14. Before replacing pump mani-
fold (29), first rotate crankshaft
(18) until two outside plungers
(24A) extend evenly forward.
Next lubricate v-sleeves (50) in
the rear v-sleeve housing (48)
and slide housing over plung-
ers. Lubricate ceramic plungers
with a light film of oil. Care-
fully and evenly slide manifold
over plungers and press
manifold firmly against
crankcase (1). Replace
manifold stud bolts (45),
washers (47) and nut (46) and
tighten to 35 ft.-lbs.
11. Inspect ceramic plunger (24A)
tips for wear. If necessary,
replacement of the ceramic
plungers may be accomplished
by removing the plunger bolt
assemblies (24B and 24C) with
a 13mm wrench. Ceramic
plungers should now slide off
the stainless steel plunger base
(22). Excessive resistance to
plunger removal may be
overcome by heating the
stainless steel plunger base.
This will melt any excess loc-
tite beneath the ceramic plunger
allowing easy removal.
12. Replace copper ring (24C) onto
plunger bolt (24B). Slide
plunger bolt assembly into
ceramic plunger (24A). Apply
a light film of loc-tite to
plunger bolt threads and place
plunger assembly onto stainless
steel plunger base (22) and
tighten to 105 in.-lbs.
13. To replace plunger oil seals
(26), proceed to “Gear End
Disassembly” section below.
Otherwise, continue as de-
scribed below.

9. If pitted or worn, replace inlet valve seats (36), valve
plates (37), springs (35) and spring retainers (34).
Re-insert items 34-38 into valve adapter (39). Install
valve assembly (34-40) into manifold (29). Reinstall
manifold plugs (43) and torque plugs to 50 ft.-lbs.

10.The rear v-sleeve housing
(48) may be removed by
prying evenly outward
with a flat screwdriver.
After slipping housing
over ceramic plunger
(24A), inspect seals (50)
and o-ring (49) and
replace as necessary. If the
crankcase is to be disas-
sembled, the housing
should not be replaced
until later.
