The adjustment screw allows 15 turns
of adjustment over the timing range.
The adjustment screw should be
turned 20 turns counter-clockwise to
insure you are starting at minimum.
Note: You can not adjust below
minimum -additional turns counter-
clockwise have no effect.
Each clockwise turn will equal approx-
imately.3 seconds. Add the number of
turns clockwise to reach the approx-
imate desired timing. Some additional
adjustment may be necessay depend-
ing on the accuracy needed.
Use the light on the cycle timer to help
in setting the time. The light will turn on
when there is power going to SV2.
TROUBLESHOOTING
Itthe following procedures do not
correct the problem, contact afactory
authorized service center. When
submitting equipment to be repaired,
be sure to state the nature of the
problem and indicate if arepair cost
estimate is required.
PROBLEMS
CYLINDER PRESSURE GAUGE
DOES NOT REGISTER PRESSURE.
A. No system pressure to the pump.
B. No 24 VDC signal at solenoids SV1
and SV2.
C. Pressure reducing valve set too low.
Increase setting by 1/2 turn to check
operation.
D. Primary solenoid valve SV1 may be
inoperative.
PUMP PRESSURE BUILDS VERY
SLOWLY OR NOT AT ALL.
A. No pulsing signal at SV2.
B. Pressure reducing valve maybe set
too low.
C. Grease viscosity maybe too high for
temperature at which pump is
operating.
D. If pressure is not building at all,
secondary solenoid valve SV2 may
be inoperative.
E. Pump piston ball checks and inlet
checks may have foreign matter
trapped causing leakage. Remove,
inst)ect and clean if necessarv.
F. Inspect sealing surfaces between
upper and lower inlet checks.
Replace if rough or pitted.
G. Replace shovel rod if rough or
pitted. Replace shovel rod packing.
H. Inspect lubricant supply line for
leaks or breaks.
1. If hydraulic vent valve is used, check for
clogged orifice. (Refer tow 3&w6)
DISASSEMBLY
Refer to SERVICE PARTS for part
numbers and location. Bleed all
pressure from hydraulic and grease
lines before disassembling pumps.

Disconnect hose assemblies
(241 806 and 241 963) from upper
portion of the pump.
Remove cylinder adapters and
gaskets (241 961 and 24181 O).
Remove bolts and washers securing
cover to pump (50058 and 48083).
Remove cover and valve assembly
(241 799 and 84970).
Using two wrenches, unscrew
coupling nut (241 805) from pump
shaft end (11329).
Remove four upper bolts (50771 )
and lock washers (681 86) securing
mounting plate (241 803) to the tie
rods (241 804).
Remove hydraulic cylinder (241 814)
and moun{ng plate (241803).
H. The hydraulic cylinder can be

disassembled f;om mounting plate
by removing four bolts (242048) and
lock washers (681 86).
Tie rods (241 804) can now be
removed from pump outlet body
(40537) by removing four lower bolts
and lock washers (50771 and
681 86).
Unscrew pump tube from outlet
body (40537).
Extend txImtI lIiston rod (11340) out
of the bottom of outlet body (40637).
Place wrenches on piston end
(11329) and flats of piston rod
(11340) and unscrew piston rod.
Thread the piston rod through the
gland packing to allow removal of
the pump tube.
L. Unscrew gland packing nut (12333)
from outlet body and remove all
gland parts.
M. Remove the priming tube (61275)
from the bushing extension (61273).
N. Extend plunger rod (11723) out of
bushing extension and unscrew
priming plunger (11724) to allow
removal of priming check parts and
plunger rod (11723).
O. Remove bushing extension (61273) ~,
and unscrew plunger and bushing
assembly (90554) from pump tube.
Unscrew coupling nut (11345) from
plunger adapter (11344) to allow
removal of plunger and bushing
assembly intact, reducing the
chance of loosing ball stop (57027)
and check ball (6601 O).
ASSEMBLY
To reassemble, perform DISASSEM-
BLY procedures in reverse.
IMPORTANT
To prevent damage to pump gland
packing and to help increase
packing life, lube pump piston rod
before assembly. Thread piston rod
through gland packing when
assembling pump.
