9) Check surfaces of plunger
(16). Damaged surfaces
cause accelerated seal wear.
Deposits of all kinds must be
removed from the plungers.
IMPORTANT! Plunger
surfaces are not to be
damaged. If there are lime
deposits in the pump, care
must be taken that the drip-
return bore in parts (25) and
(26) ensure trouble-free
drip-return.
10) If the plunger pipe (16B) is
worn, remove tension screw
(16D) and remove along with
plunger pipe (16B). Check and
clean plunger surface (16A),
check oil scraper (16H). Cover
thread of tension screw (16D)
with a thin film of Loctite and
tighten carefully to 26 ft.-lbs.
(35NM).
IMPORTANT! Care must be
taken that glue does not get
between the plunger pipe
(16B) and centring sleeve
(16C). The plunger pipe
should not be strained by
eccentric tightening of the
tension screw or through
damage to front surface of
plunger, otherwise it is liable
to fracture.
11) After installation of high
pressure seals (23 - Note:
P422 and P423, also have
a support ring), place seal
adaptor (20) with weep
seals & pressure ring
installed, weep return ring
(25) and high pressure
weep return ring (24) over
plungers. Slide valve casing
over plungers and seat
firmly. Replace the 8
socket head cap screws
(34) and tighten to 35 ft.-lbs.
in a crossing pattern
(as shown to the right).
