10. Assemble each cylinder block kit by installing piston
assemblies into the slipper guide. Lubricate pistons and
cylinder block bores. Install assembled guide and pis­
tons into cylinder block by inserting pistons into cylinder
block bores. The pistons and bores are not selectively
fitted, so no specific piston and bore orientation is
required.
11. Lay the pump on its side and install cylinder block
kits into the housing.
12. Install valve plate locating pins into center section.
13. Coat back (steel side) of valve plates with petroleum
jelly to hold them in position and install valve plates onto
center section, with their bronze faces visible. The notch
on each valve plate must engage its locating pin.
NOTE: Since the tandem pump sections are mounted
"back-to-back", each section will have a different valve
plate installed.
