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. Remove the 2-piece shield (72) by inserting a
screwdriver straight into the slot, and using it as a
lever to release the tab. Repeat for all tabs. Do not
use the screwdriver to pry the shields apart.
7. 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.
8. 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).
9. See F
IG
. 2. Using a 1/2 in. hex driver, unscrew the
two cap screws (5). Remove the crank arm cap (38)
and key (39). If necessary, use a plastic hammer to
break these parts loose.
10. See F
IG
. 3. Rotate the crank arm (4) to allow it to be
removed from the output shaft (OS).
11. Pull the crank arm/connecting rod/slider piston
assembly (CR) up and out of the cylinder.
