Disassembly
1. Jog the motor to bring the stand side lower to the
bottom of its stroke. This provides access to the
coupling nut (14).
2. Relieve pressure, page 2.
3. Shut off electrical power to the unit.
4. Remove the screws (12) and both covers. F
shows the cover (32) on the stand side; the motor
side cover is (21).

5. Place a clean rag over the top of the slider cylinder
(2) to prevent debris from falling into the slider
assembly during disassembly.
6. Place a 3/4 in. wrench on the slider piston (9) flats
(just above the coupling nut), to keep the slider pis-
ton/connecting rod from turning when you are loos-
ening the coupling nut (14). Orient the wrench so it
is braced against one of the tie rods (3). Applying
excessive force to the slider piston/connecting rod
can shorten the life of the lower pin bearing.
7. Using a 1-5/8 in. open-end wrench, unscrew the
coupling nut (14) from the slider piston (9) and let it
slide down onto the pump piston rod. Be careful not
to lose the collars (13).
8. See F
. 2. Using a 1/2 in. hex driver, unscrew the
IG
two cap screws (5). Remove the crank arm cap (38)
and key (39). If necessary, use a plastic hammer to
break these parts loose.
9
Place clean rag over slider cylinder (2).

Apply antiseize lubricant to screw (5) threads. Torque
key-side screw to 210-230 ft-lb (283-310 N•m) first, then
torque gap side screw to 210-230 ft-lb (283-310 N•m).
