PISTON PUMP
1) Loosen the stop plate (A). Remove the bolt and nut in the
protective cap and pull protective cap off (C). Remove the
two (2) allen head bolts (D) from the lever. The piston can
then be pulled from the cylinder (E). (See figure 1).
Also, loosen the clamp (F) and remove the hose.
2) Remove the pump cylinder by turning it counter-clockwise
from the bottom of the pressure cylinder. (See figure 2).
3) Check the inside of the pump cylinder and the piston for
vertical scratches. If the cylinder is scratched, replace it.
4) To disconnect the piston from the connecting rod, pry the
two (2) halves of the connecting rod apart with a flathead
screwdriver. (See Figure 4)
5) With a new piston, line up the connecting rod on the posts
inside the piston and on the lever. Snap the connecting
rods together. (See Figure 5).
