block and mallet.
Never use a hydraulic press; excessive force can cause
damage and make cylinders very difficult to remove for
later replacement.
REMOVING SEATS: Wing Guided Valves
A. First remove valve caps, (61) and cylinder
caps, (72) which provide access to suction and
discharge valves. Remove the stainless steel cage
which serves as a valve guide and spring retainer.
Remove cage (65), spring (66), and valve (67), from
the pump fluid end. (Fig. 6)
. Suction valve seats are removed as above except
two stud lengths are joined using coupling
